I have a 94 Concours,106,363mi, awesome car, and when I am going about 40-45-50, holding my speed, the car chakes. If I am accellerating or slowing down it doesn't shake. It has done this since I have bought the car. I had my transmission rebuilt and it still does the same thing afterwards. The transmissoin guys told me it is running and anything they do from here would be extra.
I keep premiun gas in the car and it doesn't feel like it is trying to shift gears or anything, it feels like the wheels are out of allignment/balanced. Everything else is ok. Fluid is ok..
What do you all think?
