I've got a 1977 F250 Supercab

it's got the stock tranny cooler (built into the radiator) as well as an aftermarket tranny cooler

I had one of the lines blow off a while back, side of the road fix was to bypass the aftermarket tranny cooler and limp back home

I went to re-connect the cooler, and realized: I don't know what dirrection the fluid flows from and back to the tranny

this shouldn't really matter much in a closed loop
but, since I've got the factory cooler and the aftermarket
I'd like to have the fluid go thru the factory one first, then to the aftermarket Air finned cooler before going back to the tranny.

any way to tell which tranny line is the supply/return?


Thanks in advacne

The line that comes out of the forward section of the transmission is the flow to the cooler, the line that goes to the rear of the transmission is the return from the cooler.

 

perfect !!!

that's exactly the info I needed.



Thanks
