ROCKING OUT
WARNING: To help avoid injury or property damage caused by sudden
movement of the vehicle, do not make shifts from N (Neutral) to
D (Drive) or R (Reverse) when the throttle is open. The vehicle will
lurch forward or rearward and the transmission can be damaged. Avoid
this condition by making shifts from
N (Neutral) to a forward range or
R (Reverse) only when the throttle is closed and the service brakes are
applied.
CAUTION: DO NOT make N (Neutral) to D (Drive) or directional
shift changes when the engine rpm is above idle. Also, if the wheels are
stuck and not turning, do not apply full power for more than 10 seconds
in either
D (Drive) or R (Reverse). Full power for more than 10 seconds
under these conditions will cause the transmission to overheat. If the
transmission overheats, shift to
N (Neutral) and operate the engine at
1200–1500 rpm until it cools (2–3 minutes).
If the vehicle is stuck in deep sand, snow, or mud, it may be possible to rock it
out using the following procedure:
1. Shift to D (Drive) and apply steady, light throttle ( never full throttle ).
2. When the vehicle has rocked forward as far as it will go, apply and hold
the vehicle service brakes.
3. When engine has returned to idle, select R (Reverse).
4. Release the brakes and apply a steady, light throttle allowing the vehicle to
rock in R (Reverse) as far as it will go.
5. Again, apply and hold the service brakes and allow the engine to return to
idle.
This procedure may be repeated in D (Drive) and R (Reverse) if each directional
shift continues to move the vehicle a greater distance. Never make
N (Neutral)-to- D (Drive) or directional shift changes when the engine rpm is
above idle.
HIGH FLUID TEMPERATURE
