i have an automatic 92. i replaced the dog bone motor mount on mine. improved the shake alot. u notice it more when u back up. just open the hood and look straight down in front of u..right in front. ive not replaced any of the other 3. these r 4 cyclinder engines there will be some vibration at idle.
what problems shifting? u moving the gear shift thru the gears or the tranny shifting itself while driving?
