Transmission Drive Cycle Test: Notes

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. Transmission failure must occur 4 times consecutively for shift error DTC to be set and 5 times consecutively for continuous Torque Converter Clutch (TCC) DTCs to set.

NOTE: When carrying out the Transmission Drive Cycle Test, use the Solenoid Operation Chart for proper solenoid operation. Refer to Pinpoint Tests - OSC Equipped Vehicle .

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

Record and then clear Self Test codes.
Warm engine to normal operating temperature.
Make sure transmission fluid level is correct.
With the selector lever in Overdrive (Circle D) position, moderately accelerate from stop to 80 km/h (50 mph). This allows the transmission to shift into 5th gear. Hold speed and throttle open steady for a minimum of 15 seconds.
With transmission in 5th gear and maintaining steady speed and throttle opening, lightly apply and release the brake to operate the stop lamps. Then hold speed and throttle steady for a minimum of 5 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 Self Test and record continuous DTCs.
