Our story
Straight talk from Ernesto and the crew
A-1 Auto Repair & Transmission is a Hayward shop built around transmissions and driveline work. Ernesto leads the crew, working alongside Luis to figure out everything from a truck shaking at a stoplight to a transmission that needs a full rebuild.
We've rebuilt transmissions in everything from a 1998 Corvette to a 2007 Ford Ranger, replaced rear axles, fixed drive shaft u-joints, and swapped out fuel injectors, always walking you through what's actually wrong before we start the work.
When we quote a job, that's the number you pay when it's done. No surprise add-ons at pickup, just the repair we said we'd do for the price we said it would cost.

What customers say
“Ernesto did a fantastic job on my truck. He fixed the U-joints of the drive shaft within hours of me bringing him the problem. My truck sounds so much better now! He diagnosed the problem quickly and was very fair and knowledgeable. Highly reccomend A-1 Auto!”
“98 corvette, transmission was rebuilt and rear axles replaced. Earnesto and his guys did a great job and quick. The transmission feels good no hard shifting and no slipping and no leaks! I definitely recommend these guys, very happy with the work they did.”
“If your looking for great, reliable, and honest mechanics, A-1 Auto in Hayward is the place to go! Ernesto, Luis and the team are great. My truck was shaking at every stop light and they were able run a diagnostics, explain what was going on with it (in an easy to understand way) and gave me options on what could be done to fix it. A new set of fuel injectors later I was back on the road.”
