(25) Measure OD clutch pack clearance. Set up
dial indicator on top of the OD/Reverse pressure
plate as shown in (Fig. 241).
(26) Zero dial indicator and apply 30 psi (206 kPa)
air pressure to the overdrive clutch hose on Tool
8391. Measure and record OD clutch pack measure-
ment in four (4) places, 90É apart.
(27) Take average of four measurements and com-
pare with OD clutch pack clearance specification.
The overdrive (OD) clutch pack clearance is
1.07-3.25 mm (0.042-0.128 in.).
If not within specifications, the clutch is not
assembled properly. There is no adjustment for the
OD clutch clearance.

(32) Set up a dial indicator on the reverse clutch
pack as shown in (Fig. 247).
(33) Using moderate pressure, press down and
hold (near indicator) reverse clutch disc with screw-
driver or suitable tool and zero dial indicator (Fig.
248). When releasing pressure, indicator should
advance 0.005-0.010. as clutch pack relaxes.
(34) Apply 30 psi (206 kPa) air pressure to the
reverse clutch hose on Tool 8391. Measure and record
reverse clutch pack measurement in four (4) places,
90É apart.
(35) Take average of four measurements and com-
pare with reverse clutch pack clearance specification.
The reverse clutch pack clearance is 0.89-1.37
mm (0.035-0.054 in.).Select the proper reverse
clutch snap ring to achieve specifications:

(39) Install the #3 thrust washer to the underdrive
shaft assembly. Be sure five tabs are seated properly
(Fig. 251).(40) Install the #3 thrust plate to the bottom of the
overdrive shaft assembly. Retain with petrolatum or
transmission assembly gel (Fig. 252).
(41) Install the overdrive shaft assembly (Fig. 253)
(Fig. 254).

(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. 256). 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. 262).
(2) Install and torque reaction shaft support-to-oil
pump housing bolts to 28 N´m (20 ft. lbs.) torque
(Fig. 263).
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. 264).
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.
