The car make a loud crackle sound when I make a left turn, and also my transmission starting acting up. I took it back to the dealership where I purchase it from and they told me nothing was wrong, and I had the extended warranty, but I took it upon myself and took it to a transmission shop and I was then told that I need a new transmission. So the dealer lied to me and now my warranty ran out and they won't fixed it. What can I do. I also see alot of recall for my car that no one never sent me info about.

On 08/18/2008 my mother took her vehicle to sunnyvale Lincoln Mercury dealership  732-7000[she purchased the vehicle there] because she was having problems getting the transmission to go in gear using the gear shift handle on the steering colomn. The dealership [invoice 24804, gabriel medina] said the transmission needed to be replaced. The vehicle drove o. K. It was just hard to go from park to drive. My mother is 86 years old and lives by her self. I feel strongly that she was taken for a ride and cheated out of $2,611. 93. She was never told as to why the transmission needed to be replaced, she drives a 2000 Mercury Grand Marquis with 17,352 miles on it. All oil changes and service work was done at the dealership from day one. Now the transmission is missing. Her warranty coverage for the transmission is her receipt from the dealership. There was never a problem with the shifting of the transmission once she got the gear shift handle to go to drive. So, if there is a problem with the linkage from the steering column to the transmission, why did the transmission have to be replaced?.
