Shifting issue

[clutchpack]

Ok so I repleced my 5r55 with a used one and Im having hangup problems. It wont upshift unless I get off the gas from 1-2 and 2-3. Not slipping but acting like I have it manually gear. I can roll all the way up in 2nd and it doesnt want to shift, let off the gas and it shifts fine. EPC solonoid? Separator/vlave kit?

sounds like the valve body hanging up how many miles on the used tranny?

50k on the used tranny. Its been doing the slip thing as well. Guessing im going to anve to do the valve kit and the epc solonoid.
