Posted:9/18/2013 13:00 I have a 1999 Mercury Grand Marquis LS. 91k It has air ride and performance suspension. There is a sound like you are running over rumble strips every now and then. Reading on forums it sounds like it is a transmission issue. I am looking into having the transmission fluids changed since I do not know if it has ever been changed since I just purchased it. The question is should I have it flushed or should the pan be dropped and the torque converter drained also?
