If the Transmission Control Indicator Light is
flashing on and off steadily, a transmission
system malfunction was detected. The
transmission will operate in a failure
management mode and may have harsh
engagements, firm shift feel, or abnormal shift
schedule. If this condition persists, damage to
the transmission could occur. Contact your
dealer as soon as possible.

When to use 2 (Second)
*
[GF08300(FM)01/96]
Use 2 (Second) to start-up on slippery roads or
to provide additional engine braking on
downgrades. This position provides 2 (Second)
gear operation only.
*
[GF08325(FM)05/96]
When to use 1 (Low)
*
[GF08350(FM)01/96]
Use 1 (Low) to provide maximum engine
braking on steep downgrades. Upshifts from 1
(Low) can be made by manually shifting to 2
(Second) orj(Overdrive). Selection of 1 (Low)
gear provides only low gear operation from
start-up. Selection of 1 (Low) while at higher
speeds provides a shift to second gear, and a
shift to first gear will occur after the vehicle
decelerates to the proper speed.

P (Park)
*
[GF08400(FM)05/96]

turning. To securely latch the gearshift in the P
(Park) position, pull it toward you, push it
completely counterclockwise against the stop,
and then push it toward the instrument panel.
*
[GF08425(FM)05/96]
The gearshift is securely latched in P (Park) if
you cannot rotate it in a clockwise direction
without lifting it toward you.

[GF08450(FM)05/96]
RWARNING
Always set the parking brake fully and
make sure the gearshift is latched in P
(Park). Turn off the ignition whenever you
leave your vehicle.
[GF08475(F )05/96]
When the transfer case is in the N (Neutral)
position, the engine and transmission are
disconnected from the rest of the driveline.
Therefore, the vehicle is free to roll even if the
automatic transmission is in P (Park) or the
manual transmission is in gear.

[GF12300(F )01/96]
Make sure the gearshift lever is in the N
(Neutral) position and your right foot is holding
down the brake pedal. Then press the clutch
pedal to the floor with your left foot. Manual
transmission vehicles have a starter interlock
switch. The starter will not crank until the clutch
pedal is fully depressed. Start the engine and
allow it to idle for a few seconds. Move the
gearshift into 1 (First) or R (Reverse).
*
[GF12400(F )01/96]
To move the vehicle, release the clutch slowly
and at the same time press down slowly on the
accelerator so that the vehicle accelerates.
*
[GF12500(F )01/96]
Do not drive with your foot resting on the
clutch pedal and do not use the clutch to hold
your vehicle at a standstill while waiting on a
hill. These actions will seriously reduce clutch
life.

3. Put the gearshift in Neutral and wait at least
3 seconds before shifting into R (Reverse) to
prevent a grinding noise. Do not release the
clutch.

[GF13500(F )01/96]
4. Push the gearshift all the way to the right
and pull it back into Reverse.
*
[GF13600(F )01/96]
With the 5-speed transmission you can engage R
(Reverse) only by moving the gearshift from the
left of 3 (Third) and 4 (Fourth) gears before you
shift into R (Reverse). This is a special lockout
feature that protects you from accidentally
shifting into R when you downshift from 5
(Fifth) gear.
*
[GF13700(F )01/96]
5. Once R (Reverse) is engaged, slowly release
the clutch pedal from the floor.
*
[GF13800(F )01/96]
If R (Reverse) is not engaged, continue to push
the clutch pedal in while you put the gearshift
back into Neutral. Then, release the clutch pedal
for a moment and repeat steps 2 through 5.

When you slow down or climb a steep hill,
always downshift before the engine starts to lose
power. Downshifting reduces the chance of
stalling and gives your vehicle better acceleration
to increase speed again.
*
[GF14800(F )01/96]
When you drive down steep hills, downshifting
helps you keep a safe speed and helps prevent
unnecessary wear on the brakes.

When you come to a stop, do not downshift
through each gear. Disengage the clutch and use
the brake as necessary. Downshifting through
the gears decreases your vehicle's fuel economy.
*

Continued use of a damaged or worn
clutch, prolonged clutch slippage or
downshifting at excessive speeds can
result in a failure of the engine,

Four-Wheel Drive (4WD)
System (If equipped)
*
[GF15500(F )01/96]
When you select the 4WD mode, your light
truck uses all four wheels to power itself. This
increases traction, enabling you to drive your
4x4 over terrain and road conditions two-wheel
drive vehicles cannot.
*
[GF15600(F )01/96]
Power is supplied to all four wheels through a
transfer case that allows you to select four-wheel
drive when necessary. Methods for engaging and
disengaging 4WD and low range will depend on
which system your vehicle has.
