J 45195 Pressure Gage
Caution: Keep the brakes applied at all times in order to prevent unexpected vehicle motion. Personal injury may result if the vehicle moves unexpectedly.
Important: Permatex High Temperature Threadsealant P/N 21485278 (GM P/N 12346004) or equivalent must be applied to the threaded components of the pressure gage to ensure that no leakage occurs during testing.
Notice: The total test running time should not be longer than 2 minutes. Running the test longer than 2 minutes may damage the transaxle.
Important: The scan tool can only control the line pressure control solenoid when the transaxle is in PARK and the engine is running. This protects the transaxle clutches from extremely high or low pressure, as occurs when the transaxle is in DRIVE or REVERSE.
Important: In order to obtain the required pressure for the high pressure test point, the engine speed must be 1,400-1,500 RPM. A line pressure reading taken at a lower engine speed will be inaccurate and may lead to misdiagnosis.
Important: Before installing the fluid pressure test hole plug, apply Permatex Medium Grade Threadlocker Blue P/N 12345382 or equivalent to the threads of the plug.
Tighten
Tighten the plug to 9 N·m (7 lb ft).
