gear will improve performance and extend trans-
mission life by reducing excessive shifting and
heat buildup.
If the transmission temperature exceeds normal
operating limits, the transmission controller will
modify the transmission shift schedule and ex-
pand the range of torque converter clutch en-
gagement. 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 very cold temperatures (-4°F [-20°C] or
below), transmission operation may be modified
depending on engine and transmission tem-
perature as well as vehicle speed. Normal op-
eration will resume once the transmission tem-
perature has risen to a suitable level.
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
162
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 transmission
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.
Overdrive Operation
The automatic transmission includes an elec-
tronically controlled Overdrive (sixth gear). The
transmission will automatically shift into Over-
drive if the following conditions are present:
• the shift lever is in the DRIVE position,
• the transmission fluid has reached an ad-
equate temperature,
• the engine coolant has reached an adequate
temperature,
• vehicle speed is sufficiently high, and
• the driver is not heavily pressing the
accelerator.
