it appears that you have malfunctioning gages. this is most probably a malfunctioning sensor at the transmission speed detection unit (SDU) take your automobile to your local shop and get a qualified technician to diagnose your malfunctioning SDU

That would make the lights on the gages and warning lights cut in and out along with eat and gas needle?
