Any time an electrical connector or solenoid body is disconnected, inspect the connector for pin condition, corrosion and contamination. Also inspect the connector seal for damage. Clean, repair or install a new connector as required.
Prior to carrying out the pinpoint tests, check the following
- Transmission fluid level.
- Transmission fluid condition (burned, metal particles or discolored).
- Engine cooling system.
- Other non-related transmission DTCs.
