(42) Reinstall overdrive and reverse clutch as
shown. Rechecking these clutch clearances is
not necessary.
OIL PUMP
DESCRIPTION
The oil pump is located in the pump housing inside
the bell housing of the transaxle case (Fig. 274). The
oil pump consists of an inner and outer gear, a hous-
ing, and a cover that also serves as the reaction shaft
support.
OPERATION
As the torque converter rotates, the converter hub
rotates the inner and outer gears. As the gears
rotate,
the
clearance
between
the
gear
teeth
increases in the crescent area, and creates a suction
at the inlet side of the pump. This suction draws
fluid through the pump inlet from the oil pan. As the
clearance between the gear teeth in the crescent area
decreases, it forces pressurized fluid into the pump
outlet and to the valve body.

DISASSEMBLY
When disassembling the transaxle it is necessary
to inspect the oil pump for wear and damage.
(1) Remove the reaction shaft support-to-pump
body bolts (Fig. 275).
(2) Remove reaction shaft support from pump
housing (Fig. 276).
(3) Remove the pump gears (Fig. 277) and check
for wear and damage on pump housing and gears.
(4) Re-install the gears and check clearances.
(5) Measure the clearance between the outer gear
and the pump pocket (Fig. 278). Clearance should be
0.089–0.202 mm (0.0035-0.0079 in.).

(6) Measure clearance between outer gear and
crescent (Fig. 279). Clearance should be 0.060-0.298
mm (0.0023-0.0117 in.).
(7) Measure clearance between inner gear and
crescent (Fig. 280). Clearance should be 0.093-0.385
mm (0.0036-0.0151 in.).
(8) Position an appropriate piece of Plastigage
across both pump gears.
(9) Align the Plastigage to a flat area on the reac-
tion shaft support housing.
(10) Install the reaction shaft to the pump housing
(Fig. 275). Tighten the bolts to 27 N·m (20 ft. lbs.).
(11) Remove bolts and carefully separate the hous-
ings. Measure the Plastigage following the instruc-
tions supplied.
(12) Clearance between both gear end faces and
the reaction shaft support should be 0.020-0.046 mm
(0.0008-0.0018 in.).

ASSEMBLY
(1) Assemble oil pump as shown in (Fig. 281).
(2) Install and torque reaction shaft support-to-oil
pump housing bolts to 28 N·m (20 ft. lbs.) torque
(Fig. 282).
PLANETARY GEARTRAIN
DESCRIPTION
The planetary geartrain is located between the
input clutch assembly and the rear of the transaxle
case. The planetary geartrain consists of two sun
gears, two planetary carriers, two annulus (ring)
gears, and one output shaft (Fig. 283).
OPERATION
The planetary geartrain utilizes two planetary gear
sets that connect the transmission input shaft to the
output shaft. Input and holding clutches drive or lock
different planetary members to change output ratio
or direction.

REMOVAL
(1) Remove transaxle from vehicle (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC - 41TE
- REMOVAL).
(2) Using Tool C-3981-B, remove oil pump seal
(Fig. 284).
