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.

Car jerking so that I took to reliable mechanic. He drove car and said the transmission is slipping. The mechanic said the transmission fluid smelled a little burned consistent with slipping of the transmission. The mechanic's recommendation was to wait until transmission completely failed since he thought the only option was to have transmission replaced. This 1995 mercury grand marquis has only 34,000 miles on it. I had heard recently that many of the mercury's and ford's had early transmission failure.

The transmission was replaced. The virbration/shudder continues. The going into reverse problem appears to be solved.

Torque converter went out at 20k miles and again at 54k miles. On both occasions the torque converter was replaced. On the second occasion the entire transmission went out.

Filed Mar 1, 1999 · Lights, Locks · TN

Have had the transmission worked on 3 different times. The third time they put in a new transmission. Which I had to pay for. The paint is peeling off and leaving big bare spots. I have had my right back door worked on several times because the locks wouldn't open and the windows would not roll down right now my right rear window and my left front window will not roll down!!! My car hesitates and jumps when I am going about 20-40 miles per hour, and when I hit 50-60 MPH my steering wheel starts to vibrate. My brakes squeak but we don't see nothing wrong. I have put about $3500 into this car since I bought it, and I am really sick of messing with it.
