1. INSPECT OVERDRIVE ONE-WAY CLUTCH


AT08138E01

  1. Hold the overdrive direct clutch drum, and turn the input shaft.
    Check that the input shaft can be turned freely clockwise and locks when turned counterclockwise.



2. REMOVE OVERDRIVE DIRECT CLUTCH DRUM


3. INSPECT OVERDRIVE DIRECT CLUTCH DRUM


AT08035E01

  1. Using a dial indicator, measure the inside diameter of the clutch drum bushes.

    Maximum inside diameter:
    27.11 mm (1.0673 in.)

    If the inside diameter is greater than the maximum, replace the clutch drum.



4. INSPECT PISTON STROKE OF OVERDRIVE DIRECT CLUTCH


AT08140E01

  1. Place the oil pump onto the torque converter clutch, and then place the overdrive direct clutch drum assembly onto the oil pump.



    AT04448E01

  1. Using SST and a dial indicator, measure the overdrive direct clutch piston stroke while applying and releasing compressed air (392 kPa (4.0 kgf/cm2, 57 psi)).

    SST
    09350-30020   (09350-06120)

    Piston stroke:
    1.85 to 2.15 mm (0.0728 to 0.0846 in.)

    If the stroke is not as specified, inspect the discs.



5. REMOVE OVERDRIVE DIRECT CLUTCH DISC


AT08131E01

  1. Using a screwdriver, pry out the snap ring from the overdrive direct clutch drum.

  1. Remove the flange, 2 plates and 2 discs.



6. INSPECT OVERDRIVE DIRECT CLUTCH DISC


AT06455E01

  1. Replace all discs if one of the following problems is present: 1) a disc, plate or flange is worn or burnt, 2) the lining of a disc is peeled off or discolored, or 3) grooves or printed numbers have even a little bit of damage.

    HINT:
    Before assembling new discs, soak them in ATF for at least 15 minutes.



7. REMOVE OVERDRIVE DIRECT CLUTCH RETURN SPRING


AT08132E01

  1. Place SST on the spring retainer, and compress the return spring with a press.

    SST
    09350-30020   (09350-07040)

    NOTICE:
    Do not deform the spring sheet. Stop compressing when the spring sheet is lowered to 1 to 2 mm (0.039 to 0.078 in.) from the snap ring groove.

  1. Using snap ring pliers, remove the snap ring.

  1. Remove the piston return spring.



8. INSPECT OVERDRIVE DIRECT CLUTCH RETURN SPRING


D001246E02

  1. Using a vernier caliper, measure the free length of the spring together with the spring seat.

    Standard free length:
    15.8 mm (0.622 in.)

    If the length is not as specified, replace the spring.



9. REMOVE OVERDRIVE DIRECT CLUTCH PISTON


AT03151E01

  1. Place the oil pump onto the torque converter clutch, and then place the overdrive direct clutch onto the oil pump.

  1. Hold the overdrive direct clutch piston by hand, and apply compressed air (392 kPa (4.0 kgf/cm2, 57 psi)) to the oil pump to remove the overdrive direct clutch piston.

  1. Remove the overdrive direct clutch piston.

    HINT:
    If the piston is at an angle and cannot be removed, press down on the protruding side and apply compressed air again. Or, wind vinyl tape around the piston end and remove it with needle-nose pliers.

  1. Remove the 2 O-rings from the piston.



10. INSPECT OVERDRIVE DIRECT CLUTCH PISTON


AT08150E01

  1. Check that the check ball is free by shaking the piston.

  1. Check that the valve does not have leaks by applying low-pressure compressed air.



11. REMOVE OVERDRIVE PLANETARY RING GEAR FLANGE


AT08133E01

  1. Using a screwdriver, pry out the snap ring.



    AT08134E01

  1. Remove the ring gear flange.



12. REMOVE OVERDRIVE RETAINING PLATE


AT08135E01

  1. Using a screwdriver, pry out the snap ring.



    AT08146E01

  1. Remove the retaining plate.



13. REMOVE OVERDRIVE ONE-WAY CLUTCH OUTER RACE


AT08147E01


14. REMOVE OVERDRIVE ONE-WAY CLUTCH


AT04449E01

  1. Using a screwdriver, pry out the snap ring.

  1. Remove the retaining plate.



15. REMOVE NO.3 OVERDRIVE PLANETARY GEAR THRUST WASHER


AT08148E01


16. INSPECT OVERDRIVE PLANETARY GEAR


AT08143E01

  1. Using a dial indicator, measure the inside diameter of the planetary gear bush.

    Maximum inside diameter:
    11.27 mm (0.4437 in.)

    If the inside diameter is greater than the maximum, replace the planetary gear.



    AT04450E01

  1. Using a feeler gauge, measure the planetary pinion gear thrust clearance.

    Standard clearance:
    0.20 to 0.60 mm (0.0079 to 0.0236 in.)

    Maximum clearance:
    0.65 mm (0.0256 in.)

    If the clearance is greater than the maximum, replace the planetary gear.
