Default 4l60e no 3rd at WOT after rebuild?

got my truck back together, ordered a kit with a good alto 3-4 clutch pack in it, now it will not shift into 3rd at WOT unless i lift a little. normal driving around town, it shifts perfectly fine. shifts 1-2 fine at WOT, havent tried going 3-4 WOT

i set the 3-4 clearance to the spec called for with the kit, has a billet servo, transgo hd2 kit, and has been tuned

thought I might add to this, I replaced the separator plate also with a transgo plate, which some of the holes are smaller than the plate I removed, I drove the truck around today, it seems to be getting worse, although once its in gear it holds like it should. and its temperamental, sometimes taking off from a light it shifts fine, others it will almost freewheel going into 3rd

also the fluid level shows a little over filled with only 8quarts in it, manual shows it should take around 11, but I didnt replace the convertor

after looking around on 3-4 clutch clearance, seems like the sheet that came with the kit on 3-4 clutch clearances may be a little off, i set them up at .040 wet, from what ive seen in my recent research, they need to be closer to .025ish, i believe i have found my issue. Which means it has to come back out, fanfuckingtastic!!

That 3-4 clutch pack is burnt, get a new one before you pull the trans.
