Sounds like it could be the transaxle mount, but I would consider inspecting the torque strut as well. I have included diagrams and instructions to replace all of the mounts if necessary.

WHERE IS THE STRUT YOU MENTIONED THANKS
Expert:  Your Auto Inspector replied 6 years ago.
The torque strut is in the upper left box of the first diagram. It bolts to the bracket above the radiator.
Customer: replied 6 years ago.
there is no torque strut on car!? Thanks, Wayne
Expert:  Your Auto Inspector replied 6 years ago.
Does it not have a front top mount (torque strut is commonly referred to as a dogbone because of its shape)? According to the diagram it bolt above the center of the radiator and to your engine.
Customer: replied 6 years ago.
no it is not there . there is nothing between the motor and the radiator.
Expert:  Your Auto Inspector replied 6 years ago.
I would then assume that the front lower engine mount serves as a torque dampener.
