Detroit Built Is Different

Pat and Dan at Grandma’s Speed Shop have built theIr reputations on hard work, honesty and a commitment to quality. With the services and expertise here, there’s no job too big or too small. Because when it comes to any diesel job, it’s a job worth doing right.

Fleet Repair & Maintenance

Your business is our business. We keep your fleet on the road moving and earning. Minimize your downtime. Keep your team safe behind the wheel. Go with a diesel performance partner you can trust. Get to Grandma’s.

General Repair

Fluid and oil changes don’t have to be done in your garage or driveway. Save the time for something else. Let the guys at Grandma’s take care of all your diesel repair and maintenance needs—fender to fender.


Bring it in with a grind, whine, or whistle, and we’ll get to the bottom of it with the latest in diagnostic and coding software. Whatever has your ride down, bring it in. We’ll hook it up, and quickly get you out.
