Abstract
An input brake assembly is provided for selectively grounding a transmission input member. The packaging location of the input brake assembly does not interfere with, and thus still allows the option of providing a bypass clutch for a flex plate-type flywheel connecting the engine with the transmission input member. The input brake assembly includes a flywheel, preferably a flex plate, for transferring rotary torque between the engine and the transmission input member and a ring gear secured to the outer periphery of the flex plate. A pinion gear is axially movable into and out of meshing engagement with the ring gear. A grounding device is operatively connected to the pinion gear and is operable to prevent rotation of the pinion gear, thereby braking the flex plate as well as the transmission input member operatively connected thereto when the pinion gear is in meshing engagement with the ring gear.
