two racecars on a track

JASPER Engines and Transmissions is pleased to announce that the JASPER 4-Speed Transmission is being used by 28 team/driver combinations in the 2022 NASCAR Xfinity Series season.

This is an exciting leap as the same transmission was used by 12 team/driver combinations in the series in 2021. These team/driver combinations accounted for 19 wins, 84 top-five finishes, and 147 top-ten finishes for the 2021 season.

Ecstatic - called on a Friday to see if they could work on my car. I was having issues with rough idling and several sensors coming on and off, and also needed to see if it was time for a check up. Told to bring my car in early Saturday (yes on the weekend) and they would look at it. Come to find out all I needed was an oil change. When I picked up my car, they explained everything that I asked about, and let me know that my next large service wasn't for 15k miles, and gave me an roundabout figure of what that would cost. So happy to find a honest mechanic, will definitely be returning for this service and all others needed to keep my car running. Thank you, for being you.

Wayne is the best in the business. Our family has used Wayne on new cars and our classic 66 Lincoln Continental Convertible. If you want someone who can fix anything Wayne is the guy. Mechanics always get a bad rep because it's full of people claiming to be mechanics, however, a true mechanic is rare. Wayne is the real deal.

A+++ Best auto shop you will find! I had a problem, called these guys and they got me right in and found the problem within 5 minutes of being at the shop and had the part 20 minutes later and my car was done 20 minutes after that. Ever other shop takes days to even get around to looking for the problem! This is my new shop for any auto needs. Great staff too. The car is completely fixed.
