Shift Solenoid Leak Test

Shift solenoids 1, 3, and 5 produce audible clicks when they are opened and/or closed. Shift solenoids 2 and 4 may not produce any audible sound. Do not assume that shift solenoids 2 and 4 are inoperable if they do not click. If the vehicle has the symptoms of a stuck solenoid on the symptom chart, use the following procedure to determine if a shift solenoid is inoperable.
1. Command each shift solenoid On and Off with a Scan tool.
2. Listen for audible clicks from the solenoids. The use of chassis ears or a stethoscope will aid in this step.
3. Compare the results of the click test with the chart.
4. If any shift solenoid does not click as expected, there may be an electrical condition, or the solenoid may be stuck.

Use the following procedure to isolate an electrical condition for a shift solenoid.
1. Disconnect the transaxle harness connector.
2. Connect a test light to the shift solenoid control circuit in the harness connector, and a good ground.
3. Command the shift solenoid On and Off.
4. If the test light does not turn On and Off, the circuit may be open, or the TCM may be inoperable.
5. Connect the J-45188 jumper harness to the transaxle.
6. Measure the resistance of each shift solenoid.




7. Compare the resistance of each shift solenoid with the temperature/resistance chart.
8. If the resistance of any shift solenoid is not within the specification, check the internal harness for an open or high resistance. If Ok, replace the shift solenoid.

Use the following procedure to determine if a shift solenoid is stuck.

1. Remove the shift solenoid.

NOTE: Do not leave 12v connected to the shift solenoid for more than 10 seconds continuously. Leaving 12v connected for too long will cause the solenoid to overheat.




2. Repeatedly connect and disconnect 12v to the shift solenoid.
3. Observe the shift solenoid pintle.
4. If the shift solenoid pintle does not move, replace the shift solenoid.
