What People Say
“Mario and his crew are the best. Honest, fair, and they actually fix the problem. I had my transmission rebuilt here and it's been running perfectly for over a year. Highly recommend.”
San Diego Customer
via Yelp“Took my truck here after another shop gave me a crazy quote. M&R diagnosed it for much less and fixed the real problem. These guys are trustworthy — rare in auto repair.”

It depends on the condition of your transmission and the vehicle. In many cases, a professional rebuild is far more cost-effective than replacement. We'll give you an honest recommendation after inspecting your vehicle.
