Automatic Transmission

  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 steel scale and straightedge. Surface of converter lugs should be at least 13 mm (1/2 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 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. 
  10. Apply a light coating of Mopar® 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 drive plate and the transmission converter housing with the engine block.
    NOTE: Before aligning the transmission to the engine block fit the transmission fill tube to the vehicle.
  12. Move transmission forward. Then raise, lower, or tilt transmission (2) to align the converter housing with the engine (1) block dowels. See Fig 1.
  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.
