sion may downshift out of Overdrive until the transmis-
sion cools down. After cool down, the transmission will
resume normal operation.
In high ambient temperatures with sustained high engine
speed and load, an upshift, followed shortly thereafter by
a downshift, may occur. The TOW/HAUL light will turn

strategy when operating in the TOW/HAUL mode.
The transmission will downshift from Overdrive, to the
most desirable gear, if the accelerator pedal is fully
depressed at vehicle speeds above approximately 35 mph
(56 km/h).

operating in TOW/HAUL mode, the transmission will
shift into direct gear and Overdrive will be enabled
under steady cruise conditions.
The “TOW/HAUL” indicator light will illuminate in the
instrument cluster to indicate when the switch has been
