Operation
Coast Mode
•
Coast Mode prevents the transmission system from downshifting
through each lower gear when the driver is bringing the vehicle to a
stop. If the transmission system determines the vehicle is coasting and
is in a gear below the Coast Down Gear configured in the Transmission
Control Module (TCM), the transmission system will automatically shift
into a neutral state, allowing the vehicle to roll uninterrupted as the
driver brings it to a stop. Once stopped, the transmission system auto-
matically shifts into an appropriate start gear.
•
If the driver depresses the accelerator pedal during a Coast Mode
event, the transmission system will shift into an appropriate gear posi-
tion for the current vehicle operating conditions.
Note:
The Coast Down Gear is configured in the Transmission Control
Module (TCM) at the OEM. The configuration can be changed using Ser-
viceRanger.
