To meet the needs of those seeking increased towing capacity, Allison Transmission has released the 1350 model, an addition to its 1000 Series line.

The 1350 offers towing capacity of up to 30,000 lbs, Allison said. Previously, 1000 Series models had a maximum gross combination weight (GCW) towing capacity of 26,000 lbs. It will be offered within the Highway Series (HS), Rugged Duty Series (RDS) Emergency Vehicle Series (EVS), Pupil Transport/Shuttle Series (PTS), Motorhome Series (MH) and the Specialty Series (SP).

Also included in the new transmission is a “park pawl,” which means that no air brake is required and the driver will experience ease of use comparable to an automotive pickup truck transmission, Allison said.

The 1350 model has been released in the International TerraStar truck as the exclusive transmission offering and with the Allison Optimized package. The Allison Optimized package, which includes shift energy management (SEM), low range torque protection (LRTP), load based shift scheduling (LBSS), and prognostics, helps to conserve fuel, provide better acceleration and carry a load more efficiently.
