Nag1 Automatic Transmission (Service Information): Installation

  1. Check torque converter hub and hub drive flats for sharp edges burrs, scratches, or nicks. Polish the hub and flats with 800/1000 grit paper and crocus cloth if necessary. 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. Place torque converter (1) in position in transmission (2).
    CAUTION: Do not damage oil pump seal or converter hub while inserting torque converter into the front of the transmission.
  5. Align torque converter to oil pump seal opening.
  6. Insert torque converter hub into oil pump.
  7. While pushing torque converter inward, rotate converter until converter is fully seated in the oil pump gears.
  8. 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.
  9. If necessary, temporarily secure converter with C-clamp attached to the converter housing.

  10. 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. 
  11. Apply a light coating of Mopar® High Temp Grease to the torque converter hub pocket in the rear pocket of the engine's crankshaft.
  12. Raise transmission (3) and align the torque converter with the drive plate and the transmission converter housing with the engine block (1).
  13. Move transmission forward. Then raise, lower, or tilt transmission to align the converter housing with the engine block dowels.
  14. While installing the fill tube into the transmission case, 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.
  15. Install two torque converter housing bolts (2) to attach the transmission to the engine.
  16. Install remaining to engine bolts (2). Tighten to 39 N.m (29 ft.lbs.).
  17. Install the fill tube bolt at the transmission case. Tighten the bolt to 12 N.m (105 lbs in.).
