The P0767 code in your 2020 Chrysler Pacifica indicates shift solenoid D is stuck in the engaged (on) position within the 9HP 9-speed automatic transmission. This condition prevents normal gear progression as one clutch pack remains constantly engaged.
Pacifica's ZF 9HP Transmission
The Chrysler Pacifica uses the ZF 9HP automatic transmission, known for smooth operation in minivan applications. Shift solenoid D controls specific gear engagement sequences. When stuck on, the transmission cannot release that clutch for normal shifting.
What Causes Solenoid D Stuck On
- Internal solenoid mechanical failure
- Electrical short keeping solenoid energized
- Valve body contamination
- Debris in solenoid plunger
- TCM continuously commanding solenoid
- Mechatronic internal fault
Symptoms of P0767
- Harsh or clunking shifts
- Transmission stuck in gear
- Check engine light on
- Limp mode activation
- Reduced power or acceleration
- Unusual transmission noises
Family Vehicle Considerations
As a family hauler, the Pacifica's transmission reliability is important for safety and convenience. Prompt diagnosis of P0767 prevents being stranded and protects your passengers from unexpected transmission behavior.
