    Yeh, that is my thoughts too...the tunes. I can't really REMOVE the tunes cause I replaced my split-shots with single-shot have to have some tunes for the engine to run right. But, I will try some of the original tunes I got. So, you don't think this is a valve body issue? or clogged filter? or TC? 1 other symptom is it seems to slip for a second btwn 1-2nd...usually more so when warmed up......again PHP says that isn't their issue, but a tranny issue. They said they even removed the "delay" setting.

    Mr Mark, Hello, sir. What would cause not shifting to the next gear at WOT or anywhere near it? 2002 Excursion 7.3L, 37" tires, Jasper rebuilt sometime ago 4R100 with John Woody Valve Body, running PHP Tunes. PHP swears it isn't there tunes & that it is already programmed with 1-3mph sooner shifting. There is no slipping even when towing, no codes, runs great & powerful at all other times....just won't shift to next gear near or at WOT (even when get to 3200+ RPM's)....yes, I know, that is basically redlining it, which is why I want to fix it. Any help would be much appreciated, sir. Jeff

    Hi mark ,
    I have the od light flashing , & 4way hazard switch deactivating od when pressed while running.
    Its a 94 f250 e4od 7.3 idi.(2 Unnecessary builds) I researched down to the Psom chip , which fixed the slamming shifting problem originally.
    Od light still flashes and the 4way switch kicks out overdrive causing high rpm. I read about reprogramming the Psom or something for that brake voltage fix ?! How do I do that. I have an older scanner?! HaHa.
    I'm recuperating from an accident and my employer of 28yrs seem to not want me anymore, I'm kinda unable and disabled .SO.....
    Can I: fix this myself, operate the truck w/out causing more damage.
    Truck has 230k miles +- and electric trailer brake hook Up.
    I'm going to do the dielectric grease and connector cleanse thing. Most all sensors were changed as I stumbled with shift slamming issue. ANY info would be very helpful.
    Thanks In advance.
    I have found that being disabled and unemployed is a full time job. Ha"!

    Is this a Taurus? Focus? F-150? Explorer? Escape? Corvette? Tesla? Model "T"? Ferrari? You have to give me something to start with. All I can tell you at this point is that you're losing fluid somewhere.
