ADJUSTMENTS
ADJUSTMENT - BRAKE TRANSMISSION SHIFT
INTERLOCK CABLE
(1) Shift transmission into PARK.
(2) Remove shift lever bezel and console screws.
Raise bezel and console for access to cable.
(3) Pull cable lock button up to release cable.
(4) Turn ignition switch to LOCK position.
(5) Use a spacer to create a one millimeter gap
between the shifter pawl and top of the shift gate.
(6) Pull the cable forward and release.Ensure the
cable end is seated in the bellcrank and press cable
lock button down until it snaps in place.
(7) Check adjustment as follows:
(a) Check movement of release shift handle but-
ton (floor shift) or release lever (column shift). You
should not be able to press button inward or move
column lever.
(b) Turn ignition switch to RUN position.
(c) Shifting out of park should not be possible.
(d) Apply the brake and attempt to shift out of
PARK. Shifting should be possible.
(e) While the transmission is shifted out of
PARK, release the brake and attempt to shift
through all gears. Release the shift button at least
once during this procedure. The ignition key should
not go to the LOCK position.
(f) Return transmission to the PARK position
without applying the brake.
(8) Move shift lever back to PARK and check igni-
tion switch operation. You should be able to turn
switch to LOCK position and shift lever release but-
ton/lever should not move.
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. 153). The input clutch assembly also
contains:
• Input shaft
• Input hub
• Clutch retainer
• Underdrive piston
• Overdrive/reverse piston
• Overdrive hub
• Underdrive hub

OPERATION

The three input clutches are responsible for driving
different components of the planetary geartrain.

NOTE: (Refer to 21 - TRANSMISSION/AUTOMATIC -
42RLE - DIAGNOSIS 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.
