[GF10410(ALL)05/96]
Increasing the engine speed above idle without
vehicle movement (such as holding the brake) in
a forward or reverse gear causes transmission
stall.
*
[GF10450(ALL)05/96]
NOTE: Continued operation in the stall
condition can result in transmission
overheat, malfunction or fluid
expulsion.

When to use Drive
[GF13250(ALL)01/96]
You will note there is not a drive position on
your gearshift indicator. However, you will find
a transmission control switch labeled
OVERDRIVE OFF located on the end of the
gearshift lever. Press this switch and the
indicator light (OFF) illuminates on the gearshift
lever. With overdrive cancelled and the
OVERDRIVE OFF illuminated, the transmission
will operate in gears one through three. This is
useful if you experience frequent
downshift/upshift conditions, when operating
with a heavy load or in hilly terrain, or if
additional engine braking is useful. However,
shift back toj(Overdrive) whenever practical
for optimum powertrain cooling and fuel
economy. This can be accomplished by pushing
the transmission control switch again, to cancel
the OVERDRIVE OFF control and light.
[GF13300(ALL)06/96]

When to use 2 (Second)
*
[GF13450(ALL)05/96]
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.
*
[GF13475(ALL)05/96]
When to use 1 (Low)
*
[GF14000(ALL)05/96]
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.
*
[GF14500(ALL)05/96]
Forced Downshifts
[GF14550(ALL)03/96]
To gain acceleration inj(Overdrive) or Drive
(jposition with Overdrive cancelled) when

[GF14650(ALL)05/96]
When to usej(Overdrive)
*
[GF14700(ALL)05/96]
This is the normal driving position. As the
vehicle picks up speed, automatic upshifts to
second, third, fourth and fifth gears will occur
whenj(Overdrive) is chosen on the selector
and the transmission control switch has not been
pressed. The transmission will shift into the
correct gear when the right speed is achieved,
for the accelerator pedal position you have
chosen.

178 [GF16025(ALL)01/96]How the Electronic 4-Wheel Drive (E-4WD)
System Works
[GF16036(ALL)01/96]
Under normal driving conditions, when the road
is firm, dry and level, the engine power is
distributed one-third to the front axle and
two-thirds to the rear axle. However, if a wheel
begins to slip, the microprocessor will sense this
condition and signal the system to transmit more
power to the axle with more traction. (You may
feel a momentary surge of power.)
[GF16046(ALL)01/96]
NOTE: The microprocessor is disabled when
the brakes are applied or when the
transmission selector is in the P (Park)
or N (Neutral) positions.
