  1. Disconnect the negative battery cable.
  2.  
  3. Raise and support the vehicle safely.
  4.  
  5. Remove the left front tire.
  6.  
  7. Drain the transaxle fluid.
  8.  
  9. Remove the left side fender protector.
  10.  
  11. Remove the halfshafts.
  12.  

Be careful not to damage the oil seals when removing the halfshafts. After removing the halfshafts, install a suitable bar so the side gears will not rotate and fall into the differential case.

  1. On Sentra Wagon, disconnect and remove the forward exhaust pipe.
  2.  
  3. Disconnect the speedometer cable.
  4.  
  5. Disconnect the throttle wire (cable) connection.
  6.  
  7. Remove the control cable rear end from the unit and remove the oil level gauge tube.
  8.  
  9. Place a suitable jack under the transaxle and engine. Do not place the jack under the oil pan drain plug. Support the engine with wooden blocks placed between the engine and the center member.
  10.  
  11. Disconnect the oil cooler and charging tubes. Plug the tube ends to prevent leakage.
  12.  
  13. Remove the engine motor mount securing bolts, as required.
  14.  
  15. Remove the starter motor and disconnect all electrical wires from the transaxle.
  16.  
  17. Loosen and remove all but 3 of the bolts holding the transaxle to the engine. Leave the 3 bolts in to support the weight of the transaxle while removing the converter bolts.
  18.  
  19. Remove the driveplate or dust covers.
  20.  
  21. Remove the bolts holding the torque converter to the driveplate. Rotate the crankshaft to gain access to each bolt. Before separating the torque converter, place chalk marks on 2 parts for alignment purposes during installation.
  22.  

The transaxle bolts are different lengths. Tag each bolt according to location to ensure proper installation.

  1. Remove the 3 temporary bolts. Move the jack gradually until the transaxle can be lowered and removed from the vehicle through the left side wheel housing.
  2.  
  3. Check the driveplate run-out with a dial indicator. Run-out must be no more than 0.020 in. (0.5mm).
  4.  

To install:
  1. If the torque converter was removed from the engine for any reason, after it is installed, the distance from the face of the converter to the edge of the transaxle housing (distance A ) must be checked prior to installing the transaxle. This is done to ensure proper installation of the torque converter. Check the distance and make sure it is as follows: RL3F01A transaxles should be 0.831 in. (21mm) or more, RL4F03A and RL4F03V transaxles should be 0.748 in. (19mm) or more.
  2.  
  3. Raise the transaxle onto the engine and install the torque converter-to-driveplate bolts. Torque the bolts to specification. Install 3 bolts to support the transaxle while tighten the converter bolts.
  4.  

After the converter Is Installed, rotate the crankshaft several times to make sure the transaxle rotates freely and does not bind.

  1. Install the driveplate or dust covers.
  2.  
  3. Install the transaxle mounting bolts and tighten as follows:

    1982-89 vehicles, tighten bolts (1), (2) and (3) to 29-36 ft. lbs. (39-49 Nm and bolts (4) to 22-30 ft. lbs. (30-40 Nm).
     
    1990 vehicles, tighten bolts (1) to 29-36 ft. lbs. (39-49 Nm) and bolts (2) to 22-30 ft. lbs. (30-40 Nm).
     

  4.  
  5. Connect the transaxle wiring and install the starter.
  6.  
  7. Install the engine mounts, if removed.
  8.  
  9. Connect the oil cooler and charging tubes.
  10.  
  11. Remove the engine and transaxle supports.
  12.  
  13. Install the oil level gauge tube and control cable rear end.
  14.  
  15. Connect the throttle wire (cable) connection.
  16.  
  17. Connect the speedometer cable.
  18.  
  19. On Sentra wagon, install the front exhaust pipe using new gaskets.
  20.  
  21. Install the halfshafts.
  22.  
  23. Install the left side fender protector.
  24.  
  25. Mount the left front tire and lower the vehicle.
  26.  
  27. Fill the transaxle and engine with the proper amounts of fluids.
  28.  
  29. Adjust the control cable and throttle wire.
  30.  
  31. Check the inhibitor switch for proper operation.
  32.  
  33. Road test the vehicle.
  34.
