Hey guys I a from a diffrent parts of the forums here for a visit and hoping you guys can answer the question that my hometown forum folks have no ideas on......I have a 12 valve cummins in my slverado but also have a 2004 48re, I have found 2 companies that sell electronic valve bodys that will allow a stand alone computer to control the tranie. I am looking on input about what one to pick....suncoast or ATS. Help is appreciated.
