Which transmission cooling line?

My mechanic just gave my "new" 1995 e320 wagon the once-over and has given it a clean bill of health, but for a few minor issues.
One of them is a transmission cooling hose that originates from the radiator down on the right hand side, as you are facing the engine.
When I go to Performance Products, plug in my year and model, it gives me 4 different options for straight and curved lines of different lengths.
Does anybody know which one is right for my car?
