J 21867 Pressure Gage
For equivalent regional tools, refer to Special Tools.
Warning: Keep the brakes applied at all times in order to prevent unexpected vehicle motion. Personal injury may result if the vehicle moves unexpectedly.
Note: You may need to remove or disconnect components in order to gain access to the transmission line pressure test hole plug.
Note: In order to achieve accurate line pressure readings, the following procedure should be performed at least three times.
The values displayed on the scan tool screen will not match the actual pressures indicated on the pressure gage. Control the Line PC Solenoid in PARK or NEUTRAL with the engine speed at approximately 1500 RPM and the TFT between 35-55°C (95-131°F). This protects the clutches from extreme high or low line pressures and ensures a consistent pump capacity.Caution: Refer to Fastener Caution in the Preface section.
