    I can see the problem, but part of the run is not WOT, so it's hard to pinpoint what's causing the problem. As mentioned above, you need to log some trans pids. Change the WOT 2>3 Shift rpm to 6400 rpm so it matches the 1>2 shift. Have someone drive the car so you can use the DVT controls to see if you can force the 2>3 shift. Make sure it's WOT from launch if possible. This will help to see if it's mechanical or not.
