Transmission Warning Light
I left home pulling a 10K trailer and after 15 miles the transmission temp guage pegged out as "Cold" and the tow light starting blinking. Transmission didn't seem to have any problems. Any ideas what's going on? Do I need a fluid change? This truck has 190k miles. Thanks

My money is on the Transmission Fluid Temperature Sensor....... I had the same issue about a year ago.
It's a pretty easy fix if you've got about an hour. You have to drop the pan to replace the sensor.

My quess is a little more love then that is needed. When my truck at 42,000 mile started flashing the tow light I got a new tranny. Check the fluid level and can you check codes?
