- 3-4 shift solenoid control circuit open
- Fused B+ circuit open
- Transmission control relay output circuit open
- 3-4 shift solenoid control circuit short to ground
- Transmission relay output circuit short to ground
- 3-4 shift solenoid control circuit short to voltage
- 3-4 shift solenoid control circuit short to other circuits
- 3-4 shift solenoid
- Transmission control relay - poor contacts
- Powertrain control module
- Intermittent wiring and connectors
