Transmission Noise problems of the 2003 Mitsubishi Eclipse

After my purchase of a 2003 Mitsubishi Eclipse gts, at ira Nissan in tewksbury mass. I took the car to a mechanic. I was told that there were numerous problems with it including a transmission problem. I possessed the car for a day and a half and it has been in the shop now ever since. It has been about twelve days now. I have been going back and fourth between ira and a Mitsubishi dealer which they are affiliated with. They told me that the noise in the front of the car is where the transmission is. The noise which sounds like rocks flying around in the front. The dealer said this noise is normal. The ira general manager also told me that it is normal for my car to go up to the h on the hot and cold gauge. He said his does it all the time. Ira said that this issue was fixed. I have not seen nor driven the car yet since I brought it back so I do not know what is fixed and what is not fixed. I called the Mitsubishi motors headquarters in texas, and gave then my VIN number and they said there are absolutely no recall on the transmission of this specific car, nor should this noise be occurring. I also went on safercar. Gov and they too said the only recall on this car is about lights. I also called ira 3 days ago and they told me that they lost my title and I can't register my car either. Now I need some information on my options and where to go from here.

The caller said that his vehicle is making a noise. When accelerating the vehicle changes gears hard and he did not know if it was the transmission or the motor mounts. The problem occurs intermittently while driving between 35 to 40 mph. Right after having the transmission fluid changed. He had the motor mounts changed 8 times. The dealer did not remove the battery to get to the motor mount, but they said that they did. An independent mechanic told the contact that the problem might be the transmission. The manufacturer has not been contacted yet.
