Mario is a great mechanic. He is no nonsense and gets the job done. I would highly recommend him.

The best mechanic and most reasonable professional in the area. I highly recommend. Ask for Mario.

I found R&S Transmissions when I called another shop. My wife's PT Cruiser needed an oil change and her car's brakes were making squeaky noises. Turns out that the first shop only works on imported cars but they strongly recommended R & S Transmissions. "A transmission shop for an oil change & brake check?" I asked. Sure, they replied, "R & S Transmissions can do whatever you need." It turns out the R & S Transmissions is a general service auto shop. When I called R & S Transmissions, Mario, the shop mechanic said to bring the car right down. He performed an oil change and brake check while I waited for $21, not including tax & disposal fees. A very good price. In checking the brakes he determined that the PT Cruiser had a slightly warped front brake disk. The warping would cause a little whining when the brakes were applied but wouldn't affect brake function. If we could live with the noise a brake job wasn't necessary. The mechanic was accomodating and willing to handle our job on no notice. He completed the inspection and oil change in about half an hour. His price was fair. And, he was able to identify and honestly diagnose a problem without trying to sell us work that we didn't really need. I WILL be back! R & S Transmissions is easy to miss. It's located in a small industrial complex on MacArthur Drive, south of 11th Street and north of Shulte. read more

Brought my car in because it was shaking when I accelerated. Mario performed some initial diagnostics with the computer interface and found nothing. He then opened the hood and looked at my transmission fluid...I had very little. He did not have my special transmission fluid in stock and ordered some immediately. I was welcome to wait, but decided to walk to a local restaurant. When I returned, the car was waiting for me out front. Mario greeted me and told me to take the car for a drive and let him know what I thought. The shake had gone away. I returned and asked how much I owed him. He said nothing! It only needed the fluid. I wanted to pay him for his time and the fluid he had ordered, but he refused. I will recommend Mario and his company to all of my friends! Thanks, Mario!!! read more

This is only my second time writing a review, but i had to with how amazing the customer service was! My car broke down on the way to LA for the weekend. I called them at 445 and told them we'd be there in the tow truck in 30 minutes and they stayed open late to take my car. They also knew I needed my car the first thing Monday morning for work so they made sure to make it a priority over the weekend. They also opened early Monday morning to return my car so i could make the 2 hour drive and only be mildly late for work. On top of that, the part they ordered me from their supplier ended up being bad, but I didn't find out until I had driven back home. Living 90 miles away, it world be inconvenient for me to get my car back to them to replace the part. Instead, they had me take it to my local guy and paid for everything to be replaced in full. They're so thoughtful and honest. read more

Great team of people who treat their customers like family. I'm very appreciative of this family run business that operates at a very high performing level. Professional, courteous and personable. This shop got my car up and running and were able to did my issues so I could also pass smog! read more

These guys were GREAT! I came in today with no appointment. My car had been making this strange squeaking noise when I would brake for a LONG time and even the place I had gone to get the brakes done originally, told me there was nothing wrong. I was getting tired of everywhere I went being told nothing was wrong and that my brakes were good, so I went to R & S today and they hooked me up!! They took it for a drive and about 40 minutes later the mechanic, I think his name was Mario, had me come out and get in the car and no more squeaky noise!!! On top of all that he didn't charge me!!! I am a SUPER satisfied customer! read more

Mario was very helpful and was able to reset an airbag light on my 2001 porsche in minutes and didn't even charge me. Another shop in Livermore told me that they needed the car for a minimum of two hours. read more

These people were so helpful and so nice in helping me figure out if I needed a new battery or a new alternator. They tested my battery for free and determined I needed only a new battery. They had a battery brought over in 10 minutes, put it in for free & only charged me what the battery cost. What more could you ask for?!?! LOVE this shop! read more

The only thing I can tell you is, this guy is honest. That's the most important thing in finding a mechanic - someone who will tell you exactly what you need. I was on my way home (to Sacramento) from East Bay when my car started having acceleration problems. I was recommended to him by a Tracy resident, since I didn't know any car shops around. When I got here, he noticed that I drove a Subaru. It's one of the two cars he doesn't really work on. But, because I was here and the tow truck driver had already dropped the car, he asked to pull the car into the shop so he could take a look. It was throwing a code p1578 which in the Subaru world, could be anything. He toom the car for a spin to get the feel of what I was talking about. He, then, put the car up and checked my catalytic converter, which was definitely the case upon further diagnostic through my mechanic. As busy as the shop already is, Mario took the time to accommodate me. He called other shops that works on Subaru & recommended me to a muffler shop that was close whom he had good relationship with should the catalytic converter be the issue. After, checking everything that took a little over an hour, he still didn't charge me. He wanted no money from me at all. The best I could do for him is write up a review of what customer service should be. Even though he lacked the tools to fix and/or diagnose my car, he still went out of his way to try to figure out what he could. I'm beyond impressed. Thanks again, Mario and the R&S shop. read more

Had a great experience here!! Mario is very trustworthy and good at what he does. My AC was out for over a year and no one could seem to find out what the issue was or they wanted to charge me much more than I was comfortable paying as a full time college student. Happy to say that Mario found the issue quick and charged a very fair price, I'm loving my fixed AC!! (: read more

Just an update, after R & S losing this case in San Joaquin Court, they ignored all requests to pay this debt they owe. I had to use a sheriff to collect a small portion of this judgment, but to this day Mario and R & S Transmission has still not paid the majority of this debt they still owe. read more

I have had my jeep serviced here for multiple issues. One major headache was the motor fans electrical switch relay shorting out every 6 mos at $500 a pop. M&M auto repair tried 2x on my dime and a 3rd time on their dime and when the switch went out on the 4th time R&S fixed it and its been 2yrs without issue. He does all my work when it comes to my jeep. read more

Stopped by r&s transmission to get my clutch replaced, was not sure what to expect upon arrival but after talking to the mechanic Mario he ensured me what was wrong and got me squared away with a quote. I brought the car back a few days later to get the work done, I was expecting it to take 4-5 days but boy was I wrong! He had the car ready to go by the next day!! Great work!! I will definitely be back here for future work!! Great honest mechanic. read more

I was having a problems with my starter and these guys are the best! They did not charge me to find out what the problems was. I was told by a pervious place that it was my alternator and starter. Once my car was inspected it was only a loose wire. This place is honest and won't screw you over. read more

I have a 2003 jeep that Mario has been working on, the first time i was sent there by my family i was very surprised with the honesty and good service i recieved! my entire family goes there, they don't trust their autos to anybody else! My ancle own a Jetta and Mario did an exellent job on the transmissions! So sorry to hear this Lady talking about they didn't know how to work on Jettas!!..we have nothing but good things to say about R&S Transmissions! Some people want all the repairs done for free and the will go to the extreme to get what they want! The service is great, the owner Mario and his wife are very nice people and overall...i will defenetly recomend this shop!! read more

This shop was recommended by a friend of mine. Although all the people who work there are friendly they did not do right by me. I took a Volkswagon Passat there and they clearly are not qualified to work on this type of car. They had my car on 5 separate times for a total of 2 1/2 months and still did not repair my car. I paid over $2,700. In the end, I had to take it to another shop to repair the mistakes they made and fix what they were unable to. This was a frustrating experience. I also filed a complaint with the "Better Business Bureau" and the "Bureau of Automotive Repair". I would think twice before you take your car to this shop. read more

I can't thank this company enough for the help they gave us on our Saturn. Mario is a professional, and he doesn't sugar coat a damned thing. He will tell you exactly how it is, and what needs to be done. It took us 8 months to get our stupid car smogged, and just when we gave up and were going to total it, we got a fix it ticket for the registration. The issues resounded with the fact the dealership had screwed up the pump, and since the car is discontinued, locating parts was a bitch. Mario laid it all out straight and gave us black and white instructions on the next step, including letting me know how I can order the parts and give them to him so it would be less expensive. Now she runs like a dream. I can't thank Mario and his family enough for all their help :) read more
