ABSTRACT:
A powertrain including an engine and attached power transmission means has a stiffening bracket extending between the side walls of the engine block and the transmission means housing. The bracket extends under and separate from the engine oil pan and has integral ribs depending from a floor and extending longitudinally and diagonally from the power transmission connections to each of the side wall connections to add both bending and torsional stiffness to the powertrain, thus reducing vibration, noise and stress.
