Well, after a 2nd transmission was installed thinking the first was bad, my shop realized they misdiagnosed what was wrong with the new transmission. After replacing my original one due to bad synchros, there was a rattle. We were given a new transmission and the rattle was still there. The shop is going to cover the labor for the mistake. Now, has anyone used one of these Clutch Masters single mass flywheel? I'm asking because I can get it cheaper than the factory dual mass and save a few lbs. If you've used it, how bad are the vibrations etc while driving normal, with the a/c on, does it need to be revved a little more to get the car rolling, I mean anything anyone knows would be appreciated. Thank you.
