6L80 5-6 Gear Shifting Unlock

Hey,
does anyone has the answer on that question?

In HPTuners the unlock isnt available, and I don't have the knowledge to get deep in the code.

It must have something to do with the VSS Out on tranny, because the shift point changes, when the diff is changed to 3.73 ....even a change, when the software for that gears are uploaded.

It sucks, I only get up to 260kmh....then no shifting into 6th.

Have you had the trans tuned ? Or you just put in New gear info only. The mph shift may be to high . pm me I'll look trans file over.

Its a known problem.
The 6th gear should not be used for high speed, so it's locked.
with short reduced diff I need the 6th.
Software is set to 3.73 and all shift points are changed and checked.
