Abstract
Provided is a transmission gear change shift bar housing assembly (100) that features a pair of shift bars (18, 24) respectively slidably disposed within bores (7, 9) in a housing (4) that are respectively attached to pistons (14, 22) that respectively define fluid pressurizable chambers (A, B and D) with chambers (A) and (D) being in fluid communication with each other in conjunction with and end housing (38) having an enlarged fluid pressurizable chamber (C) containing an enlarged piston (42) engagable with piston (14) and a fluid pressurizable chamber (E) in fluid communication with piston (22) such that selective pressurization of one or more of chambers (A, B, C, D and E) is able to move shift bar (18) between a neutral position (N) and two axial displaced positions (P.sub.1, P.sub.2) and to move shift bar (24) between a neutral position (N) and an axially displaced position (P) with enlarged piston (42) and chamber (C) operative to apply increased force against piston (14) for effecting rapid and positive shifting.
