range 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 opera-
tion 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 maxi-
mum efficiency. Engagement of the torque con-
verter clutch, and shifts into 8th or 9th gear, are
inhibited until the transmission fluid is warm
(refer to the “Note” under “Torque Converter
Clutch” in this section). Normal operation will
resume once the 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 avail-
able engine power.
SPORT mode is activated using the rotary
switch on the center console. Refer to
"
Selec-
Terrain
"
in this section for further information.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition is
detected that could result in transmission dam-
age, Transmission Limp Home Mode is acti-
vated. In this mode, the transmission remains in
fourth gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will
continue to operate. The Malfunction Indicator
Light (MIL) may be illuminated. Limp Home
Mode allows 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 switch to the LOCK/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 transmis-
sion will return to normal operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit your authorized
dealer at your earliest possible conve-
nience. Your authorized dealer has diagnos-
tic equipment to determine if the problem
could recur. If the transmission cannot be
reset, authorized dealer service is required.
