8. Measure the shift solenoid valve resistance between the shift solenoid harness

connector terminals below and body ground:

No. 1: Shift solenoid valve C

No. 2: Shift solenoid valve B

No. 5: Shift solenoid valve A

No. 8: Shift solenoid valve D

Standard: 12-25 ohms

If the resistance is within the standard, go to step 9 and check solenoid
valve for a clicking sound.

If the resistance is out of standard, go to step 10.

9. Connect a jumper wire from the battery positive terminal to each shift solenoid

harness connector terminals individually. A clicking sound should be heard.

If a clicking sound is heard, the valves are OK.

The test is complete, connect the connector.

If no clicking sound is heard, go to step 10 and test the shift solenoid
harness.

11. Reinstall the drain plug with a new sealing washer (B).
12. Remove the shift solenoid valve cover (A), the dowel pins (B), the gasket (C),

and the harness clamp bracket (D).

14. Measure the resistance of each solenoid valve between the connector terminal

and body ground.

Standard: 12-25 ohms

If the resistance is out of standard, go to step 17 and replace the shift
solenoid valve.

If the resistance is within the standard, go to step 15 and check the
solenoid valve for a clicking sound.

15. Connect a jumper wire from the positive battery terminal to each solenoid

terminal individually.

If a clicking sound is heard, go to step 16 and replace the solenoid harness.

If no clicking sound is heard, go to step 17 and replace shift solenoid
valve.

16. Remove the shift solenoid harness connector (A), and replace it. Install a new

O-ring (B) on the shift solenoid harness connector, and install the connector in
the transmission housing, then go to step 22.

17. Remove the mounting bolts, then hold the shift solenoid valve body and

remove the solenoid valves. Do not hold the connector to remove the solenoid
valve.
