We rebuild the part
other shops replace.
A family-run transmission and auto shop on Baldwin Park Blvd since the 90s. Automatic and CVT rebuilds, honest diagnosis, and a one-year warranty on the work. Don Jorge and the crew have kept this neighborhood driving for over 25 years.
Transmissions are our thing
Most shops send transmission work out or just swap the whole unit. We do the rebuilds ourselves, which is how we keep the quality high and the price fair.
Automatic Rebuilds
Full automatic transmission rebuilds done in-house. We tear it down, replace what's worn, and put it back together so it shifts like it should.
CVT Repair & Rebuild
Rough shifting, stalling at stops, running rough on the freeway. We rebuild CVTs properly instead of just throwing parts at the problem.
Reman & Replacement
When a rebuild isn't the right call, we fit a quality remanufactured unit and stand behind it. You get the honest recommendation either way.
Transmission Diagnostics
Not sure if it's the transmission at all? We diagnose it first and tell you straight, so you're not paying to fix the wrong thing.
General Auto Repair
We're a full-service shop too. Brakes, engine work, and regular maintenance, all with the same honest pricing our regulars have counted on for years.
Certified Welding
Certified welding on premises for the jobs other shops send out. It stays here, it gets done right, and it gets done faster.

A 1965 Mustang, back on the road in three days.
One customer brought in his classic Mustang for a full transmission rebuild. We had it running like new inside three days, backed by our one-year warranty. Daily driver or a car you've loved for decades, it gets the same care.

Run by Don Jorge, trusted since the 90s
A Transmission has been on Baldwin Park Blvd for more than 25 years, and a lot of our customers are the kids of customers we had back then. Owner Jorge Lopez still runs the front and the floor, and he's DENSO First Time Fit certified, including hybrid vehicle service.
What keeps people coming back is simple: we tell you what's actually wrong, we quote it honestly, and more than once we've charged less than the estimate because the part came in cheaper. No pressure, no upsell, just work you can trust.

Straight from the shop's Google reviews. Real customers, real cars.
I'm really happy with this place, they rebuilt my 1965 Mustang transmission and it's now working like new. Very responsive team and job well done. They did it within 3 days, super fast, plus a 1 year warranty. I own 7 cars and they just got a new customer. Thank you guys.
I brought in my 2013 Nissan Rogue for its CVT transmission. Before, it was shifting very rough, shutting off at stops, and running rough while driving. They offered a rebuild or a remanufactured replacement. I opted for the rebuild and the quality has been excellent. It drives extremely smooth now. Thank you Jorge and team.
The first time I went to Jose, it was for a full service. He gave me a price, and when it came time to pay, he told me it was actually less than the original quote because the part cost less. Honestly, he is a very honest person, professional, quick, and the customer service was excellent. I 100% recommend this place.
My family and I have been coming to Don Jorge since the 90s and he's still our go-to, reliable mechanic. Highly recommend his shop.
