Hello, I have been seeing an issue where the 3->4 shift will unlock during WOT runs and not command lockup when it's supposed to. It was happening since I got to the track and I made about 5 passes trying various thing such as setting the lockup speed to 1MPH. That did not work, so we did a fast relearn and the car started to lockup again and was fine for about 10 passes in a row, although the shifts were all over the place and needed a few passes to relearn. However, it started to do the same thing again towards the end of the night on my last several passes.
Another thing I also noticed is that when the TCC apply is acting up, 2nd gear will also get commanded too late whereas when it's running perfectly, it will lockup 2nd gear almost immedately after the shift completes and holds it through the run. When it locks perfect, it's running 10.48 vs 10.65 when it's not.
