Eaton’s automated UltraShift HV (Highway Value) medium-duty transmissions are now available with a new park pawl option that simplifies driving and, says the company, helps
promote safe operation. When engaged, it securely locks the transmission, and simultaneously the vehicle’s drivetrain and driven wheels, to ensure that the vehicle remains stationary when parked.

The new option is expected to be especially popular for drivers without a commercial driving licence because it creates a driving environment more like that of a car. It’s only available for medium-duty applications for class 6 vehicles with GCW ratings up to 26,000 lb.

UltraShift HV models with the park pawl option require an OEM-supplied shifter that replaces the standard pushbutton shift console. It also features the ability to engage the
hold mode in any gear for continuous operation on a variety of grades.
