Transmission Fluid Leaking problems of the 2003 Chrysler Sebring

After picking up vehicle from dealer and reporting "slipping" on the transmission, the dealer told me the transmission was starting to break up. A new one would cost $7,000, and a refurbished one would be $5,500, and there was a waiting list. I decided to drive it home an explore other avenues. The vehicle lasted maybe five miles and it died on the freeway. The engine light came on, the engine started smoking, and the engine just died. I lifted the hood and the engine was smoking as the transmission had broken and it had been leaking its fluid on the freeway. I called a tow truck to tow it home. An independent transmission repair shop will charge me $1,800 to rebuilt it. I have no choice.
