ABSTRACT:
An improved fluid operated (X-Y) shifting mechanism (100) is provided for shifting gears or clutches of a mechanical change gear transmission. Mechanism (100) features a shift finger (14) that is secured to a shaft (6) that is moved in an axial (Y--Y) direction by at least one piston (28) and is pivoted in a substantially transverse (X--X) direction by at least one piston (12) having a bore (10) in which an end of shaft (6) is supported and operative to rotate relative thereto to substantially lessen rotational inertia in encountered shifting in the (X--X) direction particularly during cold weather.
