OVERDRIVE CLUTCH
Apply air pressure to the overdrive clutch apply
passage and watch for the push/pull piston to move
forward. The piston should return to its starting
position when the air pressure is removed.
REVERSE CLUTCH
Apply air pressure to the reverse clutch apply pas-
sage and watch for the push/pull piston to move rear-
ward. The piston should return to its starting
position when the air pressure is removed.
2/4 CLUTCH
Apply air pressure to the feed hole located on the
2/4 clutch retainer. Look in the area where the 2/4
piston contacts the first separator plate and watch
carefully for the 2/4 piston to move rearward. The
piston should return to its original position after the
air pressure is removed.
LOW/REVERSE CLUTCH
Apply air pressure to the low/reverse clutch feed
hole (rear of case, between 2 bolt holes). Then, look
in the area where the low/reverse piston contacts the
first separator plate. Watch carefully for the piston to
move forward. The piston should return to its origi-
nal position after the air pressure is removed.
UNDERDRIVE CLUTCH
Because this clutch piston cannot be seen, its oper-
ation is checked by function. Air pressure is applied
to the low/reverse and the 2/4 clutches. This locks the
output shaft. Use a piece of rubber hose wrapped
around the input shaft and a pair of clamp-on pliers
to turn the input shaft. Next apply air pressure to
the underdrive clutch. The input shaft should not
rotate with hand torque. Release the air pressure
and confirm that the input shaft will rotate.
FLUID LEAKAGE-TORQUE CONVERTER HOUSING
AREA
(1) Check for source of leakage.
(2) Fluid leakage at or around the torque converter
area may originate from an engine oil leak. The area
should be examined closely. Factory fill fluid is red
and, therefore, can be distinguished from engine oil.
(3) Prior to removing the transaxle, perform the
following checks:
(4) When leakage is determined to originate from
the transaxle, check fluid level prior to removal of
the transaxle and torque converter.
(5) 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.
(6) After performing this operation, inspect for
leakage. If a leak persists, perform the following
operation on the vehicle. This will determine if the
torque converter or transaxle is leaking.
TORQUE CONVERTER LEAKAGE
Possible sources of torque converter leakage are:
•
Torque converter weld leaks at the outside
(peripheral) weld.
•
Torque converter hub weld.
NOTE: Hub weld is inside and not visible. Do not
attempt to repair. Replace torque converter.
NOTE: If the torque converter must be replaced,
refer to Torque Converter Clutch Break-in Proce-
dure in this section. This procedure will reset the
transmission control module break-in status. Fail-
ure to perform this procedure may cause transaxle
shutter.
INTERLOCK SYSTEM OPERATION CHECK
(1) Place shifter in PARK, the Ignition switch
should rotate freely from OFF to LOCK position.
When the shifter is moved to the DRIVE position the
ignition switch should not rotate from OFF to LOCK.
(2) Moving the shifter out of PARK should only be
possible when the ignition switch is in the OFF or
RUN position. Movement of the shifter from the
PARK position should not be possible, when the igni-
tion switch is in the LOCK or ACCESSORY position.
(3) If the Interlock System, operates in any way
other than as described above, repair of the Interlock
System is required. See Adjustment and Repair pro-
cedures, in this section for the required procedures.
SHIFT POSITION INDICATOR
The transmission range sensor (on the valve body)
sends a signal to the TCM on the position of the
transaxle manual valve lever. The TCM receives the
