Shifter shake problem

[ScreaminSER96@cs.com]

Hey everyone-  I noticed a shake in my shifter going around right hand turns
when I am on the gas moderately to heavily.  I was wondering if this is a
sign of a broken motor mount.  The vehicle is a 96 b14 and has 73000 miles on
it.  I recently installed GC/AGX but this problem has not been there until
after i dragged the car at maple grove over this past weekend.  What are some
tell-tale signs of broken MM?
