Great service and great people!! Took my work van to get transmission fluid, drain and fill. I was in and out that shop. Definitely bringing my other vehicles over as well read more

Sam was very helpful. He always answer my calls and is very insightful. Last year I got a transmission rebuild on a 2011 RAV4. It has been great so decide to get my 2002 Ford Explorer done here. The explorer was jerky only after a cold start so we tried going with a smaller fix before doing a full rebuild. I was quoted around $1k. It took around 5 days before I got my car back. He gave me a warranty of 2 weeks, full credit towards a rebuild, or after 2 weeks for 6 months, it would be $500 credit. The car was driving fine except during traffic so I had to bring it back in to get the full rebuild. It costed around $3k but I paid $2k since I got the $1k credited back. It has been a week, and the car has been fine since then. I recommend Leeco Transmission as they are very honest and kind. Sam was always friendly and does a good job. I believe they have employees here who speak mandarin or korean if needed. They do not have parking here, you just drive your car in. read more

SERIOUS CONSUMER WARNING - DOCUMENTED TRANSMISSION TEARDOWN AFTER "REBUILD". I brought my truck with its 4L80E transmission to this ATRA member shop for a full rebuild. The owner, Mr. Lee, stated he has 43 years of experience and that he personally performs all the rebuilds. I paid him $2,850 and supplied an additional estimated $1300 in quality brand new parts, which he inspected and agreed to install. For context, I have 20 years of experience working on vehicles and am a certified diesel mechanic. The main reason I brought the transmission to a shop was that I didn't have the space nor resources at the time to perform a full removal, installation, and rebuild myself. Communication was polite initially, and the owner appeared willing to work with the parts I supplied. He was also extremely fast and did the actual rebuild in half a day. The transmission failed three separate times within three weeks, requiring removal and reinstallation each time. After the third failure, I towed the truck home and completely disassembled it myself. During teardown and measurement, I documented multiple serious assembly and quality-control issues, including: -Wrong pump installed, despite being told no hard parts were changed -Intermediate clutch pack assembled with incorrect clutches, leaving clearance nearly three times outside specification (which can prevent the clutch from holding properly and lead to rapid failure) -Sun gear installed upside down, blocking a critical lubrication hole required to supply oil to internal components -Several worn bearings, steels, seals, and other components appeared not to have been replaced -Reverse band misadjusted to the point the output shaft would not rotate in any gear The FIRST failure was caused by a transmission fluid leak from an old 180k-mile pump bushing and seal that were not replaced. The SECOND failure was explained to me as transfer case and transmission cracking as soon as Mr. Lee shifted into Drive.. the shop claimed it was caused by my driveshaft despite it being the original factory driveshaft with new, unbound U-joints. The THIRD failure caused severe transmission overheating (never disclosed to me) during Mr. Lee's 5-mile test drive, with a claimed valve body diagnostic code that never appeared when I scanned the truck myself. Because this truck is critical for my cross-country towing work, I ultimately spent three months in very difficult circumstance personally performing a very slow but full transmission teardown in order to rebuild the transmission correctly. I have extensive photos and video documenting all findings of why this transmission had repeated failures in a span of three weeks. If proper assembly, reliability, and accountability matter to you, I strongly recommend choosing another shop. read more

I brought my 2013 Nissan Versa in for a second opinion because the dealership (where I thought my new transmission was under warranty) quoted $10,000 to replace the transmission AGAIN and replace a few other parts. Lee and Sam took the vehicle for a few hours and got it running again for a fraction of the price. They determined that the issue was not related to the transmission. Their willingness to listen, inspect, and be transparent was most striking. I'll definitely be back. read more

Leeco Transmission - Fixing transmission leak on my truck - Transmission Repair Near Me - El Monte, California

Late post...Stopped in to Leeco Transmission to check on what I think was a slip in 2nd gear.. I have a 14 year old Ranger, used I just bought.. Waited until Mr. Lee came back. He hooked up his little machine, and off he went. He came back and said he didn't find a thing. I went with him and of course, nothing happens when someone else is in the truck.. He went on the streets, freeway and nothing. He checked the oil level and said it was clean.. Bottom line, he didn't find a thing, said it was ok.. So no charge.. I think Mr. Lee was honest and will return when I definitely need him.. read more

The transmission on my 2007 Toyota RAV4 finally gave out after 289,000 miles. At first, I thought about junking the car-it's old, tired, and has definitely served its purpose. But with the cost of new cars being so high right now, I decided to patch up the transmission and squeeze a couple more years out of it. I called around to several transmission shops, and most quotes were between $4,000-$6,000. Honestly, I couldn't justify spending that much on an eighteen-year-old car. Things were looking pretty bleak until I found Leeco Transmission in El Monte. Sam, the mechanic there, is one of the chillest and most straightforward guys I've met. He's honest, hardworking, and gave me a repair cost well below the other places I had called. The job was done right, and I'm thoroughly satisfied with how my RAV4 drives now. God forbid your transmission ever fails-but if it does, I highly recommend taking it to Leeco Transmission. Ask for Sam. He'll take care of you, fix your car, and save you money. read more

My Camry almost hit 200k mileages. Still going, hopefully can hang on two more years before I get my new car. Thank you Leeco Transmission.

Excellent service great work and my truck runs amazing and they beat everyone's prices

Leeco transmission is amazing their turn around fantastic and their pricing is more than fair I have a fleet of Chevy and fords whenever the transmission goes out I send it to these guys they do solid honest work I'm glad to have found them would 100% recommend to anyone who has transmission needs read more

Great guy come see him easy to talk to and willing to help out. Need help and good price this is the spot

I came here for a transmission rebuild. I got a free diagnosis and did not pay till after the job was done. Sam was amazing -- he kept me company, always answered the phone, and made sure I was updated every step of the way. You can tell he genuinely cares about his customers. Will update this post as I use the transmission read more

This is an honest-to-goodness review from a repeat, legit, and very satisfied customer. Back in 2019, Toyota quoted me almost $7,000 for a transmission replacement. I knew I couldn't afford that, and someone told me about Leeco Transmission in El Monte. I gave them a try, and Mr. Lee and Sam changed my whole transmission for about half the price. The work was fast, smooth, and my car never gave me problems after that. Fast forward to 2024--my check engine light came on right before my smog test. I knew I wouldn't be able to renew my registration unless it was fixed, so I went straight back to Leeco without even thinking twice. I explained everything to Sam, and once again, they took care of it. They even charged me the same amount as years ago despite prices being higher nowadays, which honestly meant so much. After a few days, I was able to pick up my car, go straight to the smog test, then to the DMV, and renew my registration with no issues. A few months later--just a few weeks before the one-year warranty ended (because they do have that and it's legit)--the light came back. I went back to Sam and Mr. Lee, left the car, and let them do their work. My car stayed for a month and I didn't complain or get mad. I didn't bother them or rush them because I know transmissions are complicated. There are so many processes of elimination involved, so no, you cannot rush them if you want thorough work. Your safety relies on your car, and mechanics taking the time to fix your car carefully--without you hovering over them for deadlines--matters a lot. So, no complaining or bothering on my end. I wanted them to take their time and find the problem. They kept checking everything one by one until they finally found it. It had nothing to do with the parts they fixed last year, which were still under warranty. After a few weeks, which was exactly today, Sam finally called me with a happy tone and said the car was ready. They replaced the computer, only charged me for the part and labor, and that was it--no surprises, no extra fees. My car runs so smoothly again just like the day I took it home from the dealer 18 years ago. Same thing as when I changed gears, smooth transition. By now today 8.20.25, I've been here three times. And what really stands out to me is this: not once did they bring up pricing or charges right after I explained my transmission problem. We don't even talk about money until I start asking how much will everything cost and how long will it take so I can make ride arrangements. Even then, I'll politely ask Sam if he can help me out with a discount. Without hesitation, and always with a genuine smile, he does. They never make demands about pricing or up charges. The first thing they do when you bring in your car is run diagnostics right away and focus on solving the problem. That's when I realized--they didn't earn their reputation by nickel-and-diming customers. I trusted them with my old 2008 Corolla, and they gave it their best every single time. They've always delivered with respect and honesty. I've never once had to compare prices or haggle, other than asking for a small discount, which they gladly honored. To give you an example of their generosity--this last visit, I dropped off my car with the gas tank on empty with lights lit and all. When I picked it up, it was almost quarter full, and they never even mentioned it or charged me for it. Their work is also backed by a one-year or particular mileage warranty ( I forgot how many ) - whatever comes first. Mine was still under warranty by just a few weeks, and they didn't charge me anything for fixing what was covered today. The only cost was for the new computer, which was a separate issue. And here's something else that makes them different. Most car places, the owners just pass the work to their team of mechanics. But here, right beside Sam's office, you'll always see Mr. Lee himself doing the work--even the drive tests. Sometimes he has one guy with him, but often it's just him fixing your car. Who does that nowadays, where the actual business owner is the one under the hood? It's clear this business isn't run by money but by his passion for the craft, even as a senior citizen. Amazing mechanic, amazing customer service, and an amazing business. Hands down, Mr. Lee, Sam, and the whole Leeco Transmission team have my respect. They're honest, kind, and they stand by their work. To me, bringing my car here always feels like asking a trusted friend for help. If you come in with politeness and honesty, you can expect the same treatment back, not just from Sam and Mr. Lee, but from people in general. read more

I had down shifting issues with my 2002 Toyota Highlander and found Leeco Transmission on Yelp. After carefully reading their customer reviews, I took my car to their shop to see how much it would cost to repair or replace the transmission. Mr. Lee and Sam ran diagnostics and found sensors had failed which was also why my engine light was on. My other mechanic I usually go to recommended a transmission rebuilt which would have cost $2,500.00+. Mr. Lee and Sam were able to repair it for much less and so far, no issues with down shifting and I am able to drive it to work without worries. If this car can last for another 1 or 2 years, I can't ask for more since this is a 23 year car with 215K miles. Both Mr. Lee and Sam were very helpful and honest individuals so with transmission problems, I would highly recommend Leeco. read more

Even though my Honda hr- v couldn't be fix they did the best they could and were very professional. This was a cvt transmission that was a piece of junk for most cars. I would definitely bring another car back here. Thank you. read more

Thank you Lee and Sam! read more

Leeco rebuilt the transmission on wife's 2013 Lexus ES350 over a month ago and it's been running smooth since. I usually do basic maintenance myself, but I seek professional help when I know there's something wrong inside an engine or transmission. Lexus/Toyota says the trans fluids are "lifetime", but of course there is no such thing as lifetime. They make it especially difficult to change/refill the fluid so never changed it until after ~120k miles. After about 5 months, wife complained the car didn't want to move from stop until engine revved and trans suddenly caught on. I'm no mechanic so assumed maybe the trans fluid filter is getting clogged, so changed the fluid a 2nd time (failing to get the pan off due to 1 bolt above frame that's not reachable with normal tools!). Would hear some soft slushy grinding sound in 1st gear, then silent once into 2nd. After getting a shallow swivel socket a week later, finally was able to change the filter and the 3rd fluid change! Was expecting to see some metal shavings on the pan magnet, but there were also pieces of metal chunks, like small rods (needle bearings)?!?!!? Drove to the market and car now would NOT shift into reverse at all! Multiple shifts and tries and restarts later, gave it a good dose of gas and it caught into reverse. Shifted to drive and drove home, but the car was making a much louder slush grinding sound all the way. I raised the white flag/surrendered and searched for transmission shops. There are couple around La Habra that seemed ok or pretty good reading over all the Yelp reviews. But Leeco Trans, although some 40 mins drive away, stood out to me as my best bet, because there was 1 or 2 reviews mentioning Lexus/Toyota transmission, while other shop reviews didn't. I wanted to take the car to a shop with experience on the U660 transmission and Leeco ended up being my choice, especially considering the owner, Mr. Lee, has been rebuilding trans for 4 decades! Called into 2 other shops, but felt Leeco probably had the most rebuilds on Toyota transmissions. Estimates were all in the same ballpark, there is no accurate estimate until trans is opened to see what's broken (mine had chewed up gears that got replaced so ended up on the higher end of the ballpark). The Lexus felt and drove smooth going to the shop, like the ailment that disappears when you arrive at the doctors office. Mr. Sam greeted me and I explained what I had done up to now and the symptoms and showed the pieces of metal that I cleaned out from the trans fluid pan. He explained the case to Mr. Lee and Mr. Lee took the car for a test drive to see if he could experience the problem. But of course the car was purring this day. Mr. Lee came back and said if I didn't show him the metal pieces he wouldn't think anything was wrong, lol. We left the car with him to go ahead and open up the trans and see what's happening on the inside. Well, things were pretty chewed up inside! Mr. Sam kept me updated on status and once trans was fully open and diagnosed, he sent me pictures of the damages Mr. Lee found. Told them to please go ahead and replace damaged parts and rebuild the trans, since I expect the engine is good to go another 120k miles easily since did the PITA spark plugs just few months ago! Took couple of days, mainly due to waiting for replacement parts, but Mr. Lee got it rebuilt and back in the car, maybe took a week in total. Car drove smooth and trouble-free again! Don't really appreciate Lexus/Toyota until you drive something else for a week, lol. The next weekend when wife pulled out of garage, I noticed there were some drops of fluid on the floor! Wiping it up, I knew it's the trans fluid (reddish)! A quick panic attack and when wife came back, I went ahead and jacked up the car to go under there again (tired of the transmission area after so many times, lol). The transmission looked clean, but saw some fluid maybe around the trans pan gasket area. Texted Mr. Sam and he responded even on his day off to bring it back in and will check and take care of it. They found a bad gasket that did not seal the pan properly, so went ahead and replaced with a new gasket. Mr. Sam kept me in the loop and he wanted to leave the car up overnight to make sure the new gasket will not leak. Confirmed it's good the next day and picked up and it's been dry and driving happily ever after:) Leeco trans in my experience has been trustworthy and honest, it's everything I would want in a transmission shop. Mr. Sam is responsive by phone and text to keep you updated. Mr. Lee is an unassuming gentleman that packs 40 years of transmssion experience, what more can I ask for!? Mr. Lee personally rebuilds each transmissions himself, just has guy/s remove/reinstall the transmission that he seems to disassemble/repairs alone. Maybe even other shops send cars to Leeco? since I saw more cars on each visit and Mr. Sam always getting calls and he tells them bring it in! LOL! read more

Leeco charged me $2000 for a rebuilt transmission job on a 2000 ford mustang v6. 10 days after the job my transmission blew out again and had to take it in AGAIN. ....and AGAIN. I ended up selling off the car because I was tired of constantly taking it back for the same transmission issues. Had an another auto shop look at the job they did and he said the job Leeco did looked slopped together. read more

They are great people , honest and reliable. I was having issues with acceleration and speed. Did the whole check up and diagnosis free of charge and let me know it wasn't a transmission issue at all as I expected. They are kind and understanding of one's position. I highly recommend they work thoroughly. read more

My 2nd time using Leeco, this time I brought in my 1984 AM General ice cream truck. The transmission was shot.. wouldn't go forward at all.

I brought my car in for a second opinion on the transmission and they were very helpful. They worked on diagnosing my car right as I showed up and were able to give me an answer in about 20-30 minutes. Sam sat down and explained to me the code that my car was showing, what it meant, the part that was bad, and the resolution. They did not even charge me a diagnostic fee, which was very kind. I appreciated Leeco Transmission very much and will take future cars back if I ever need transmission work again. read more

Scion Xb was not passing its Smog check, so I came here looking to get my check engine light + TCL off. Lee took my car for a test drive to see what issues could be causing my dash to light up. A full transmission service + speed sensor was recommended, I was able to bring it in for same day service and now my dashboard is cleared from any lights and car runs so much better. Leave to Sam and Lee to take care of any transmission issues you may be having. They got years of experience to back up their professional and top notch work. The price was absolutely fair for the quality of work they do here. read more

Sam and the owner were honest mechanics and that's hard to come by. Unfortunately I needed a rebuild but they tried a few things forts to try and save me money. They also diagnosed it on the spot and didn't charge a "diagnostic fee" great experience all around read more

Mr Lee is very helpful and knowledgeable. Fixed the transfer case issue on my 2013 Sequoia and 4wd system is working again now

Wells its hard giving someone 5 Stars when you just paid $2,300 to repair your transmission BUT the truth is these guys did a great job and did it pretty quickly. I turned in my car late afternoon before Thanksgiving and got it back early Tuesday morning. Mr Lee and Sam were both great to deal with. Honestly, this was not the lowest price I received but the other place that quoted me took it to a guy who would rebuild it and they would install. Here at Leeco, they do it all in-house and I was willing to pay a couple extra hundred bucks to make sure I get the right job. First car in 30 years of driving that needed a tranny, hope its the last. read more

Came in on recommendation for a transmission job on my 2016 Tahoe. Was quoted an average price and average turnaround 4-5 days. After 6-7 days go by I call to check the status and was informed that something is wrong and they have take the transmission down to check it again and it will be 4-5 more days. Ok fine. 6-7 more days go by and I get a call around noon that my truck is ready to come pick it up. So I drop everything and make arrangements to do so. Get to the shop no explanation from the owner on what the reason was for now having my car for almost 3 weeks. At this point I don't care. Get in my car start driving maybe 3-4 mIke's when I noticed my transmission is still jumping around 2nd gear. I try to ignore it but call the shop anyways to tell them what is going on. They tell me bring it back and they will check it. So I bring it back and go on a test drive with the owner and his laptop where he says nothing the whole time yet we can feel the trans hopping at the same speed and rpm. Get back to the shop and he says no codes to let it "acclimate" for 10 days. Fine. I get halfway home again on the freeway when the rpm's go through the roof, lose power and have to limp off the freeway and back to the shop. Owner says good check engine light is on 4-5 days. Long story longer, finally got my car back and now it is leaking from the back trans case. I have messaged the owner about it with no response. At this point I am exhausted with this shop. Needless to say I would not recommend this shop to anyone. read more

Once again Mr Lee, Sam and Jhon did a great job with figuring out why my engine light was going on. I've said it b4 and I'll say it again. You want great work, honest people and awesome work.. Then bring it HERE. read more

Leeco Transmission - Transmission Repair Near Me - El Monte, California

On October 19, 2024, my 25-year-old BMW 330i's transmission failed to reverse while trying to park in a spot. I have been expecting this to happen for many years now. Before this happened, I knew of Leeco Transmission of El Monte, which has an excellent reputation by reviewing Yelp Reviews. An hour before they closed, I called and spoke with Sam and arranged to have the car towed the car on Monday, October 21. I met Sam and Lee, and they gave me a quote and four days to work on the vehicle. On October 31, Sam called and told me the car was ready. For some reason, I felt very confident about Sam and Lee and their reputation. Lee was kind enough to pick me up, and I had a chance to learn more about him. Happily, I paid the agreed amount and left. Driving the car home is very surprising to me. I was surprised by the transmission's performance after owning this car for 25 years and doing all the maintenance myself. They gave me a two-year or 20,000-mile warranty, and I am confident the transmission will outlast that warranty. I will go back there for my other cars! Thank you so much, Sam and Lee; it is good to know that there are people like you in the automotive industry. read more

You wrote: "you left happily with your vehicle to the recollection best of my memory." yes i did. wholeheartedly agree! but only because i thought you did the repair i paid for!!! LOL! your rationale or refusal to stay within the context of this thread is unbelievable! i will repeat what i said on my previous reply. you did not do the repair i paid for! yes i put 9000 miles on my car. but it still doesn't justify the fact that you didn't do the repair i paid for!! there were metal shavings in my fluid for goodness sakes! you say you aim to provide exceptional service. but when I outline what wasnt done. you ignore or sidetrack your reply for justification of said action word of caution to future customers. upon return of service of your car after repair. ask the mechanic to pull a sample of transmission fluid from the drain plug. it will tell you 75% of what you need to know. your fluid should show hints of red read more

Do you miss the old days when an older gentleman would warmly greet and diagnose you car? Or how about a mechanic who stands behind his work and honors his warranty? What about a car tech that will go out of his way to help you? If all this sounds what you are looking for then give Mr. Lee and Sam a try. They will take care of your transmission's needs and offer a nationwide warranty (an extra fee of course). I have been going to Mr. Lee for over a decade and he always take care of the problem and if the issue is not the transmission he can lead you in the correct direction. read more

Leeco Transmission - Transmission Repair Near Me - El Monte, California

In September 2019, My Honda was slipping. I knew it was my transmission because I had this problem many years ago. Dreading another big repair bill, I checked with my regular mechanic and he said that it will take about one week because he was going to send it out to his transmission specialist. That was going to cost $$$$K! Well, Thank God for Yelp & Leeco Transmission!! I called them on a holiday and Sam answered the phone and was very helpful. Took my car in the next day and Mr. Lee gave me a very reasonable price and a very good warranty. Got my car back in 3 days! As of now, June 2020, I haven't had any problems with my transmission. Thank You again Mr. Lee & Sam!! read more

Mr. Lee and the crew are awesome! We recently bought a car and of course weren't to happy when we felt the transmission slipping. We remembered Mr. Lee from a long time ago when he diagnosed an issue with another one of our cars and brought it to him. So happy we made that decision. My hubs and I couldn't b happier. They rebuilt our transmission and did an outstanding job! Car really does feel brand new now! Thank u all for being so on top of it. Great communication and service. I'd recommend him to anyone! read more

Thank you to Sam and Mr. Lee for helping me out!! My car was acting up, and I thought it was because I lagged on getting an oil change, I take it to a local mechanic and told him to do an oil change and tune-up. I advised him of my issues (keep in mind this is another transmission shop). He "supposedly" performs the oil change and tune-up. Then calls me to tell me that he is done, but when he took the car around the block...it was slipping. He wanted to keep it overnight to look into the matter. The next day, he calls me to tell me that it is the transmission and it will cost in the ball park of $4800. My heart fell into my stomach...what was I going to do?? Luckily I researched the matter and found Leeco Transmission. They looked my car over, gave me a very detailed diagnosis (complete with pictures that Sam texted me). Mr. Lee worked with me on the price because let's face it...people don't normally have a couple thousand lying around. I agreed and 2 days later, I had my car back. So far...so good! My car drives so much better and I am so thankful. Totally recommend Leeco Transmission for any of your transmission needs! read more

These guys rebuilt the transmission to my 2002 Toyota Camry. It costs me under $2500 which was similar in price to other garages but this place also includes a warranty of their work for 3 years. Other places didn't provide any warranty. Overall, they are professional and seem to do a great job at an honest price. I've had my car for 6 months with the rebuilt transmission and have not had any issues. I even drove to Las Vegas and back with my car loaded with people. If you need transmission work, these are the guys to go to. read more

These guys are awesome. They took the extra time to correctly diagnose my slipping transmission. At first they thought a fluid change and service would do the trick, but kept it an extra day to make sure it was fixed. As I thought and was told previously from my mechanic the second gear sycros were done. They didn't charge for the fluid service and promptly rebuilt the transmission. The communication and pricing was clear and accurate. My car is a 2007 Lexus ES350 but they work on all types of transmissions. It has been over 5k miles with no issues. Thank you. read more
