Disconnect the shift solenoid valves A and B connector. Measure shift solenoid valve A resistance between the No. 1 terminal of the shift solenoid valves A and B connector and body ground and measure shift solenoid valve B resistance between the No. 2 terminal and body ground. STANDARD: 12-25 ohm; Replace the shift solenoid valves A and B if either resistance is out of standard. If the resistance is within the standard, connect the No. 1 terminal of the shift solenoid valve A to the battery positive terminal. A clicking sound should be heard. Connect the No. 2 terminal to the battery positive terminal. A clicking sound should be heard. Replace the shift solenoid valves A and B if no clicking sound is heard when either terminal is connected to the battery terminal.

NOTE: Shift solenoid valves A and B must be removed/replaced as an assembly. Remove the harness clamp (C) form the clamp bracket (D). Remove the mounting bolts and the shift solenoid valves A and B. Clean the mounting surface and fluid passage. Install new shift solenoid valves A and B with a new filter/gasket (E) and install the harness clamp on the clamp bracket. Check the connector for rust, dirt, or oil, then reconnect the connector securely.
