trans. seems to be slipping when in 4th and lock up with edge comp on any level higher than 3. With comp off it shifts fine, fluid ok, filter ok. I think its the stock trans. What do you think?? thx.:bang

You have in your post that you think its stock trans, but in your sig it says built trans... I dont follow, is your trans built or not?
