Funny you should suggest that. I took it out today and got it on the highway. When it started shaking I tapped the brake pedal and it would quit the shortly thereafter start again. Tap the brakes and it would quit again and so on. I figure it is the torque converter and when I hit the brakes while shaking and it stops it must be unlocking and then relocking causing the shake. The u joints all seemed tight as well. Thanks Ray.
