TILT STEERING COLUMN
DISASSEMBLY
(1) Remove the steering column from the vehicle, if
necessary. Refer to the removal procedure.
(2) If the column is removed for service, fabricate a
support fixture to clamp it in a vise (Fig. 1).
(3) If the steering column has not been removed
from the vehicle, place the front wheels in the
straight-ahead position. Disconnect the battery nega-
tive cable.
(4) Protect the painted areas on the steering col-
umn.
(5) Remove the steering wheel. Refer to the re-
moval procedure.
(6) Column shift: Remove the gear selector lever
retaining pin and the lever from the housing.
(7) Remove the lockplate cover. Use two small pry
bars to pry the cover off the lockplate.
WARNING: THE LOCKPLATE RETAINS A VERY
STRONG, SPRING FORCE. DO NOT ATTEMPT TO
REMOVE THE STEERING SHAFT RETAINING SNAP
RING WITHOUT USING LOCKPLATE COMPRESSOR
C-4156.
(8) Compress the lockplate with Lock Plate Com-
pressor C-4156 and release the steering shaft retain-
ing snap ring (Fig. 2).
(9) Remove the lockplate compressor tool and the
retaining snap ring. Discard the snap ring.
(10) Remove the lockplate, canceling cam, upper
bearing preload spring, and the thrust washer from
the steering column/shaft.(11) Remove the hazard warning switch knob.
Press the knob inward and remove it from the steer-
ing column by turning it counterclockwise.
(12) If the steering column is the column shift
type, remove the two retaining screws and the gear
selector indicator cover.
(13) If the steering column is the column shift
type, remove the gear selector indicator lamp bracket
retaining screw. Do not remove the lamp and bracket
at this time.
(14) Remove the tilt-release lever.
(15) Disconnect the turn signal wire harness con-
nector from the bracket located at the lower end of

(4) Apply parking brakes.
(5) Shift transmission momentarily into all gear
ranges. Then shift transmission back to Neutral.
(6) Clean top of filler tube and dipstick to keep dirt
from entering tube.
(7) Remove dipstick and check fluid level as fol-
lows:
(a) Dipstick has three fluid level indicator levels
(Fig. 1) which are: a MIN dot, an OK crosshatch
area, and a MAX fill arrow.
(b) Correct maximum level is to MAX arrow
mark. Correct acceptable level is to OK mark in
crosshatch area.
(c) Incorrect level is at or below MIN dot.
(d) If fluid is low, add only enough Mopar ATF
Plus to restore correct level. Do not overfill.
CAUTION: Do not overfill the transmission. Overfill-
ing may cause leakage out the pump vent which
can be mistaken for a pump seal leak. Overfilling
will also cause fluid aeration and foaming as the ex-
cess fluid is picked up and churned by the gear
train. This will significantly reduce fluid life.
EFFECTS OF INCORRECT FLUID LEVEL
A low fluid level allows the pump to take in air
along with the fluid. Air in the fluid will cause fluid
pressures to be low and develop slower than normal.
If the transmission is overfilled, the gears churn
the fluid into foam. This aerates the fluid causing the
same conditions that occur with a low level.
In either case, air bubbles cause fluid overheating,
oxidation and varnish buildup which interferes with
valve, clutch and servo operation. Foaming also
causes fluid expansion which can result in fluid over-
flow from the transmission vent or fill tube. Fluid
overflow can easily be mistaken for a leak if inspec-
tion is not careful.
TRANSMISSION THROTTLE VALVE CABLE
ADJUSTMENT
Throttle cable adjustment is important to proper
operation. This adjustment positions the throttle
valve which controls shift speed, quality and part
throttle downshift sensitivity.
If cable adjustment 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. Refer to the In-Ve-
hicle Service section for adjustment procedure.
GEARSHIFT CABLE/LINKAGE ADJUSTMENT
Gearshift cable/linkage adjustment is important be-
cause it positions the valve body manual valve. Incor-
rect adjustment will cause creeping in Neutral,
premature clutch wear, delayed engagement in any
gear, or a no-start in Park or Neutral position.Proper operation of the neutral start switch will
provide a quick check on adjustment. Refer to the In-
Vehicle Service section for adjustment procedure.
ROAD TEST
Before road testing, be sure the fluid level and all
cable/linkage adjustments have been checked and ad-
justed if necessary.
Observe engine performance during the road test. A
poorly tuned engine will not allow an accurate anal-
ysis of transmission operation.
Operate the transmission in all gear ranges. Check
for slippage and shift variations. Note whether the
shifts are harsh, spongy, delayed, early, or if part
throttle downshifts are sensitive.
Watch closely for slippage or engine flare which
usually indicates clutch, band or overrunning clutch
problems. If the condition is advanced, an overhaul
may be necessary to restore normal operation.
A slipping clutch or band can often be determined
by comparing which internal units are applied in the
various gear ranges. The Clutch and Band Applica-
tion chart (Fig. 3) provides a basis for analyzing road
test results.
ANALYZING THE ROAD TEST
Refer to the Clutch and Band Application chart
(Fig. 3) and note which elements are in use in the
various gear ranges.
The rear clutch is applied in all forward ranges (D,
2, 1). The overrunning clutch is applied in first gear
(D and 2 range only). The rear band is applied in 1
and R range only.
For example: If slippage occurs in first gear in D
and 2 range but not in 1 range, the overrunning

RECOMMENDED FLUID
Recommended (and preferred) fluid for 30RH/32RH
transmissions is Mopar ATF Plus, type 7176.
Dexron II is not really recommended and should
only be used when ATF Plus is not available.
FLUID LEVEL CHECK
Transmission fluid level should be checked monthly
under normal operation. If the vehicle is used for
trailer towing or similar heavy load hauling, check
fluid level and condition weekly.
Fluid level is checked with the engine running at
curb idle speed, the transmission in Neutral and the
transmission fluid at normal operating temperature.
FLUID LEVEL CHECK PROCEDURE
(1) Transmission fluid must be at normal operating
temperature for accurate fluid level check. Drive ve-
hicle if necessary to bring fluid temperature up to
normal hot operating temperature of 82ÉC (180ÉF).
(2) Position vehicle on level surface. This is ex-
tremely important for accurate fluid level check.
(3) Start and run engine at curb idle speed.
(4) Apply parking brakes.
(5) Shift transmission momentarily into all gear
ranges. Then shift transmission back to Neutral.
(6) Clean top of filler tube and dipstick to keep dirt
from entering tube.
(7) Remove dipstick and check fluid level as fol-
lows:
(a) Dipstick has three fluid level indicator levels
(Fig. 1) which are a MIN dot, an OK crosshatch
area, and a MAX fill arrow.
(b) Correct maximum level is to MAX arrow
mark. Correct acceptable level is to OK mark in
crosshatch area.
(c) Incorrect level is at or below MIN dot.
(d) If fluid is low, add only enough Mopar ATF
Plus restore correct level. Do not overfill.CAUTION: Do not overfill the transmission. Overfill-
ing may cause leakage out the pump vent which
can be mistaken for a pump seal leak. Overfilling
will also cause fluid aeration and foaming as the ex-
cess fluid is picked up and churned by the gear
train. This will reduce fluid life significantly.
FLUID AND FILTER REPLACEMENT
NORMAL CHANGE INTERVAL
The fluid and filter should be changed (and the
bands adjusted) at recommended maintenance inter-
vals, or whenever the transmission has been disas-
sembled for any reason.
Refer to the Driveline section in Group O, Lubrica-
tion and Maintenance for recommended change inter-
vals. Refer to the fluid/filter replacement and band
adjustment procedures in this section.
SEVERE USAGE CHANGE INTERVAL
Under severe usage, the fluid and filter should be
changed and the bands adjusted at 12,000 mile (19
000 Km) intervals.
Severe usage is defined as:
(a) More than half of vehicle operation occurs in
heavy city traffic during hot weather (above 90É F).
(b) Vehicle is used for taxi, police, limousine, or
similar commercial operation.
