A transmission neutralizing system for a vehicle includes a transmission control mechanism (28) movable between at least two opposed drive positions and an intermediate neutral position. The transmission control mechanism (28) has an arm and roller combination (60, 70) movable therewith and a control element (72) movable between engaged and disengaged positions. The control element (72) has an arcuate cam surface (73) to engage the roller (70) and urge the transmission control mechanism (28) toward the neutral position when the vehicle parking brake (8) is engaged. A fluid motor (76) responsive to fluid pressure in the parking brake circuit (8) moves the control element (72) to a disengaged position against the bias of a spring (84) to allow free movement of the transmission shift control mechanism (28) between the neutral and drive positions, when the vehicle parking brake (8) is disengaged. |
