Tranny cooler lines

[jimbomac1961]

Hello guys. I have a 2009 1.8L auto trans. Corolla S. Can anyone tell me which tranny cooling line is the return line?
I'm going to install a trans cooler. I've followed the instructions that came with the cooler to identify the return line. But I still can't tell. My gut says its the top line, just like a radiator.
Can anyone verify?
Thanks,
Jim

subscribed. I have to install a trans cooler on mine as well. Same generation... (same drivetrain anyway)

I would guess your gut is correct, but confirmation never hurts.
