2. Check the resistance between contacts 1 and 2 of the connector.

- Standard resistance: 12-25 Δ
If the resistance is different from the above, replace shift solenoid valves A and B.
3. Apply battery voltage to the contacts of the solenoid valve connector (contact No.1 to "ground", contact No.2 to "+") and check by sound that the solenoid valve is working
If there is no actuation sound, replace the corresponding solenoid valve.
