I brought my car in because the transmission light was on. Got a call from the owner who took it upon himself to call to check my warranty (I assumed my warranty was up). Turned out it expired 18 days from then, so he called the dealership and gave them my vin number and I was able to get it in no problem. They also reset my oil light when the other mechanics I went to forgot to do it, free of charge. I feel like a company with less integrity would have just done the work instead of doing that for me. They proved themselves trustworthy and I will definitely go back!

I first went to Belmont-Watertown Transmission in August 2018 for a pretty major transmission repair, and I've been doing all my repairs and regular maintenance there ever since. I am a mechanical engineer working in the automotive industry and I also work on my own cars and motorcycles, so I am knowledgeable enough to understand what a technician is talking about when they describe a problem with my car. Every time I have gone to Belmont-Watertown Transmission, Joe Arria and his team have been transparent, straight-forward, and honest with me. I have now had them do a transmission rebuild, fix belt noises, do several oil changes and tire rotations, and do a full front brake job (pads and rotors). Their work has all been top-notch. I've been to several different shops in the past, and I always enjoy going to see Joe because I trust him and his team with my vehicles. Joe and his technicians are world-class, and really nice, friendly people as well. I've been to other shops where they try to rush me out as quickly as possible, but Joe and his techs are always willing to take the time to explain what's wrong with my car and answer all of my questions. I have gotten to know Joe and his team pretty well over the past few months, and I really admire how they do business. When I walk into the shop, everyone seems happy and proud to be working there, which tells me that Joe treats his employees as well as he treats his customers. I can't say enough good things about this shop and I really enjoy going there. I highly recommend Belmont-Watertown Transmission for all types of car repairs.

This is a fantastic, full-service, repair shop. They re-made my transmission and replaced my muffler. In both experiences, they were honest, fast, and communicative. Joe is a consummate professional who is reliable and truly cares about his customers.

Highly recommend! I can't recommend this place enough! If you're looking for a mechanic you can trust this is it. I brought my truck to the dealership with a transmission issue where they charged me $900 for diagnostic just to tell me they didn't know what was wrong (seriously). Joe had it pretty well sorted out over the phone based on the codes and symptoms. He was very transparent with the cost and really went the extra mile with service and communication. My truck was sorted out for the price and on the schedule we discussed. I will use this garage again and I have and will recommend to a friend. Thanks again!

A small Christmas miracle running into the guys at Belmont Watertown Transmissions! After visiting 3 tire places for an emergency repair of what was likely a nail or some kind of puncture in my tire, they came to my rescue. All tire places were so booked they couldn't assist with my tire for another 1-2 days. I was only in town for work with a full day scheduled ahead, and was debating my options. The gentleman at Belmont Transmissions said they could help and could take a look at it right away. Sure enough they took the car right in, and found a razor blade in the tire tread! They patched it up quickly, filled all the tires, and I was good to go. It held up for a full day of visits in Boston, and a 2hr drive home. Still holding fine today as well. They helped restore my faith in honest, first-rate tradesmen (and people) in the world. I would recommend them highly for any car service needed! THANK YOU!

I have been to this shop twice and have been so impressed! They definitely will have my business as long as I am living around here. Joe (the owner) is so friendly and professional and so reassuring to someone who knows next to nothing about cars, like me. He will call before he does anything to make sure you are fully aware of what they will be doing, why they are doing it, and exactly what it will cost. He will also give really honest opinions on what does and doesn’t need to be done right then which has helped save me money. I am so glad I have found such a reliable mechanic so close to where I live!

Joe is great and so are the mechanics . Fairly priced and highly knowledgeable mechanics. Joe is on top of his game with the transmissions / rebuilding . All my vehicles are serviced here for transmission, oil change , brakes, down to suspension work . They do all kinds of repairs. Very professionally mannered, friendly and always takes the time to answer questions about the repairs, labor, warranty and products etc. I won't be going anywhere else .

Everything you've heard about Joe and his business is totally true, whether it be from Yelp or Google Reviews! I first went to his shop in 2016 for a rebuilt transmission on a Honda Odyssey, and last week I brought my Volkswagen in for work. Once again, I left feeling confident in the quality of the work. This guy is legit - he's honest, transparent, and just really good at what he does. In 2016 he took the time to answer all my questions and show me the inside of a transmission and the parts he uses. He goes above and beyond for his customers and really knows his stuff. I am particularly impressed with how Joe has established his car care business on the foundation of honesty. From my previous experiences, I have found that achieving this level of honesty is not always a common occurrence. However, Joe has demonstrated an ability to make honesty work in his favor, and customers have taken note of it, resulting in their appreciation and loyalty. It's a pretty cool and thoughtful business strategy. It was his father's shop (or may still be I'm not sure) prior to him managing it and I'm guessing his father was a pretty good guy too. It's nice to find these neighborhood owner/operated shops that do amazing work! Their name is Belmont Transmission but he and his staff can handle anything you throw their way that has to do with cars. I went initially for a transmission issue but afterward was delighted to know they could do it all. I take every problem to Joe. Highly recommend! Todd Fix

Joe and his team were fantastic to work with! Flexible drop-off and pick-up, pricing for the transmission was way better than other local shops, and he worked with me on timing of payment. Overall, this is what you want when your car runs into issues; a shop where you can feel you're not getting screwed.

Joe and his team are incredible. I was originally referred there by a trusted mechanic/friend to do a transmission fluid exchange and filter change. Not a month or two later unfortunately my transfer case went out so I reached back out. They got my truck into the shop within a couple days, diagnosed my issue and discussed my options. The price was extremely fair and the work was top tier! Highly recommended

Fixed my car that was randomly stalling and slipping by replacing a cooling line when other shops told me it was the whole transmission. Great work.

I recently bought a (replacement) van (Ford E350) which I use when I'm out on tour with a group of musicians. Only three months into ownership I got the bad news that my radiator busted and ruined my transmission, needing to replace both. This was less than a week prior to starting an eleven day- nine gig tour. I made an appointment at Belmont Watertown and they got me in as quickly as they could. I needed than van by Wednesday at the latest, they stayed late and got it back to me on Tuesday! I drove that van for over 3000 miles in those eleven days, throughout Ma, CT, NJ and NY. It ran like a charm! I would recommend them to anyone looking for transmission work. That they understood my situation and made the extra effort to get it done ASAP makes me a lifelong fan!

I found this place when I had a car in need of a transmission, and they replaced it and at the time everything was gravy. Cool, I would go here for a TTRANSMISSION ONLY. My opinion outside of transmissions, go spend your money somewhere else, I had a misfiring cylinder which ended up clogging my catalytic converter which caused my car to run like crap. They fixed the cylinder for a pretty penny, wouldn't touch the cat for under another 2 grand saying it wasn't related to the misfire. They were the ones to diagnose why my car wasn't running. I ended up buying an amazon cat replacement for pennies on their dollar and the car was fine after that. Fast forward to my recent car, I needed two front struts when I bought it and I had this place do the work. They put these struts in June 2025. Its October 2025 and they were all squeaking and making noise when I turned the wheel and went over bumps at slow speeds. Because of my last interaction with them I ended up replacing them myself with the OEM replacement part made for my car from Rock Auto, and the struts that were on my car were not the correct size. Maybe its the cheapest aftermarket part you can buy for the car so its not as strong but my front end lifted over an inch, the bolts are even bigger where it mounts to the chassis with the OEM replacement compared to what they put in. I feel like I wasted my money to have my car "fixed" for 3 months. Go here for a TRANSMISSION ONLY

I bought a 20 year old Toyota Highlander with over 175,000 miles on it in great shape. The transmission needed work since it stuttered a bit between second and third. Belmont made the transmission hum and found and fixed a few other things that needed attention. The price was lower than I expected. I now have a car that will go for another 175,000 miles.

Even before I get into my own review, I'd like to remind the reader: it's quite rare to find an auto shop with a high rating. Belmont Watertown Transmissions came highly recommended by my neighbors, and I'm so glad I trusted Tina and the crew with my car. They fixed up my completely dead car and charged a great price. They were responsive, transparent, and so kind. I love that there is a local shop I can trust. Cannot recommend more!
