INSTALLATION




1. Check torque converter hub and hub drive flats for sharp edges burrs, scratches, or nicks. Polish the hub and flats with 320/400 grit paper and crocus cloth if necessary. Verify that the converter hub O-ring is properly installed and is free of any debris. The hub must be smooth to avoid damaging pump seal at installation.
2. If a replacement transmission is being installed, transfer any components necessary, such as the manual shift lever and shift cable bracket, from the original transmission onto the replacement transmission.
3. Lubricate oil pump seal lip with transmission fluid.
4. Align converter and oil pump.
5. Carefully insert converter in oil pump. Then rotate converter back and forth until fully seated in pump gears.
6. Check converter seating with a scale and straightedge (A). Surface of converter lugs should be at least 19 mm (3/4 in.) to rear of straightedge when converter is fully seated.
7. Temporarily secure converter with C-clamp.
8. Position transmission on jack and secure it with chains.
9. Check condition of converter flexplate. Replace the plate if cracked, distorted or damaged. Also be sure transmission dowel pins are seated in engine block and protrude far enough to hold transmission in alignment.
10. Apply a light coating of MOPAR(R) High Temp Grease to the torque converter hub pocket in the rear pocket of the engine's crankshaft.
11. Raise transmission and align the torque converter with the flex plate and transmission converter housing with the engine block.
12. Move transmission forward. Then raise, lower or tilt transmission to align the converter housing with engine block dowels.
13. Carefully work transmission forward and over engine block dowels until converter hub is seated in crankshaft. Verify that no wires, or the transmission vent hose, have become trapped between the engine block and the transmission.




14. Install two bolts (2) to attach the transmission to the engine.
15. Install remaining torque converter housing to engine bolts. Tighten to 39 Nm (29 ft.lbs.).
16. Install transfer case (if equipped).




17. Install rear support to transmission. Tighten bolts to 47 Nm (35 ft.lbs.).
18. Lower transmission onto crossmember and install bolts attaching transmission mount to crossmember. Tighten clevis bracket to crossmember bolts to 47 Nm (35 ft.lbs.). Tighten the clevis bracket to rear support bolt to 68 Nm (50 ft.lbs.).
19. Remove safety stand or jack from under engine and transmission.

NOTE: Transmission cooler line mounting clips are single use only and must be replaced when ever removed.




29. Connect cooler lines (2) into transmission.





NOTE: Inspect the fill tube grommet to determine if the grommet is new or used. If a new fill tube grommet is in the transmission case, pierce the center of the grommet with a ballpoint pen, or similar instrument, to prepare the grommet for the fill tube installation.

30. Install transmission fill tube and bolt. Tighten bolts to 10 Nm (88 in.lbs.)
31. Install transmission fill tube heat (1) shield and bolts (2). Tighten bolts to 10 Nm (88 in.lbs.)
