Which side is the tranny cooler return line?
I am stumped... When I did my tranny cooler install, I used the 4x4wire DIY 4x4wire which says the passenger side one. Now I am looking at the Yotatech DIY Yotatech as well as Yotatech2 and they both state to use the driver side as the return line.
Does this make a difference? Should I take it off the passenger side and mount it to the driver side line now?

Grimpy;
I'm not sure how much difference it makes, but I have mine coming out
of the drivers side, into the TRD cooler and then back to the tranny, that
way the radiator part cools some, then the TRD cools more, then back to
the tranny. I did mine per the YotaTech write-up.

The return line is the one that connects into the lower metal tube attached to the tranny.
TRD recommends that you connect to the return line so you can cool the ATF more after it has been cooled by the radiator. If you do the reverse, the radiator will control the temp of the ATF which would negate the presence of the aux. tranny cooler.
On my Hilux Surf, the return line is the one on the driver side.
HTH.

The easy way to figure out which line is which is to:
BE CAREFUL!
Be sure the truck is nosed against something solid, and keep an eye on where your hands are reaching!
- Start with a cold engine
- Pull the skid plates off
- Start the engine, put the truck in DRIVE and nose it up against a wall
- Leave it running - and in gear! - get under the truck and grab hold of the cooler lines
- The first one to get hot is the feed, the cooler one is the return
BE CAREFUL!

Just my personal opinion.

Have a buddy in the truck is the safest thing no matter which way you do it.
