Valve Body: Testing and Inspection

OVERDRIVE (OD) SOLENOID CHECK
1. Disconnect the solenoid & pressure switch assembly connector.
2. Measure the resistance between the solenoid & pressure switch assembly side connector terminals 6 and 8.

Standard value: Approximately 1 ohm [at 200°C (680°F)]

3. If the resistance is outside the standard value, replace the solenoid & pressure switch assembly.





LOW/REVERSE (LR) SOLENOID CHECK
1. Disconnect the solenoid & pressure switch assembly connector.
2. Measure the resistance between the solenoid & pressure switch assembly side connector terminals 4 and 6.

Standard value: Approximately 1 ohm [at 200°C (680°F)]

3. If the resistance is outside the standard value, replace the solenoid & pressure switch assembly





2/4 SOLENOID CHECK
1. Disconnect the solenoid & pressure switch assembly connector.
2. Measure the resistance between the solenoid & pressure switch assembly side connector terminals 3 and 6.

Standard value: Approximately 1 ohm [at 200°C (680°F)]

3. If the resistance is outside the standard value, replace the solenoid & pressure switch assembly.





UNDERDRIVE (UD) SOLENOID CHECK
1. Disconnect the solenoid & pressure switch assembly connector.
2. Measure the resistance between the solenoid & pressure switch assembly side connector terminals 6 and 7.

Standard value: Approximately 1 ohm [at 200°C (680°F)]

3. If the resistance is outside the standard value, replace the solenoid & pressure switch assembly.
