A method and apparatus for adapting powertrain braking to mass, grade, and brake temperature. The image sensor may include an electron collecting device formed in the semiconductor substrate to receive at least a portion of the electrons generated by the light in the light receiving device. A gear case with a plate portion and a skirt is clamped to the vertical plate to form a sealed gear case. To insure that the proper body type is being produced, the assembly plant controller verifies the version of the sheet metal component by using a plurality of sensors.
