Allison Transmission Inc. introduced its new 1350 model, which the company said will provide an option within its 1000 Series models for towing capacity of up to 30,000 lbs. 

The 1350 will be offered within the highway series, rugged duty series emergency vehicle series, pupil transport/shuttle series, motorhome series and the specialty series. 
 
Previously, the maximum gross combination weight approved in the Allison
1000 Series was 26,000 lbs. This new 1350 model increases that limit to 30,000 lbs. and
provides end users with increased towing capability. Additionally, the 1350 model comes equipped with a park pawl, meaning no air brake is required and the driver will
experience ease of use comparable to an automotive pick-up truck, the maker said. 
 
The 1350 model has been released in the International TerraStar truck as the exclusive transmission offering and with the Allison Optimized package, which includes shift energy management, low range torque protection, load-based shift scheduling, prognostics, and helps to conserve fuel, provide better acceleration and carry a load more efficiently, Allison added.
