Cold Operation (8-Cylinder Pickup
Models Only)
When temperatures are very cold,
the transmission will prevent certain
operations to protect against
damage. The information below
shows shift range availability based
on transmission oil temperature:
All shift ranges available at 25 °
C ( 13 °F) or above.
2 (Second) and 3 (Third) shift
ranges only at 35 °C ( 31 °F) to
25 °C ( 13 °F).
2 (Second) shift range only at
35 °C ( 31 °F) or lower.
Torque converter clutch operation
will also be prevented when air or
transmission oil temperatures are
below certain levels.

Adaptive Shift Controls
(8-Cylinder Pickup Models Only)
The shift quality of a new vehicle
may not be ideal because the
Adaptive Shift Control process may
not have determined the best
settings for a particular shift or
condition. Shift quality will improve
with continued driving.
Low Traction Mode (8-Cylinder
and 4-Cylinder Pickup
Models Only)
Low Traction Mode aids in vehicle
acceleration on slippery road
surfaces such as ice or snow. By
selecting 2 (Second) using Range
Selection Mode while at a stop, the
transmission will limit torque to the
drive wheels to prevent slippage.
