Transmission & Clutch Repairin Ontario, CA.

Slipping under load (RPM rises but speed does not), a high or soft engagement point, chatter when pulling away, grinding when shifting, a burning smell, and a pedal that feels different than normal are common signs of a worn clutch.

Low or burnt fluid, worn clutch packs, failing solenoids, bad sensors, wiring problems or software faults can all cause slipping or harsh shifts. We scan the transmission controller and test the system to find the real cause before replacing parts.

Yes. We service manual, automated manual and automatic transmissions used in light, medium and heavy duty diesel trucks, including Eaton Fuller and Allison units.

We inspect the flywheel whenever the clutch is out. If it has heat checks, cracks or wear, we resurface or replace it so the new clutch engages smoothly and lasts.

It depends on the transmission, the fluid type and how the truck is used. Towing, heavy loads and stop and go work shorten the interval. We follow the manufacturer schedule and check fluid condition at every service.

It depends on the truck, the parts and what we find. We diagnose first, then explain the repair options and the price before any work begins, so there are no surprises. Call, text or use the form to get started.

Calling ahead is best so we can plan bay time and parts. If your truck is down, call (909) 701-8755 and we will tell you the fastest way to get it in.
