84 STARTING AND OPERATING
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission
automatically upshifts through all forward gears.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong head
winds, or while towing a heavy trailer), use the AutoStick
shift control to select a lower gear
Ú
these conditions, using a lower gear will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup.
If the transmission temperature exceeds normal operating
limits, the transmission controller may modify the
transmission shift schedule, reduce engine torque, and/or
expand the range of torque converter clutch engagement.
This is done to prevent transmission damage due to
overheating.
If the transmission becomes extremely hot, the
Transmission Temperature Warning Light may illuminate,
and the transmission may operate differently until the
transmission cools down.
During cold temperatures, transmission operation may be
modified depending on engine and transmission
temperature as well as vehicle speed. This feature
improves warm-up time of the engine and transmission to
achieve maximum efficiency. Engagement of the torque
converter clutch, and shifts into EIGHTH or NINTH gear,
are inhibited until the transmission fluid is warm
page 85. Normal operation will resume once the
Ú
transmission temperature has risen to a suitable level.
SPORT — If Equipped
This mode alters the transmission's automatic shift
schedule for sportier driving. Upshift speeds are increased
to make full use of available engine power.
SPORT mode is activated using the rotary switch on the
center console
Transmission Limp Home Mode
Transmission function is monitored electronically for
page 84. Under abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
mode is activated. In this mode, the transmission may
operate only in a fixed gear, or may remain in NEUTRAL.
The Malfunction Indicator Light (MIL) may be illuminated.
Limp Home mode may allow the vehicle to be driven to an
authorized dealer for service without damaging the
transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to
normal operation.
NOTE:
Even if the transmission can be reset, we recommend that
you visit an authorized dealer at your earliest possible

Ú
convenience. An authorized dealer has diagnostic
equipment to assess the condition of your transmission. If
the transmission cannot be reset, authorized dealer
service is required.
AutoStick
AutoStick is a driver interactive transmission feature
providing manual shift control, giving you more control of
the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This feature can
also provide you with more control during passing, city
driving, cold slippery conditions, mountain driving, trailer
towing and many other situations.
Operation
When the gear selector is in the AutoStick position (beside
the DRIVE position), it can be moved forward and
rearward. This allows the driver to manually select the
transmission gear being used. Moving the gear selector
forward (-) triggers a downshift, and rearward (+) an
upshift. The current gear is displayed in the instrument
cluster.
NOTE:
In AutoStick mode, the transmission will only shift up or
down when the driver moves the gear selector rearward (+)
or forward (-), except as follows:
 The transmission will automatically upshift when
necessary to prevent engine overspeed.
 The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
