Dodge Dakota (R1). Manual — part 673
INSTALLATION
(1) Snap the cable into the transmission bracket so
the retaining ears are engaged and snap the cable
eyelet onto the manual control lever ball stud.
(2) Lower vehicle.
(3) Route cable through hole in dash panel (Fig.
109) or (Fig. 110).
(4) Seat the cable mounting bracket to dash panel
and install retaining nuts to hold the cable housing
bracket to the dash panel.
(5) Tighten the nuts to 34 N·m (25 ft.lbs.).
(6) Place the transmission manual shift lever in
the “PARK” detent (rearmost) position and rotate
prop shaft to ensure transmission is in PARK.
(7) Connect shift cable to the steering column shift
lever (Fig. 111) by snapping the cable retaining ears
into shifter bracket and snapping the cable eyelet on
the steering column ball stud.
(8) Lock the shift cable adjustment by pressing the
cable adjuster lock upward until it snaps into place.
(9) Check for proper operation of the transmission
range sensor.
(10) Adjust the gearshift cable as necessary.

ADJUSTMENTS - GEARSHIFT CABLE
Check adjustment by starting the engine in PARK
and NEUTRAL. Adjustment is CORRECT if the engine
starts only in these positions. Adjustment is INCOR-
RECT if the engine starts in one but not both posi-
tions. If the engine starts in any position other than
PARK or NEUTRAL, or if the engine will not start at
all, the transmission range sensor may be faulty.
Gearshift Adjustment Procedure
(1) Shift transmission into PARK.
(2) Release cable adjuster lock tab (underneath the
steering column) (Fig. 112) 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
OIL PUMP
DESCRIPTION
The oil pump (Fig. 113) is located in the pump
housing inside the bell housing of the transmission
case. The oil pump consists of an inner and outer
gear, a housing, and a reaction shaft support.
OPERATION
As the torque converter rotates, the converter hub
rotates the inner and outer gears. As the gears
rotate,
the
clearance
between
the
gear
teeth
increases in the crescent area, and creates a suction
at the inlet side of the pump. This suction draws
fluid through the pump inlet from the oil pan. As the
clearance between the gear teeth in the crescent area
decreases, it forces pressurized fluid into the pump
outlet and to the valve body.
STANDARD PROCEDURE - OIL PUMP VOLUME
CHECK
Measuring the oil pump output volume will deter-
mine if sufficient oil flow to the transmission oil
cooler exists, and whether or not an internal trans-
mission failure is present.
Verify that the transmission fluid is at the proper
level. Refer to the Fluid Level Check procedure in
this section. If necessary, fill the transmission to the
proper level with Mopar
t ATF +4, type 9602, Auto-
matic Transmission Fluid.
(1) Disconnect the To cooler line at the cooler
inlet and place a collecting container under the dis-
connected line.
CAUTION: With the fluid set at the proper level,
fluid collection should not exceed (1) quart or inter-
nal damage to the transmission may occur.
(2) Run the engine at curb idle speed, with the
shift selector in neutral.
(3) If one quart of transmission fluid is collected in
the container in 20 seconds or less, oil pump flow vol-
ume is within acceptable limits. If fluid flow is inter-
mittent, or it takes more than 20 seconds to collect
one quart of fluid, refer to the Hydraulic Pressure
tests in this section for further diagnosis.
(4) Re-connect the To cooler line to the transmis-
sion cooler inlet.
(5) Refill the transmission to proper level.

DISASSEMBLY
(1) Mark position of support in oil pump body for
assembly alignment reference. Use scriber or paint to
make alignment marks.
(2) Place pump body on two wood blocks.
(3) Remove reaction shaft support bolts and sepa-
rate support from pump body (Fig. 114).
(4) Remove pump inner and outer gears (Fig. 115).
(5) Remove o-ring seal from pump body (Fig. 116).
Discard seal after removal.
(6) Remove oil pump seal with Remover Tool
C-3981. Discard seal after removal.
OIL PUMP BUSHING REMOVAL
(1) Position pump housing on clean, smooth sur-
face with gear cavity facing down.
(2) Remove bushing with Tool Handle C-4171 and
Bushing Remover SP-3550 (Fig. 117).
REACTION SHAFT SUPPORT BUSHING REMOVAL
(1) Assemble Cup Tool SP-3633, Nut SP-1191 and
Bushing Remover SP-5301 (Fig. 118).
(2) Hold cup tool firmly against reaction shaft.
Thread remover tool into bushing as far as possible
by hand.
(3) Using wrench, thread remover tool an addi-
tional 3-4 turns into bushing to firmly engage tool.
(4) Tighten tool hex nut against cup tool to pull
bushing from shaft. Clean all chips from shaft and
support after bushing removal.
