I think I figured out my trans issue. I'll know tomorrow when I drop it back in the car. The transgo shift kit was a bit more in depth than the one for the 4t65e. Well they end up giving you all new checkballs for the valve body and they are all the same size so I ended up using them all since I ended up losing a few of mine. It turns out the size of the checkballs transgo includes in the kit are 1/4 in or (.250) while the oem one are .236. There is a note in the transgo kit that states you can use all their checkballs except the one for the bathtub. The bathtub in my valvebody is the Low/Reverse Shuttle ball. I think this is why it burned my Sun gear drum and damaged the one way outer clutch.
That would also explain why the car wouldn't creap forward when you took your foot off the brake.
Oh yeah I air checked all the clutch packs before I put the trans together, except for 3-4 which I don't own the adapter for. I replaced the EPC solenoid along with the Tcc solenoid. I could spin the sun gear drum with band applied so that checked out, they note that if you can't move it by hand you might have grind the pin a little.
Trango kit on this one recommended: drilling holes in the stator support, drilling accumulator plate, d-ring instead of accumulator teflon seals, then the usual diffferent springs,
