  1. INSPECT OVERDRIVE ONE WAY CLUTCH


    1. A01BBGKE03

      Hold the O/D direct clutch drum, and turn the input shaft. Check that the input shaft can be turned freely clockwise and locked counterclockwise.

  2. INSPECT OVERDRIVE DIRECT CLUTCH DRUM SUB-ASSEMBLY


    1. A01BCIU

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

      Maximum inside diameter
      27.11 mm (1.0673 in.)

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

  3. INSPECT OVERDRIVE DIRECT CLUTCH CLUTCH DISC


    1. A01BEO2E02

      Check to see if the sliding surfaces of the disc, the plate and the flange are worn or burnt. If necessary, replace them.

      Tech Tips


      • If the lining of the disc is peeled off or discolored, or even if only a part of the printed numbers is corroded, replace all discs.

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

  4. INSPECT OVERDRIVE CLUTCH RETURN SPRING SUB-ASSEMBLY


    1. A01BEME

      Measure the free length of the spring together with the spring seat.

      Standard free length
      15.8 mm (0.622 in.)

  5. INSPECT OVERDRIVE DIRECT CLUTCH PISTON SUB-ASSEMBLY


    1. A01BFOJ

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

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

  6. INSPECT OVERDRIVE PLANETARY GEAR ASSEMBLY


    1. A01BBAG

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

      Maximum inside diameter
      11.27 mm (0.4437 in.)

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

    2. A01BH4J

      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 assembly.

  7. INSPECT PISTON STROKE OF OVERDRIVE DIRECT CLUTCH


    1. A01BH4Z

      Place the oil pump onto the torque converter clutch, and then place the O/D direct clutch assembly onto the oil pump.

    2. A01BBOYE03

      Using SST and a dial indicator, measure the O/D 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 piston stroke is less than the limit, parts may have been assembled incorrectly, so check and reassemble again.

      If the piston stroke is outside the standard, select another flange.

      Tech Tips

      There are 8 different thicknesses for the flange.

      Flange thickness
      No. Thickness No. Thickness
      08 3.8 mm (0.150 in.) 04 3.4 mm (0.134 in.)
      07 3.7 mm (0.146 in.) 03 3.3 mm (0.130 in.)
      06 3.6 mm (0.142 in.) 02 3.2 mm (0.126 in.)
      05 3.5 mm (0.138 in.) 01 3.1 mm (0.122 in.)
