My transmission seems to shift fine but at random it shakes. It’s like you are driving over rumble strips. What might be the problem?


#2

Out of balance tires, out of balance driveshaft, failing U-joints. If this truck has a 2 piece driveshaft it could be the center bearing based on the very little you told us.
