1985 700r4 transmission flush question...
which line coming off the radiator is the transmission fluid return line? i'm thinking the return line is the bottom or lower line. i'm going to do a complete flush (never done it on this car), and want to double check . also, i'm considering on royal purple synthetic - pros, cons, comments, etc., car has 103K miles - no significant transmission problems. - TIA
