Title: Help verifying which fitting is return line (4L80E)
Post by: scorpion on September 22, 2012, 08:56:42 pm

Found this on the B&M website

I've seen older 4L80 fittings and the rear one is way at the tail of the tranny unlike mine.  I'm guessing mine is the "above/below" one so the top/rear one is the return that should come from the top of the radiator (the top is out right)?  A confirmation from someone that knows would be great.

Thanks!

Yours is the early style.  The upper one (at the left of the pic) is the "upper" one.

Thanks, it seemed fairly obvious but wanted to be sure.
