i have a 92 325i 5spd... the problem i am having is at approximatley 23-25 mph the the car shakes for a few seconds like something is off balance, you can feel the wobble the strongest directly under the center arm rest atop the transmisson. thats the only time it does it runs drives and shifts perfect any other time.it has jut started doing this within the last week..i dont know if this would be related but i have noticed that SOMETIMES when you push the clutch in and put the car in gear you can feel it engage or move a little..thanks for reading and any imput you may have.
