This control is used on Allison's transmissions that have a 2nd neutral position beyond reverse and no internal parking pawl mechanism. Movement of the shift selector from reverse to the "PB" position will shift the transmission into 2nd neutral and actuate the vehicle Spring Parking Brake system control.
In the mechanical control, brake actuation is accomplished through a push/pull cable. In the electrical control, brake actuation is accomplished through an electrical switch.
The shift position indicator reads "PB R N D D3 D1".
