- Refer to: DUAL CATALYTIC CONVERTER Y-PIPE .
- Refer to: STARTER MOTOR .
- Remove the rubber torque converter nut access cover.
-
NOTE: Index-mark the end of one torque converter stud and the flexplate for installation.NOTE: Using the crankshaft pulley bolts, turn the engine clockwise.
Remove and discard the torque converter nuts (W715618).
- Remove the bolts and the flexplate inspection cover.
-
- Rotate the shell of the transmission vehicle harness connector counterclockwise and disconnect the transmission vehicle harness connector.
- Detach the wiring harness retainer from the transmission case.
-
- Disconnect the selector lever cable from the manual control lever.
- Remove the bolts and position the selector lever cable and bracket aside.
- Remove the wiring harness retainers from the transmission case and position the wiring harness aside.
-
NOTE: Only use hand tools when loosening the engine support insulator nuts or damage to the engine support insulator may occur.NOTE: The RH engine support insulator studs may come out of the insulator while removing the nuts. Install new RH engine support insulator studs if the studs come out.
Detach and discard the RH engine support insulator nuts.
-
NOTE: Only use hand tools when loosening the engine support insulator nuts or damage to the engine support insulator may occur.
Remove and discard the LH engine support insulator nuts.
Rear Wheel Drive (RWD) vehicles
-
NOTE: When removing the crossmember, support the transmission using a heavy duty transmission jack.
- Place the jack so the fluid pan does not support the weight of the transmission.
- Fasten a chain or ratchet strap over the top of the transmission and to both sides of the jack.
Failure to use a heavy duty transmission jack can result in damage to the transmission.
NOTE: The transmission support insulator studs may come out of the transmission support insulator while removing the transmission support insulator-to-crossmember nuts. Install new transmission support insulator studs if the studs come out.Remove the transmission support crossmember. Refer to: Transmission Support Crossmember .
Rear Wheel Drive (RWD) vehicles equipped with a slip yoke
- Remove the rear driveshaft. Refer to: Rear Driveshaft .
-
NOTE: If installing a new, remanufactured or overhauled transmission.
Remove and discard the transmission support insulator-to-transmission bolts. Remove the transmission support insulator.
Rear Wheel Drive (RWD) vehicles equipped with a fixed yoke
-
NOTE: It may be necessary to tap the driveshaft yoke with a plastic or rubber soft-faced hammer if a pry area is not present on the driveshaft side.
- Index mark the rear driveshaft.
- Remove and discard the driveshaft to output shaft flange bolts and straps (4A254).
- Remove and discard the center bearing mounting bolts from the center bearing bracket. Position aside and support the driveshaft.
-
NOTE: If installing a new, remanufactured or overhauled transmission.
Remove and discard the transmission support insulator bracket to transmission bolts. Remove the transmission support insulator and bracket.
Vehicles equipped with Four-Wheel Drive (4WD) and a manual shift transfer case
-
- Disconnect the transfer case linkage cable from selector lever.
- Detach the rotating slide snap ring (7H181) and position the transfer case linkage aside.
- Remove the nuts and the transfer case linkage bracket.
Four-Wheel Drive (4WD) vehicles
-
NOTE: When removing the crossmember, support the transmission using a heavy duty transmission jack.
- Place the jack so the fluid pan does not support the weight of the transmission.
- Fasten a chain or ratchet strap over the top of the transmission and to both sides of the jack.
Failure to use a heavy duty transmission jack can result in damage to the transmission.
NOTE: If the transmission is being removed for the flexplate or engine related repairs, the transfer case does not need to be separated from the transmission.Remove the transfer case. Refer to: Transfer Case .
All vehicles
- Remove the bolt and position the transmission fluid cooler tubes aside.
- Inspect the transmission to be sure the transmission fluid tube seals and backing rings were removed with the transmission fluid tubes and are not stuck in the transmission. If the transmission fluid tube seals or backing rings are stuck in the transmission, remove the seals and backing rings.
- Remove the lower transmission fluid filler tube bolt and position the transmission fluid filler tube aside.
- Remove and discard the transmission fluid filler tube O-ring (391308).
-
NOTE: Secure the transmission to the transmission jack with a safety strap or chain.NOTE: Make sure the transmission jack makes contact on the outer ribs of the transmission fluid pan.
Using a high-lift transmission jack, support the transmission.
- Outer ribs of the transmission fluid pan.
Use the General Equipment: Transmission Jack
- Safety chain.
- Outer ribs of the transmission fluid pan.
-
NOTE: Note the location of the longer bolt for installation.
Remove the RH transmission-to-engine bolts.
- Remove the upper bellhousing bolts and position aside the fuel tube bracket.
-
NOTE: Be sure to position the Torque Converter Retainer in the proper position to ensure the torque converter is held securely in place.
Slide the transmission back enough to install the special tool and remove the transmission.
Install Special Service Tool: 307-346 (T97T-7902-A) Retainer, Torque Converter.
-
NOTE: Failure to flush the transmission fluid cooler and transmission fluid cooler tubes can result in metallic contamination of the transmission.
If installing a new, remanufactured or overhauled transmission, clean and backflush the transmission fluid cooler tubes to prevent repeat repairs. Refer to: Transmission Fluid Cooler - Backflushing and Cleaning .
-
NOTE: Failure to install a new auxiliary transmission fluid cooler can result in metallic contamination of the transmission.
If installing a new, remanufactured or overhauled transmission install a new auxiliary transmission fluid cooler if equipped.
-
NOTE: Failure to clean the Power Take-Off (PTO) can result in metallic contamination of the transmission.
For vehicles equipped with a PTO assembly, prior to installing the transmission, flush and clean the PTO assembly to remove any foreign material. Failure to remove foreign material from the PTO assembly may result in subsequent transmission concerns.
