Noises During Shifting problems of the 2006 Acura TL

I had the most harrowing experience while driving home last Saturday, Nov. 27, around 1:15am, at constant speed of 60 mpg when suddenly while stepping on the accelerator pedal I felt slipping of the gears, then the car's acceleration quickly dropping as I frantically tried to regain control and barely managing to steer the car onto the shoulder where it stopped to move completely. I realized then that the car wouldn't move in any gear I shifted it to, which is indicates to me of a failure relating to transmission, if not a failure in the automatic transmission itself that caused this very dangerous incident to happen. I had to call aaa to have the car towed to my driveway where it still is as of this writing. I had no prior knowledge of any transmission problem with this car nor should suspect of such since I've been current with all scheduled maintenance services and kept it in good condition at all times. On Nov. 24, three days prior to the incident, I brought the car to Acura to make sure I had the 'power-steering hose recall' service done since days prior I've been hearing unusual grinding noise around steering wheel, amplified upon turning even slightly the steering wheel on either direction, usually when the car is started the first time. I thought the noise I hearing might be related to this 'recall' service. However, according to Acura that service had been done on my car last February 2008, but it would cost me $110 for them to diagnose the problem for which I opted them not to since I didn't have the funds. I believe an incident such as I have experience wherein a moving vehicle would suddenly lose power and become immobilized within matter of seconds poses a very serious 'safety risk' to our highways that should warrant prompt investigation and resolution to its cause to ensure responsibility of our continued safety.
