Flashing indicated gear light on dashboard
From time to time while driving my 2007 Mazda 5 Grand Touring (auto) the light on the dash showing what gear I'm in will flash or occasionally go out only to reappear after a few seconds.
This usually happens in 4th gear. That alone would not necessarily be a concern to me but sometime when this happens the car will momentarily shift into 3rd gear only to shift back when the light reappears. A bit shocking when you're at highway speed. I have no warning lights on the dash and the trans shifts normally and the trans fluid is new and topped up. Any ideas?
