Does anyone know which line is inbound and which is outbound from an AOD or a C4? Usually it does not matter, but I am connecting an aluminum block inline with one of my lines so I can get a temperature probe in there for a gauge. I'd prefer to have it on the line coming OUT of the tranny and on the way to the cooler. The two lines are right next to each other so I guess I could swap them later and figure out which is the right one since it will be considerably hotter. But If I was able to get the right one right off the bat that would be cool.
