The complete procedure with details and diagrams.

The procedure is as follows:---

42RLE Automatic Transmission:

  1. Disconnect the negative battery cable.
  2. Raise and support the vehicle
  3. Remove any necessary skid plates.
  4. Mark the propeller shaft and axle companion flanges for assembly alignment.
  5. Remove the rear propeller shaft.
  6. Remove the front propeller shaft, if necessary.
  7. Disconnect the wires from the input and output speed sensors.
  8. Disconnect the wires from the transmission range sensor and the solenoid/pressure switch assembly.
  9. Remove the bolts holding the exhaust crossover pipe to the pre-catalytic converter pipe flanges.
  10. Remove the bolts holding the exhaust crossover pipe to the catalytic converter flange.
  11. Disconnect gearshift cable from transmission manual valve lever.
  12. Disengage the shift cable from the cable support bracket.
  13. Remove the starter motor.
  14. Remove the engine to transmission collar.
  15. Rotate the crankshaft in clockwise direction until the converter bolts are accessible. Then remove the bolts one at a time. Rotate the crankshaft with a socket wrench on dampener bolt.
  16. Disconnect the transmission vent hose from the transmission.
  17. Remove the transfer case on 4WD models.
  18. Support the rear of engine with a safety stand or jack.
  19. Raise the transmission slightly with a service jack to relieve the load on the crossmember and supports.
  20. Remove the bolts securing the rear support and cushion to the transmission and crossmember.
  21. Remove the bolts attaching the crossmember to frame and remove crossmember.

  22. Disconnect the transmission fluid cooler lines at the transmission fittings and clips.
  23. Remove all remaining converter housing bolts.
  24. Carefully work the transmission and torque converter assembly rearward off the engine block dowels.
  25. Hold the torque converter in place during transmission removal.
  26. Lower the transmission and remove the assembly from under the vehicle.
  27. To remove the torque converter, carefully slide the torque converter out of the transmission.
To install:
  1. Check the 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 the oil pump seal lip with transmission fluid.
  4. Align the converter and oil pump.
  5. Carefully insert the converter in the oil pump. Then rotate the converter back and forth until fully seated in the pump gears.
  6. Check the converter seating with a steel scale and straightedge. The surface of the converter lugs should be at least 13mm ( 1 / 2 in.) to the rear of straightedge when the converter is fully seated.
  7. Temporarily secure the converter with a C-clamp.
  8. Position the transmission on the jack and secure it with chains.
  9. Check the condition of the converter driveplate. Replace the plate if cracked, distorted or damaged. Also, be sure the transmission dowel pins are seated in the engine block and protrude far enough to hold the transmission in alignment.
  10. Apply a light coating of high temperature grease to the torque converter hub pocket in the rear pocket of the engine-s crankshaft.
  11. Raise the transmission and align the torque converter with the drive plate and transmission converter housing with the engine block.
  12. Move the transmission forward. Then raise, lower or tilt transmission to align the converter housing with engine block dowels.
  13. Carefully work the transmission forward and over the engine block dowels until the converter hub is seated in the crankshaft. Verify that no wires, or the transmission vent hose, have become trapped between the engine block and the transmission.
  14. Install the two bolts to attach the transmission to the engine.
  15. Install the remaining torque converter housing to engine bolts. Tighten to 68 Nm (50 ft. lbs.).
  16. Install the transfer case, if equipped. Tighten the transfer case nuts to 35 Nm (26 ft. lbs.).
  17. Install the rear transmission crossmember. Tighten the crossmember to frame bolts to 68 Nm (50 ft. lbs.).
  18. Install the rear support to the transmission. Tighten the bolts to 47 Nm (35 ft. lbs.).
  19. Lower the transmission onto the crossmember and install the bolts attaching the transmission mount to the 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.).
  20. Remove the engine support fixture.
  21. Connect the gearshift cable to the support bracket and transmission manual lever.
  22. Connect the input and output speed sensor wires.
  23. Connect the wires to the transmission range sensor and the solenoid/pressure switch assembly.
  24. Install the torque converter-to-driveplate bolts. Tighten the bolts to 88 Nm (65 inch lbs.).
  25. Install the starter motor and cooler line bracket.
  26. Connect the cooler lines to transmission.
  27. Install the transmission fill tube.
  28. Install the exhaust components.
  29. Align and connect the propeller shaft(s).
  30. Adjust the gearshift cable if necessary.
  31. Install any skid plates removed previously.
  32. Lower the vehicle.
  33. Fill the transmission with the required amount of Mopar® ATF +4, Automatic Transmission Fluid.
