Put a Tremec 3550 in my FFR this past weekend - boy, talk about a tight squeeze - and now I have a vibration problem. It starts arouns 2100 rpm and lasts until about 3200 rpm. Seems to be worse on decel than accel. Shakes the whole damn car. Really pissing me off. Also put in a new Ford Motorsport clutch & pressure plate and had the flywheel turned. The vibration is felt with the clutch in or out, in gear or in neutral. What have I done wrong???
Any ideas will be appreciated. I really do not want to take that trans back out, but I think that it has to have something to do with the clutch and/or flywheel.
