Transmission Gear Slipping problems of the 2009 Ford Edge

The 2009 Ford Edge I own has been experiencing slipping and surges in acceleration while trying to maintain a constant speed at a 45-55 mph range. While decelerating the transmission slips and revs up and down causing the car to jerk forward and/or suddenly slow or stop. There are numerous TSB for the 2009 Ford Edge transmission ( TSB 10-21-2, 10-17-4, 10-9-9, 13-5-27. However, the TSB's state that they only cover 2009 - 2011 models built 3/13/2009 - 6/30/2010. The TSB's explicitly indicate the 6f50 and 6f55 transmission. My 2009 Ford Edge has a 6f50 transmission that happens to be built on 10/24/2008 and therefore, Ford is limiting its liability because a date range was placed on the TSB. Yet, my car exudes the same performance and flaws outlined in the numerous TSB's. As well, there are several other complaints on NHTSA related to the 2009 Ford that Ford is refusing to repair if it falls outside of the date range. This is a very shallow way of limiting liability and a lack of responsibility and ethics on Fords part, imo. I would like to point out that TSB 10-9-9 covered 2009 Ford Edge built between 12/11/2009 and 4/15/2010 and then TSB 10-21-2 extends the date range to 3/13/2009 through 6/30/2010. An investigation should consider if the 6f55 and 6f50 transmissions in general should be recalled. Given that my car meets all criteria other than a date for a well known defect, it appears Ford has found a great way to circumvent liability on poor designs and manufacturing and place the financial burden and safety risk on the consumer. I am requesting that an investigation be initiated to expand the tsbs related to the 2009 Ford Edge to a recall on the transmissions in question, 6f50 and 6f55. Currently, Fords only response is to request that I pay the repairs and keep the receipt in case the TSB expands to cover my manufacturing date. Complaining here is my resolution:).
