727 trans rebuild

Well, the clutch packs are good to go, but I am having a big problem with my end-play specs. When I look at the book it says to have a plastic thrust washer in between the pump and front clutch pack, My thinking is that it should be in between the input shaft and the front clutch pack. The endplay is WAY too much like .150". I think where I really messed up is that I did not check the end-play before I took it apart. Any ideas?
