Allison Transmission, Inc. has announced a new model in its 1000 Series transmission line. The 1350 transmission is a six-speed automatic transmission that offers a gross combination weight (GCW) of 30,000 lb., up from 26,000 lb. for previous models. It will be available in the company’s Highway Series (HS), Rugged Duty Series (RDS) Emergency Vehicle Series (EVS), Pupil Transport/Shuttle Series (PTS), Motorhome Series (MH) and the Specialty Series (SP) transmissions.
The 1350 transmission is also equipped with a park pawl, which Allison said means no air brake is required and simpler operation for the driver.
The 1350 transmission has been released in the International TerraStar truck as the exclusive transmission offering and with the Allison Optimized package, which includes Shift Energy Management (SEM), Low Range Torque Protection (LRTP), Load Based Shift Scheduling (LBSS), and Prognostics.
