I highly recommend Ralph's to solve your transmission service needs. My van drives better than ever. Ralph's Transmission gave me the best possible attention and service money can buy. My transmission burned up driving up a mountain. Three other mechanics wouldn't touch my transmission. I believe that transmission building and repair is the brain surgery of the automotive world. This might sound hard to believe but I had my van towed 100 miles just so Ralph's could handle the repair. Ralph's backs their transmission with a 3-year warranty, which made me feel a lot better. I asked them a lot of questions. A LOT! This was .a huge investment for me, and I only want to do it ONCE. Since I depend on my vehicle for my business, I needed a compete and lasting solution. If I was to spend the money to repair it, I needed it done right and I needed a SUPER-DUTY transmission. Mario and the entire staff explained in detail what I needed to properly repair my transmission. They were even able to diagnose the cause of the failure. They completely rebuilt my transmission instead of slapping Band-Aid on the problem. They communicated with me about the type of parts going into my transmission and they guided me into making decisions about using heavy-duty parts. I'll update my post with anything new. Bonus: The Taco truck at Ralph's makes delicious food.

THANKS RALPH'S You have a great staff..!

I live by Sea World in San Diego. I drove over 450 miles to get my truck RALPH'S Transmission. The girls up front are friendly and professional. AFTER a BAD experience with a transmission shop in San Diego, I decided I would drive my 97 F20 4x4 to Modesto with its missing 2nd gear. I-5/99 all the way and really no trouble to get a better transmission REBUILD and a great warranty. I have told my friends in San Diego if they need a transmission Ralph's is the place to go. The truck was done in 4 days. I couldn't return for almost another week to get my truck. That was no problem for them. Thank you Mario for having a great business in Modesto. Maybe you could open a second shop in San Diego? Great weather year-round, with the ocean/beaches nearby and Disneyland only a couple hours (if riding AMTRAK) or less from here depending on traffic. I will take any vehicle to RALPH'S from transmission work in the future. I was definitely worth paying a few dollars more for a much more professional experience!

Defective Input drum. This is a Part they installed and it was complete crap.

See all

OCTOBER 19, 2025 UPDATE After all of my phone calls to him…read morefor car advice and no matter how annoying I can be, Frank has never once lost his patience with me. Frank holds high standards of service, knowledge and hard work and he insists on the same for his employees. His prices are fair, he's honest and his education is extremely impressive. After I totaled my car frank helped me choose one without hesitation (probably because I kept bringing my choices to him only to have him say NO YO ). After more than a decade of trusting my car and safety with Gateway and thanks to Franks help ... I finally purchased a new car and it Looks like I'll be a loyal customer forEVER The shop is open Mon thru Fri and his prices remain very fair. END UPDATE For years I have been able to rely on and trust the staff of Gateway Automotive. Today when my car died outside of the library I called the shop and Ryan assured me that if I towed it over they would take care of it so I did. I was immediately greeted by the staff and Ryan went straight to work. The problem was diagnosed and repaired in less than 2 hours. He was direct, accurate and incredibly helpful. I am grateful for his hard work. The entire staff is friendly, knowledgeable and professional. I ALWAYS recommend this shop for the fact that they've never been wrong and have always been honest. Many times I've sent my friends to Gateway for second opinions and nearly every time their diagnosis was on point and way more affordable. It's hard to find an honest mechanic in this town... Gateway fills that need

I have a lot of empathy for the young guys working at this facility. Unfortunately, I was there…read moreuntil 6 PM because somebody quit and my car was pushed to the end of the line even though I arrived at 7:45 AM. Why is the owner not supervising these young technicians? They have very little experience and should be supervised by experienced in licensed mechanics. When I picked up my vehicle, the alignment seemed way off. I'm not sure if it has anything to do with the work they performed, but they certainly took the two front rims and tires off the vehicle. All I can tell you is my steering wheel was jiggly back & forth driving over 60mph. As a result, I have to take my suv to a tire shop for a wheel alignment. Another $100 bucks.
