Just a hunch......did you double check clutch clearances? These need to be a bit looser than you think or the specs say. Be patient with finding the right steel and clutch plate combo. It will burn up the bands quickly and cause first and third, fourth applications to go away and give you the funkiest shift or non shift problems. Do it again and loosen them up by at least .020". Don't forget to thouroghly clean the valve body again. Light sediments will come back to haunt you from your described conditons.

The tranny has been slipping for a while now, long before I did the servo. I put it in last summer and it worked a little better. At the end of the drag season it was starting to slip rather much, in all gears It still shifted properly, under low load, you could feel it change gears but it just wasn't able to hold my sbc. And yes the throttle pressure valve was set properly. I'm rebuilding the engine this year and its going to be considerably more potent, I just want to rebuild the tranny before any major failures. Not to mention I will be running a muck higher stall this year also (3200-3600). My question really is, what would be the best rebuild kit for the job. That is to redo the entire transmission, and which parts should be replaced with those of increased strenght.

The link I posted goes into every single piece of the transmission in detail and exsplains what materials are best for your exact engine ,not just some kit.You can get every single piece individualy,based on your combo .The site goes into more exsplainations of parts what hp and torque they fail at and why,than any manual you could purchase.
Buy what you want from wherever you want.........but this site will educate you on exactly whats available and why.

That site does have alot of info, Thanks!!! A little outa my price range tho.
