Specifically designed for the Allison 1000/2000 Park Pawl trnasmission.

Probably not something we would install on our trucks but the information is interesting. Basically it's an electronic shifter that mounts where our cable, NSBU switch is. In the cab you have an electronic shift controller.

"The primary components of the electric shift system consist of a pushbutton range selector, Electric Shifter Interface (ESI) module, and an integrated Electromechanical Solenoid Firing (ESF) module / solenoid actuated transmission station.

The transmission station is easily installed onto the transmission. It is bolted onto the transmission with an accompanying bracket and linkage and lever to the selector shaft. The mounting envelope of the shifter does not interfere with the NSBU or the PTO mounting pads. Power and interface connections are made with environmentally sealed, over-molded connectors which maintain the IP67 sealing characteristics of the system."
