Kenworth T470, T800: Powertrain

Affects Kenworth T470, T800 · 2014 — about 8 vehicles.

The hazard

On certain trucks equipped with an Allison automatic transmission, the neutral start switch may have been incorrectly programmed during vehicle assembly. As such, the engine may be started when the transmission is in gear, which would allow the vehicle to move unexpectedly. This could result in property damage, or cause the vehicle to strike a bystander, potentially resulting in personal injury. Correction: Dealers will reprogram the Cab Electrical Control Unit to enable the start-in-gear protection feature.
