Using a TCI 37700box and a 4l80E.

When TCC applies the whole transmission/car starts to "hesitate"....
I spoke to the guy who built the 4L80E ha said I should set the TCC to on/off. How do I do that in the TCI box?

I tried to set Lockup rate to 255 but car still hesitates......

Can I hook up C8 on TCU to C10 (tcc 4L60) instead of C9 (tcc 4L80e) and get the tcc to act like on a 4L60E on/off function without damage transmission or TCU?

TCC line pressure moves from 0-80 when locking, is that normal?

hesitations begins when lineprssure is about 60......
