35 mph WOT power loss

Update- after adjusting the last tiny bit of slack out of the line, flare up is pretty much all but eliminated... from stop to WOT 2 crisp shifts.

Light throttle driving around 35-40mph to WOT big bog. Like it is dying from being out of fuel or something...

That's really sweet and all but is it down shifting? It sounds to me like you BARELY have it adjusted in the most conservative acceptably spot possible. In other words, you need a lot more throttle pressure. Make sure the kickdown lever is all the way back as I described above. I don't think it is, because you keep finding "a little more" adjustment. Once you get the kickdown lever ALL THE WAY BACK AS FAR AS IT WILL GO when the pedal is on the floor, drive it and report back. I swear to GOD I thought we'd gone over this in another thread already. This is not something to take lightly and just "keep driving" around. You'll burn that transmission right on up.
