1: My cruise control is jerky (works, but feels like pressing gas/brake back and forth)
2: My speedometer fluctuates. The slower i go, the more it fluctuates. At around 30-40 it will drop to 0 and move between. At 70 it works just fine.

I just tested and I have about 15lbs vacuum. I dont know what to think of this is that low or high?

All of these issues started around the same time, right around the time my transmission mount tore. It is still torn.

I figure all of these issues are related since they all started at the same time. What would that be though?

Any help is greatly appreciated!
