I'm the proud owner of a 2008 GT500. I've got some clutch chatter. My car has a Spec clutch in it. The Ford dealership couldn't remove the transmission, stating that the input shaft was stuck/seized in friction disc of clutch. After talking to the service manager, she stated the tech only had a few millimeters of space between bell housing and transmission. What are some old school tricks that will help free things up? I have plans up replacing the clutch with a better quality replacement. I'm not too worried about the existing clutch, but I don't want to end up on the side of the road. tyia
