- Perform the Shift Solenoid Leak Test
.
- If the solenoid fails the shift solenoid leak test, replace the affected solenoid.
- Disconnect the wiring harness connector from the affected solenoid. Measure the resistance for the affected solenoid. The resistance should be between 19 and 31 ohms for the 1-2 SS and the 2-3 SS. The resistance should be between 10 and 15 ohms for the TCC PWM solenoid.
- If the resistance is not within the specified range, replace the affected solenoid.
