Disassembly Procedure

  1. Remove the torque converter, and immediately turn it so that the hole faces upward. This will help to keep any remaining fluid from spilling.
  2. Pull out the oil pump shaft by hand.
  3. Remove the oil dipstick and oil filler tube.
  4. Remove the O-ring from the oil filler tube.
  5. Remove the breather hose.
  6. Assemble the SST  .

    NOTE:
    • When the manual shaft lever is installed to the manual shaft, use an adjustable wrench to hold the manual shaft lever, then use a wrench other than an impact wrench to remove the manual shaft nut and manual shaft lever.
    CAUTION:
    • Do not use an impact wrench or remove the manual shaft nut without holding the manual shaft lever, as the transaxle may become damaged.
  9. Remove the manual shaft nut.
  10. Remove the input/turbine speed sensor, TR switch, and bracket.
  11. Remove the O-ring from the input/turbine speed sensor.
  12. Remove the vehicle speedometer sensor.
  13. Remove the O-ring from the vehicle speedometer sensor.
  14. Disconnect the coupler.
  15. Remove the connector bolt.
  16. Remove the oil pipe, packing, spring, and steel ball.
    WARNING:
    • Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eye wear whenever using compressed air.
    CAUTION:
    • Clean the transaxle exterior thoroughly with a steam cleaner or cleaning solvents before removal.
    • If any old sealant gets into the transaxle during installation of the oil pan, trouble may occur in the transaxle. Remove any old sealant from the transaxle case and oil pan, and clean with cleaning fluids.
  17. Remove the oil pan and inspect any material found in the pan or on the magnet to determine the condition of the transaxle.
    • If large amounts of material are found, replace the torque converter and carefully check the transaxle for the cause.
      • Clutch facing material: Drive plate and brake band wear
      • Steel (magnetic): Bearing, gear, and driven plate wear
      • Aluminum (nonmagnetic): Aluminum part wear
  18. Remove the oil strainer and O-ring.
    CAUTION:
    • If any old sealant gets into the transaxle during installation of the control valve body cover, trouble may occur in the transaxle. Remove any old sealant from the transaxle case and control valve body cover, and clean with cleaning fluids.
  19. Remove the control valve body cover.
  20. Disconnect the solenoid connectors and TFT sensor connector.
  21. Remove the coupler component.
