Common GM Transmission Problems
GM transmissions are solid, but like anything mechanical, they have known failure points—especially under load or higher mileage.
We regularly diagnose and repair:
- Slipping gears
- Hard or delayed shifting
- Transmission not going into gear
- Torque converter issues
- Valve body problems
- Transmission fluid leaks
- Check engine light related to transmission performance
Getting ahead of these issues early can prevent a full failure.

Rear-Wheel Drive & 4WD Specialists
We focus on front-engine, rear-wheel drive and 4WD GM vehicles, which means trucks and SUVs are a big part of what we do.
That includes:
