Gauge
Your Transmission Temperature
Gauge indicates the temperature of
the oil in your transmission. Watch
this gauge to know when your
transmission is overheating. If it is,
have it checked by an authorized
service representative.
Maximum transmission
temperature
may vary, depending upon the
transmission and type of lubricant.
Check your transmission’s owner’s
manual.
Drive Axle Temperature
Gauge (Forward and Rear)
These gauges indicate the temperature
of the lubricant in your vehicle’s axle(s).
These temperatures will vary with
the kind of load you are carrying and
the driving conditions you encounter.
Maximum axle temperature may vary,
depending upon the axle and type
of lubricant. Very high temperatures
signal a need to have your axle(s)
lubrication checked.
Depending on the vehicle
conguration, there may be a
drive axle temperature gauge for
more than just the forward and rear
driver.
The icon will have an X over
the representative axle to indicate
which axle the temperature is being
displayed in the gauge.
CAUTION
Driving with very hot temperatures in
your rear drive axles can cause se
-
rious damage to axle bearings and
seals. Have your axle lubrication
checked if you notice a sign of over
-
heating.
