Default Turbo 350 shifting out of 3rd when gets warm

I have a 79 chevy truck with a 454 built to a 468 with a turbo 350 and np 208 tc. it shifts prefectly fine when cold. when tranny gets to operating temp it takes a lot longer to shift into third gear. and when it finally does i will be driving and at random times it will just downshift into second. i will shift into neutral (while going dow the road still) and shift back into drive and it will be in third, then a few minutes later it will do it again. it slowly gets worse the longer i drive it. i dont know if it has something to do with the modulator, i dont know much about trannys. the kickdown cable is adjusted correctly. i do have an aftermarket cooler in front of the radiator, and yes the tranny fluid is right at the top of the full mark. any ideas?!?!?!

It may only need a set of teflon rings. I don't know if it needs rebuilt. What I can tell you is that 90% of the trannies, I do go into that are used just for a simple fix... could use a freshen up.
