It has been on for two days and i have an appointment to have it looked at tomorrow. The light is flashing off and on. When I accelerate, there is a strong vibration throughout the Jeep. I am assuming it is a transmission problem as when I brake the vibration stops. A few months ago I had an inspection and the mechanic told me my Trans. Filter was cracked and I needed a flush. The Next day I got one. Is there any chance the filter is still broken and that could cause the strong vibration? If not, any ideas what it could be? thanks.
