debris. If no cause for the
contamination is found,
replace the torque converter.

Inspect the reverse selector
gear teeth chamfers, and
inspect the engagement teeth
chamfers of the countershaft
5th gear and the reverse gear.
Replace the reverse gears and
the reverse selector if they are
worn or damaged. If the
transmission makes clicking,
grinding, or whirring noises,
also replace the mainshaft 5th
gear, reverse idler gear, and
the countershaft 5th gear.

Inspect the clutch piston,
clutch piston check valve, and
the O-rings. Check the spring
retainer for wear and damage.
Inspect the clearance between
the clutch end-plate and the
top disc. If the clearance is out
of tolerance, inspect the clutch
discs and plates for wear and
damage, and inspect the
clutch wave-plate height. If
the discs and the flat-plates
are worn or damaged, replace
the discs and the flat-plates as
a set. If the wave-plate height
is out of tolerance, replace the
wave-plate. If the discs and
plates are OK, adjust the
clearance with the clutch end-
plate.

Poor acceleration; flares when
starting off in D and R; stall
speed high in R

1. Low ATF level

2. Shift cable broken or out of

adjustment

3. ATF pump worn or binding

4. Regulator valve stuck or

spring worn

5. ATF strainer clogged

6. Torque converter check

valve defective

Check the ATF level and
check the ATF cooler lines for
leakage and loose
connections. If necessary,
clean the ATF cooler lines.

Check for a loose shift cable
at the shift lever and the
transmission control lever.

Check the line pressure.

Check the ATF strainer for
debris. If the strainer is
clogged, find the damaged
components that caused the
debris.

Improper alignment of the
ATF pump and the torque
converter housing may cause
the ATF pump seizure. The
symptom is mostly an rpm-
related ticking noise or a high
pitched squeak.

Be careful not to damage the
torque converter housing
when replacing the main ball
bearing. You may also
damage the ATF pump when
you torque down the main
valve body. This will result in
the ATF pump seizure if not
detected. Use the proper tools.

Poor acceleration; flares when
starting off in D, D3, and R; stall
speed high in D and D3

1. 1st accumulator defective

2. 1st clutch defective

Check the 1st clutch pressure.

Inspect the clutch piston,
clutch piston check valve, and
the O-rings. Check the spring
retainer for wear and damage.
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, and inspect the
clutch wave-plate height. If
the discs and the flat-plates
are worn or damaged, replace
the discs and the flat-plates as
a set. If the wave-plate 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.
