  1. Remove torque converter and mount transaxle assembly to a holding fixture or place on work bench, with oil pan in down position. Remove oil level gauge, tube and bracket. Remove inhibitor switch, vehicle speed sensor, oil pan protector and oil pan. See Fig 1 .
  2. Turn transaxle so valve body faces up. Remove terminal clip of solenoid wires. Remove bolts (15) attaching valve body assembly to transaxle case. Remove valve body assembly with terminal assembly and remove manual valve. See Fig 1 .
  3. Remove 4 lip seals, low and reverse brake sleeve and 2-3 accumulator return spring from transaxle case. See Fig 2 .
  4. Turn transaxle so converter housing faces up. Remove converter housing-to-transaxle case bolts and remove converter housing. Remove differential. Remove "O" ring from input shaft. Remove oil pump-to-transaxle case bolts and remove oil pump assembly. Remove "O" ring from oil hole for differential gear lubrication oil. See Fig 1 .
  5. Loosen anchor end bolt lock nut and remove anchor end bolt. Remove brake band and use wire to secure brake band in closed position. Remove input shaft, reverse clutch, high clutch, high clutch hub and front sun gear as an assembly. Remove thrust bearing and bearing race. See Fig 3 .
  6. Using Servo Piston Compressor (J-25024) or suitable tool, compress servo retainer and remove snap ring. Remove servo retainer, servo piston and return spring. See Fig 3 . Remove side cover and output gear.
  7. Using Low and Reverse Brake Spring Compressor (J-38298) and Bridges (J-35279-1 and J-35279-9) or suitable tool, compress front planetary carrier and remove snap ring. Remove front planetary carrier, low and reverse brake piston and retainer. Remove 2 thrust bearings from front planetary carrier. See Fig 6 .
  8. Remove rear sun gear and rear planetary carrier. Remove thrust bearing from rear planetary carrier. Remove rear internal gear and forward clutch hub. Remove overrun clutch hub. Remove thrust washer and bearing race from overrun clutch hub. Remove forward clutch assembly. Remove thrust bearing from forward clutch assembly. Remove low and reverse brake snap ring, dished plate, 2 spacer plates and drive and driven plates. See Fig 4 .
  9. Use punch to remove crimp of idler gear lock nut. Set selector lever in piston to lock idler gear and remove idler gear lock nut. Using Idler Gear Puller (J-38297) or suitable tool, pull idler gear from reduction gear shaft. Remove reduction gear from transaxle case. Remove 5 bolts attaching reduction gear bearing outer race and remove outer race. See Fig 5 .
  10. Remove thrust bearing from drum support and remove drum support. Apply air pressure to 2-3 and N-D accumulator oil passages to remove 2-3 and N-D accumulator pistons. Remove "O" ring from each piston and remove N-D accumulator piston return spring. See Fig 6 .
  11. Remove parking lever, parking rod, return spring, parking shaft, parking pawl and parking actuator support. Drive out spring pin from manual plate and remove manual plate. Remove manual shaft locating bolt and remove manual shaft. See Fig 5 . Remove manual shaft "O" ring. Remove detent spring and support plate.
  12. Using Puller Bridge (J-33367), Puller (J-35280) and Bridges (J-35279-1 and J-35279-3) or suitable puller, remove idler gear bearing outer race from transaxle case. Using puller, remove differential bearing outer race and shim from transaxle case and differential bearing outer race from converter housing. Using puller bridge and Remover (J-26941) or suitable tool, remove axle shaft seals from transaxle case and converter housing. See Fig 5 .
