Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled 5th speed (Overdrive). The trans-
mission will automatically shift from 4th gear to Over-
drive if the following conditions are present:
•
the transmission selector is in D (Drive);
•
the engine coolant has reached normal operating tem-
perature;
•
vehicle speed is above approximately 30 mph (48
km/h);
•
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.
During cold temperature operation, you may notice
delayed upshifts depending on engine and transmission
temperature. This feature improves the warm up time of
the engine and transmission.
During cold temperature operation, the transmission
may not downshift from 2nd (2) gear to 1st (1) gear after
the initial 1st (1) to 2nd (2) gear upshift.
Transmission Limp Home Mode
Transmission function is monitored for abnormal condi-
tions. If a condition is detected that could result in
transmission damage, the transmission limp home mode
will be engaged. In this mode, the transmission will
remain in the current gear until the vehicle is brought to
a stop.
To reset the transmission, use the following procedure:
