hey out there just wanted to drop a line to let everyone know we are developing a 4l80e which will use a 2004r valve body and an aluminum transfer plate to allow it to be a hydraulic shift automatic trans with no computer neccessary.road speed output shaft signal will be via a epc controlled by engine rpm if a governor cant be retro fitted on the ass end.i will do this or die trying.anyone out there think this is something they would like to see/?any input?of course it is going to be lightened.
