Service Procedure
1. Position the vehicle on an appropriate hoist, apply the park brake and place the transaxle shifter in the "Low" position.2. Open the hood.
3. Disconnect the negative battery cable.
4. For JR and PT models, remove the air cleaner assembly.
5. For PL models, remove the air cleaner and throttle body as an assembly.
6. Remove the manual valve lever from the manual valve shaft (Figure 1)
7. For JR, PL and RS models, disconnect the transaxle range selector connector from the transaxle (Figure 1)
8. Raise the vehicle on an appropriate hoist.
9. For PT models, disconnect the transaxle range selector connector from the transaxle.
10. For RS models, temporarily relocate the wiring harness located at the front of the transaxle oil pan rail.
11. For JR models, remove the left side brake-cooling duct.
12. With a drain pan in position, remove the transaxle-to-oil pan bolts and carefully separate the pan from the transaxle case.
13. Remove and save the transaxle oil filter from the valve body.
14. Remove the valve body-to-transaxle case bolts.
NOTE:
The manual valve shaft on the valve body must be fully clockwise ("Low" position) to position the park rod for removal.
15. Using a screwdriver, push the park rod rollers away from the guide bracket and lower the valve body.
CAUTION:
The underdrive and overdrive accumulators and springs will drop out of the transaxle case when lowering the valve body.
NOTE:
The underdrive and overdrive accumulator springs are not interchangeable.
16. Remove the original low/reverse accumulator snap ring (Figure 2).
NOTE:
The low/reverse accumulator cover, piston and springs may drop out when the accumulator cover snap ring is removed.
17. Remove and discard the original low/reverse accumulator cover and 0-ring.
18. Install the new 0-ring onto the new low/reverse accumulator cover.
19. With the low/reverse accumulator and springs in place, install the new low/reverse accumulator cover and 0-ring into the transaxle case (Figure 2).
20. Install the low/reverse accumulator snap ring (Figure 2).
21. Clean the transaxle case-to-oil pan sealing surface.
22. While holding the overdrive and underdrive accumulators and springs in position, install the valve body to the transaxle case. Tighten the valve body attaching bolts to 105 in.lbs. (12 N.m).
NOTE:
The underdrive accumulator has a double return spring (Figure 3). The overdrive accumulator has a single return spring (Figure 3).
23. Inspect the transaxle oil filter 0-ring and replace if necessary.
24. Install the original transaxle oil filter.
25. Clean the transaxle oil pan sealing surfaces.
26. Apply a 1/8 inch bead of Mopar ATE-RTV (P/N 05010884AA) to the oil pan sealing surface and immediately install the pan on the transaxle.
CAUTION:
Do not use other types of silicone RTV to seal the transaxle oil pan to the transaxle case. Leaks and/or transmission fluid contamination may result.
27. Install the transaxle oil pan attaching bolts and tighten the bolts to 165 in.lbs. (19 N.m).
28. For RS models, place the wiring harness at the front of the oil pan rail back in its original location.
29. For JR models, install the left side brake-cooling duct.
30. For PT models, connect the transaxle range selector connector to the transaxle (Figure 1).
31. Lower the vehicle.
32. For JR, PL and RS models, connect the transaxle range selector connector to the transaxle (Figure 1).
33. Install the manual valve lever to the manual shaft.
34. Connect the negative battery cable.
35. For JR and PT models, install the air cleaner assembly.
36. For PL models, install the air cleaner/throttle body assembly.
37. Fill the transaxle with 4 quarts (3.8L) of Mopar ATF+4 transmission fluid.
CAUTION:
Use only Mopar ATF+4 transmission fluid. Do not use Mopar ATF+3 (7176), Dexron III, Mercon, or Type "F" transmission fluid.
38. Place the transaxle selector lever in the "P" Park position. With the vehicle on level ground, start the engine and allow the engine to ruin at idle speed for at least one minute. At normal operating temperature 180°F (82°C), the fluid level is correct if it is in the "HOT" region on the transaxle dipstick. The fluid level should be within the "COLD" region of the dipstick at 80°F (27°C) fluid temperature. Add additional ATF+4 transmission fluid as required and recheck level (Figure 4).
39. Perform the Transaxle Control Module (TCM) Quick Learn Procedure below:
NOTE:
To perform the Quick Learn Procedure, the following conditions must be met:
> The brakes must be applied.
> The engine speed must be above 500 rpm.
> The throttle angle (TPS) must be less than 3 degrees.
> The shift lever position must stay until prompted to shift to overdrive.
> The shift lever position must stay in overdrive after the "Shift to Overdrive" prompt until the DRBIII(B) indicates the procedure is complete.
> The calculated transmission fluid temperature must be between 60° F (15° C) and 200° F (93° C).
a. Connect the DRBIII scan tool to the diagnostic connector. The connector is located under the instrument panel, near the steering column.
b. From the DRBIII main menu choose "DRB Standalone" and press enter.
c. Select "2002 Model Year" and press enter.
d. Select "ALL" and press enter.
e. In the "Select Systems" screen choose "Transmission" and press enter.
f. In the "Transmission Menu" screen choose "Transmission Module" and press enter.
g. In the "Select Functions" screen choose "Miscellaneous" and press enter.
h. In the "Select Miscellaneous Functions" screen choose "Quick Learn" and press enter.
i. Follow the instructions on the DRBIII screen to perform the Quick Learn Procedure.
j. Disconnect the DRBIII.
40. Ensure that there are no transmission fluid leaks and then close the hood.
