Compatible across GM models from 2006-2014, including Chevrolet Impala, HHR, and Pontiac G6, it restores reliable performance without dealership visits.
Common Issues & How This Fixes Them
Over the years, I’ve pinpointed TCM failures in Cobalts to factors like voltage spikes or internal circuit degradation, especially in high-mileage cars around 100,000 miles. Stats from my shop show about 40% of these stem from overheating during stop-and-go traffic, leading to costly transmission wear if ignored.
- Harsh shifting or delays: The new TCM recalibrates solenoid timing, smoothing transitions and preventing slippage.

- Intermittent failures: Built-in redundancies handle electrical glitches, avoiding complete breakdowns.
