Calm down everyone!
First off, hold off on any aftermarket parts when you are planning on going in for Warranty work unless your dealer has Ok'd it in writting. You don't want them to screw you and blame any problems on the shifter.
2nd, the conversation that I had with the Ford corporate guy 3+ weeks ago said that this "mini-grind" is considered "no effect on performance or durability" it is acceptable.....it is NORMAL. Maybe they came up with a fix over the holiday???
3rd, there will never be a "Recall" This will be a silent recall or TSB. Part of the if you "If you don't ask, we won't tell" approach Ford has. A Recall is sent to every single owner for major safetly things like airbags, brakes, seatbelts, steering..... If there is a fix, only people who complain will get the fix.
