Transmission cooler lines: Which one is the return?


NAXJA Forum User
Over there!
I'm trying to install an inline filter on my '96 AW4. Can anyone tell me which cooler line is the pressure, and which is the return? Is the top one the pressure line?
Pressure is the front one. Return flows to the back of the tranny.

Alright, thank you.

Another question - I went to auto zone and asked for "transmission cooler" tubing. What I got was a peice of 3/8" Goodyear fuel line rated for 50 PSI. Will that be ok for transmission plumbing?
