Message: [QUOTE="timj, post: 1322340, member: 14399"] I have what seems to be the exact problem. Anything over 3/4 throttle going from 3 to 5 shift it won't shift to 5th (aka 4th). It will free rev and because of the free rev it completely de-fuel for 1.5 seconds. Just like you shut the key off for 1.5 seconds. If I stay in it, after that 1.5 second period, (and scraping my face off the windshield) rpms come right back to life, shift to 4th lock, 5th/aka 6th o.d, 5th lock no problem. Anything under 3/4 throttle it doesn't act up. I built my own trans so I tore it back down. All clutches looked like new except directs had just a touch of wear and started getting hot so I put a new set of directs in. Checked the direct apply piston and swapped out the direct solenoid for another stock one from my spare trans. Tried various different tunes but no change. Just speculating but going to swap the whole valve body. If no change pull trans apart and swap the center support from my other trans. I hate to do it that way but it happens so fast and abruptly that it's hard to even watch trans pressures to see what's happening. [/QUOTE]
