Summary Chart" may vary somewhat due to pro-
duction tolerances and rear axle ratios. This is not
too important; however, the quality of the shifts
is
very important.
All shifts should be smooth,
re-
sponsive, and with no noticeable engine runaway.
Starting the Engine
The engine will start with the selector lever in
either the P (park) or
N
(neutral) positions.
(1) As a safety precaution when starting in the N
(neutral) position, apply the parking or foot brake.
(2) Depress the accelerator pedal one-third of travel
to insure proper choke operation.
(3) Turn the ignition key all the way to the right to
START position. When the engine starts, release the
key and it will return to the ON position.
Push Starting
If the engine fails to start in the normal manner, it
may be started by pushing.
Towing the vehicle to start
is not recommended due to the sudden surge
of power
when the engine starts.
Turn the ignition on, then move the selector lever
to the low position and depress the accelerator pedal
slightly. After the vehicle has been pushed to a speed
of 15 to 25 mph, the transmission will drive the en-
gine.
Mountain Driving
When driving in the mountains with either heavy
loads or when pulling trailers, the
2
(second) or 1 (low)
position should be selected on upgrades which re-
quire heavy throttle for
3 4 2
mile or more. Lower ra-
tios reduce possibility of overheating the transmis-
sion and converter under these conditions. 1 (low) po-
sition is for severe operation or to obtain better con-
trol.
