The NAG doesn't come with a dip stick because they don't want you checking the fluid and risk getting ANY impurities into the transmission. The NAG is very sensitive to the slightest bit of rag lint, dirt, etc. that you might get in there, which will screw up the trans operation. My guess is the OP got some lint in there during his service, which got stuck in the valve body. I'm really curious where he got the notion to rebuild the valve body. Possibly he took it to the dealer and THEY rebuilt it and now he is taking credit for the fix? He seems to have a lot of pride and I don't know that he would admit the dealer fixed his screw up?
