My truck was back on the road and drove it all the way up to Mammoth and back without any issues. thanks read more

I ended up buying a car off fb marketplace and got a vehicle in horrible condition. Bought a 2012 Toyota RAV4 and after 60 miles it shot a transmission code. Brought it into the shop and they offered a repair but recommended a replacement due to the code that popped. They shopped around and found a transmission in good condition for a great price so I went with it. After they looked at the car more they realized it didn't even have a Toyota transmission. Someone had replaced the transmission with one from a camry. I got quoted on transmission replacements from a few shops and this shop offered full replacement, including mismatched parts, for half the price of any I contacted. If you are having transmission troubles I couldn't, in good conscience, recommended anywhere else but here. From the service, friendly nature, explanation of issues in a way I understood, and letting me have the final say and what repairs to make, there isn't another shop I would ever go for transmission issues. Also took only about 9 days(including weekends) where I didn't have my car. That includes them diagnosing, hunting down a transmission for me, ordering parts, and installing. Honestly quicker than I expected! read more

They say they'll call you to make an appointment but never do. It's text message game

Was referred to A Transmission Clinic from my regular mechanic and wasn't disappointed. My son's car AT & engine light came on over spring break and the timing couldn't have worked out better to have a repair done. Owner Fernie was honest and very professional with the inspection of our car. Both him and Angel preformed the work in a timely manner and even showed me the bad parts pulled out of our car. We shopped around to confirm price quoted on the part and found them very reasonable given the supply chain issues. After all we were just glad, they were able to find out part needed. The car runs like new....I highly recommend using A Transmission Clinic! :) read more

Not sure why I waited so long to write a review, maybe Im a bit skeptical when it comes to dealing with mechanics. I was at the point where one thing after another was going wrong with my vehicle. After taking it to several different shops and either they didnt fix it or in the case of the transmission they made the problem worse. But thank God I found Fernie and A-1 . It was around 8 months ago and since he worked on the car i have not had a single problem he fixed everything and I would highly recommend this shop. It is so rare to find a mechanic who takes pride in his work. read more

My daughter was visiting from Las Vegas when her Yukon transmission went out. A transmission clinic quoted a very reasonable price and had it out in three days. read more

Angel and Fernando are the real deal. I am leary and suspicious of all mechanics. They just have a bad reputation and I have been burned. It's hard to find a good one, a trustworthy one. This place has a more then one! Angel has serviced my transmission issues not once but TWICE and both times were quick, on quote and I won't bring my transmission problems to anyone else. Even if I moved out of Corona, I would still bring them back here. This place is the best. Don't shop around just bring it to Angel and you will get taken care of correctly. His dad, Fernando trained him well. Thanks guys. Customer for life. Scott Burnett. read more

The customer service it's horrible, specially with the son's owner. He has a bad attitude and treat me like I was doing him a favor, not as a value customer, besides he was very rude, that's not the way to response to a client. Definitely will not trust this guys to fix anything in my car. read more

Good quality service and work. Very professional and reasonable pricing. Got a transmission fixed and they gave me a 1 year warranty or up to 12 000 miles read more

I've used A Transmission Clinic two times and both experiences were positive. The first time was when I had a 2004 Buick Century that started doing hard shifts. I had a mechanic at another shop tell me that I need to rebuild the transmission. Fernie said he thought changing the transmission fluid and adding an anti-slip additive would solve the problem. That worked and saved me big $$$. The 2nd time was a simple transmission fluid change on my 2010 Camry which went smoothly. My car was in and out in one day and the cost reasonable. They do other types of repair work which I haven't used them for yet but I wouldn't hesitate to use them. Also, everyone is very friendly. I give A Transmission an A+. read more

Fernie did a great job rebuilding the transmission on this classic 1955 Thunderbird. It now drives as it should! Thanks for doing an awesome job! read more

A Transmission clinic is THE best. I was worried about what we needed done and the costs. Kathy was very reassuring, explained the work in detail, the value in what needed to be done and eased my mind. They delivered on time and no surprises with added costs. Angel showed me what was repaired and I'm confident in their work. The thought of needing transmission repair has always scared me. But it wasn't that painful when working with a great company like A Transmission Clinic read more

It was pleasant to find out that this is a family operated business. Fernie is extremely knowledgeable when it comes to older transmissions and classic cars which is hard to find these days, and he personally owns a Chevelle. I just don't leave my 66 Mustang with anyone, these guys are very trustworthy. They completely rebuilt my C4 transmission with high performance parts to help out my already beefed up 289. If you have a classic car and need transmission work done, this shop is where you wanna go. read more

I have a 2006 Lexus GS 300 and this was the first major issue it's had. My car was tugging before stopping pretty bad. Because of his experience with transmissions Fernie already knew what was causing it. When it was completed there was an issue with one of the parts and Fernie didn't feel comfortable giving the car back to me. He worked out with the parts manufacturer and had another new sent. This time that did it and he saved me from having to rebuild the transmission. During this process he was updating me on the process. I would recommend A Transmission Clinic to anyone need transmission work. The cost wasn't bad and the problem was taken care of the first time. Thanks Fernie saved me from having to buy a car. read more

This is the best place for transmission work! I have needed their expertise for two different cars over the past 4 years. I now know that they will also do my brake job! Simply the best mechanic ever! read more

These guys did a fantastic job om my Toyota Sequoia! I was told by Larry Miller Toyota in Corona I need a new transmission, $4,500.00 approx. I was told by a transmission shop in NORCO... that I should get a new transmission/ rebuilt for about $3,500.00 I was really uncomfortsble with what both were tellung me and trying to sell me. I decided that I should probably get a third opinion/quote. I reached out to, A-Transmission in Corona for a third quote, as soon as I started talking to Fernie, I felt much better. I explained the issues that I wss having, and he gave me 4 possobilities, 1.) Was a transmissions service... $200. 2.) Change or rebuild the modulating valve 3.) Rebuild the transmission $3,400.00 4.) Get a transmission from a salvage car...one with no significant damage, that pricing would be from the wrecking yard. Fernie recommended the service to me, he said he would be checking for metal shanings, burnt fluids, etc.. if everything looked good he would change the fluid an all associated/ parts. I did choose the service option, Fernie said everthing looked good except for the fluid was low, replaced fluid buttoned up the transmission, and I had my car back in about 4 hrs. I paid $193.00 the service, the Sequoia, is now running great, i could not believe the difference. For that amount I spent, I am going to have my transmission serviced, from here on out, every 50K miles. Based on my experience with the others, it will be mone well spent, for that piece of mind. The difference that I see between A- Transmission and the others, Fernie is a true mechanic...professional, who actually tries to diagnose the problems, and then only fix what is necessary. These other guys just were interested in swapping one transmission for another. I am really glad I found them! From here on out, I will not go to anyone else, for any future transmission services that me or any of my family might need. read more

Fernie (not Ernie or Bernie) but FERNIE :).. is a honest & very kind person/owner. We took our 2017 Pacifica in to see if the slippage/delay in the gear shifting was worth repairing or if it's characteristic of front wheel drive. He said it would probably get worse with time (most do) but to service the transmission would not really help it. Most people would service it & take the $250-$300.00 charge- he said it would not help that problem & it was not a rush replacement. I'm taking the time to announce this because these kind of service stations & technicians are rare & hard to find. Kudos to FERNIE (I think it's short for Fernando). If & when the transmission gets to the point where it will no longer function, ATC will be our 1st choice. read more

A Transmission Clinic was referred by a a friend, best referral ever. They are ASE Certified and very nice. My car's transmission oil was changed in less than 1hour. read more

I recently went to A transmission clinic a few weeks ago to get my 2000 Chevy Silverado 1500 transmission fixed and the experience was very professional, fast, and reliable! I've had no issues with my transmission and truck since and it feels almost brand new! They installed a new transmission unit and fixed my oil leaks by replacing my seals and gaskets in only 3 days! The recommended torque converter really helps make the difference too. I've had other friends use this business and also have great experiences so if you're looking to get your transmission fixed or replaced definitely come here! This has to be the best transmission shop in Corona and the owners are very honest and trustworthy, they walked me through the process and even fixed a delay in my transmission display. Definitely come here and I will be back for any transmission issues in the future. They even included a warranty in my order in case anything goes wrong but I doubt I'll have to use this. You're money will best be spent here for a reliable and top of the notch service! read more

Thank you Fernie and Kathy for your professional service and special attention! Even though you were unable to do work on my daughter's car, you made sure we were taken care of with the Ford dealership and gave us some good information that we needed. We really appreciate your time and consideration. If needed, we will be back to do business with you again and will definately be referring our friends and family. Thanks again! read more

I been here twice for the same problem, my transmission coil were overdue for a change, they were quick to order the parts I needed and get me back on the road as soon as possible. The owner is super friendly and showed me what was wrong with my car. read more

I came into A Transmission Clinic for the second time because my transmission on my 2004 Mazda truck with 300k miles on it finally broke down. The first time I went here was about 6 months earlier when I needed to have the slave cylinder replaced on the clutch; I chose Fernie because he was the only mechanic that wasn't charging a ridiculous price. Fernie is certainly one of the most affordable mechanics in town (I've done my diligence and checked almost all of them!). However, this doesn't mean that he does cheap work, rather, it means he finds cost-efficient solutions to save his customers money. For example, he allowed me to bring my own slave-cylinder instead of having to order one from a place that would mark up the price of the part--most mechanics will not do this. Fernie and his son are really friendly people and treated me like I was family. Having been only partially employed for the past year, at the time I was extremely low on funds. When I had my truck towed to him with a broken transmission, I was candid with Fernie and told him that I didn't have the money to pay him the $1228 needed to replace the transmission but he insisted on fixing it for me anyways on a promise that I would somehow get the money by the time repairs were done. Sure enough, after Fernie was all done putting in the transmission, I was able to get the necessary money together by borrowing from people and an Ebay sale. However, I was short about $28 which Fernie allowed me to pay later. It's been about a month and the transmission still works great! He specially picked a really solid tranny to put in my truck which came from a rollover vehicle so it was still in pristine condition. I've remained loyal to one mechanic in Corona since I was 18, before learning about A Transmission Clinic. Fernie has just won my business for good! You can't beat a mechanic who is honest, reliable, sympathetic to your financial situation, and most importantly does high quality work! I have recommended him to my close friends who have all told me that he has done an excellent job on their cars! Fernie is the man for the job, don't even think about taking your car anywhere else! read more

If I could give them 10 starts, I would. Fernando is the Man... He replaced my Transmission Cooling line and my Titan and runs like new again. He was very helpful and answered all my question with a high level of professionalism and customer service. Totally recommend them. Tell him Fry Weezie sent you.. read more

I've been to many mechanics, thinking I found a honest shop, sorry to say no, but finding this place was a GOD SEND. Talking to Freddie and having him work on my cars, even if it's not a transmission issue, was a great find. Friendly people Fair deal Very thorough AND MOST OF ALL HONEST read more

Car was giving me a rattle and I wasn't sure what it was. Went in and got it checked out, turned out to be cracked mounts for the engine and transmission. Mechanic explained everything to me and showed me what he found. Got it fixed within a day and haven't had a problem since. read more

If you are looking for an honest, reliable, and professional transmission shop, A Transmission might be the place for you. I blew a clutch in my 1964 Corvette that had only 6500 miles and 9 years on it. Quite disappointing. The team at A Transmission was accommodating and got me in right away. The quote that Fernie gave me was accurate and he finished installing the new clutch on the day promised with no added charges or surprises. The difference between the previous and the new A Transmission clutch has made a big difference in the drivability of the car. Much Better!! If you are looking for the cheapest shop, or one that might bait with a lowball initial quote only to surprise you with extras, A Trans is not your place. If you want quality work at a fair price, call them up. read more

Bernie is a wizard when it comes to transmissions. I have a scanner and a transmission code came up I called Bernie and he guided me in the right direction. He told me to clear my codes and drive it around and bring it into his shop. He then checked my codes and everything was fine he looked under the hood check fluids and told me to get out of there. I'm headed on a long road trip and you could have charged me for anything and I would have paid. Honesty is hard to find in this industry give Bernie a try read more

This transmission shop doesn't deserve even 1 star, here's why: I noticed my vehicle needed transmission servicing by a professional. Although this place claims to have specalists, and will even sell you on the idea of their supposed 5 star ratings, this place was the wrong choice. I specifically asked them to diagnose my transmission problem. They assured me it was the motor and transmission mounts. Their diagnosis was soley based on them driving the car . Later I learned elsewhere that my vehicle could have been hooked up to a diagnostic computer for proper/professional diagnosing. They charged me $600.00 to repair the problem. I had a suspicion that this job was over priced. I confirmed that by going to another mechanic who could have performed the repairs for $365.00 parts and labor and a 6 month warranty on same. Once, they completed the job in which they claimed they had to dismantle the trans. and engine, they told me I needed a new transmission and then offered a so called discount by offering to replace the transmission for $1150.00. That's more than the value of my car. Talk about the old bait and switch. Where do you find these people? Guess they saw me coming a mile away, or maybe they were looking for some extra Christmas money from the next sucker. Do your homework before trusting these guys and their assertions. read more

Fernando and his team are the best! Very friendly and very honest. His pricing is so much better than the large corporate auto shops. His honesty shows through in his work. Also its not just transmissions, he does all auto repair, a true mechanic. read more

I am so happy for the amazing work this guys make to my Chevy Suburban. Thank you for your professionalism I definitely Recommended, thank you Kathy to be so nice. read more

I was initially impressed with this business. The owner Fernie and his wife were cordial and personable and the cost to rebuild my transmission was reasonable. Everything went well until my transmission started leaking heavy when it is at an incline. It has only been a little over a month since Fernie rebuilt my transmission. If I would have known then what I know about how they run their business I would have never gone there and given them my hard earned cash.....The warranty that I was told I have only applies to what they want. It is self serving to them. I was told I would have to pay an additional $275 to repair this leak. All seals and o rings should have been replaced. The o ring is a $2 part that should have been replaced when reinstalling the transmission. My suburban never leaked transmission fluid before I had it rebuilt. A rebuilt transmission should operate like a brand new transmission and new transmissions don't leak. I am also a Corona business owner and I would never treat my clients unfairly like this. I believe because I am a woman I was treated unfairly. I am very disappointed and would not recommend this business to anyone. read more

My friend recommended me to take my truck to a transmission clinic Fernie gave me a good price and great service. My truck runs better than when I went in the shop . I also had some other work done. Thanks Fernie my truck runs great read more

I called and spoke to Fernando, Fernie, after going to a local shop in Brea and having them tell me I need to go to a transmission specialist. Fernie right off the bat seemed like a good guy, and he proceeded to go into detail after I had described my cars 'symptoms', and he told me what I needed to do. He actually had the heart to tell me to see if my car had any recalls and take it to Toyota. Now what car shop is going to pass up a sale to defer it to the dealership? I eventually took it to him because there were no recalls, and he didn't even work on it because miraculously the problem went away when I got there. Crazy thing is no work was even done, but you can guarantee if I have issues in the future Fernie's integrity alone will make me a customer for life. Plus, when he quoted me initially it seemed extremely reasonable. Check it out. read more

Had my transmission serviced.. best quoted price around. No hassel, I was in and out in a reasonable time.

I had taken my suburban to 3 other places with some outrageous quotes. Funny thing none of them even knew what was wrong with my car. Called this place and they towed my car for me and had me a quote that same day explaining to me what was wrong. Picked my car up and it drives better then when I first bought it!!! I will definitely recommend this place to everyone read more

Great service, very respectful and honest; I enjoy doing business with the owner and staff.
