- Shift control solenoid valves are located on lower valve body assembly. See Figure . Blue wire is for shift control solenoid valve "A" and Green wire is for solenoid valve "B".
- Disconnect transaxle sub-harness connector. See Figure . Using ohmmeter, measure resistance between ground and shift control solenoid terminals No. 4 (Green/White wire) and No. 5 (Blue/Yellow wire). Resistance should be 12-25 ohms. If resistance is not as specified, go to next step. If resistance is as specified, go to step 4 .
- Remove shift cable cover. Disconnect shift control solenoid valve harness connector from transaxle sub-harness at the transaxle. Measure resistance between ground and solenoid harness connector terminal No. 1 (Green wire) and terminal No. 2 (Blue wire). See Figure . If resistance is as specified, go to next step. If resistance is not as specified, replace shift control solenoid valve.
- Check shift control solenoid valve operation. Ensure shift control solenoid valve body is grounded. Apply battery voltage to solenoid terminal No. 2 (Blue wire) and then to solenoid terminal No. 1 (Green wire). See Figure . Clicking sound should be heard when voltage is applied. If clicking sound is not heard, replace shift control solenoid valve assembly. If clicking sound is heard, replace transaxle sub-harness connector assembly.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
