which is the return line?
I have a 2003 edpedition with 5.4 and the 4R70w trans
Want to pump out all the fluid since there isn't a drain bolt on the torque converter.
Was thinking I could put a long hose on the end of the return line at the tranny, pump the fluid out till it gurggles, then drop the pan, and change the filter.
Anyone know which line on the side of the tranny is the return line?
Thank you

its the top one on mine. yours is probably the same or similar, mine 4r70w though. i did the flush on mine, using the return line to catch old fluid and adding new as the old pumped out at the same rate. doesnt have to be perfect, but when you done, just make sure its at the correct level.
