Automatic Transmission problems of the 2006 Saturn VUE

I am the owner of a 2006, 6 cylinder Saturn Vue. Jan 2011 I took my car to an authorized Saturn dealer. Lannan Chevrolet in lowell, MA because the coolant light was on. They did a diagnostic and said the collant had to be flushed, I got this done at the dealership. August 11, 2011 I was coming out of boston and at a few red lights the engine didn't seem to want to go. As I was exiting the tunnel going onto the zacome bridge my car just lost all power and died in the high speed lane, I was traveling about 60 miles per hour. I had to put on my hazzard lights and call 911. I was told to stay in my car and keep the lights on. People were beeping and I was scared I would die from being hit. The police officer arrived and told me I had to move the car from the speed lane to the right shoulder of the road. The car wouldn't move. He kept telling me shutit off and start it again, shut it off and start it again, after 5 attempts I was able to move the car to the right lane before it finally died. They could nto get the car on the flatbed because the ignition would nto turn. After several attempts the ignition turned and the car was towed to south boston stae police barracks. From there I had to get a tow to someplace locally as this was an emergency tow. I finally ahd the car towed to lannan Chevrolet in lowell where I was toldthe following day the transmission was gone. I called staurn customer service and filed a claim. The car has 53,076 miles on it and the transmission went without warning. The distrcit manager of lannan Chevrolet said "I must have abused the car and reved it" I was told she told the service manager daryl that she didn't want to hear anything else about my vehicle. Saturn customer service told me the claim would be escallaed to the "next level" and they never heard of any transmission problems. Upon looking up the vehicle on the web I have found thousands of complaints form Saturn owners concerning the transmission and a class action law suit. Gm???????.

Carrier bearing replaced.

Vehicle engine revs between 30-40 mph and surging is felt while driving. Vehicle also sluggish at times upon acceleration. Car was in shop first time and they ignored my concern. The second time (now) car has been in the dealer service department for 30 days and they cannot diagnose problem. They are contacting gm technical assistance and will have an engineer examine the car now.

My wife's 2006 Saturn Vue has a transmission defect that is not in the newer models. You can shift into gear without your foot on brake while the key is in acc. I told Saturn and then said gm said that is the way it is designed to work. They did change it on the new models and every other car you must put your foot on before shifting. I had it back for it and they said nothing could be done. Can you help me with this.
