Oil flow direction for HDJ81 AT

[BCR4619]

By looking at the Toyota EPC it's showing that the ATF flows into the left side of the rad then exits via the right side and into a loop before returning to the oil pan. (if you are looking into the engine bay)

I am in the process of hooking up a tru-cool before the radiator oil cooler.

Cheers!

Did you mean like this? Anyway, I don't know if I can still trace mine and check if it's installed properly... the coolier is already in place and I don't know if the mechanic installed it correctly.. any tips?

It's been too long since I messed with this, I think if you get under the truck and track the upper hardline from the trans, that's your feed line, and the lower is the return line.
