NOTE:
The Transmission Drive Cycle Test must be followed exactly. Malfunctions must occur 4 times consecutively for shift error DTC to be set, and 5 times consecutively for continuous Torque Converter Clutch (TCC) code to set.
NOTE:
Refer to the SOLENOID OPERATION CHART for correct solenoid operation when performing the Transmission Drive Cycle Test.
Use the Transmission Drive Cycle Test for checking codes after performing a self-test.
- Record then clear the DTCs.
- Warm 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) allowing the transmission to shift into 6th gear. Keep vehicle speed and throttle steady for a minimum of 15 seconds.
- With the transmission in 6th gear and maintaining steady speed and throttle, lightly apply and release the brake to operate 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 five times.
- Perform a self-test and record DTCs.
- If DTCs are present, refer to the DTC CHART . Repair all non-transmission DTCs first as they can directly affect the operation of the transmission. Repeat the self-test and road test the vehicle to verify the repair. Clear the DTCs. Perform the drive cycle test and repeat the self-test after completing the repair.
- If the tests pass and a concern is still present, refer to DIAGNOSIS BY SYMPTOM , OASIS messages and TSBs regarding concern.
