FLUID AND FILTER
DIAGNOSIS AND TESTING
CAUSES OF BURNT FLUID
Burnt, discolored fluid is a result of overheating which has two primary causes.
1. A result of restricted fluid flow through the main and/or auxiliary cooler. This condition is usually the result of a
faulty or improperly installed drainback valve, a damaged oil cooler, or severe restrictions in the coolers and lines
caused by debris or kinked lines.
2. Heavy duty operation with a vehicle not properly equipped for this type of operation. Trailer towing or similar high
load operation will overheat the transmission fluid if the vehicle is improperly equipped. Such vehicles should
have an auxiliary transmission fluid cooler, a heavy duty cooling system,and the engine/axle ratio combination
needed to handle heavy loads.
EFFECTS OF INCORRECT FLUID LEVEL
Alowfluidlevelallowsthepumptotakeinairalongwiththefluid.Airinthe fluid will cause fluid pressures to be
low and develop slower than normal. If the transmission is overfilled, thegears churn the fluid into foam. This aer-
ates the fluid and causing the same conditions occurring with a low level. In either case, air bubbles cause fluid
overheating, oxidation, and varnish buildup which interferes with valveand clutch operation. Foaming also causes
fluid expansion which can result in fluid overflow from the transmission vent or fill tube. Fluid overflow can easily be
mistaken for a leak if inspection is not careful.
FLUID CONTAMINATION
Transmission fluid contamination is generally a result of:
adding incorrect fluid
failure to clean dipstick and fill tube when checking level
engine coolant entering the fluid
internal failure that generates debris
overheat that generates sludge (fluid breakdown)
failure to replace contaminated converter after repair
The use of non-recommended fluids can result in transmission failure. Theusual results are erratic shifts, slippage,
abnormal wear and eventual failure due to fluid breakdown and sludge formation. Avoid this condition by using rec-
ommended fluids only.
The dipstick cap and fill tube should be wiped clean before checking fluid level. Dirt, grease and other foreign mate-
rial on the cap and tube could fall into the tube if not removed beforehand. Take the time to wipe the cap and tube
clean before withdrawing the dipstick.
Engine coolant in the transmission fluid is generally caused by a cooler malfunction. The only remedy is to replace
the radiator as the cooler in the radiator is not a serviceable part. If coolant has circulated through the transmission,
an overhaul is necessary.
The torque converter should also be replaced whenever a failure generatessludge and debris. This is necessary
because normal converter flushing procedures will not remove all contaminants.
STANDARD PROCEDURE
FLUID LEVEL CHECK
The transmission sump has a dipstick to check oil similar to most automatictransmissions. It is located on the left
side of the engine. Be sure to wipe all dirt from dipstick handle before removing.
The torque converter fills in both the PARK and NEUTRAL positions. Place the selector lever in PARK to be sure
that the fluid level check is accurate.The engine should be running at idle speed for at least one minute, with
the vehicle on level ground.At normal operating temperature (approximately 82° C or 180° F), the fluidlevel is
correct if it is in the HOT region (cross-hatched area) on the oil level indicator. The fluid level should be in COLD
region at 21° C (70° F) fluid temperature. Adjust fluid level as necessary.Use only Mopar
ATF+4, Automatic Trans-
mission Fluid.

2. Check the wheel radial runout.
3. Check the wheel lateral runout.
STEEL WHEELS: Radial runout 0.031 in., Lateral
runout 0.031 in. (maximum)
ALUMINUM WHEELS: Radial runout 0.02 in.,
Lateral runout 0.025 in. (maximum)
4. If point of greatest wheel lateral runout is near orig-
inal chalk mark, remount tire 180 degrees.
Recheck runout.
STANDARD PROCEDURE
MATCH MOUNTING
Wheels and tires are match mounted at the factory. This means that the high spot of the tire is matched to the low
spot on the wheel rim. Each are marked with a bright colored temporary labelon the outboard surface for alignment.
The wheel is also marked permanently on the inside of the rim in the tire well. This permanent mark may be a paint
dot or line, a permanent label or a stamped impression such as an X. An optional location mark is a small spherical
indentation on the vertical face of the outboard flange on some non styled base steel wheels. The tire must be
removed to locate the permanent mark on the inside of the wheel.
Before dismounting a tire from its wheel, a reference mark should be placedon the tire at the valve stem location.
This reference will ensure that it is remounted in the original position onthe wheel.
1. Remove the tire and wheel assembly from the
vehicle and mount on a service dynamic balance
machine.
2. Measure the total runout on the center of the tire
tread rib (3) with a dial indicator. Record the indi-
cator reading. Mark the tire to indicate the high
spot (2). Place a mark on the tire at the valve stem
(4) location (1).

3. Break down the tire and remount it 180 degrees
on the rim (1)(2).
4. Measure the total indicator runout again. Mark the
tire to indicate the high spot.
5. If runout is still excessive, the following procedures
must be done.
If the high spot is within 101.6 mm (4.0 in.) of the
first spot and is still excessive, replace the tire.
If the high spot is within 101.6 mm (4.0 in.) of the
first spot on the wheel, the wheel may be out of
specifications. Refer to Wheel and Tire Runout.
IfthehighspotisNOTwithin101.6mm(4.0in.)
of either high spot, draw an arrow on the tread
from second high spot (1) to first (2). Break down
the tire and remount it 90 degrees on rim in that
direction. This procedure will normally reduce the
runout to an acceptable amount, if not replace
the rim.
TIRE AND WHEEL BALANCE
It is recommended that a two plane service dynamic balancer be used when a tire and wheel assembly require
balancing. Refer to balancer operation instructions for proper cone mounting procedures. Typically use front cone
mounting method for steel wheels. For aluminum wheel use back cone mounting method without cone spring.
NOTE: Static should be used only when a two plane balancer is not available.
NOTE: Cast aluminum and forged aluminum wheels require coated balance weights and special alignment
equipment.
Wheel balancing can be accomplished with either on or off vehicle equipment. When using on-vehicle balancing
equipment, remove the opposite wheel/tire. Off-vehicle balancing is recommended.

B1001–A/C SWITCH REQUEST INPUT CIRCUIT LOW (SINGLE-ZONE)
For a complete wiring diagramRefer to Section 8W.
Theory of Operation
The A/C mode switch input changes when the switch is pushed down. A stored DTC B1001 indicates that the A/C
mode switch was stuck in a pushed position for more than two minutes, but hassince returned to its normal state.
An active DTC B1001 indicates that the A/C mode switch is stuck in a pushed position.AnactiveDTCB1001will
also prevent proper A/C mode switch and status indicator function as evidenced by not being able to turn the A/C
status indicator either on if off or off if on.
When Monitored:
With the ignition on.
Set Condition:
If the A/C mode switch stays in a pushed position for more than two minutes. This DTC has a maturing time
