My 2019 ST has developed an almost sub woofer thump since ford reprogramed the transmission a month ago. It was just once in a while to began with, but now I here it more often, and rarely am able to feel it. Happens mostly in reverse but sometimes when leaving a stop sign. Super deep thump, like a bawling ball hitting the back of a padded trunk. I am sure it won't make a sound if I take the crazy problem to ford. Thats why I am posting to see if anyone else is hearing this thump. I would swear it the sub woofer, in the back. Larry
