Re: Transmission lines 4L60e to stock 71 rad cooler

Bringing this back to the top. I have the correct AN adaptors at the transmission (4L60e) now which AN fittings do I need to thread into my radiator? Specs of the EC369 state that the trans cooler fittings are 1/2" 20 STRAIGHT THREAD G1/4. Also which is in and out of the radiator? Top I would assume is the inlet...thanks all.

Inlet is the bottom, you want to push fluid up so it fills the void, if you go in the top it will just fall through and might not fill the cooler.

Incorrect.....At the Radiator....The top is the Inlet & the bottom is the Outlet.
