problem details
this morning on my way to work my cuise stopped holding speed. I turned it off and tried angain and it would not work. I am getting power to the switch and the dash show cruise on, but it will not hold the speed. I also thought the trans might have been slipping, but as soon as I released the cuise and pressed on the gas it was fine. Thanks Robert
