Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled fourth and fifth (if equipped) speed
(Overdrive). The transmission will automatically shift
from Drive to Overdrive if the following conditions are
present:
²the transmission selector is in Drive;
²the engine coolant has reached normal operating tem-
perature;
²vehicle speed is above approximately 30 mph (48
km/h);
²the ªTOW/HAULº switch has not been activated;
²transmission has reached normal operating tempera-
ture.
NOTE:If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdriveand will automatically select the most desirable gear for
operation at this temperature. Normal operation will
resume when the transmission fluid temperature has
risen to a suitable level. Refer also to the Note under
torque converter clutch, later in this section.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough the TRANS TEMP light
may illuminate and the transmission may downshift out
of Overdrive until the transmission cools down. After
cooldown, the transmission will resume normal opera-
tion.
The transmission will downshift from Overdrive to Drive
if the accelerator pedal is fully depressed at vehicle
speeds above approximately 35 mph (56 km/h).

When To Use ªTOW/HAULº Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the ªTOW/HAULº button. This will improve
performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in ªTOW/HAULº mode, 5th gear (ifequipped) is disabled and 2-3 and 3-4 shift patterns are
modified. Shifts into Overdrive (4th gear) are allowed
during steady cruise (for improved fuel economy) and
automatic closed-throttle downshifts to 3rd gear (for
improved braking) will occur during steady braking.
The ªTOW/HAULº light will illuminate in the instru-
ment cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the ªTOW/HAULº mode is desired,
the button must be pressed each time the engine is
started.
Torque Converter Clutch
A feature, designed to improve fuel economy, has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation in
212 STARTING AND OPERATING

high gear. When the vehicle speed drops or during
acceleration when the transmission downshifts to second
gear, the clutch automatically disengages.
NOTE:The torque converter clutch will not engage
until the transmission fluid and engine coolant are warm
[usually after 1-3 miles (1.6 - 4.8 km) of driving]. Because
the engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmission
is not shifting into Overdrive when cold. This is normal.
Pressing the ªTOW/HAULº button, when the transmis-
sion is sufficiently warm, will demonstrate that the
transmission is able to shift into and out of overdrive.
NOTE:If the vehicle has not been driven in several
days, the first few seconds of operation after shifting the
transmission into gear may seem sluggish. This is due tothe fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque converter
will refill within five seconds of shifting from Park into
any other gear position.
Manual Transmission Ð 5-Speed
NOTE:The parking brake should be engaged before
leaving the vehicle, especially on an incline.
Truck models with manual transmission are equipped
with a clutch interlocking ignition system. The clutch
pedal must be fully depressed to start the vehicle.
Fully depress the clutch pedal before shifting gears. As
you release the clutch pedal, lightly depress the accelera-
tor pedal.
STARTING AND OPERATING 213

NOTE:If the 2500/3500 bottle jack will not lower by
turning the dial (thumb wheel) by hand, it may be
necessary to use the jack drive tube in order to lower the
jack.
4. By rotating the wheel wrench clockwise, raise the
vehicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
5. Remove the wheel nuts and pull the wheel off. Install
the spare wheel and wheel nuts with the cone shaped endof the nuts toward the wheel on 2500/3500 single rear
wheel (SRW) models. On 3500 dual rear wheel models
(DRW) the lug nuts are a two piece assembly with a flat
face. Lightly tighten the nuts. To avoid risk of forcing the
vehicle off the jack, do not fully tighten the nuts until the
vehicle has been lowered.
6. Using the wheel wrench, finish tightening the nuts
using a crisscross pattern. Correct nut tightness is 135 ft.
lbs. (183 N´m) torque for 2500/3500 single rear wheel
(SRW) models and 145 ft. lbs. (197 N´m) for 3500 dual rear
wheel models. If in doubt about the correct tightness,
have them checked with a torque wrench by your dealer
or at a service station.
WHAT TO DO IN EMERGENCIES 307

1. Tighten the wheel nuts in the numbered sequence to a
snug fit.
2. Retighten the wheel nuts in the same sequence to the
torques listed in the table. Go through the sequence a
second time to verify that specific torque has been
achieved. Retighten to specifications at 100 miles (160
km) and after 500 miles (800 km).
It is recommended that wheel stud nuts be kept torqued
to specifications at all times. Torque wheel stud nuts to
specifications at each lubrication interval.
Wheel Nuts
All wheel nuts should be tightened occasionally to elimi-
nate the possibility of wheel studs being sheared or the
bolt holes in the wheels becoming elongated. This is
especially important during the first few hundred miles
of operation to allow the wheel nuts to become properly
set. All nuts should first be firmly seated against thewheel. The nuts should then be tightened to recom-
mended torque. Tighten the nuts to final torque in
increments. Progress around the bolt circle, tightening
the nut opposite to the nut just previously tightened until
final torque is achieved. Recommended torques are
shown in the following chart.

To Stow The Flat Or Spare
Turn the wheel so that the valve stem is down. Slide the
wheel retainer through the center of the wheel and
position it properly across the wheel opening.
For convenience in checking the spare tire inflation, stow
with the valve stem toward the rear of the vehicle.

CAUTION!
Be aware that if the fluid temperature is below 50ÉF
(10ÉC) it may not register on the dipstick. Do not add
fluid until the temperature is elevated enough to
produce an accurate reading.
7. Check for leaks. Release parking brake.
To prevent dirt and water from entering the transmission
after checking or replenishing fluid, make certain that the
dipstick cap is properly reseated. It is normal for the
dipstick cap to spring back slightly from its fully seated
position, as long as its seal remains engaged in the
dipstick tube.
Selection Of Lubricant
Refer to Recommended Fluids, Lubricants and Genuine
Parts for correct fluid type. It is important that the
transmission fluid be maintained at the prescribed level
using the recommended fluid.
CAUTION!
Using a transmission fluid other than the manufac-
turers recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturers recommended fluid will result in
more frequent fluid and filter changes. Refer to
Recommended Fluids, Lubricants and Genuine Parts
for correct fluid type.
