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.
 
I believe that the upper hole is the outlet on the AOD and the front is the outlet for the C4. I'm in the middle of swapping an AOD for a C4 and have just ordered the fittings and line from Summit to plumb the cooler. I found it interesting that the cooler literature (Hayen) said to put the cooler in front of the radiator and run the ATF from trans to rad to cooler to trans. The radiator installation manual (BeCool) says NOT to put the cooler in front for the radiator and to run the ATF from trans to cooler to rad to trans. I'm going with the Hayden recommendation.

Good luck,
Kent

I'm using a 27,000lb gvw cooler and bypassing the radiator entirely.
 
Hooked them up...
