Driver Controls and Instruments
Transmission Oil Temperature Gauge
With an Allison automatic transmission, the transmission
oil temperature gauge reading should not exceed 250°F
(121°C) during normal operation. A warning light will
activate to alert the driver.
CAUTION
A sudden increase in oil temperature that is not
caused by a load increase may indicate mechanical
failure. Bring the vehicle to a safe stop and investi-
gate the cause to prevent further damage. Do not
operate the engine until the cause has been deter-
mined and corrected.

A temperature control lever is used to select the desired

• The Floor/Panel position directs air through the
windshield, floor, side panel, and center panel
(unheated) vents.
• The Defrost position directs air through the wind-
shield and side panel vents. The center panel
vents, if left open, will provide unheated air. Air
flow from the side panel vents, when directed to-
ward the door windows, will help avoid window
fogging.
• The Panel position directs unheated air through
the center panel vents only.
