Abstract
A brake-transmission shift interlock device for an automatic transmission system includes a solenoid secured to a support member that positions the solenoid so as to block movement of a transmission member to prevent a transmission shifter from being moved from a park position. The solenoid includes a plunger having first and second portions and . The second plunger portion engages the transmission member laterally on a side wall if the brake pedal is not depressed and the shifter is in the park position. To prevent the plunger from binding, the second plunger portion is allowed to axially offset from the first plunger portion thereby reducing the required lineal force to move the plunger from a first to a second position when the solenoid is energized.
