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 in this article.

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

NOTE: The Transmission Drive Cycle Test must be followed exactly. Malfunctions must occur 4 times consecutively for the shift error DTC to be set. Torque converter clutch (TCC) failures must occur 5 times consecutively for a continuous TCC DTC code to be set.

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

After carrying out the Quick Test, use the Transmission Drive Cycle Test for checking continuous codes.

Record and then erase the Quick Test codes.
Warm the engine to normal operating temperature.
Make sure the transmission fluid level is correct.
With the transmission range selector lever in Overdrive (Circle 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.
With the transmission in 6th gear and a steady vehicle speed and throttle position, lightly apply and release the brake pedal enough to operate the stop lamps. 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 Quick Test and record continuous codes.
