Toyota Repair: transmission/motor mounts on 96 Corolla, vibration problem, toyota corolla

Question
I would like to know how to replace the transmission mounts/motor mounts on a 1996 Toyota Corolla.  Are the transmission mount and motor mounts the same thing or two different things?
Car has a vibration that is worse when you put it in gear.  Is this something we can replace ourselves or does a mechanic need to do it?

Answer
The motor mounts are all different and not that easy to replace, requiring some tools and a floor jack and jack stands, unless the car has been in an accident and not run over something in the road then replacing only the front mount, on the inner right front fender/front of the engine may solve the vibration problem so try doing that first.
