I need some help on the hot fluid out of the trans & the cooler fluid back into the trans. I have the 4 port cooler. Radiator in & out. Transmission in & out.
I have tried to feel both transmission lines to see which is cooler but they are both so hot i cant tell. On other cars there is more of a temp difference.
The 2 rusty headed bolts are the feed lines on the trans. If anyone can tell me which one is the return line of the cool fluid i would be grateful.
I know i could unhook 1 at a time & see which one spits out fluid but i would rather not.

I was wrong. This device warms the fluid so that would mean i need the side with the hot fluid that goes back into the trans.

So i had to unhook the lines. The bolt on the right is the output line. You should install a trans cooler on this line
& it will help the trans. shift & work better.
