    Fixing transmission leak on my truck
    Jesus A.

    Mr Lee, and sam Best in the business, been my To go guys for all my transmission Problems , there very knowledgeable And good (best) pricing I recommend them percent good people

    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!

    "The Best in the West" Having a family run a small business like Lee Co.Transmission of El Monte for the past (40)+ years wasn't easy dealing in Los Angeles County. Sure there's ups and downs in every business, and absolutely I've been through all kinds of places for a transmission rebuild and/or replacement throughout my life. Been there and done there, like having servicing at the local VW DEALERSHIPS and not to mention AAMCO!!! I've been overcharged and legally robbed by those HUNGRY, THIRSTY and GREEDY places that I've just mentioned. Last week I hit the sidewalk on my GERMAN VW. Oil immediately leaked all over shopping center. I knew immediately that the transmission oil pan was hit and cracked!!! I HATED EVERYTHING AT THAT MOMENT, nobody to blame except myself... Called AAA next morning and got it towed back to my house. Next morning, I called the VW Dealer of Downtown L.A. wherei bought that car... ESTIMATE = $1,600 Started calling every mechanic shop in El Monte... Prices estimated? $1,400 $1,400 $1,200 $900 I figured since I'm dealing with transmission, call transmission SPECIALIST!!! Mr. Lee answered, (YANABASEEYO) and transferred the call straight to his business manager by the name of Sam!!! I told him my situation... Sam beat ALL THOSE PRICES that I've mentioned, and took the job right away... Said BRING THE CAR NOW!!! After car arrived with AAA to his shop around 12:00pm Was hot 100* outside, I said I'll go get a bite at McDonald's down the street... I left at 12:30pm to McDonald's... They never said anything accept, take your time Greg. I came back at 1:30pm WTF ??? I couldn't believe my eyes. Car was running with the A/C on. Boss said, go take it for a test drive, I took off on the (10) freeway right around the corner. Ran better than ever!!! SMOOTH OPERATOR!!! Came back with a smile, paid the money without any bla bla and bla... I asked one question from Sam and Mr. Lee Why so fast? How??? Everybody claimed it'll be 2-3 days, plus expect some other BS from others. Maybe some other issue... I was ready to buy a KY-Jelly just in case. "THEY ARE HONEST & THE BEST IN THE WEST" They said that their shop is equipped with every part and accessories on premises!!! I will ALWAYS recommend them. Thank you Thank you and God Bless you guys...

    If you need a transmission rebuilt go to Leeco..if you need an ice cream truck for an event let us know Chilichilimango.com

    Our family's Ford Explorer required a water pump replacement…read more I visited several local auto shops to obtain quotes and was shocked, disappointed, and discouraged at the prices I was being quoted for the work my vehicle required ($5,000-$7,500) Shame on me for not reading Yelp reviews before wasting my time visiting other auto shops. I read the many positive reviews for Hye-Tech Auto Repair and decided to visit them. Upon entering, I was greeted by John (owner) with a friendly, "Welcome, how may I help you?" I explained that my Ford Explorer needed a new water pump and a few other items that other auto shops had advised me would require repair or replacement. While John looked up a few items on the computer to provide me with a quote, he introduced me to his son, Harry, who happened to be in the office. Thirty seconds later, John provided a quote that was $3,500-$4,000 less than the other shops. I could not believe it. John explained that he makes his living and succeeds in his business through repeat customers, and he does not believe in gouging customers for every last penny. He also shared that when he retires, his son Harry will take over the business, and he wants to leave Harry with a solid foundation of loyal repeat customers. It was then that I knew I could trust John and his son Harry. John went on to explain that replacing the water pump on a Ford Explorer was a 10-12 hour job, as it was an internal pump requiring numerous engine parts to be removed to reach it. This was the same thing all the other shops advised me. John suggested that I leave my vehicle, and he would perform a full inspection of the engine and contact me before doing anything to it. I agreed and left my vehicle. The following day, I was contacted by John, who advised me that the water pump did indeed need to be replaced, as it was the source of the constant leaks of the water coolant. I left my vehicle in John's shop for three days. During this time, John or his son, Harry, contacted me numerous times to keep me updated on the progress of my vehicle and also to point out that mechanics had discovered two or three very inexpensive items (under $50.00) which they recommended replacing, which I agreed to have done. All in all, I was and am extremely impressed and satisfied with everything about this shop. I spent much less money to have five different issues repaired on my vehicle at Hye-Tech than what I was quoted to replace my water pump alone by every single shop I visited prior to coming to Hye-Tech. John and Harry are very friendly, honest, and trustworthy. They are also very knowledgeable and experienced, and they offer GREAT customer service and communication. This is my new go-to shop for any issues involving our family vehicles. Thank you, Hye-Tech Auto Repair, for a very positive experience.

    I opened a Yelp project to try to get my transmission serviced. The dealership wanted to charge me…read more$1300 for this service. Yelp projects are one of the best things I've ever experienced. It's nice to see you can get quotes at the touch of a button on your phone. This morning, I had time off, so I headed in to get my service done. I did not have an appointment and that did not seem to matter. I arrived first thing in the morning at 8 AM and ask if the service could be done. Harry was an exceptional young man, he took me in with no problems, no questions. He said they could do it this morning. I told him I would have to wait. He had no problem with that either. Prior to bring in the car in this morning, as I said, I used a yelp project and had several people reach out and give me quotes. After looking at all the yelp reviews I decided to give this place a try. I am super happy that I did. This place is a hidden gem, excellence, service, quality, and value for what you receive. There are not very many shops where you could feel comfortable and put your trust in them. As I spent time in the lobby, I was able to see customer service on the phone and customer service entering the facility. Every customer that walked in, seem satisfied and was treated with dignity and respect. I highly recommend this place if you have any automotive questions whatsoever.

Second was a 2002 Yukon Denali, needed a transfer case rebuild. Just recently my wife's Dodge Durango had been giving us problems. Turns out it wasn't the transmission, but the TCM solenoid. With Angel's honesty, attention to detail, and great work ethic, I've had all repairs done correctly, with minimal downtime, and not being ripped off. He explained all issues so a non-mechanic as myself can understand. Thanks again Angel!

This is basically the 2nd worst thing that could happen to a vehicle IMO The job did take time but I made it work with getting around. Angel and his team did have to do some trouble shooting because this specific transmission requires the valve body to be primed on the bench prior to installation. He rebuilt the entire core and also changed out the engine rear main seal. Now, the transmission feels better than ever. I had to give him a little bit of a hard time about not having Zelle which he ended up getting after. Overall I would say, he really does care about taking care of his customers and will make sure the job is done correctly.
