REMOVAL & INSTALLATION



  1. Remove the transmission and converter as an assembly; otherwise the converter drive plate pump bushing and oil seal will be damaged. The drive plate will not support a load. Therefore, none of the weight of transmission should be allowed to rest on the plate during removal.
  2.  
  3. Attach a remote control starter switch to the starter solenoid so the engine can be rotated from under the vehicle.
  4.  
  5. Disconnect high tension cable from the ignition coil.
  6.  
  7. Remove cover plate from in front of converter assembly to provide access to the converter drain plug and mounting bolts.
  8.  
  9. Rotate engine to bring drain plug to the 6 o'clock position. Drain the converter and transmission.
  10.  

A running production change was made in January, 1977 which eliminated the converter drain plug. This means that the transmission must be removed in order to drain the converter on models manufactured after this date.

  1. Mark converter and drive plate to aid in reassembly.
  2.  
  3. Rotate the engine with the remote control switch to locate two converter to drive plate bolts located and 5 and 7 o'clock positions. Remove the two bolts, rotate engine again and remove the other two bolts.
  4.  


WARNING
Do not rotate converter on drive plate by prying with a screwdriver or similar tool as drive plate might become distorted. Also the starter should never be engaged if drive plate is not attached to converter with at least one bolt or if transmission case to engine blockbolts have been loosened.

  1. Disconnect battery ground cable. Remove engine to transmission struts, if necessary. You may have to drop the exhaust system on some models.
  2.  
  3. Remove the starter.
  4.  
  5. Remove wire from the neutral starting switch.
  6.  
  7. Remove gearshift cable or rod from the transmission and the lever.
  8.  
  9. Disconnect the throttle rod from left side of transmission.
  10.  
  11. Disconnect the oil cooler lines at transmission and remove the oil filler tube. Disconnect the speedometer cable.
  12.  
  13. Disconnect the driveshaft.
  14.  
  15. Install engine support fixture to hold up the rear of the engine.
  16.  
  17. Raise transmission slightly with jack to relieve load and remove support bracket or crossmember. Remove all bell housing bolts and carefully work transmission and converter rearward off engine dowels and disengage converter hub from end of crankshaft.
  18.  


WARNING
Attach a small C-clamp to edge of bell housing to hold converter in place during transmission removal; otherwise the front pump bushing might be damaged.

To install:

Install transmission and converter as an assembly. The drive plate will not support a load. Do not allow weight of transmission to rest on the plate during installation.

  1. Rotate pump rotors until the rotor lugs are vertical.
  2.  
  3. Carefully slide converter assembly over input shaft and reaction shaft. Make sure converter impeller shaft slots are also vertical and fully engage front pump inner rotor lugs.
  4.  
  5. Use a C-clamp on edge of converter housing to hold converter in place during transmission installation.
  6.  
  7. Converter drive plate should be free of distortion and drive plate to crankshaft bolts tightened to 55 ft. lbs. torque.
  8.  
  9. Using a jack, position transmission and converter assembly in alignment with engine.
  10.  
  11. Rotate converter so mark on converter (made during removal) will align with the mark on the drive plate. The offset holes in plate are located next to the 1 / 8 " hole in inner circle of the plate. A stamped V mark identifies the offset hole in converter front cover. Carefully work transmissio assembly forward over engine block dowels with converter hub entering the crankshaft opening.
  12.  
  13. Install converter housing to engine bolts and tighten to 28 ft. lbs.
  14.  
  15. Install the two lower drive plate to converter bolts and tighten to 270 in. lbs. torque.
  16.  
  17. Install engine to transmission struts, if required. Install starting motor and connect battery ground cable.
  18.  
  19. Rotate engine and install two remaining drive plate to converter bolts.
  20.  
  21. Install crossmember and tighten attaching bolts to 90 ft. lbs. torque. Lower transmission so that extension housing is aligned and rests on the rear mount. Install bolts and tighten to 40 ft. lbs. torque.
  22.  
  23. Remove transmission jack and engine support fixture; then install tie-bars under the transmission.
  24.  
  25. Replace the driveshaft.
  26.  
  27. Connect oil cooler lines, install oil filler tube and connect the speedometer cable.
  28.  
  29. Connect gearshift cable or rod and torque shaft assembly to the transmission case and to the lever.
  30.  
  31. Connect throttle rod to the lever at left side of transmission bell housing.
  32.  
  33. Connect wire to back-up and neutral starting switch.
  34.  
  35. Install cover plate in front of the converter assembly.
  36.  
  37. Refill transmission with fluid.
  38.  
  39. Adjust throttle and shift linkage.
  40.
