Transmission slipping (like driving over rumble strips)
My transmission is slipping really really bad. Every 5-10 seconds it feels like your driving over rumble strips. the whole car shakes and slows down a little bit. I am not sure what i need to do to fix it. I checked the transmission fluid and it does look black or have any particles in it. It is a light brown color. I have read that some people recommend doing a transmission flush or to get a new MLPS sensor or something like that. What should i do?
