    I take it you have suitable supporting hard parts and hydraulic parts (shift kit).

    If he does 3rd gear only, it should only strain the converter right? It'll shift 2-3 unlocked then lock a second later.

    Joe, why wouldn't I keep the 120 if that's the speed I want the converter to lock at WOT?

    That's not how this table works... but try zeroing it anyway... if it does not work, set it back to 100%.

    The idea is to bring it down to 68 and see if it locks... if it does now lock, then bump it up to 88 and see if it locks... continue testing/bumping up until you get to 120.

    Do you have any logs containing the pids VSS, RPM, TP, GEAR, TCCMODE, TCCSLIP, TCCDC, SHIFTLAST, TFMPRS, TFT...

    keep the pid channel count to 24 or lower since we want to see highest sample rate.
