Allison Transmission‘s 2500 Rugged Duty SeriesTM (RDS) six-speed fully automatic transmission has been integrated into Isuzu Commercial Truck of America’s first F-Series Class 7 truck model. In addition, Isuzu’s new F-Series Class 6 truck model will feature Allison’s 2550 RDS six-speed fully automatic transmission. Both vehicles are now in serial production. Allison’s 2500 and 2550 RDS transmissions, with available FuelSense 2.0 software, will be paired with the Cummins B6.7 diesel engine.

The Allison 2500 without park pawl has been integrated in the Class 7 capable Isuzu FVR model. The Allison 2550 with park pawl has been integrated in the Class 6 FTR model. The powertrain is engineered to provide the optimum blend of power that drivers demand with good fuel economy and reliability, the company says.

Isuzu has begun production of its 2022 F-Series Class 6 and Class 7 trucks, exclusively with the Allison fully automatic transmission and featuring a low cab forward design that provides more cargo capacity versus conventional cab competitors with a comparable wheelbase. Allison fully automatics are also available on Isuzu’s N-Series Class 5 truck models.

The 2022 Isuzu F-Series is available at Isuzu’s network of over 300 dealerships.
