Automatic Transmission problems of the 2007 Ford Fusion

Took 2007 Ford Fusion in under warranty three times stating it was shifting hard, rpms were high and that felt there was a problem with the transmission. After being dismissed each time the warranty lapsed and the car lost the transmission in the middle of the freeway. As this was a reported problem on my service records, tried to get Ford to cover their product and show customer loyalty with no avail. Lucky to be able to get out of the middle of the freeway when the car had no acceleration or power behind it. Started taking vehicle in June 2009, then Dec 2009 and lastly in Feb 2010. After being dismissed 3 times I continued normal driving conditions since the car was deemed to be "normal" now it does not have 2nd or 4th gear.

While traveling from canyon to norris in yellowstone national park, I attempted to control the speed of the vehicle manually while climbing a steep hill, but found it impossible. The desired speed was 45, which is the maximum speed in yellowstone. The throttle has a delay of about one second, so it is continually 1 second behind the commands of the driver. The result is that the vehicle always overshoots the speed because the driver first expects a response from the vehicle, but gets none and continues to push the accelerator pedal farther down. When the vehicle reaches the desired speed, the driver lets up on the accelerator, but the vehicle continues to accelerate according to the command 1 second ago. The driver then continues to let up on the pedal because the vehicle has not yet responded to the command to reduce rpm. The transmission shifts up when the driver lets off the accelerator. The vehicle then undershoots the desired speed and the driver pushes the accelerator down again. The vehicle again delays its response and the transmission adds an additional delay of about 2 seconds. The next overshoot is worse. This oscillation continues until the driver gets frustrated and sets the speed control. The speed control still fails to maintain speed when the grade changes rapidly, but the slow down is much less and it recovers in a couple seconds and maintains speed the rest of the way up the hill. The driver then has to ride the brakes on the way down the other side of the hill in order to maintain speed, which releases the speed control. The driver then has to set the speed control when the vehicle reaches the level again. If the driver lets the vehicle continue to accelerate down the hill, the transmission will eventually downshift at about 48 miles per hour, but continues to slowly accelerate. Continually trying to correct for the lack of control of speed results in an excessive distraction and continually takes the eyes of the driver off the road.

I bought my 2007 Fusion at end of March. Since then I have noticed on a daily basis that when I am at a complete stop and try to start the accelerator is very touchy. I peel out almost 75 percent of the time. The gas pedal shouldn't be that hesitant or touchy. I am afraid to change my own oil which I have done all my life. I am afraid of driving right off the ramps. I am very afraid of merging into traffic at stop signs. Especially this next year for the winter season. I had a few instances at the end of the snow season I couldn't even get going in my own driveway because of the over power. I would just spin out with the instant over acceleration. Also at stop signs that were snow covered. (that has never happened with any other vehicles I have owned. ) also the acceleration of trying to pass someone there is a major hesitation to switching from overdrive to drive and back again.
