should occur, the TCM (Transmission Control
Module) will command converter operation
(disconnect lockup) and inhibit downshifts for a
period of time or until normal wheel speed has
been restored.
IMPORTANT NOTE
Brake pedal must be applied when selecting
«D» (Drive) otherwise the transmission will
stay in «N» (Neutral).
NOTE
The transmission should normally be allowed
to shift by itself, but manual shifting can be
done as described below.
1 (First range)
Select this range when pulling through mud and
snow, when speed control is needed for driving
up or down steep grades or when maneuvering
in tight spaces. This range also provides
maximum driving torque and engine braking
power or retarder braking effect. In the lower
ranges (1, 2, 3 and 4), the transmission will not
upshift above the highest gear selected unless
engine overspeed is detected.
2 (Second range)
Select this range when operating in heavy and
congested traffic. The transmission will start in
first and automatically upshift to second. When
slowing, the transmission will automatically
downshift to first range. Low ranges provide
progressively greater engine and retarder
braking power (the lower the range, the greater
the engine and retarder braking effect).
3, 4 (Third and fourth ranges)
Select these ranges when driving on moderate
grades or when load and traffic conditions limit
speed.
WARNING
Service brake should not be used to control
the speed of vehicle on long, steep descents.
Instead, lower transmission ranges should be
used (in conjunction with output retarder.
Refer to "Engine Brake" and "Transmission
Retarder" headings in Section 5
Other
Features
for details regarding both systems.
This procedure keeps service brake cool and
ready for emergency stopping.
CAUTION
When descending in lower ranges, care must
be taken that engine speed does not exceed
2,450 rpm.
