Dodge Durango (DN). Manual — part 69

(1) Raise vehicle.
(2) Loosen band adjusting screw locknut (Fig. 309).

Then back locknut off 3-5 turns. Be sure adjusting
screw turns freely in case. Apply lubricant to screw
threads if necessary.

(3) Tighten band adjusting screw to 8 N·m (72 in.

CAUTION: If Adapter C-3705 is needed to reach the
adjusting screw, tighten the screw to only 5 N·m
(47-50 in. lbs.) torque.

42RE TRANSMISSION

• Back off front band adjusting screw 3 turns.

• Hold adjuster screw in position and tighten lock-

nut to 41 N·m (30 ft. lbs.) torque.

44RE TRANSMISSION

• Back off front band adjusting screw 1-7/8 turns.

• Hold adjuster screw in position and tighten lock-

nut to 41 N·m (30 ft. lbs.) torque.

(4) Lower vehicle.

REAR BAND ADJUSTMENT

The transmission oil pan must be removed for

access to the rear band adjusting screw.

(1) Raise vehicle.
(2) Remove transmission oil pan and drain fluid.
(3) Loosen band adjusting screw locknut 5-6 turns

(Fig. 310). Be sure adjusting screw turns freely in
lever.

(4) Tighten adjusting screw to 8 N·m (72 in. lbs.)

torque.

42/44RE TRANSMISSION

• Back off adjusting screw 4 turns.

• Hold adjusting screw in place and tighten lock-

nut to 34 N·m (25 ft. lbs.) torque.

(5) Position new gasket on oil pan and install pan

on transmission. Tighten pan bolts to 17 N·m (13 ft.
lbs.) torque.

(6) Lower vehicle and refill transmission with

ADJUSTMENTS (Continued)

• Line Pressure

• Throttle Pressure
Line and throttle pressures are interdependent

because each affects shift quality and timing. As a
result, both adjustments must be performed properly
and in the correct sequence. Adjust line pressure first
and throttle pressure last.

LINE PRESSURE ADJUSTMENT

Measure distance from the valve body to the inner

edge of the adjusting screw with an accurate steel
scale (Fig. 311).

Distance should be 33.4 mm (1-5/16 in.).
If adjustment is required, turn the adjusting screw

in, or out, to obtain required distance setting.

NOTE: The 33.4 mm (1-5/16 in.) setting is an
approximate setting. Manufacturing tolerances may
make it necessary to vary from this dimension to
obtain desired pressure.

One complete turn of the adjusting screw changes

line pressure approximately 1-2/3 psi (9 kPa).

Turning

the

adjusting

screw

counterclockwise

increases pressure while turning the screw clockwise
decreases pressure.

THROTTLE PRESSURE ADJUSTMENT

Insert Gauge Tool C-3763 between the throttle

lever cam and the kickdown valve stem (Fig. 312).

Push the gauge tool inward to compress the kick-

down valve against the spring and bottom the throt-
tle valve.

Maintain pressure against kickdown valve spring.

Turn throttle lever stop screw until the screw head
touches throttle lever tang and the throttle lever cam
touches gauge tool.

NOTE: The kickdown valve spring must be fully
compressed and the kickdown valve completely
bottomed to obtain correct adjustment.
