Steps

How It Works

Driveline Assessment

We evaluate clutch function, fluid condition, and driveline components to determine the scope of service.

Diagnostics & Tear-Down

Fluid samples, pressure checks, and component inspections help us pinpoint failures before disassembly and repair.

Repair & Rebuild

We replace worn parts, reseal housings, resurface flywheels, and balance driveline assemblies to OEM spec.

Verification Road Test

The truck is road-tested under load to confirm smooth shifts, proper temperatures, and zero vibration before delivery.

Questions

Frequently Asked Questions

What are signs of transmission problems?

Common warning signs include slipping gears, grinding or difficulty shifting, delayed engagement when putting the truck in gear, unusual noises during acceleration, fluid leaks under the truck, and the check engine light coming on. If you notice any of these symptoms, have your transmission inspected before the problem worsens.

Do you service Allison transmissions?

Yes, we service Allison automatic transmissions including fluid changes, filter replacements, shift calibrations, and repairs. Our technicians are experienced with the full range of Allison models used in medium and heavy-duty trucks.

How often should transmission fluid be changed?

Most manufacturers recommend transmission fluid changes every 30,000-60,000 miles, but this varies based on operating conditions. Trucks used for heavy hauling, frequent stop-and-go, or extreme temperatures may need more frequent service. We can analyze your fluid and recommend the right interval for your application.

Can you repair Volvo I-Shift transmissions?

Yes, we specialize in Volvo I-Shift service and repair. This includes clutch replacement, actuator service, software updates, and diagnostics. Our technicians have specific training on I-Shift automated manual transmissions and use proper Volvo diagnostic tools for accurate troubleshooting.
