2005 F150 with 4R75W transmission. I disconnected both lines at the aux trans cooler, and placed both lines in milk jugs. When I started the engine, I was only expecting fluid to come out of the return line. But to my surprise, fluid came out of both lines, at about the same rate.
Just wondering... doesn't tranny fluid follow a certain path, out of the tranny, into the radiator, into the aux cooler, then back into the tranny? Then why would fluid of come out of the the "to" and "from" lines?
All in all, it was successful though. I flushed a total of about 20 quarts of fluid through it. Max capacity is 13.9 quarts, so what I did was more than enough.
