Cold Operation
(Allison Transmission)
When temperatures are very cold,
the transmission will prevent certain
operations to protect against
damage. The chart 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.
For areas where ambient
temperatures are below
−
40 C (
−
40 F), use synthetic
transmission fluid approved to
Allison Transmission specification

Adaptive Shift Controls
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
(Allison Transmission)
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.
