just a real basic one direction question that the all mighty intra net cant help me with. I am about to swap the motor in a 2002 alero 3.4l. i was given a motor but its out of a 2001 alero 3.4l standard, mine's an auto. wondering if the manual motor will bolt up to the auto tranny, Mainly the crank is what i'm concerned about, if it needs to be drilled or anything. i doubt them ecm would effect anything since its just the motor i'm changing, nothing else. thank you
