Admittedly I'm not an expert on the 4L70 but I at least thought that removing all TM would keep the timing from getting pulled between shifts like it does on the 6L80.
I attached two different version of tunes that I tried and a scan showing when it happens (frame 403).
Any and all suggestions are welcome.

Torque reduction still looks to be active for trans pattern X plus abuse mode tables look stock as well.Quote:
