Overdrive Direct Clutch Inspection

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.

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

Maximum inside diameter:

27.11 mm (1.0673 in.)

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

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.)

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.

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.)

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

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

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

Maximum inside diameter:

11.27 mm (0.4437 in.)

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

Standard clearance:

0.20 to 0.60 mm (0.00787 to 0.0236 in.)

Maximum clearance:

0.65 mm (0.0256 in.)
