transmission over temp light comes on

Ntp

09 Dodge Charger what make the teamputer light come on a red light but the car wasn’t running hot

I am also having the same issue. I have had this same issue for the past 4 years. I drive several hours at highway speeds. The Transmission Temperature light comes on. If I go slower the light does not come on & I can continue to drive the car. I can drive about 5 miles before the car goes into "limp mode". I was just informed I need to have the Radiator replaced along with 2 thermostats, and the Coolant Manifold seal. I have the Lifetime Warranty but because the service was not performed I will have to pay out-of- pocket for this = $1,575.00 + tax. REALLY. I agree this seems like an ongoing issue that A LOT of people are having.
