- 3-4 solenoid wiring harness intermittent def
- 3-4 solenoid wiring harness observably def
- Shift solenoid control circuit short to ground
- Solenoid and harness def (solenoid control ckt)
- Solenoid and harness def (Solenoid pack conn)
- Trans relay output circuit open
- Trans relay output circuit shorted to ground
- PCM defective (3-4 sol cntl ckt)
- PCM defective (code set)
