I was just wondering on a 4l80 which cooling line was the "out to the cooler" and which line was the "return from the cooler" fitting? My 80 is set up with the cooling fittings in the front and rear location on the side of the tranny, not top and bottom like the 60.

TIA

 

Ttt...

 

The front line is pressure.Rear is return.

 

Thanks for the help Vince!!

 

Doesnt really matter
