c6 transmission
This is a 55 f100. c6 9" rear 302 engine
Thanks
With that combo you shouldn't have engine vibes causing issues. Is your drive line lined up correctly? U-joints lined up right? DS balanced? Correct flex plate in the engine?

You fail to mention this amount of slop in this post. Hanging a weight on your trans isn't going to fix this problem.
