Valve Body & Components

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.
CAUTION: Note location of all thrust washer and thrust plate locations for reassembly reference.
  1. Remove torque converter. Loosen clamps and remove throttle valve and manual shift levers from transmission.
    CAUTION: If alignment shaft is not installed in overdrive unit, components may become out of alignment and overdrive unit must be disassembled to realign components.
  2. Remove overdrive unit-to-transmission bolts. Remove overdrive unit. See Fig 2 . If overdrive unit does not require servicing, install Alignment Shaft (6227-2) in overrunning clutch and planetary gear splines on overdrive unit, ensuring alignment shaft is fully seated. See Fig 3 . This maintains proper alignment of all components in overdrive unit.
  3. Remove intermediate shaft selective spacer and overdrive piston thrust plate from intermediate shaft. See Fig 2 . Remove overdrive piston from overdrive piston retainer.
  4. Inspect that check ball on front side of overdrive piston is secure in the overdrive piston and is not loose. Replace overdrive piston if check ball is loose.

  5. Remove bolts, oil pan and gasket. Remove park/neutral switch and seal. Remove bolts and filter assembly. Keep bolts with filter assembly for reassembly reference.
  6. Disconnect solenoid electrical connectors from solenoid connector in transmission case. Remove valve body-to-transmission case bolts. Note bolt length and location for reassembly reference.
  7. Lift valve body upward. Push manual shift lever and solenoid connector from transmission case. Guide park rod out of transmission case. Remove valve body. Remove accumulator and springs. Note location of springs for reassembly reference.
  8. Remove plug from front band pin access hole located in front of transmission case, near top of oil pump. See Fig 5 . Loosen lock nut on front band adjusting screw approximately 5 revolutions. See Fig 4 . Tighten front band adjusting screw until front band is tight. This prevents clutch components from coming out when oil pump is removed.

  9. Remove oil pump bolts. Install slide hammers on opposite sides of oil pump. Pull oil pump from transmission case. Remove oil pump gasket.
  10. Loosen front band adjusting screw until front band is loose. Squeeze front band together. Remove front band strut located between lever on transmission case and front band. Remove anchor located between other side of transmission case and the band.
  11. Remove front band pin through front band pin access hole. Remove lever for front band. Squeeze front band together and remove from transmission case.
  12. Grasp input shaft, hold clutch units together, and remove front 6and rear clutch as an assembly. See Fig 5 . Remove triangular shaped thrust washer from intermediate shaft. This thrust washer may remain on hub of rear clutch.

  13. Remove the thrust plate from the end of the intermediate shaft. See Figure . Remove intermediate shaft and planetary gear train assembly.
    CAUTION: DO NOT  damage machined surfaces on intermediate shaft during removal.
  14. On 46RH and 46/47RE loosen rear band adjusting screw 3-4 turns. See Fig 4 . Remove low-reverse drum-to-overdrive piston retainer snap ring from inside of transmission case.
  15. Remove low-reverse drum from rear band and remove from transmission case. Tap pin for rear band toward rear of transmission case. Remove rear band linkage, lever, pin and rear band.
  16. On 47RH, low-reverse drum and rear band are removed as an assembly. Loosen rear band adjusting screw 4-5 turns. See Fig 4 . Using Allen wrench, push pivot pin for rear band out of rear of transmission case. Perform step 1. See Fig 6 .
  17. Using small punch, push rear band reaction pin out of rear of transmission case. Perform step 2. See Fig 7 .
  18. Remove low-reverse drum-to-overdrive piston retainer snap ring from inside of transmission case. Remove low-reverse drum and rear band from transmission case as a unit. Remove rear band from low-reverse drum.
