Service Information: Installation

NOTE: 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. The hub must be smooth to avoid damaging pump seal at installation.
  1. 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.
  2. Lubricate oil pump seal lip with transmission fluid.

    2 - STRAIGHTEDGE
  3. Align converter and oil pump.
  4. Carefully insert converter in oil pump. Then rotate converter back and forth until fully seated in pump gears.
  5. Check converter seating with steel scale (1) and straightedge (2). See Fig 1. Surface of converter lugs should be at least 13mm (1/2 in.) to rear of straightedge when converter is fully seated.
  6. Temporarily secure converter with C-clamp.
  7. Position transmission on jack and secure it with chains.
  8. Check condition of converter driveplate. 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. 
  9. Apply a light coating of Mopar® High Temp Grease to the torque converter hub pocket in the rear pocket of the engine's crankshaft.
  10. Raise transmission and align the torque converter with the drive plate and transmission converter housing with the engine block.
  11. Move transmission forward. Then raise, lower or tilt transmission to align the converter housing with engine block dowels.
  12. 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.
  13. Install two bolts to attach the transmission to the engine.
  14. Install remaining torque converter housing to engine bolts. Tighten to 68 N.m (50 ft.lbs.).
  15. Install transfer case, if equipped. Tighten transfer case nuts to 35 N.m (26 ft.lbs.).
  16. Install rear transmission crossmember. Tighten crossmember to frame bolts to 68 N.m (50 ft.lbs.).
  17. Install rear support to transmission. Tighten bolts to 47 N.m (35 ft.lbs.).
  18. Lower transmission onto crossmember and install bolts attaching transmission mount to crossmember. Tighten clevis bracket to crossmember bolts to 47 N.m (35 ft.lbs.). Tighten the clevis bracket to rear support bolt to 68 N.m (50 ft.lbs.).

    CAUTION: It is essential that correct length bolts be used to attach the converter to the driveplate. Bolts that are too long will damage the clutch surface inside the converter.
  23. Install torque converter-to-driveplate bolts. Tighten bolts to 88 N.m (65 in. lbs.).
  24. Install starter motor and cooler line bracket.
  25. Connect cooler lines (1) to transmission. See Fig 5.
