STARTING AND OPERATING 89
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
operati
ng 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.
Normal operation will resume once the
transmission temperature has risen to a suitable
level.
AutoStick
AutoStick is a driver-interactive transmission
f
eatur
e 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 system 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
(besid
e 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 d
own when the driver moves the gear
selector rearward (+) or forward (-), except as
described below:
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.
The transmission will automatically downshift to
FIRST or SECOND gear (depending on model)
when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as
the vehicle is accelerated.
You can start out (from a stop) in FIRST or
SECOND gear. Starting out in SECOND gear can
be helpful in snow or icy conditions. Tap the gear
selector forward or rearward to select the
desired gear after the vehicle is brought to a
stop.
If a requested downshift would cause the
engine to overspeed, that shift will not occur.
The system will ignore attempts to upshift at too
low of a vehicle speed.
Avoid using Cruise Control when AutoStick is
engaged because the transmission will not shift
automatically.
Transmission shifting will be more noticeable
when AutoStick is enabled.
The system may revert to automatic shift mode
if a fault or overheat condition is detected.
To disengage AutoStick mode, return the gear
selector to the DRIVE position. You can shift in or
out of the AutoStick position at any time without
taking your foot off the accelerator pedal.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.
