So I have my new tranny in, finally. But Im not sure which one of the line hookups is the output and which is the input. Trans is a TH350.


Hopefully that makes sense, Thanks

If my memory is right the lower is pressure and the top is return....

It will work either way, but I believe the top is pressure. Easier on the gravity thing for pressure to go in at top and come out of bottom. No need for it work against itself.

I don't have the answer but in industry, a cooling heat exchanger always has the supply into the bottom of the exchanger and the return out the top so it is always liquid full to achieve the most heat transfer when in use. Of course in an auto the radiator is just the opposite so who knows.

This is correct. On the tranny the top fitting connection is the return.
