FLUID LEAKAGE-TORQUE CONVERTER
HOUSING AREA CHECK
(1) Check for source of leakage.Since fluid leakage at or around the torque convert er
area may originate from an engine oil leak, the area should
be examined closely, Factory fill fluid is dyed red and,
therefore, can be distinguished from engine oil.
(2) Before removing the transaxle, perform the foll owing
checks:
When leakage is determined to originate from the tr ans-
axle, check fluid level before removal of the transaxle
and torque converter.
High oil level can result in oil leakage out the vent in
the manual shaft. If the fluid level is high, adjust to
proper level.
After fluid is at the proper level, check for leakage. If
a leak
perform the following operation on the
to determine if it is the torque converter or tran saxle
that is, leaking.
TORQUE CONVERTER LEAKAGE
Possible sources of torque converter leakage are:
(2) Torque converter weld leaks at the out side (pe ripheral)
weld. Torque converter hub weld.
(3) Hub
inside and not visible. Do not attempt to
repair.
Replace torque converter.
If the torque converter must be replaced, refer to Torque
Converter Clutch Break-in Procedure in this section . This
procedure’ will reset the transaxle control module break-in
status. Failure to perform this procedure may cause transaxle
shutter.

HYDRAULIC PRESSURE TESTS
Pressure testing is a very important step in the diagnostic
procedure. These tests usually reveal the cause of most
transaxle problems.
Before performing pressure tests, be certain that fluid level
and condition, and shift cable adjustments have bee n checked
and approved.Fluid must be at operating temperature

1. Install an engine tachometer.
2.Raise vehicle on hoist which allows front wheels to
turn,
and position tachometer so it can be read.
3. Attach 1,000
(140 psi) gauge and special tool
to ports required for test being conducted.
A 3,000 (400 psi) gauge and special tool
are required for reverse pressure test. Test port l ocations
are shown in illustration.
