Ok guys I got an o6 mustang gt 4.6 3v 5 speed manual. I replaced clutch drained all brake fluid put back new. When cold start car I can ease off clutch and it will roll out into first gear, after running temp up on Mt hour drive if I stop and try to ease out of it it rattles and shakes like it's gonna stall out but if I get it up to 1500 -2k no noise. Only happens on take off. The car has 127k miles checked flywheel didn't see anything noticeable why under it any ideas would be greatly appreciated.
