On the above date while on a local interstate my car failed to respond to acceleration. Instead the engine revved and then began clunking and making horrible noises. I drifted to the side of the road as I had no control of the motor. I had the car towed to my dealership. They said the was a "catasrtophic failure" of my transmission. I had had no warning of any kind. I have always had all my warranty work done in a timely fashion including all transmission work. My dealer estimated a repair job costing $4,400. I got 2 other estimates including one from trusted car mechanic who told me he recommended a jasper transmission (total rebuild) and it included a "work-around" for my make, model, and year car's transmission "problem".
