Need help! - Car won't shift to 3rd at WOT
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.
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.

Note that the indicator at the trans base was showing the D but the PCM was not (N).
