your WOT shift speed and 100% tps values do not match?

No, but what in the transmission would feedback to the PCM and cause it to pull throttle? 1-2 shift is rock solid and quick everywhere else.... up to WOT

Nope they don't. One of the things I've tried changing to see if it did anything. They did match before. Putting it back.

have you tried zeroing the shift speed and relying solely on rpm?

Haven't tried. I will. Thanks. That was one of the reasons I tried dropping from 40 to 33... to be sure I was meeting that condition.
