List, When I first start my car and let off the clutch in first gear, I get a rumble from the transmission/cluctch area. Could this be related to the throw out bearing? It seems as if the gear and clutch "don't catch, then catch" repeatedly. It lessens as I get going. When fully warmed up, it smoothes out...Or, do I have a more serious problem, like the transmission? Joshua Schwartz Trumbull, CT 001292
