Shift Solenoid: Testing and Inspection

NOTE: Shift control solenoid valves A and B must be removed/replaced as an assembly.

1. Disconnect 3P connector from the shift control solenoid valve A/B assembly.




2. Measure the resistance between the No. 1 terminal (solenoid valve A) of the shift control solenoid valve connector and body ground, and between the No. 3 terminal (solenoid valve B) and body ground.

STANDARD: 14 - 25 ohms

3. Replace the shift control solenoid valve assembly if the resistance is out of specification.
4. If the resistance is within the standard, connect the No. 1 terminal of the shift control solenoid valve connector to the battery positive terminal. A clicking sound should be heard. Connect the No. 3 terminal to the battery positive terminal. A clicking sound should be heard. Replace the shift control solenoid valve assembly if no clicking sound is heard.
