DRIVING CLUTCHES
DESCRIPTION
Three hydraulically applied input clutches are used
to drive planetary components. The underdrive, over-
drive, and reverse clutches are considered input
clutches and are contained within the input clutch
assembly (Fig. 167). The input clutch assembly also
contains:
²Input shaft
²Input hub
²Clutch retainer
²Underdrive piston
²Overdrive/reverse piston
²Overdrive hub
²Underdrive hub
OPERATION
The three input clutches are responsible for driving
different components of the planetary geartrain.
NOTE: Refer to the ªElements In Useº chart in Diag-
nosis and Testing for a collective view of which
clutch elements are applied at each position of the
selector lever.
UNDERDRIVE CLUTCH
The underdrive clutch is hydraulically applied in
first, second, and third (direct) gears by pressurized
fluid against the underdrive piston. When the under-
drive clutch is applied, the underdrive hub drives the
rear sun gear.
OVERDRIVE CLUTCH
The overdrive clutch is hydraulically applied in
third (direct) and overdrive gears by pressurized fluid
against the overdrive/reverse piston. When the over-
drive clutch is applied, the overdrive hub drives the
front planet carrier.
REVERSE CLUTCH
The reverse clutch is hydraulically applied in
reverse gear only by pressurized fluid against the
overdrive/reverse piston. When the reverse clutch is
applied, the front sun gear assembly is driven.
FINAL DRIVE
DESCRIPTION
The 4XTE differential is a conventional open
design. It consists of a ring gear and a differential
case. The differential case consists of pinion and side
gears, and a pinion shaft. The differential case is
supported in the transaxle by tapered roller bearings
(Fig. 168).

21 - 74 40TE AUTOMATIC TRANSAXLERS

OPERATION
The differential assembly is driven by the transfer
shaft by way of the differential ring gear. The ring
gear drives the differential case, and the case drives
the driveshafts through the differential gears. The
differential pinion and side gears are supported in
the case by thrust washers and a pinion shaft. Dif-
ferential pinion and side gears make it possible for
front tires to rotate at different speeds while corner-
ing.
DISASSEMBLY
NOTE: The differential is serviced as an assembly.
The only parts that are serviceable within the differ-
ential are the differential bearing cups and cones. If
any other part fails within the differential, you must
replace the differential assembly along with the
transfer shaft.
The transfer shaft should be removed for differen-
tial repair and bearing turning torque checking.
(1) Remove the differential cover and bolts (Fig.
169) (Fig. 170).(2) Remove the differential bearing retainer and
bolts (Fig. 171) (Fig. 172).

(3) Using a plastic hammer, remove extension
housing/adapter plate on the right side of the trans-
axle.
WARNING: HOLD ONTO DIFFERENTIAL ASSEMBLY
TO PREVENT IT FROM ROLLING OUT OF HOUSING.
(4) Remove differential assembly.
(5) Set up dial indicator set C-3339 and tool
C-4996 as shown in (Fig. 173) (Fig. 174) to measure
side gear end play.Side gear end play must be
within 0.001-0.013 in.(6) Use Miller Special Tool 5048, 5048-3 Collets,
and L-4539-2 Button to remove the differential bear-
ing cone on the extension housing side.

(8) Using Miller Special Tool L-4518, remove the
differential bearing race from the extension housing/
adapter plate.
