Transmission and Rear Axle Maintenance
Transmission
General
Transmissions should not be operated
consistently at temperatures above 250
F
(120
C).
If the temperature reaches 285
F (140 C),
stop the vehicle to let the temperature go
down (see the vehicle Operator’s Manual
for information on the optional transmission
temperature gauge).
Operating temperatures above 250
F
(120
C) increase the lubricant’s rate of
oxidation and shorten its effective life.
If the transmission oil temperatures are
consistently high, change oil more often
or install an oil cooler. With lengthy or
continuous driving at altitudes of more than
6,000 ft (2,000 m) above sea level, more
frequent oil changes will be necessary.
Note: Always dispose of oil according
to Federal or local regulations. Used
oil disposed of in nature or waterways
contaminates our drinking water and kills
wildlife. Take all used oil to a recycling or
waste collection center.
