output in order to protect driveline components when the drivetrain reduction is
calculated to be above a calibrated ratio.

Feature Options
Driveline Protection
Driveline Protection allows the engine to reduce the maximum available torque to
950 lbf-ft when it detects a transmission gear reduction greater than the calibrated
value. This functionality provides the rated torque in all conditions, and only reduces
torque output if one or both of the following conditions are met:
The vehicle has an auxiliary transmission with gear ratio greater than 1.0:1
Vehicle has a transmission in a forward or reverse gear with a gear ratio
equal to or greater than 13.0:1
Driveline protection is automatically included within the programming for all multi-
torque engine ratings, as it utilizes the same software functions to enable the higher
torque values of the multi-torque rating.
