If the transmission temperature exceeds normal operat-

ing limits, the powertrain controller will modify the

transmission shift schedule and expand the range of

torque converter clutch engagement. This is done to

prevent transmission damage due to overheating.
During cold temperatures, transmission operation may

be modified depending on engine and transmission

temperature as well as vehicle speed. This feature im-

proves warm up time of the engine and transmission to

achieve maximum efficiency. Engagement of the torque

converter clutch is inhibited until the transmission fluid

is warm (refer to the “Note” under “Torque Converter

Clutch” in this section). During extremely cold tempera-

tures (-16°F [-27°C] or below), operation may briefly be

limited to only second gear (for four-speed transmission)

or third gear (for six-speed transmission). Normal opera-

tion will resume once the transmission temperature has

risen to a suitable level.

Transmission Limp Home Mode
Transmission function is monitored electronically for

abnormal conditions. If a condition is detected that could

result in transmission damage, Transmission Limp Home

Mode is activated. In this mode, the transmission remains

in second gear (for four-speed transmission) or third gear

(for six-speed transmission) 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.
