I need to change my front transmission mount (driver's side) and i'm thinking of doing it myself. Anyone ever changed this? if so, how hard is it?

 

its not too hard, just support the engine and tranny with seperate jacks. Follow the directions in the FSM or Haynes. Be careful of the clutch line/brake lines.
Good luck.

 

Actually, since it's one of the side mounts you dont need to support the engine/tranny. I have unbolted that mount in 15 minutes with no support and had no problem remounting it. It's only purpose is to absorb the engines twist during jerkiness acceleration/shifting
