SPECIAL TOOLS CHART

Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool

NOTE: If equipped, turn the Power Take-Off (PTO) unit off for correct test results. For a description of PTO operation, refer to TRANSMISSION ELECTRONIC CONTROL SYSTEM .

NOTE: Always drive the vehicle in a safe manner according to driving conditions and obey all traffic laws.

NOTE: Follow the Transmission Drive Cycle Test exactly. Malfunctions must occur 4 times consecutively for the shift error DTC to set. Torque converter failures must occur 5 times consecutively for a continuous DTC to set.

NOTE: When carrying out the Transmission Drive Cycle Test, refer to the Solenoid Operation Chart for correct solenoid operation.

After carrying out the self-test, use the Transmission Drive Cycle Test for checking continuous codes.

Record and then clear the self-test DTCs.
Warm the engine to normal operating temperature.
Make sure the transmission fluid level is correct.
With the selector lever in (D), moderately accelerate from stop to 80 km/h (50 mph). This allows the transmission to shift into 6th gear. Hold the vehicle speed and throttle position steady for a minimum of 15 seconds.

Brake to a stop and remain stopped for a minimum of 20 seconds.
Repeat Steps 4 through 6 at least 5 times.
Carry out the self-test and record the continuous codes.
