Has anyone experienced a low speed shutter...at roughly 20 - 23mph or 1000
- 1200rpm if I get off of the gas to go around a turning car or something
and then lightly get back on the gas the car briefly shakes/shutters -
almost like it's in too high of a gear or something. Then it will
gradually pick up speed after the shutter. It's almost like starting in
5th gear from a stop in a manual car.

Thoughts?
