This is kinda a dumb question, but can anyone give me a physical description or something that would allow me to ID a tranny as a NV4500 or not. The truck is a 93 chevy, with granny gear, but it is a 1/2 ton (though it has all the towing goodies like heavier rear springs, etc.). The reason I ask is a mechnic friend swears the tranny is a NV4500, and there is the # 4500 stamped onto the tag on one of the little covers on the side. So I'm curious.
