Default 88 subaru GL auto transmission cooler lines location

changed water pump the other day and went to put the radiator back. For
an automatic tranny equiped cars, the tranny fluid is cooled by running
the tranny lines into the radiator. I got the lines mixed up and do not
know where they are supposed to go back in. From the tranny, there is
one line coming from the front left side and another coming from the
rear left side of the tranny. Both these lines are run into to the
left side of the radiator, one at the bottom and the other at the top.

I need to know which line goes into which part of the radiator.

I got 88 GL 1.8L FI EA82 non-turbo 4-door with an automatic. The Haynes
manuel I have does not seem to have a diagram showing the tranny cooler
lines going into the radiator. I forgot to lable them when I took them
out, creating the problem I have right now.

any help is appreciated

PLEASE get a second opinion on this, but if I recall correctly on my 92 loyale project car, the fluid came FROM the transmission torque converter area, into the TOP of the radiator, out the bottom of the radiator, then back to a long S shaped metal tube that returned to the ATF pan.

So... trace the hose back to the tranny... if its the torque converter one it goes on top, if it goes to the tube (to oil pan) it goes on the bottom... like I said please get a second opinion, its been afew months since I sold this car.

Technically, or not, it doesn't Freakin matter!!
All it is is a coil type cooler that the fluid flows through in the tank of the Radiator.
Anyway, you should only be able to re-connect where they came from as the hoses from memory are different lengths??
Doesn't matter anyway!!!

The bottom fitting on the rad is the inlet, top is outlet(I thought this would be the other way around...gravity). But in the FSM there is nothing showing what line is what from the tranny. The shorter hose, I assume, is for the inlet (bottom). If they werent disconnected from the tranny it should be easy to see which one is long and short.
