Very pleased with service performed on my vehicle and Alex's customer service. SUV runs a lot smoother. No clunks, problem was fixed in timely manner and reasonably priced, 1/2 the cost of dealership services! Will be a returning customer if issues arise with my vehicle. I highly recommend A 1 Transmission in Antioch. Satisfied customer.

⭐⭐⭐⭐⭐

Everybody go to Alex! Not only did he have the lowest price for a transmission rebuild for my Ford Ranger out of the 6 shops I called, but he went above and beyond inspecting the truck and taking care of it like it was his own. Very pleased and will be doing more business with A-1 Transmission Antioch as well as referring friends and family to this shop.
