I have noticed heavy vibration when in "D" when i received the car earlier this year... i changed the transmission oil since when i looked, the fluid level was very low and some of the vibration and pulling between shifts softened up alittle. I was planning on changing the front engine mount since when i poked it, it cracked even more... lol.
Does anyone know how many mounts there are holding the engine and transmission to the car?
I will post back with results after changing the mounts.
Thanks for all the feedback!
