At Gilmore's Auto Service in Walnut Creek we diagnose and repair GMC cars, trucks, and SUVs with precision. GMC is an offering from General Motors that blends performance and reliability into an affordable package. For many fleet owners their GMC trucks are important and reliable assets that allow them to get tough jobs done every day.
The GM family of vehicles often share parts with other GM brand vehicles, which means GMC vehicles can suffer from similar problems. Transmission, towing and drivetrain issues can arise without proper preventative maintenance. Regular oil changes and maintenance can greatly reduce high-cost auto repairs down the road.

OUR REVIEWS
Valeriya Brauer, 01/30/2026Last month I was in the area with a couple of my kiddos when my car started acting up. I was too far from my usual mechanic and started getting quite concerned as the car was telling me to shut it off. I called around 7-8 auto shops and received the same answer 'too busy', 'almost closing time' etc. I finally got a hold of the guys at Gilmore and they were able to see me right away, even if they were closing soon. They found the issue, fixed it quickly, and checked on me after ward to make sure I made it home safe. If that's not service, I don't know what is. Go see the workers at Gilmore. They'll take good care of you.
