WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 1996 Dodge Ram Wagon, 1996 Dodge Ram Van, 1996 Dodge Pickup, 1996 Dodge Dakota, and 1996 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. On 46/47RE models, disconnect wires from governor pressure sensor and governor pressure solenoid located on the valve body. See Fig 1 . Remove bolts, governor body retainer plate, governor body and gasket from transfer plate. If removing governor pressure sensor from governor body, remove clip from inside of governor body. Remove governor pressure sensor from governor body.
  2. If removing governor pressure solenoid from governor body, pull governor pressure solenoid with "O" rings straight out of governor body. Remove boost valve cover, retainer, boost valve spring, boost valve and boost valve plug (if equipped). See Fig 2 . Depress detent ball. Install Detent Ball Retainer (6583) on ball and spring housing to secure detent ball and spring in housing.
  3. Remove clip and washer (if equipped) from throttle valve lever. Lift manual shift lever and park rod from throttle valve lever. See Figure . Remove detent ball retainer. Remove detent ball and spring. Remove throttle valve lever.
  4. Remove retaining clip. Separate park rod from manual shift lever. Hold adjusting screw bracket against valve body and remove screws. See Figure .

    CAUTION: DO NOT  disturb throttle pressure adjusting screw or line pressure adjusting screw locations in adjusting screw bracket.
  5. Remove adjusting screw bracket, line pressure adjusting screw, pressure regulator valve spring (large spring) and switch valve spring (small spring).
  6. Note routing of solenoid wiring. Remove solenoid assembly, gasket, 3-4 accumulator housing and case connector from lower housing. See Fig 4 . Case connector uses a shoulder-type screw and must be installed in original location.
    CAUTION: Use care not to damage housings or tube when removing boost valve tube. Disengage boost valve tube from upper housing first and then from the lower housing. DO NOT  pry boost valve tube from the housing
  7. Remove spring, 3-4 shift valve, plug, spring and lock-up valve. See Fig 4 . Pull boost valve tube from upper housing first and then from the lower housing. See Figure . It may be necessary to rotate boost valve tube back and forth when removing from lower housing.
  8. Position valve body so lower housing faces upward, with upper housing on bottom. See Figure .
    CAUTION: Ensure lower housing faces upward before removing valve body screws. This prevents check balls from falling out of upper housing.
  9. Note location of brace for the boost valve tube. Remove valve body screws attaching lower housing to the upper housing. Remove lower housing and separator plate from transfer plate.
  10. Remove lower housing from transfer plate. Remove transfer plate and both separator plates from upper housing. Note location of check balls in upper housing. See Fig 5 .
    CAUTION: Some valve bodies may contain the rear servo check ball and rear clutch check ball and some may not. Note original number of check balls during disassembly for reassembly reference.
  11. Position transfer plate with separator plate for upper housing facing upward. Remove screws, separator plate brace and separator plate for upper housing. See Fig 6 .
