Transmission Slip Out Of Gear problems of the 2015 Ford F-150

The transmission drops out of gear and cannot be reengaged until vehicle is stopped shut off and restarted. Problem has increasingly gotten worse from a mild fail to engage after a three point turn around to current condition. Last most dramatic event occurred yesterday while on I-75 near lexington, pulling a travel trailer when it dropped out of sixth gear in a construction zone with a tractor trailer behind the truck. Vehicle went to idle, wrench light appeared. There was no throttle response and transmission would not reengage. Had to pull off the side of the road and shut vehicle down. Upon restarting transmission worked normally until reached destination. Two Ford dealerships have not been able to diagnose this problem. Only one error code has appeared, p0731. Transmission fluid was added and code was cleared. Problem was not resolved. Other dealership could not replicate problem with no codes present. Ford customer care has been contacted regarding this issue. Appointment made with local dealer. However, evident they do not know how to resolve.

I have been having an ongoing issue with my transmission, where it shifts rough or does not shift appropriately. When the truck shifts rough, I barely have my foot on the accelerator, where it will slam into gear causing the truck to jolt. I also have been experiencing the truck failing to downshift out of 4th gear while going uphills. While going uphills, the rpms will go below 1000, where the truck will begin to shutter as if it is going to stall. You are forced to press the accelerator in order for it to shift, where the rpms/turbo booster will soar. I have had the truck at the dealership for this concern, where they performed a software update and it did not fix the issue. I feel the transmission shifting rough could cause an accident, if the engine in fact stalls and you lose control of the vehicle. I also feel being forced to accelerate could cause you to strike the vehicle in front of you or lose control it this occurs while negotiating a turn etc. The panoramic sunroof allows water to pass the rubber seal and drain into the water track. I frequently have had the windows fog up from moisture inside the passenger compartment and the odor of mold. If you google "2015 Ford F-150 sunroof leaks", you will find 1000's of concerned Ford owners on forums experiencing the same issues, where Ford states it is normal for the sunroof to leak past the seal. I feel the sunroof is a health concern, as I believe mold may be growing in the truck and is being breathed in. I have been experiencing the seat back getting extremely hot while using the "cooled seat" feature. I feel this could cause a burn or fire hazard.
