trans. temp warning @ sustained high speeds?

[EricEst1978]

The following scenario is a fictional/hypothetical scenario and his being used for educational purposes.

Once upon a time, a man was driving his Gen 2 raptor from Dallas to Austin one weekend. During the drive, our noble hero was blessed with a few sections of wide open road, with very few other vehicles in sight. If our hero had the wind at his back, and managed to sustain speeds nearing 100mph, for a period of 10-15 minutes, would it be normal for the vehicle to peg the transmission temp gauge and throw a warning, before dropping back down to the median range fairly quickly following deceleration, when the vehicle was allowed to resume a cruising speed of 80'ish mph?

Thanks in advance for reading and responding to this riveting tale.

Does our hero have anything in front of the grill like LP9s?

A similar hero has done that drive and has theoretically averaged over 100mph for a similar period with NO trans temp warnings nor movement of the gauge.

I've had PLENTY of high speed runs for sustained periods of time and no warnings, that is weird. Were you er' they holding it in a lower gear by chance?

Low fluid or lights blocking the grill are my bet.

Has the transmission been serviced (drain/refill) at any point to your knowledge? These transmissions are very sensitive to the correct fluid level. If the dealer/shop overfilled it you’ll have symptoms of overheating under load and possible fluid venting.

Your here should def. get it checked out. Best I can do is compare a sustained 90-95mph for about 45 minutes. It’s what the DPS trooper were doing, and everyone else around them, so if you were under 85, you were getting the stink eye. No problems to report.

My money is with @FordTechOne ; previous service or the dreaded flush...
