Kenworth Class 8 and medium-duty trucks are now available with Allison Transmission's Load-Based Shift Scheduling as a standard feature on select Allison transmissions.


LBSS automatically selects between economy and performance shift schedules based on the vehicle's actual payload and the grade on which it is operating. This optimizes fuel economy while maintaining high productivity capability, even during heavily loaded situations.

Using advanced algorithms to calculate real-time vehicle load and operating grade, LBSS selects the appropriate shift schedule for the task at hand. It is calibrated to primarily use the Economy mode, but automatically selects the performance mode when conditions require it. LBSS is part of the standard Shift Energy Management (SEM) calibration for approved engines.

On trucks with Allison 3000 and 4000 series models, the LBSS allows the mode button on the transmission's shift selector to be programmed for controlling other vehicle functions, such as body builder functions or power takeoff (PTO) operation.

On trucks with Allison 1000 and 2000 series transmissions without a shift schedule dash switch, LBSS automatically performs the shift schedule selection for the driver, eliminating the need to manually select the transmission shift schedule for economy operation.
