REPAIR PROCEDURE NO. 2:

This procedure involves either flashing the TCM with new calibrations or replacing the TCM if it can not be flashed, changing the transmission fluid, driving the vehicle 10 miles and changing the transmission fluid again and on 1993 and later models, setting the Pinion Factor and performing the Quick Learn procedure.

1. Perform steps 1-12 (as applicable) of REPAIR PROCEDURE NO. 1.

2. Disconnect the DRB III and MDS from the vehicle.

3. Change the transmission fluid using following the procedure:

A) Raise the vehicle with an appropriate hoist.

B) Clean the transaxle oil pan and mating area thoroughly.

C) Remove the transaxle oil pan. Remove all sealant from the transaxle oil pan and mating area. Clean the inside of the oil pan and magnet.

D) Check the transaxle oil filter engagement and O-ring condition. Cut or poorly installed 0-rings also may cause delayed garage shifts.

E) Separate the transaxle oil filter and O-ring from the valve body and discard.

F) Install the new oil filter specified in the Parts Required section of this TSB.

G) Apply an 1/8 in. bead of Mopar RTV sealant, P/N 4318025, on the mounting flange of the transaxle oil pan. Apply Mopar RTV sealant to the underside of the attaching bolts. Torque the attaching bolts to 19 Nm (165 in. lbs.).

NOTE:
USE ONLY MOPAR ATF PLUS TRANSMISSION FLUID AUTOMATIC TRANSMISSION FLUID TYPE 7176 (PIN 4467721). USE OF DEXTRON IIE OR DEXTRON III MAY CAUSE CLUTCH SHUDDER.

H) Pour 4 quarts Mopar Automatic Transmission Fluid Type 7176 through the fill tube.

J) Check the transaxle fluid level and add an appropriate amount of transmission fluid to bring the level to 1/8 in. (3 mm) below the ADD mark on dipstick.

K) Recheck the fluid level after the transaxle is at normal operating temperature. The level should be in the HOT range of the dipstick.

4. Drive the vehicle at least 10 miles.

5. Repeat step 3A - 3C of REPAIR PROCEDURE NO. 2.

6. Separate the transaxle oil filter and O-ring from the valve body and drain the fluid from it. This also allows for additional fluid to drain from the transmission.
