Check for a clogged orifice in the separator plate. If
the orifice is clogged, remove it and clean the
separator plate orifice.
Check the ATF level, and drain the ATF if it is over-
filled.
Check the ATF strainer for debris. If the ATF
strainer is clogged with particles of steel or
aluminum, inspect the ATF pump. If the ATF pump
is OK, find the damaged components that caused
the debris. If no cause for contamination is found,
replace the torque converter.
Check the 1st, 2nd, 3rd, 4th, and 5th clutch
pressures.
Check the relief valve in the main valve body for
free movement, and check the relief valve spring
for wear and damage.
Inspect the clutch piston, the clutch piston check
valve, and the O-rings. Check the spring retainer
and the retainer seal (for 1st, 2nd, and 3rd clutch
only) for wear, damage, and peeling. Inspect the
clearance between the clutch end-plate and the top
disc. If the clearance is out of tolerance, inspect the
clutch discs and the plates for wear and damage. If
the discs are worn or damaged, replace them as a
set. Inspect the clutch wave-plate height. If the
height is out of tolerance, replace the wave-plate. If
the discs and the plates are OK, adjust the
clearance with the clutch end-plate.
Inspect the 1st clutch feed pipe. If the 1st clutch
feed pipe is scored, replace the end cover.
Inspect the 3rd clutch feed pipe. If the 3rd clutch
feed pipe is scored, replace it and the O-ring under
the feed pipe guide.
Replace the secondary shaft if the bushing for the
1st or the 3rd clutch feed pipe is loose or damaged.
Inspect the 5th clutch feed pipe. If the 5th clutch
feed pipe is scored, replace it and the O-ring under
the feed pipe guide.
Replace the mainshaft if the bushing for the 5th
clutch feed pipe is loose or damaged.
