M & R Transmission is San Diego specializes in auto transmission repairs. This shop was highly recommended to me by Eli European Auto. Spoke to the owner Mario who was able to accommodate my car transmission removal and replaced. I had my car towed here and Mario and his staff Rhonda and Miguel were all professional and helpful. The surrounding area is rough but the shop assured me my car would be secured. It took about a week to complete the work and the cost was more reasonable than at the MBZ dealer where they quoted me triple the amount. I waited over a couple months before posting this review just to make sure all was good. If you own your car and it's beyond the warranty coverage and the transmission goes out, I suggest you call Mario for the job. Recommend read more

See all

I took my BMW to M&R Transmission about a month ago for a transmission fluid change. I usually wait a few weeks before writing a review just to make sure everything's running smoothly afterward--and I'm happy to say my car's been running better than ever since the service. I called several places before deciding on M&R, and most shops just gave vague answers or high quotes without even looking at the car. But when I spoke to Señor Mario, the owner at M&R, he explained everything in detail, gave me a reasonable price using OEM parts, and made the whole process easy and trustworthy. The service was quick--faster than I expected--and both Mario and his wife were super friendly. They even gave me a military veteran discount, which I really appreciated. Overall, I trust these guys completely and would recommend them to anyone in San Diego (or even beyond) who needs transmission work done right. I'm definitely planning to bring my '98 Jeep there next time. Thanks again to M&R! Muchas gracias, Señor Mario! read more

I took my car to them in March of '25. They gave it a quick look and said they couldn't do the work. They recommended I take it to Lou's Auto in National City. This ended up being a horrible recommendation. When I notified Mario about this, he tried to justify Lou's negligence. I can't say I recommend this shop. read more

AMAZING mechanics. The whole shop is Great. Friendly. Quick and done right. My 1989 Nissan D-21 needed to replace a bad drive shaft. So I just ended up redoing my clutch. resurfaced. Boy. Feels like a brand new truck. I will be sure to recommend everyone here. ‼‼‼ Thanks. J.Ramos read more

Absolutely love the staff and service --- and of course the fair prices. From the front desk lady to mechanics Miguel and Mario they always do great work and they always call ahead if any changes in price may occur. Honestly no matter where you live in the SD area -- get your vehicle over to them. I Trust them 100% I've worked on cars from the ground up myself and they've never tried to bs me --- straight up talk and pricing. read more

If you're looking for a mechanic to take care of your car and not rob the bank. This will be the place. Honest and upfront! No BS here! Husband and wife team that will get you up and running. Thanks Rhonda and Mario!!! read more

Mario did a wonderful job getting my 2001 Expedition ready for Smog. I had lots of leaks in the vacuum system and a faulty EGR. M & R installed new vacuum hoses and intake gasket kit along with the EGR. Also helped me identify that my voltage was being robbed by my stereo and onboard air system which interfered with O2 sensors that work off a fraction of a volt. Not my first time going here and not my last. I send my family here. Very knowledgeable people working here. Thanks Mario and Rhonda. read more

Had a few issues with my car a few months ago, my mom referred me, if I would've known about them before I would've been going to them for all my repairs. They fixed my transmission, cats, many other things and I can't thank them enough! Thank you so much Mario for all your help with my car! Definitely know where to go for all my repair needs from now on! read more

This place is the transmission shop you've been looking for. They're honest, affordable, and quick. Also they're a sweet "mom & pop" style business that you should be supporting. read more

Its so hard in todays world to find a vehicle mechanic that doesnt make you feel violated when you get the bill. I found this pkace on Yelp when my clutch exploded yesterday. I called and Rhonda answered the call with great concern and pleasantries. She gave me the number of a reliable tow service, they can quickly, towed me in to the shop, and was surprisingly economical. Everyone was friendly and professional. They all ask how I was, which, well, shitty to be honest. They all laughed at my response. They estimated the clutch by the time I got back to work, told me it would be ready the next day, and by 5pm the same day, they called to say it was ready. The owner did the work himself and did a great job. They gave me a 12 month/120000 mile guarantee. After reading their business card, I noticed that they also are full servuce mechanics in addition to transmission experts. My vehicles have found a new home. Thank you Mario & Rhonda at M&R Transmission read more

Friendly, diagnosed the problem within minutes, didn't talk down to me (oh yes, I've had that happen), ordered the part and installed when he said he would - all with a smile! Couldnt ask for better read more

This shop provides great service. I have taking my car here for years. They are dependable and honest.

A million thanks to Mario and Rhonda for saving my 2007 Xterra! There is a long version to this story as is with any car/truck with a transmission problem, but after my truck bounced around a couple shops with nothing but headaches, I got referred to Mario by a friend. ~~I do not want to get into what shop did what on the internet but I can tell you there are slimy places of business that fix transmissions. You basically are at their will because you need your car and with a transmission problem they can basically do what the want as your only choice is to fix it at there business or retrieve the car and pay the expense diagnosing Fees.~~ M & R transmission is NOT one of these places. With one phone call to Mario I immediately felt better about my whole situation that had lasted 3 weeks already. I went to the shop where my Xterra was and paid the $600 Diagnose fee : ( to get it out of there ASAP and over to the good hands of Mario. My wife was always Skeptical about getting the truck fixed and just wanted to junk it, and was not happy about the $600 we already had to pay at the slimy shop on Convoy but together we went into M&R to drop off the Xterra and after we did she was like, wow I love Mario and Rhonda and I really feel good about leaving our truck here. I highly recommend getting a quote from M&R transmission when you have a problem and your shopping around. Not only that, but talk to Mario on the phone and you will see how honest and knowledgeable he is. Rhonda was proud of the fact that he had been working on transmissions since he was 16! Wow guys, thank you SOOOO much. Its been over a month and she runs better with 130,000 miles then she did when we bought her with 30,000 miles!!!! read more

M&R are the best! Mario and Rhonda run a great shop. Rhonda is exceptional at her job and very knowledgeable about the business and time frame in which your vehicle will be done. They don't cut corners and the price point is right on. This business is word of mouth and there is a reason they have a 5 star rating. I would take my cars anywhere else. I can't say enough about this amazing shop. Stacey read more

I took my vehicle to get a heavy duty clutch out in and it came out of their shop feeling amazing. After, I had them install an after market radiator, radiator shroud, and after market fan. They raised my radiator after I had a previous shop not do that and perfected the cooling of my truck once again after I dropped a body lift! I also threw in a short throw clutch and they torqued it down for me once I heard some rattling going on! I recommend this shop 100% for price, quality of work and turn around time. Friendly owner who knows what he's looking for if something is wrong and will walk you through everything they did if you have no mechanical experience so know the work being done. Glad I found this shop and won't take my truck no where else to be worked on! read more

Great customer service and it was a quick turnaround for a lot of work. Thank you, Mario!

I was in San Diego for a week and my transmission went out, really didn't know what to do or where to go so I looked up the closest shop from where I was at and I was lucky to go find this shop! They took care of me and fixed my car for a decent price! read more

Other shops charge a lot more for their parts and services whereas M&R Transmissions finds you the best deal.

M & R Transmission - Transmission Repair Near Me - San Diego, California

Mario and his wife are great! I needed to swap the transmission in my lifted diesel. I dropped it off mid day Monday and it was done Tuesday afternoon. He was up front on the price and kept his timeline which is always a delight when dealing in the mechanic world. I'm not discussing the price, other than to say he is very fair and it is worth it. If you need an honest and decent mechanic in the San Diego area Mario is certainly the right person to call. read more

Was having transmission issues on an old car and was nickeled and dimed by other mechanics. M&R took me in the test drive to ensure I understood the actual problem that they were able to diagnose immediately. They were completely transparent and quick in my quoting process and admitted to me where I could save money but risk future problems, and vice versa. They laid out all my options and I felt comfortable doing what was best for my car without spending money where it didn't need to be spent. And a military discount! Recommend! read more

These guys were great. fixed my diesel truck which couldn't go into reverse and had it ready for me much faster than I would've expected. Even upgraded a few things that most shops would have charged a lot more for. I hope I don't need to come back anytime soon but if this place will be my first choice read more

I went to m&r because they are very close to where I work and they are GREAT! Mario has kept my old jeep and my daughters car running like a charm. Their prices are fair,usually lower than anywhere else and they always back up their work. They get the job done by the time they say it will be done, no waiting and waiting like some places I've been to. This is a great place to get your car fixed!! read more

I urgently needed catalytic converter replacement so I could pass smog for my Acura. My regular mechanic said the job was too big for him so my co worker recommended M & R Transmission. I got a great estimate and Rhonda was accommodating getting me in at my convenience. Mario and crew got the big job done in one day. Very friendly and professional folks. Atmosphere was friendly and supportive. I highly recommend this shop for any automotive needs. They took care of my 2007! read more
