International integrates Allison transmission with S13

May 1, 2024
Allison’s 3414 Regional Haul Series and 4000 Series automatic transmissions now available to order in S13-equipped RH—a favorite for foodservice fleets—and HX trucks, respectively.

Allison Transmission’s 3414 Regional Haul Series (RHS) fully automatic transmission now is available in International Truck’s RH trucks—a favorite for wholesale food distributors, and regional food and beverage fleets—equipped with Navistar’s new S13 engine.

Additionally, the Allison 4000 Series transmission is available to order with S13-equipped International HX trucks, according to the OEM partners.

“We are proud to collaborate with International Truck to pair both the 3414 RHS and 4000 Series fully automatic transmissions with the Navistar S13 engine for an industry-leading driving experience,” Rohan Barua, Allison vice president of North America sales, global channel, and aftermarket, said in a news release. “Specifically, the 3414 RHS fully automatic transmission offers increased horsepower and a lighter weight, translating into more deliveries, more loads, and more productivity.”

With the combination of Allison’s fully automatic transmissions, International’s RH and HX platforms, and the Navistar S13 engine, customers now have two high-performance powertrain options with “superior acceleration and optimized efficiency,” the companies maintained.

The 3414 RHS transmission is designed to enhance vehicle handling and maneuverability in urban duty cycles, Allison added. It provides excellent performance and efficiency while improving fuel economy by up to 8% compared to the Allison 3000 Highway Series transmission. It also eliminates the downtime associated with automated manual transmissions (AMTs) by avoiding the need for clutch replacements.
