Stuck In Gear - Not Specified
The TCM detects that the transmission is stuck in some gear but cannot identify which one — typically because multiple input/output ratio cross-checks fail simultaneously, or an early-detection diagnostic fires before the specific-gear detection runs.
Affected components
- Shift solenoids
- Clutch pack
Common causes
- High likelihood: Multiple solenoid or clutch failures
Possible symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
Diagnostic notes
- The malfunction indicator lamp may illuminate
