A parking brake and transmission interlock system including a transmission control element (30) movable between at least two opposed drive positions and an intermediate neutral position, a parking brake control element (14-22) movable between engaged and disengaged positions, a stop (36) having two stop surfaces (38,40) connected to the transmission control element (30), to be movable therewith between the drive and neutral positions, a pair of movably mounted abutments (52,56) each confronting a respective one of the stop surfaces (38,40) and engageable therewith, a spring (58) biasing each of the abutments (52,56) toward its associated stop surface (38,40) to engage the same and urge the stop (36) toward the neutral position, and a fluid motor (64) responsive to the positioning of the brake control element (14-22) in the disengaged position for moving the abutments (52,56) away from the associated stop surfaces (38,40) so that the transmission control element (30) may be freely moved between the drive and neutral positions.
