Kenworth has announced the availability of the 7-speed Allison 4700 Rugged Duty Series automatic transmission with the 116.5-in. BBC T880 short hood truck.
The Allison 4700 RDS is available with the PACCAR MX-13 engine as well as the PACCAR MX-11, which provides a 400-lb. weight savings over 13-liter engines. The transmission improves drivability, allowing truck operators to creep slowly and perform other low-speed maneuvers. This level of control makes the Allison 4700 RDS ideal for ready-mix applications where drivers require a truck with maximum speed control for job site maneuverability in steep and difficult terrain, or with mixer trucks that move slowly while pouring concrete for street curbs, driveways or other projects in confined spaces.
A lower first gear ratio and an optional second ‘deep reverse’ make the truck even more maneuverable particularly on steep grades and in tight settings. The rugged and durable Allison transmission also features no-power interrupts, providing full power shifts and allowing full use of the engine’s horsepower.
