Tonight on the way home from work as i pulled on to the interstate my Transmission temp gauge maxed out and my tow/haul light started to blink. The handling did not change at all and there was nothing out of the ordinary. I pulled over and checked the fluid level and looked for any leaks under the truck but fluid was full and no sign of any leaks. As I was checking the fluid level the gauges went back to normal. So I got back on the interstate and it was fine for about 5 miles and the gauge and light went back to maxed out and blinking.
