shifts at 5900 no mater what i do .
it also upshifts at 5900 in autostick.
It is a new trans and engine ,engine makes 650 hp at 6800 rpm na.
if i do by chance get it to 6500 the trans goes in limp mode( all neutral)
the tq reduction on shifts is also random it seams to work below 5400 rpm but not above .
does anyone know why various rpms and other data on data record do not match for example vss on graph is 71 on channels it is 67?
