    6.0 Powerstroke TCC Lockup

    Anyone had success on TCC Lockup on decel? After you let off the throttle tcc unlock withing about a second no matter where I set lockup to stay engaged until.

    Am I missing something or is there something missing in software?

    Are you hitting the brake? Sounds like a stupid question but that pretty normal behavior you're seeing. No lockup on decel is normal across pretty much everything.

    Yes there are a few tables you need to adjust to keep the TC locked on decel. Some early trucks dont react the same as the 05-07
