I am replacing the engine in my truck. We damaged the transmission cooler lines taking it out, so I bought new ones. But we did not keep track of which port on the transmission goes to which port on the radiator.

Does it matter?

Does anyone have a picture that describes how they are supposed to route?

 

I have a 07 F150 FX2 5.4L
This kinda is what I am looking for too.
I'm installing an AUX Trans Cooler and need to know which is the RETURN line?
Everyone says install it after the Radiator.

Thanks

Rick
