ABSTRACT:
A vehicle transmission assembly includes a main gear box that supports an auxiliary gear box assembly, such as a range gear box. The main gear box has a shaft that is coupled to a shaft of the range gear box assembly. The range gear box assembly includes selectively engageable range gears, a shifting assembly, and a range piston assembly. The range piston assembly includes a single piece housing, an air filter regulator, and a range position sensor. The sensor monitors range selection of the range gears and produces a range position signal that is sent to an electronic control unit. The air regulator is threadably attached to the single piece housing and provides air to a pneumatic piston that resides in the housing. The pneumatic piston is used to control the positioning of the range gears.
