I can get to 35 or 40 but havent gone any faster. I figured it was a motor mount on the right side, lucky me, there is one sitting on the bench still in OEM packaging. I put it in and go for a test drive. The bucking is still there. I am goin after the right side tranny mount next as soon as it cools off in there a little. If anyone has experienced this before or can point me in the right direction that would be great. Also a point of note, I checked the center driveshaft donut thing and it seemed fine along with all the CV's on the car. Thanks in advance!
