tow CHRYSLER VOYAGER 1996 Service Manual

Inspect all valve springs for distortion and col-
lapsed coils. Inspect all valves and plugs for burrs,
nicks, and scores. Small nicks and scores may be
removed with crocus cloth, providing extreme care is
taken not to round off sharp edges. The sharpness of
these edges is vitally important. It prevents foreign
matter from lodging between valve and valve body.
This reduces the possibility of sticking. Inspect all
valves and plugs for freedom of operation in valve
body bores.
When bores, valves, and plugs are clean and dry,
the valves and plugs should fall freely in the bores.
The valve body bores do not change its dimensions
with use. Therefore, a valve body that was function-
ing properly when vehicle was new, will operate cor-
rectly if it is properly and thoroughly cleaned. There
is no need to replace valve body unless it is damaged
in handling.
ADJUSTMENTS
GEARSHIFT CABLE ADJUSTMENT
Lift and rotate the gearshift hand lever into the
park (P) gate position and remove the ignition key.
This confirms the shift lever is in the gated park (P)
position.
After confirming the park gate position, turn the
ignition switch. If the starter will operate, the park
gate position is correct. Move the shift lever into the
neutral (N) position. If the starter will operate in this
position, the linkage is properly adjusted. If the
starter fails to operate in either position, linkage
adjustment is required.
(1) Park the vehicle on level ground and set the
parking brake.
(2) Place the gearshift lever in park (P) gate posi-
tion and remove key.
(3) Loosen the cable adjustment screw at the tran-
saxle operating lever (Fig. 160).
(4) Pull the transaxle operating lever fully forward
to the park detent position.
(5) Release the park brake, then rock the vehicle
to assure it is in park lock. Reset the park brake.
(6) Tighten the cable adjustment screw to 8 N´m
(70 in. lbs.). Gearshift cable should now be properly
adjusted.
(7) Verify PRNDL indicator still displays the corre-
sponding gear completely. If not, readjustment of
PRNDL may be required.
(8) Check adjustment by using the preceding pro-
cedure.
THROTTLE PRESSURE LINKAGE ADJUSTMENT
The throttle pressure rod adjustment is very
important to proper transaxle operation. This adjust-
ment positions a valve which controls shift speed,shift quality, and part throttle downshift sensitivity.
If the setting is too short, early shifts and slippage
between shifts may occur. If the setting is too long,
shifts may be delayed and part throttle downshifts
may be very sensitive.
With engine at operating temperature, adjust idle
speed of engine using a tachometer. Refer to Group
14, Fuel System for idle speed Specifications and
adjustment.
ROD ADJUSTMENT PROCEDURE
(1) Perform transaxle throttle pressure adjustment
while engine is at normal operating temperature.
(2) Loosen adjustment swivel lock screw.
(3) To insure proper adjustment, swivel must be
free to slide along flat end of throttle rod. Disassem-
ble and clean or repair parts to assure free action, if
necessary.
(4) Hold transaxle throttle lever firmly toward
engine, against its internal stop. Tighten swivel lock
screw to 11 N´m (100 in. lbs.)
(5) The adjustment is finished and linkage back-
lash was automatically removed by the preload
spring.
(6) I
f lubrication is required see Group 0, Lubrica-
tion.
BAND ADJUSTMENT
KICKDOWN BAND (FRONT)
The kickdown band adjusting screw is located on
left side (top front) of the transaxle case.
(1) Loosen locknut and back off nut approximately
five turns. Test adjusting screw for free turning in
the transaxle case.
(2) Using wrench, tighten adjusting screw to 8
N´m (72 in. lbs.).

(13) Using Miller Special Tool L-4436-A and an
inch-pound torque wrench, check the turning torque
of the differential (Fig. 299). The turning torque
should be between 5-18 inch-pounds.
NOTE: If turning torque is too high install a .05mm
(.002 inch) thicker shim. If the turning torque is too
low, install a .05mm (.002 inch) thinner shim. Repeat
until 5-18 inch-pounds of turning torque is
obtained.
CLEANING AND INSPECTION
CLEANING VALVE BODY
Prior to removing any transaxle parts, plug all
openings and clean unit, preferably by steam. Clean-
liness through entire disassembly and assembly can-
not be overemphasized. When disassembling, each
part should be washed in a suitable solvent, then
dried by compressed air.Do not wipe parts with
shop towels.All mating surfaces in the transaxles
are accurately machined; therefore, careful handling
of all parts must be exercised to avoid nicks or burrs.
NOTE: Tag all springs, as they are removed, for
reassembly identification.

CLEANING AND INSPECTION
TRANSAXLE
Clean the gears, bearings, shafts, synchronizers,
thrust washers, oil feeder, shift mechanism, gear
case, and bellhousing with solvent. Dry all parts
except the bearings with compressed air. Allow thebearings to either air dry or wipe them dry with
clean shop towels.
Inspect the gears, bearings, shafts and thrust
washers. Replace the bearings and cups if the rollers
are worn, chipped, cracked, flat spotted, or brin-
nelled, or if the bearing cage is damaged or distorted.
Replace the thrust washers if cracked, chipped, or
worn. Replace the gears if the teeth are chipped,
cracked, or worn thin. Inspect the synchronizers.
Replace the sleeve if worn or damaged in any way.
Replace the stop rings if the friction material is
burned, flaking off, or worn. Check the condition of
the synchro struts and springs. Replace these parts if
worn, cracked, or distorted.
SYNCHRONIZER
CLEAN
Do not attempt to clean the blocking rings in sol-
vent. The friction material will become contaminated.
Place synchronizer components in a suitable holder
and clean with solvent. Air dry.
INSPECT
Proper inspection of components involve:
²Teeth, for wear, scuffed, nicked, burred, or bro-
ken teeth
²Struts, for wear or distortion
²Springs, for distortion, cracks, or wear
If any of these conditions exist in these compo-
nents, replace as necessary.
ADJUSTMENTS
GEARSHIFT CROSSOVER CABLE
Before replacing the gearshift cables for a hard-
shifting complaint, disconnect both cables at the
transaxle. Then, from the driver's seat, manually
operate the gearshift lever through all gear ranges. If
the gearshift lever moves smoothly, the cable(s)
should NOT be replaced. If the gear lever binds
replace the cable that is causing the binding condi-
tion. If the problem still exists, check the crossover
cable adjustment (Fig. 210).
(1) Working over the left front fender, remove the
auxiliary vent from the selector shaft housing (Fig.
211).
(2) Locate the gearshift lock pin that has been
included in the new vehicle packet located in the
glove box.
(3) Place transaxle gearshift in the neutral posi-
tion.
(4) Insert lock pin (so long end is down) into same
threaded hole (Fig. 212). A hole in the selector shaft
will align with the lock pin, allowing the lock pin to
