TRANSMISSION FILL
To avoid overfilling transmission after a fluid change or overhaul, perform the following procedure:
1. Remove dipstick and insert clean funnel in transmission fill tube.
2. Add following initial quantity of Mopar
ATF+4totransmission:
a. If only fluid and filter were changed, add3 pints (1-1/2 quarts)of ATF +4 to transmission.
b. If transmission was completely overhauled, torque converter was replaced or drained, and cooler was
flushed, add12 pints (6 quarts)of ATF +4 to transmission.
3. Apply parking brakes.
4. Start and run engine at normal curb idle speed.
5. Apply service brakes, shift transmission through all gear ranges then back to NEUTRAL, set parking brake, and
leave engine running at curb idle speed.
6. Remove funnel, insert dipstick andcheck fluid level. If level is low,add fluid to bring level to MIN mark on
dipstick.Check to see if the oil level is equal on both sides of the dipstick. If one side is noticably higher than
the other, the dipstick has picked up some oil from the dipstick tube. Allowthe oil to drain down the dipstick tube
and re-check.
7. Drive vehicle until transmission fluid is at normal operating temperature.
8. With the engine running at curb idle speed, the gear selector in NEUTRAL,and the parking brake applied, check
the transmission fluid level.
CAUTION: Do not overfill transmission, fluid foaming and shifting problems can result.
9. Add fluid to bring level up to MAX arrow mark.
When fluid level is correct, shut engine off, release park brake, remove funnel, and install dipstick in fill tube.

DISASSEMBLY
CAUTION: Do not clamp any valve body component in a vise. This practice can damage the component
resulting in unsatisfactory operation after assembly and installation.Do not use pliers to remove any of the
valves, plugs or springs and do not force any of the components out or into place. The valves and valve
body housings will be damaged if force is used. Tag or mark the valve body springs for reference as they
are removed. Do not allow them to become intermixed.
sharpness of these edges is vitally important. The edges prevent foreign matter from lodging between the valves
and plugs and the bore.
Inspect all the valve and plug bores in the valve body. Use a penlight to viewthe bore interiors. Replace the valve
body if any bores are distorted or scored. Inspect all of the valve body springs. The springs must be free of dis-
tortion, warpage or broken coils.
Check the two separator plates for distortion or damage of any kind. Inspect the upper housing, lower housing, 3-4
accumulator housing, and transfer plate carefully. Be sure all fluid passages are clean and clear. Check condition of
the upper housing and transfer plate check balls as well. The check balls and ball seats must not be worn or dam-
aged.
Trial fit each valve and plug in its bore to check freedom of operation. Whenclean and dry, the valves and plugs
shoulddropfreelyintothebores.
Valve body bores do not change dimensionally with use. If the valve body functioned correctly when new, it will
continue to operate properly after cleaning and inspection. It should notbe necessary to replace a valve body
assembly unless it is damaged in handling.
The only serviceable valve body components are listed below. The remaining valve body components are serviced
only as part of a complete valve body assembly. Serviceable parts are:
dual solenoid and harness assembly
solenoid gasket
solenoid case connector O-rings and shoulder bolt
switch valve and spring
pressure adjusting screw and bracket assembly
throttle lever
manual lever and shaft seal
throttle lever shaft seal, washer, and E-clip
fluid filter and screws
detent ball and spring
valve body screws
governor pressure solenoid
governor pressure sensor and retaining clip
park lock rod and E-clip
ASSEMBLY
CAUTION: Do not force valves or plugs into place during reassembly. If the valve body bores, valves and
plugs are free of distortion or burrs, the valve body components should allslide into place easily. In addi-
tion, do not overtighten the transfer plate and valve body screws during reassembly. Overtightening can
distort the housings resulting in valve sticking, cross leakage and unsatisfactory operation. Tighten valve
body screws to recommended torque only.
INSTALLATION
1. Check condition of O-ring seals (1) on valve body
harness connector (2). Replace seals on connector
body if cut or worn.
2. Check condition of manual lever shaft seal (2) in
transmission case. Replace seal if lip is cut or
worn. Install new seal with 15/16 deep well socket
(1).
3. Check condition of seals on accumulator piston. Install new piston seals, if necessary.
4. Place valve body manual lever in low (1 position) so ball on park lock rod will be easier to install in sprag.
5. Lubricate shaft of manual lever with petroleum jelly. This will ease inserting shaft through seal in case.
6. Lubricate seal rings on valve body harness connector with petroleum jelly.
7. Position valve body in case and work end of park lock rod into and through pawl sprag. Turn propeller shaft to
align sprag and park lock teeth if necessary. The rod will click as it enterspawl. Move rod to check engagement.
CAUTION: It is possible for the park rod to displace into a cavity just abovethe pawl sprag during instal-
lation. Make sure the rod is actually engaged in the pawl and has not displaced into this cavity.
8. Install accumulator spring and piston into case. Then swing valve body overpistonandouterspringtoholditin
place.
9. Align accumulator piston and outer spring, manual lever shaft and electrical connector in case.
10. Then seat valve body in case and install one or two bolts to hold valve bodyinplace.
11. Tighten valve body bolts alternately and evenly to 11 Nꞏm (100 in. lbs.)torque.
12. Install new fluid filter on valve body. Tighten filter screws to 4 Nꞏm (35 in. lbs.) torque.
13. Install throttle and gearshift levers on valve body manual lever shaft.

ACCUMULATOR-A/C
DESCRIPTION
The A/C accumulator (5) is mounted in the engine
compartment between the evaporator outlet tube (2)
and the A/C suction line (6). An integral mounting
bracket (4) is used to secure the accumulator to the
dash panel (3). The A/C low side service port (1) is
mountedtothetopoftheA/Caccumulator.
CAUTION: Use only O-ring seals specified for the
vehicle. Failure to use the correct O-ring seal will
cause the refrigerant system connections to leak.
The A/C accumulator has no serviceable parts except
for the rubber O-ring seals, low side service port
valve, cap and secondary retaining clips. The O-ring
seals used on the connections are made from a spe-
cial type of rubber not affected by R-134a refrigerant.
The O-ring seals must be replaced whenever the A/C
accumulator is removed and installed.
The A/C accumulator cannot be repaired and, if faulty
or damaged, it must be replaced.
OPERATION
Refrigerant enters the A/C accumulator (1) mostly as a
low pressure vapor through the inlet tube (2). Any liq-
uid, oil-laden refrigerant falls to the bottom of the can-
ister, which acts as a separator. A desiccant bag (3) is
mounted inside the accumulator canister to absorb
any moisture which may have entered and become
trapped within the refrigerant system. A filter (4) is also
mounted inside the canister to trap any foreign mate-
rial that may have entered the refrigerant system dur-
ing assembly. The low pressure vapor exits the A/C
accumulator through the outlet tube (5). On this
model, the low side service port (6) is located at the
top of the A/C accumulator.
The A/C accumulator cannot be repaired. If the A/C
accumulator is faulty or damaged, or if the A/C com-
pressor has failed, it must be replaced.
