Dodge Dakota (R1). Manual — part 712
Gearshift Adjustment Procedure
(1) Shift transmission into PARK.
(2) Release cable adjuster lock tab (underneath the
steering column) (Fig. 63) to unlock cable.
(3) Raise vehicle.
(4) Disengage the cable eyelet from the transmis-
sion manual shift lever.
(5) Verify transmission shift lever is in PARK
detent by moving lever fully rearward. Last rearward
detent is PARK position.
(6) Verify positive engagement of transmission
park lock by attempting to rotate propeller shaft.
Shaft will not rotate when park lock is engaged.
(7) Snap the cable eyelet onto the transmission
manual shift lever.
(8) Lower vehicle.
(9) Lock shift cable by pressing cable adjuster lock
tab upward until it snaps into place.
(10) Check engine starting. Engine should start
only in PARK and NEUTRAL
HOLDING CLUTCHES
DESCRIPTION
Three hydraulically applied multi-disc clutches are
used to hold some planetary geartrain components
stationary while the input clutches drive others. The
2C, 4C, and Low/Reverse clutches are considered
holding clutches. The 2C and 4C clutches are located
in the 4C retainer/bulkhead (Fig. 64), while the Low/
Reverse clutch is located at the rear of the transmis-
sion case (Fig. 65).
OPERATION
2C CLUTCH
The 2C clutch is hydraulically applied in second
gear by pressurized fluid against the 2C piston.
When the 2C clutch is applied, the reverse sun gear
assembly is held or grounded to the transmission
case by holding the reaction planetary carrier.
4C CLUTCH
The 4C clutch is hydraulically applied in second
prime and fourth gear by pressurized fluid against
the 4C clutch piston. When the 4C clutch is applied,
the reaction annulus gear is held or grounded to the
transmission case.
LOW/REVERSE CLUTCH
The Low/Reverse clutch is hydraulically applied in
park, reverse, neutral, and first gear, only at low
speeds, by pressurized fluid against the Low/Reverse
clutch piston. When the Low/Reverse clutch is
applied, the input annulus assembly is held or
grounded to the transmission case.

INPUT CLUTCH ASSEMBLY
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. 66) and (Fig. 67). 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.
UNDERDRIVE CLUTCH
The underdrive clutch is hydraulically applied in
first, second, second prime, and third (direct) gears
by pressurized fluid against the underdrive piston.
When the underdrive clutch is applied, the under-
drive hub drives the input sun gear.
