STARTING AND OPERATING 295 Overdrive Operation The automatic transmission contains an electronically controlled fourth and fifth (if equipped) speed (OVERDRIVE). The transmission will automatically shift from DRIVE to OVERDRIVE if the following conditions are present: • the transmission selector is in DRIVE; • the engine coolant has reached normal operating temperature; • vehicle speed is above approximately 30 mph (48 km/h); • the TOW/HAUL switch has not been activated; • transmission temperature. has reached normal operating NOTE: If the vehicle is started in extremely cold temperatures, the transmission may not shift into OVERDRIVE 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. 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 Temperature Indicator Light" may illuminate and the transmission may downshift out of OVERDRIVE until the transmission cools down. After cooldown, the transmission will resume normal operation. The transmission will downshift from OVERDRIVE to DRIVE if the accelerator pedal is fully depressed at vehicle speeds above approximately 35 mph (56 km/h). 5

Overdrive Operation
The automatic transmission contains an electronically
controlled fourth and fifth (if equipped) speed (OVER-
DRIVE). The transmission will automatically shift from
DRIVE to OVERDRIVE if the following conditions are
present:
the transmission selector is in DRIVE;
the engine coolant has reached normal operating tem-
perature;
vehicle
speed
is
above
approximately
30
mph
(48 km/h);
the TOW/HAUL switch has not been activated;
transmission
has
reached
normal
operating
temperature.
NOTE:
If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into OVER-
DRIVE 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.
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
Temperature Indicator Light” may illuminate and the
transmission may downshift out of OVERDRIVE until
the transmission cools down. After cooldown, the trans-
mission will resume normal operation.
The transmission will downshift from OVERDRIVE to
DRIVE if the accelerator pedal is fully depressed at
vehicle speeds above approximately 35 mph (56 km/h).
