Hello everyone, so My car is making a weird vibration from accelerating from slow speeds to high, A few months ago I had a RXT put in my Kilpatrick Engine and Transmission in Waukesha Wi. They have a great reputation and do good work. Fastforward a few months later I have my car at Firestone(only place I could get into to change a serpentine belt) and when they drove it they told me it was the clutch? The clutch is not slipping and im getting full boost, I think its the driveshaft or a bad U joint. Any idea on what this could be?
