Maintain It. Or Rebuild It.

Some transmission problems can be fixed with proper service and early repairs. Others are caused by internal wear that requires a rebuild or replacement. We look at the condition honestly and tell you which option makes sense before work begins. For diesel truck transmission work, see our diesel transmission service page.

Common Questions

How do I know if my transmission needs service or repair?
Hard shifting, slipping, delayed engagement, warning lights, burnt fluid smell, or transmission leaks are common signs that service or repair is needed. Bring it in and we will scan the TCM, check the fluid, and road test before telling you what it actually needs.
Do you repair both automatic and manual transmissions?
Yes. We repair and rebuild automatic transmissions, manual transmissions, transfer cases, and clutch systems for passenger vehicles and work trucks.
Can transmission fluid service fix shifting problems?
In some cases yes. If internal damage has not occurred, a fluid service and shift relearn procedure can improve shift quality. We check the fluid condition first and tell you honestly whether a service will help or whether the problem is internal.
Do you diagnose transmission control module problems?
Yes. We perform transmission diagnostics including TCM scanning, live data analysis, electrical testing, and shift adaptation procedures.
Do you use OEM transmission parts?
We use OEM parts whenever available and high-quality replacement components when OEM parts are not. The quote shows exactly what is going in before work starts.
Do you work on diesel truck transmissions?
Yes. For heavy-duty diesel truck transmission work, see our dedicated diesel transmission service page.
