Upgraded the torque conveter on 4l60e from a Yank ST3000 to a 10" TCI Super Streetfighter 4000 a lot looser stall. Now it takes 5-10miles of highway driving before TCC engages then after about 4miles it disengages for another 5-10miles. I have the tune here. Not sure exactly what PIDs to log if anyone wants a log of it.
04 Single cab Lq4/243 228r 112lsa, Long tubes, catless, Yank st3000.
Anyone have this same problem after upgrading to a looser stall?

Max your idle misfire tables. Setting the P0300 misfire table to no error reported doesn't stop the misfires from affecting the TCC lock-up.

Did you figure this out? I had a TCC issue before my SC install and haven't run mine yet to see if I could correct the problem.
There's two ways I have seen converters unlock. One is
the misfires. You can see this looking at 'TCC Mode' PID,
on the table display, a --3-- means lockup is inhibited by
misfires while Locked and Unlocked mean what you'd think.
Other way, which I found specifically on a TCI SF3000 in
some fouled-clutch distress, was from immature P1870
Transmission Component Slipping codes. Here, the slip
(unlocked fault response) would stay like that until the
next key cycle.
If it comes and goes repeatedly in a single drive, that
points at misfires. Slip once and then forever, that is
the crappy TCI clutch and only more pressure will help.
That's TCC Duty min value, and behind that probably
some tweaking of either force motor or general pressure
TCC adder, depending on what options your particular
OS*platform has offered.
