- Delayed engagement
- Transmission overheating
Common causes
- Faulty pressure control solenoid
- Low transmission fluid level
- Damaged solenoid wiring or connector
- Faulty transmission control module
Diagnostic steps
- Scan for stored transmission codes
- Check transmission fluid level and condition
- Inspect solenoid circuit wiring
- Test solenoid resistance and command operation
