I have been through this BS with the radical downshift into first gear upon a slow rolling stop. Been to the Dealer twice and talked to the Service Manager a number of times. Also a discussion with Ford, but the person knew less than nothing. The story I am getting is that this transmission is a new design, not the old accumulator type transmission. They claim it is a much improved and beefier unit that will last longer. The shift characteristics are harsh initially until the computer learns the correct adjustments. Also needs a break in period. Ford claims the shift performance is acceptable given the design improvements. My bitch is the fact that they don't tell you about the tranny until after you buy the car and then have to deal with service department to get answers. I now have 1700 miles and the tranny is getting better. The only service that can be done is make sure you have the newest computer codes flashed into the unit. Mine came from the factory with the latest codes, so basically all they could do was re-flash the same codes. My truck was delivered early February 2007. Think Ford is in for a surprise, as there are many complaints about this transmission's initial performance. I have started a complete and detailed log of all the discussions I have had with the Dealership and Ford on this problem. I hope I will not need it in the future, but I am skeptical about this tranny.
