I have a 2002 Dakota 4x4 with a 4.7L 4 speed automatic, will a 5 speed auto out of a 03 or 04 work in it? I get theyll bolt right up but will the on board computer handle the 5 speed? Was wondering if I could swap it out for the 5 speed and be able to drop the revs down up on the highway with that extra OD gear they got in 03.
