DISASSEMBLY AND ASSEMBLY (Continued)
(39) Remove the input/reverse planetary assembly
(Fig. 67).
(40) Remove the number 12 bearing from the
input/reverse planetary assembly (Fig. 67).
(41) Remove the snap-ring holding the low/reverse
clutch retainer into the transmission case (Fig. 68).
(42) Remove the low/reverse clutch retainer from
the transmission case (Fig. 68).
(43) Remove the park pawl rod and e-clip (Fig. 69).
(44) Remove the park pawl rod guide snap-ring
(Fig. 69).
(45) Remove the park pawl rod guide (Fig. 69).
(46) Remove the park pawl pivot shaft, park pawl,
and spring (Fig. 69).
(47) Remove the manual selector shaft (Fig. 69).
(48) Remove the manual selector shaft seal.
(49) Remove the dipstick tube seal.
ASSEMBLY
(1) Clean and inspect all components. Replace any
components which show evidence of excessive wear
or scoring.
(2) Install the cooler filter bypass valve.
(3) Torque the bypass valve to specification. The
valve uses a tapered pipe thread and excessive
torque can damage the transmission case. Tighten
the cooler filter bypass valve to 11.3 N·m (100
in.lbs.).
(4) Install a new selector shaft seal using Seal
Installer 8253 (Fig. 70).
(5) Install the manual selector shaft and retaining
screw. Tighten the manual selector shaft retaining
screw to 28 N·m (250 in.lbs.).
(6) Install the park pawl, spring, and shaft (Fig.
69).
(7) Install the park rod and e-clip (Fig. 69).
(8) Install the park rod guide and snap-ring (Fig.
69).
(9) Install a new dipstick tube seal using Seal
Installer 8254 (Fig. 71).
NOTE: Before final assembly of transmission cen-
terline, the 2C/4C clutch components should be
installed into position and measured/adjusted as
follows:

DISASSEMBLY AND ASSEMBLY (Continued)
(10) Install the 2C reaction plate into the trans-
mission case (Fig. 63). The reaction plate is selective
and directional. The plate must be installed with the
flat side toward the front.
(11) Install the 2C clutch pack into the transmis-
sion case (Fig. 63).
(12) Install the flat 2C clutch snap-ring into the
transmission case (Fig. 63).
(13) Install the 4C retainer/bulkhead into the
transmission case. Make sure that the oil feed holes
are pointing toward the valve body area.
(14) Install
the
4C
retainer/bulkhead
tapered
snap-ring into the transmission case. Make sure that
the open ends of the snap-ring are located in the case
opening toward the valve body area.
(15) Using a feeler gauge through the opening in
the rear of the transmission case, measure the 2C
clutch pack clearance between the 2C reaction plate
and the transmission case at four different points.
The average of these measurements is the 2C clutch
pack clearance. Adjust the clearance as necessary.
The correct clutch clearance is 0.533–1.27 mm
(0.021–0.050 in.). The reaction plate is selective.
Install the chosen reaction plate and re-measure the
clutch clearance to verify the selection.
(16) Remove the 4C retainer/bulkhead and all of
the 2C clutch components from the transmission
case.
(17) Install the low/reverse clutch assembly (Fig.
72). Make sure that the oil feed hole points toward
the valve body area and that the bleed orifice is
aligned with the notch in the rear of the transmis-
sion case.
(18) Install the snap-ring to hold the low/reverse
clutch retainer into the transmission case (Fig. 72).
The snap-ring is tapered and must be installed with
the tapered side forward. Once installed, verify that
the snap-ring is fully seated in the snap-ring groove.
(19) Air check the low/reverse clutch and verify
correct overrunning clutch operation.
(20) Install the reverse/input planetary assembly
through the low/reverse clutch assembly (Fig. 73).
(21) Install the number 12 bearing over the output
shaft of the rear planetary gear set and onto the low/
reverse clutch assembly. The flat side of the bearing
goes toward the clutch assembly.
(22) Install the park sprag onto the output shaft
(Fig. 74).
(23) Install the snap-ring to hold the park sprag
onto the output shaft (Fig. 75).
(24) Install the 2C reaction plate into the trans-
mission case (Fig. 76). The reaction plate is selective
and directional. The plate must be installed with the
flat side toward the front.

DISASSEMBLY AND ASSEMBLY (Continued)
(25) Install the 2C clutch pack into the transmis-
sion case (Fig. 76).
(26) Install the number 8 bearing inside the reac-
tion carrier with the round side against the plane-
tary carrier.
(27) Install the reaction planetary gear set and the
number 9 bearing into the transmission case (Fig.
77).
(28) Install the flat 2C clutch snap-ring into the
transmission case (Fig. 76).
(29) Install the reaction sun gear into the reaction
planetary gear set with the small shoulder facing the
front of the transmission (Fig. 77).
(30) Install the number 7 bearing onto the reaction
sun gear with the flat side against the sun gear (Fig.
77).
(31) Install the output shaft selective thrust plate
onto the reaction annulus with the oil grooves facing
the annulus gear and the tabs and notches aligned as
shown in (Fig. 78).
(32) Install the number 6 bearing against the out-
put shaft selective spacer with the flat side against
the spacer (Fig. 77).
(33) Install the reaction annulus into the reaction
planetary gear set (Fig. 77).
(34) Install the 4C retainer/bulkhead into the
transmission case. Make sure that the oil feed holes
are pointing toward the valve body area. Rotate the
reaction annulus during the installation of the 4C
retainer/bulkhead to ease installation.
(35) Install
the
4C
retainer/bulkhead
tapered
snap-ring into the transmission case (Fig. 79). Make
