I am trying to figure out a vibration.... hmmmm.... Is it possible that a vibration could be caused by a slightly slippin clutch??? I dont really think it is slipping wouldnt it slip in 4th and 5th more than the lower gears? I accelerate hard in first gear and get a vibration (from the drive line somewhere maybe). Today i took off from a stand still on a steep hill and got a lot of "chatter" I have heard this may be from a flywheel that needs to be resurfaced.. may this be the area i look to solve the shake i cant shake??
