I have a 97 GS NT and the transmission makes this horrible noise when I start the car up for about 10 min until the car warms up and then it goes away.....I have a brand new clutch and throwout bearing in it and it still makes that noise. The flywheel is on correctly and tight......It makes a sound like rocks are in the transmission...when you push the clutch in, the noise goes away. What the hell is wrong with my transmission???????
