tow CHRYSLER VOYAGER 2001 Service Manual

NOTE: Power steering pump maximum relief pres-
sure is 9,653 to 10,342 kPa (1,400 to 1,500 psi.).
(9) Close analyzer valve fully three times and
record highest pressure indicated each time. All three
readings must be above specifications and within 345
kPa (50 psi) of each other.
²If power steering pump pressures are above
specifications, but not within 345 kPa (50 psi) of each
other, replace pump.
²If power steering pump pressures are within 345
kPa (50 psi) of each other, but are below specifica-
tions, replace pump.
CAUTION: Do not force the pump to operate against
the stops for more than 2 to 4 seconds at a time
because, pump damage will result.
(10) Completely open the valve on the Power
Steering Analyzer. Turn the steering wheel to theextreme left until the stop in the steering gear is
met, then turn the steering wheel to the right until
the right stop is met. Record the highest indicated
pressure at each position. Compare the recorded
readings to the specifications. If the highest output
pressures are not the same against either stop, the
steering gear is leaking internally and must be
replaced.

INSTALLATION
The power transfer unit input shaft cover seal is
the larger of the two seals located on the inside of
the end cover. The differential bearing cup must be
removed to service this seal.
(1) Clean and inspect seal area.
(2) Use special tool No. MD998803 and install seal
(Fig. 34). When installing seal the spring side of the
seal must face toward the special tool.
(3) Reinstall the original bearing race and shim
using special tool No. 6522 (Fig. 35) and (Fig. 36).

CLEANING
Clean the servo piston components (Fig. 201) with
solvent and dry them with compressed air. Wipe the
band clean with lint free shop towels.
Replace the front band if distorted, lining is
burned, flaking off, or worn to the point where the
grooves in the lining material are no longer visible.
Replace any servo component if doubt exists about
condition. Do not reuse suspect parts.
INSPECTION
Inspect the servo components (Fig. 202). Replace
the springs if collapsed, distorted or broken. Replace
the guide, rod and piston if cracked, bent, or worn.
Discard the servo snap-ring if distorted or warped.
Check the servo piston bore for wear. If the bore is
severely scored, or damaged, it will be necessary to
replace the case.

A conventional mechanical interlock system is also
used. This system manually prohibits shifter move-
ment when the ignition switch is in the LOCK or
ACC positions. Solenoid operation is not required in
these key positions. When the ignition key is in the
OFF position, the gearshift lever is unrestricted, and
able to move into any gear position (during towing,
dead battery, etc.).
For intended BTSI system operation, refer to the
following chart:

OPERATION
The converter impeller (Fig. 235) (driving member),
which is integral to the converter housing and bolted
to the engine drive plate, rotates at engine speed.
The converter turbine (driven member), which reacts
from fluid pressure generated by the impeller, rotates
and turns the transmission input shaft.
TURBINE
As the fluid that was put into motion by the impel-
ler blades strikes the blades of the turbine, some of
the energy and rotational force is transferred into the
turbine and the input shaft. This causes both of them
(turbine and input shaft) to rotate in a clockwise
direction following the impeller. As the fluid is leav-
ing the trailing edges of the turbine's blades it con-
tinues in a ªhinderingº direction back toward the
impeller. If the fluid is not redirected before it strikes
the impeller, it will strike the impeller in such a
direction that it would tend to slow it down.

CLEANING
Clean the valve body components in a parts clean-
ing solution only. Do not use gasoline, kerosene, or
any type of caustic solution. Dry the parts with com-
pressed air. Make sure all passages are clean and
free from obstructions.
NOTE: Do not use rags or shop towels to wipe off
valve body components. Lint from these materials
will adhere to the valve body components. Lint will
interfere with valve operation and may clog filters
and fluid passages.
Minor distortion of a valve body mating surface
may be corrected by smoothing the surface with cro-
cus cloth. The cloth should be in sheet form and be
positioned on a surface plate, sheet of plate glass, or
equally flat surface. However, if distortion is severeor any surfaces are heavily scored, the valve body
will have to be replaced.
CAUTION: Many of the valve body valves and plugs
are made of coated aluminum. Aluminum compo-
nents can be identified by the dark color of the spe-
cial coating applied to the surface (or by testing
with a magnet). DO NOT polish or sand aluminum
valves or plugs with any type of material, or under
any circumstances. This practice might damage the
special coating and cause the valves and plugs to
stick and bind.
Aluminum valves and plugs should not be sanded
or polished under any circumstances. However, minor
burrs or scratches on steel valves and plugs can be
removed with crocus cloth but do not round off the
valve or plug edges. Squareness of these edges is

(25) Measure OD clutch pack clearance. Set up
dial indicator on top of the OD/Reverse reaction plate
as shown in (Fig. 283).
(26) Zero dial indicator and apply 30 psi (206 kPa)
air pressure to the overdrive clutch hose on Tool
8391. Measure and record OD clutch pack measure-
ment in four (4) places, 90É apart.
(27) Take average of four measurements and com-
pare with OD clutch pack clearance specification.
The overdrive (OD) clutch pack clearance is
1.07-3.25 mm (0.042-0.128 in.).
If not within specifications, the clutch is not
assembled properly. There is no adjustment for the
OD clutch clearance.

(32) Set up a dial indicator on the reverse clutch
pack as shown in (Fig. 288).
(33) Using moderate pressure, press down and
hold (near indicator) reverse clutch disc with screw-
driver or suitable tool and zero dial indicator (Fig.
