“2” Second
Use this position for driving slowly in heavy city traffic or
on mountain roads where more precise speed control is
desirable. Use it also when climbing long grades, and for
engine braking when descending moderately steep grades.
NOTE: Do not exceed maximum engine speed.
“1” First
Use this position for driving up very steep hills and for
engine braking at low speeds (20 mph [32 km/h] or less)
when going downhill.
NOTE: Do not exceed maximum engine speed.
Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically 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 tem-
perature;
•
vehicle speed is above approximately 30 mph (48
km/h);
•
the “TOW HAUL O/D OFF” switch has not been
activated;
•
transmission has reached normal operating tempera-
ture.
NOTE: If the vehicle is started in extremely cold tem-
peratures, 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.
