Double Flush Repair Procedure

The double flush ensures a more comprehensive replacement of contaminated fluid than a single flush by circulating residual fluid from the torque converter not removed in the initial flush.

1. Raise the vehicle on an appropriate hoist.

2. Remove the oil pan and drain the ATF.

3. Install the transmission oil pan.

4. Lower the vehicle leaving the rear wheels off the ground.

5. Fill the transmission with MS-9602 ATF+4 (approximately 3 - 4 qts).

6. Start the engine.

7. Shift the transmission into drive and lightly accelerate the engine speed to allow the transmission to upshift through gears.

8. Apply the brakes and stop the wheels from turning.

9. Shift the transmission into reverse and release the brakes. Let the wheels turn for approximately 5 seconds.

10. Apply the brakes and stop the wheels from turning.

11. Repeat steps 7 - 10 two more times and turn off the engine and place the transmission in park.

12. Stop the engine.

13. Raise the vehicle.

14. Remove the transmission oil pan and drain the ATF.

15. Clean the transmission and oil pan mating surfaces.

16. Apply ATF-RTV, p/n 05010884AA to the transmission oil pan sealing flange.

17. Install the transmission oil pan. Torque the fasteners to 20 Nm (175 in. lbs.).

18. **Remove the dipstick tube cap**.

19. **Remove the bolt holding the transmission fill tube to the transmission (Fig. 1)**.

20. **Remove the transmission fill tube from the transmission**.

21. **Remove the grommet from the transmission if it did not come out with the fill tube in the previous step.**.

22. **Using special tool 8254 install the new grommet**.

23. **Install the new fill tube**.

24. **Install the bolt holding the transmission fill tube to the transmission (Fig. 1)**.

25. Set the transmission fluid level:

a. Actuate the service brake. Start engine and let it run at idle speed in selector lever position "P".

b. Shift through the transmission modes several times with the vehicle stationary and the engine idling.

c. Remove the dipstick tube cap.

d. Warm up the transmission, wait at least 2 minutes and check the oil level with the engine running.

e. Push the Oil Dipstick 9336 into transmission fill tube until the dipstick tip contacts the oil pan and pull out again, read oil level, repeat if necessary.

f. Check transmission oil temperature using the StarSCAN(TM).

g. The transmission Oil Dipstick 9336 has indicator marks every 10 mm. Determine the height of the oil level on the dipstick and using the height, the transmission temperature, and the Transmission Fluid Graph (Fig. 2), determine if the transmission oil level is correct.

h. Add or remove oil as necessary and recheck the oil level.

i. Once the oil level is correct, install the dipstick tube cap.

WARNING:
Risk of accident from vehicle starting off by itself when engine running. Risk of injury from contusions and burns if you insert your hands into the engine when it is started or when it is running. Secure vehicle to prevent it from moving off by itself. Wear properly fastened and close-fitting work clothes. Do not touch hot or rotating parts.

NOTE:
The dipstick will protrude from the fill tube when installed.

26. Drive the vehicle until the transmission fluid is at normal operating temperature to confirm that the shift shudder has been eliminated.

27. With the vehicle on a level surface, the engine running at curb idle speed, the gear selector in PARK, and the parking brake applied, check the transmission fluid level.
