15. Check piston stroke of OD direct clutch (C–0)
Place the oil pump onto the torque converter, and
then place the OD direct clutch assembly onto the
oil pump.
25 2L10 0005Using a dial indicator, measure the OD direct clutch
piston stroke by applying and releasing the
compressed air (390 – 780 kPa or 57 – 114 psi) as
shown.
Piston stroke: 1.85 – 2.15 mm (0.0729 – 0.0847 in)
If the piston stroke is not within specification,
replace the disc and recheck the piston stroke.
If the piston stroke is nonstandard, select another
flange.

1. One-way clutch test.
The clutch should lock when turned
counterclockwise, and rotate freely and smoothly
clockwise. Less than 2.5 N·cm (22 Ib in) of torque
should be required to rotate the clutch clockwise. If
necessary, clean the converter and retest the clutch.
Replace the converter if the clutch still fails the test.
