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 a shift error DTC to set, and 5 times consecutively for continuous Torque Converter Clutch (TCC) DTCs to set.
NOTE: Refer to the Solenoid Application Chart for solenoid operation while performing the Transmission Drive Cycle Test.

After performing the self-test, follow the transmission drive cycle test for checking codes.

  1. 1.

    Record then clear the DTCs.

  1. 2.

    Warm the engine to normal operating temperature.

  1. 3.

    Make sure the transmission fluid level is correct.

  1. 4.

    With the selector lever in Overdrive (O/D), moderately accelerate from stop to 80 km/h (50 mph) allowing the transmission to shift into 6th gear. Keep vehicle speed and throttle steady for a minimum of 15 seconds.

  1. 5.

    With the transmission in 6th gear and maintaining steady speed and throttle, lightly apply and release the brake pedal to operate the stop lamps. Then, hold vehicle speed and throttle steady for a minimum of 5 seconds.

  1. 6.

    Brake to a stop and remain stopped for a minimum of 20 seconds.

  1. 7.

    Repeat steps  4 through  6 at least 5 times.

  1. 8.

    Perform a self-test and record DTCs.
    • If DTCs are present, refer to the DTC Chart in Diagnostic Trouble Code (DTC) Charts . Repair all non-transmission DTCs first as they can directly affect the operation of the transmission. Repeat the self-test and the road test to verify the correction. Clear the DTCs. Perform the transmission drive cycle test and repeat the self-test after completing the repair.
    • If the tests pass and a concern is present, refer to Diagnosis By Symptom , OASIS messages and TSBs for concerns.
