Common Allison Truck Transmission Repairs Done in Denver

Gear Slipping and Rough Shifting

If your truck hesitates to shift or jumps between gears, it may indicate worn clutch packs, a failing solenoid, or dirty transmission fluid. Our team performs complete system diagnostics to isolate the cause and replaces worn-out parts for lasting results.

Transmission Overheating

Allison transmissions are often used in high-torque applications. Thus, making them prone to overheating when fluid levels drop or cooling systems fail. Overheating can degrade fluid, warp internal parts, and damage seals. We install upgraded coolers and flush contaminated fluid.

Fluid Leaks

Leaking fluid under your truck points to cracked pans, worn gaskets, or broken seals. If left unaddressed, this can lead to overheating and failure. Our technicians locate the source of the leak quickly and reseal or replace affected parts. We also top off and test the fluid to ensure its quality.

Electronic Control Module Failures

Allison transmissions rely on the Transmission Control Module (TCM) to execute shift timing and pressure adjustments. When this module malfunctions, you may see dashboard warning lights or erratic shifts. We use specific diagnostic software to identify and reprogram / replace faulty TCMs.

Torque Converter Problems

A failing torque converter can cause shuddering, poor acceleration, or unusual noises. This component is important for transferring engine power into the transmission. We evaluate torque converter performance through load testing and vibration analysis, then repair or replace it.
