Vibrating car

[mischf]

When I go above 80 in my auto V6 my car starts to vibrate. Its not a steering/alignment problem it's coming from the tranny or driveshaft somewhere. You can notice the vibrations a lot more in the white D, if you put it in the blue D it is a lot better due to lower RPM. Is it possible this is just caused by a transmission mount? Or is something likely to be bent somewhere like the driveshaft? Just wondering what some common causes of this are thanks.

maybe try checking ure tranny cos i shattered the bolt mounts on my drive plate and she was shaking all the insides of my car but i also destroyed the inside of my tranny but i think most the shaking was from the drive plate

after you have checked that go over ALL the drive train mount bolts from engine mounts to diff mounts.some of them can work loose (like my auto mount bolts did)then check for a miss fire..
DONT forget to check your torque converter bolts
