(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:
REVERSE CLUTCH SNAP RING THICKNESS
4377195 1.53-1.58 mm (0.060-0.062 in.)
4412871 1.77-1.83 mm (0.070-0.072 in.)

4412873 2.27-2.32 mm (0.090-0.091 in.) (36) To complete the assembly, reverse clutch and
overdrive clutch must be removed. (37) Install the #2 needle bearing (Fig. 249).
(38) Install the underdrive shaft assembly (Fig.
250).

(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).
(42) Reinstall overdrive and reverse clutch as
shown. Rechecking these clutch clearances is
not necessary.

(22) Remove #4 thrust plate (Fig. 22).
(23) Remove front sun gear assembly and #4
thrust washer (Fig. 23). (24) Remove front carrier/rear annulus assembly
and #6 needle bearing (Fig. 24).
(25) Remove rear sun gear and #7 needle bearing
(Fig. 25).
NOTE: The number 7 needle bearing has three anti-
reversal tabs and is common with the number five
and number two position. The orientation should
allow the bearing to seat flat against the rear sun
gear (Fig. 26). A small amount of petrolatum can be
used to hold the bearing to the rear sun gear.
