Transmission Output Shaft Bearing Noise Detected
on 2011 GMC Terrain 2.4L I4 · FWD
What this code means
The TCM or vibration sensor has detected a signature consistent with output shaft bearing wear in the transmission.
Symptoms
- Whining noise proportional to vehicle speed
- Noise changes with load but not with gear
- Vibration felt through floor
- Noise present in all gears
- Transmission fluid may have metallic sheen
Common causes
- Output shaft bearing wear
- Insufficient lubrication
- Bearing preload incorrect
- High mileage wear
- Contaminated fluid causing bearing damage
Diagnostic steps
- Listen for bearing noise at varying speeds
- Check transmission fluid for metal particles
- Perform vibration analysis
- Road test in multiple gears to isolate source
- Inspect transmission for external leaks
Repair notes
Transmission removal and bearing replacement required. Inspect output shaft for scoring. Replace fluid and filter.
