A magnetic brake for a transmission lock includes a coil housing having a closed end, an open end, and a continuous side wall therebetween. A central post extends from the closed end of the housing and establishes an annular chamber between the central post and the side wall, and a coil surrounds the post. A frusto-conical brake plate seat circumscribes the open end of the housing. A brake plate has frusto-conical peripheral surface, and when the coil is energized, the surface engages the seat in an interference fit that is sufficiently tight to prevent the brake plate from being rotated relative to the housing. A spring washer is included to bias the brake plate from the locked position to the unlocked position.
