I have a 2000 3500 A/T, and I am trying to do the APPS adjustment. This is after I've drilled/cleaned/lubed it. The problem is that I am getting 4. 35V with key on on orange/blu wire, then if I rotate the shaft slightly, it goes to . 427V. This . 427 is constant thru the shaft travel. The tag on the APPS has a value of . 455VDC. I am in need of feedback, as I don't want to purchase one if not needed (like everyone else) I also need a part # for a new APPS. I've been told it's a part # 4002066. # on the back of my old one is #56028184 - 9299RF? The reason for all of this is I would loose OD intermittenly, as well as lock-up issues. I have a TCI billet converter and a valve body kit installed w/gauges, Edge comp-4" ext & bhaf (just fyi) I am also gonna do a mystery switch for lock-up and a noise filter while im under the hood. Thx.
