I was driving in my neighborhood today and put it in neutral as I was rolling down a hill. I was going about 25mph a blipped the gas. When I did it my speedo dropped to 0 for a second and a light that said (at oil temp) flashed. I did that about three more times successfully. It won't do it at any other speed. I tried again later a 25mph and got it to do it again. Has this happened to anyone else?
