Circuit/System Verification
1. Engine ON, verify the transmission fluid temperature is between 50-80掳C (122-176掳F).
2. Operate the vehicle long enough to verify at least a 3掳C (5掳F) rise in TCM temperature parameter, then operate the vehicle in Park for 5
seconds.
3. Engine ON, observe the scan tool Line PC Sol. CKT Status parameter. The reading should display OK or Indeterminate.
瀚慖f the reading is not within the specified range, replace the control solenoid valve assembly.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

Ignition ON, observe the scan tool Trans. Fluid Temp. and the TCM temperature parameters. The readings should vary less than 10掳C (18掳F).
If within the specified range, test for a transmission overheat condition.
If greater than the specified range, replace the Q8 control solenoid valve assembly.
Component Testing
* Perform the Fluid Leak Diagnosis (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component
Tests and General Diagnostics/2ML70 - Automatic Transmission/Fluid Leak Diagnosis).

Inspection/Symptom Related Diagnostic Procedures/2ML70 - Automatic Transmission/Main Fluid Pump Pressure High or Low) procedure.
* With a hand held infra red thermometer, or J 24731 test for the transmission cooler supply line thermostat for opening at 80掳C (176掳F). The
transmission cooler supply line temperature should be higher on the transmission side of the thermostat than the cooler side until 80掳C (176掳
F) is reached.
瀚慖f the thermostat tests stuck open or closed, replace the transmission cooler supply pipe assembly.
