truck not shifting under boost

[MidnightRider]

I believe the consensus was that the tune is not responsible for blowing a trans because of a high idle as posted in another thread. Of course a crappy tune can hurt a trans. Then again, I know one person here that has lost 4th seven times in six months and his builder is supposed to be great.

his builder is great and has a proven tranny. Do you even know whats going on with the tune in that truck or are you just flying off at the mouth. Btw Greg went threw it 4 times in a short time as well. AFA you tranny goes it may be taking a dump. If you have friction particles in you valve body, sylinoids, filters its not going to shift right also it could be the converter flairing and if it is then you definatley got trash in it. Sounds like its time for a built unit and new verter
