Need help! - Car won't shift to 3rd at WOT
A4 tranny, of course. I've tried everything to get it to shift from 2-3 at WOT. No go. Just now tried lowering the shift RPMs and shift MPH to around 6200rpm while raising the Fuel Cutoff to 6800rpm. Put it in 2nd, drove it to above the 2-1 kickdown, punched it, shifted to "3" and it revved right up to 6800 where it hit the fuel cutoff.
I was looking for the "commanded shift" point with HP Tuners, but can't find it. Any clue which signal I need to be logging?
Could it be something as simple as the 2-3 solenoid giving up the ghost or something worse?
The car still drives great at part-throttle and seems to shift fine at part-throttle.
It should be noted that it shifted fine before with the current tune. This just started......Log attached.
Thanks for any help/advice.

I already tried playing with the shift settings. Car has the same mods as it has for awhile...but the weather is colder so it's making more power in that aspect.
Very frustrating. I'm thinking it's something in the tranny but would like to find a way to make sure before i spent 2k plus labor.

probably would effect all shift points, or so it did in my case, i was just throwing s imple check that took me WEEKs to find. its in the engine bay fuse box, should be labeled, its a 20a fuse.

It happend to me before, I found that the position indicator is faulty, if I select D it reads N, if D3 it reads D...etc. Check that too
Note that the indicator at the trans base was showing the D but the PCM was not (N).
