when im in 3rd and 4th gear around 3500+ rpms i can feel horrible vibrations through the shifter and the car shakes a bit? anyone have any ideas?

 

Do you have gears?

 

nope

 

mine kinda does that too, mines the flywheel i got eatin up a little when the starter started to fall out, i still have replaced either of them. anyone know how hard it is to replace the flywheel, i know the starter is a piece of cake but i'm worried about the flywheel

 

Couple thinks drive shaft
Cooling fan or clutch

 

It could be a trans mount or u-joint......Good luck

 

thanks

 

+1

 

i hate to be the dude with the bad / hard news but i got the same problem. dropped the tranny and found that the imput shaft moves and the pilot bearing just wobbles around. to fix the imput shaft i need to get a new bearing with the race. and then renistall a new pilot bearing.
hope this helps

 

gary, thats what i was thinking it might be, im buying a new trans this week anyways, so hopefully no more problems. thanks for all the advice guys.
