I have a 2014 F150 4wd 5.0 L with elec 6 speed automatic and factory towing package. It has 48000 miles. While driving on 4 lane, light traffic outside temp ~70 degrees a warning light came on saying something to the effect "Warning excessive engine temperature. Press OK." A quick glance at gages showed the engine temperature gage bottomed out on cold side, Transmission temp gage in normal range. Pressed the ok button, stopped and checked the coolant level as ok upper and lower radiator hoses were warm but not too hot to hold. Started driving again and the engine seemed to be struggling temp gage still not working. After 4 or 5 miles noticed the AC quit working the and the over temperature light came on for the engine. Stopped again and checked upper and lower hoses same as before radiator was relatively cool to touch. So I killed the engine after a few minutes (3 or 4) started the engine back fan on low speed. Started driving again and transmission gage was bottomed out. Checked the digital readout and the transmission temp was 170. Continued to drive and transmission temp reached 180 after about 8 miles or so transmission gage began to slowly climb to normal. Any ides as to what is happening. I think one of the sensors is going bad but am afraid that if I continue to drive it I will be stranded if it ever goes into limp mode. Thanks fpr reading this long post and any ideas would be appreciated.
