    So far the Ally Locker from FPE has been the only fix I have found to get them to lock up when they need to. Several of my customer's with high horsepower pulling trucks with Copilots wouldn't lock the convertor till half track when the load dropped. Would be nice to have this in the TCM tuning but until then the Ally Locker is getting the job done.

    I would buy one of those before I would buy a co-pilot, but I can't find a price on FPE's website. How much are they? I would guess around $500, and like Ben said, it would be my luck that the tables would be discovered and released and make the new toy obsolete.

    The Co-Pilot is not a cure for lock-up issues on LBZ trucks with loose converters. The Ally Locker has worked well on my truck but It would still be very benefical to have the ability to work with the tables in question.

    Line pressure is mechanically fixed with a spring. The only way to change it or raise it is with a shim on the stock spring(Suncoast) or change to a heavier spring like the one ATS sells. Ford transmissions have the ability to raise or lower the line pressure electronically which is cool, that's one of the reasons the 6.4 trucks don't have to do trans mods before they add power.

    Bump to the top to beg some more. Please guys, Pretty please can you look for the table to help us out.

    Thanks

    Ross let me know if you need me to log anything/test anything as well for 5-speed stuff...ive been battling this issue for years and know the allison TCM's lockup inhibit quirks inside and out.

    Just so I am clear on this, we have the TCC apply tables v's throttle. Are you saying that these are getting bypassed based on some slip ratio the TCM calculates?

    There is an additional "override" table that dictates if turbine vs. input speed difference (slip) is over 600rpm, the TCM will not lock the converter. It doesnt care if D5010 and D5013 are set to 2mph or 200mph, if tcc slip rpm is over 600, its NOT going to lock.

    This is from one of Ben's posts. Ben will be better at explaining it in detail. Hope this helps.
    Thanks, Randy
