Operation
Engine Overspeed Protection
•
The transmission system will automatically Upshift if necessary to pre-
vent engine overspeed in Drive, MANUAL and LOW modes.
Shuttle Shifting
•
Shuttle shifting the transmission system between a forward or reverse
mode is allowed if the vehicle speed is approximately 2 MPH or less.
Smart Gear Selection
•
Smart Gear Selection automatically selects the appropriate forward or
reverse start gear based on vehicle operating conditions such as:
grade, load, and vehicle weight.
•
The driver can change the start gear by manually Upshifting or Down-
shifting to the desired gear using the transmission driver interface
device. Refer to OEM transmission driver interface device instructions.
Note:
If the transmission system determines the manually requested
start gear is not appropriate based on vehicle operating conditions an
audible tone is emitted and the gear selection is not allowed.
Note:
Minimum and maximum manual start gear selections are config-
ured in the Transmission Control Module (TCM) using ServiceRanger.
•
The transmission system will automatically perform "Skip shifting" if
the system determines vehicle operating conditions such as: grade,
vehicle weight, engine torque and driver demand are within limits that
allow for proper gear engagement and vehicle operation.
