Engine vibration at 2200 rpm

[RICK LAKE]

209 cliff I am hoping for the best which is either a dampener on the front of the motor may have gone bad if it is a rubber one. If it's a ATI or fluid one I doubt this is the problem. This leaves the clutch assembly or fly wheel.
The next thing to do is make sure that the motor doesn't have a bad cylinder. pressure test and leak down. if every thing is on the money next is to pull the trans and run the motor without the clutch assembly on the back of the motor. If the vibration is gone, you have either a bad clutch assembly or there is a problem in the trans. Even through you have the trans in netural this doesn't mean there is not a problem with the inputshaft bearing or main shaft. What trans is in the car? Tremac t-5, 3550, TKO 500, Tko 600. There has been some problem with them. Do you learn any noise in the trans? If it is easy, drain the trans and see if there is any metal in the fluid or in the bottom drain plug. If none of this shows anything, your motor may be going sour. I hope not, this would be last thing to check. At this time I can't think of anything else, Cliff. Rick L. Cliff send me a P-M with a number to reach you at in the evening. I'm in NJ.
