Daimler Trucks North America offers a new Allison transmission in Class 9 Freightliner Cascadia: the 3414 Regional Haul Series (RHS.) Freightliner is now taking orders for trucks with the Allison 3414 RHS, with production slated to start in January 2022. These transmissions can be paired with the Detroit DD13 Gen 5 engine, rated for 410 HP and 1,450 lb-ft. of torque.

 This new Regional Haul Series gearbox is an updated version of the 3000 Highway Series automatic transmission. Last year, the 3414 RHS was recognized as one of Heavy Duty Trucking’s Top 20 Products. Allison says the 3414 offers 8% better fuel economy compared to the 3000 while providing 25% better acceleration from 0-20 MPH than an equivalent automated manual transmission. It’s also 11% lighter than the subsequent most lightweight transmission in this segment, freeing up a weight that can be used for the payload. According to the company, this makes the 3414 ideal for routes requiring frequent stop-start duty cycles and in mixed regional and local use, increasing loads and productivity. Mary Aufdemberg, general manager of product strategy and market development for DTNA, says RHS-equipped trucks are a “winning combination for weight-conscious segments where acceleration and maneuverability are also critical.”

 This new Allison transmission uses the same case shape, mounts, and connections as the 3000, so it should be a drop-in replacement for chassis that use the older transmission. It also comes with the same five years / 750,000-mile warranty as to the 3000. This coverage includes towing, and there are no exceptions for individual components.
