06 TBSS. Has a built trans and a yank 3000. Shifts fine at part throttle but will not shift 1-2 at WOT. I set the rpm and mph ridiculously low but still no luck. The scanner shows the shift is commanding, its just not happening. Please help.
NO SHIFT.hpl
modded 4.hpt
Also, after a rewrite entire/ letting the vehicle cool down, it seems the first time we try for a 1-2 it will actually happen. But after that it's no luck.
