Does anyone know which Trans line is the exit and return from Cooler ?

Thanks,

The ones connected to the cooler.

 

When truck is cold start it & run it for 30 sec.Cut it off &
feel lines one will be hot so dont hold on to it,that is the
one comeing out of trans.Good luck

I believe the line most forward of the tranny is the output. There is also a cooler bypass line on the transmission which only opens when the temp becomes high?

Factory tech we need you!?

 

You might have to crawl under to see it but, the lower line is the return to the trans.

 

The line at the rear of the transmission is the "in" side, the rear lube port, the one at the front is the converter out or the "out" port to the cooler. My admittiedly crude way of remembering it is the E4 takes it in the ***.
Hope this helps.
