I have a 4L60 behind my 5.3 swap into my 72 Jimmy. I have searched for hours and can't find which line goes where?

Top of transmission to top of radiator? Bottom of transmission to bottom of radiator or am I backwards?


Thanks
Mark

shouldn't matter much its flowing through the same location just different direction its using the coolant to keep cool so it will do its job im sure after i mixed mine up many times now i just use a separate cooler but "i think the bottom is feed and top is return"

It makes no difference. Both are pressurized and the rad side is just a coil submerged in coolant

The lower is to the cooler, upper is the return. I ran the factory cooler in the rad and a aftermarket cooler in my truck to keep things in check. As to where they go on the rad, I'm with everyone else. It shouldn't matter.
