NOTE:
To select the proper gear position for maximum

•
the engine coolant has reached normal operating tem-
perature;
•
vehicle speed is above approximately 30 mph (48

•
the TOW/HAUL switch has not been activated;
•
transmission has reached normal operating tempera-
ture.
NOTE:
If the vehicle is started in extremely cold tem-

and will automatically select the most desirable gear for
operation at this temperature. Normal operation will
resume when the transmission fluid temperature has
risen to a suitable level. Refer also to the Note under
torque converter clutch, later in this section.
During cold temperature operation you may notice de-

temperature. This feature improves the warmup time of
the engine and transmission.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough, the “TRANSMISSION
