Default Bad vibration and spedometer bouncing when going uphill

Hello. I have a 2012 impala ls with a 3.6 liter v6 with 194000 miles on it. When i am going uphill, regardless of the size of the hill, the front end starts vibrating and jerking really bad, and the spedometer bounces back and forth by about 1mph. Has anyone else had this happen? Thanks.

Check your motor mounts and transmission mounts. If one (or more) is broken, that might cause some of what you are experiencing
