Kenworth adds Allison LBSS
as select transmission feature
Oct 7, 2009 1:45 PM
Kenworth Truck Company now offers Allison Transmissionís Load-Based Shift Scheduling (LBSS) as a standard feature on select Allison transmissions with Kenworth Class 8 and medium-duty trucks for enhanced fuel economy and performance.
Allison LBSS is included on the companyís fully automatic Highway Series (HS) and Rugged Duty Series (RDS) transmissions when configured with a 2007 and later emission model engine. LBSS automatically selects between economy and performance shift schedules based on the vehicleís actual payload and its operating grade. The economy mode is used when the truck travels on level terrain with an empty or diminishing load. The performance mode is used when the vehicle is heavily loaded or on a grade. According to Allison, the system can help enhance fuel economy while maintaining high productivity, even during heavily loaded situations.
The addition of LBSS to Allison 3000 and 4000 series models can allow the mode button on the transmissionís shift selector to be programmed for controlling other vehicle functions, such as body builder functions or power take-off (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.
