Fast 4.7,..I just re-read my post,...simply inexcusable for me not to respond to you,.... big apologies for that bud. As self-punishment,...no cold beer for me tonight after working on truck today (well,...........maybe).
Yes Sir, after I verified the scanner commanded/actual was operating from the PCM to PCS (by reading what was commanded from "Controls and Special Functions" versus "actual" being recording on the scanner), I next checked resistance of the PCS,... and found it good at 4.7ohms (spec is 3-7ohms). I then unplugged the main wiring harness connector from the transmission and fired that dude up,..... Gauge didn't move at all,...stayed right at the same ~84#,...thus, I know its not a bad PCS,...it's gotta be a mechanical issue inside transmission.
When I drain/drop the pan today to swap the 1-2/2-3 shift solenoid connectors back around (as they were originally), and proceed with retesting it all per Bill@HPTuners 3.6 software update suggestion above,... I'll go ahead and pull the PCS/ all valves to inspect/cycle them manually to assure none are bound up or something. Is there anything else I should inspect while I'm there? I thought about also checking the boost valve to assure it not stuck/moves freely,.....kinda sucks because this is a new beefed up transmission with only 363 miles on it (it's a local build/not the FLT trans in my signature,...I'm waiting to assure all the bugs are gone from this one before I install that nice FLT trans,....if the local built trans last long enough).
Thanks Fast4.7, and the rest of you guys for reading and helping the next guy.
