(6) Inspect the ends of the sensors for debris,
which may indicate the nature of the transmission
failure.
(7) Install Support Stand 8257 onto the transmis-
sion case (Fig. 16).
(8) Using Adapter 8266-1 from End-Play Tool Set
8266 and Dial Indicator C-3339, measure and record
the input shaft end-play (Fig. 17).
NOTE: When measuring the input shaft end-play,
two(stops(will be felt. When the input shaft is
pushed inward and the dial indicator zeroed, the
first(stop(felt when the input shaft is pulled out-
ward is the movement of the input shaft in the inputclutch housing hub. This value should not be
included in the end-play measured value and there-
fore must be recorded and subtracted from the dial
indicator reading.
(9) Remove the bolts holding the transmission
extension/adapter housing to the transmission case.
(10) Remove the extension/adapter housing from
the transmission case.
(11) Using Alignment Plate 8261, Adapter 8266-17
from End-Play Tool Set 8266 and Dial Indicator
C-3339, measure and record the output shaft end-
play (Fig. 18).
(12) Remove the bolts holding the transmission oil
pan to the transmission case.
(13) Remove the transmission oil pan from the
transmission case.
(14) Remove the primary oil filter and the oil
cooler return filter (Fig. 19).
(15) Remove the cooler return filter bypass valve.
(16) Remove the bolts holding the valve body to
the transmission case (Fig. 20).
(17) Remove the valve body from the transmission
case.
(18) Remove the outer snap-ring securing the
transmission front cover into the transmission case
(Fig. 21).
(19) Remove the inner snap-ring securing the
transmission front cover to the oil pump (Fig. 21).
(20) Reaching through a case opening in the valve
body area with a long blunted tool, remove the trans-
mission front cover from the transmission case.
(21) Remove the bolts holding the oil pump into
the transmission case (Fig. 22).

(9) Install a new dipstick tube seal using Seal
Installer 8254 (Fig. 34).
NOTE: Before final assembly of transmission cen-
terline, the 2C/4C clutch components should be
installed into position and measured as follows:
(10) Install the 2C reaction plate into the trans-
mission case (Fig. 35). The reaction plate is direc-
tional. The plate must be installed with the flat side
toward the front of the transmission.
(11) Install the 2C clutch pack into the transmis-
sion case (Fig. 35).
(12) Install the flat 2C clutch snap-ring into the
transmission case (Fig. 35).
(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. The correct clutch clearance is 0.455-
1.335 mm (0.018-0.053 in.). The reaction plate is not
selective. If the clutch pack clearance is not within
specification, the reaction plate, all the friction discs,
and steels must be replaced.
(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.
36). 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. 36).
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.
