short story: I track my 2018 gt350, not racing nor time event. Nothing was done to the trans (Just FP knob). I have a 5th gear grinding, took it to the dealership, and they denied my warranty for racing. 2 months later (second track event after gear grinding), the transmission overheated in 10 mins. It keeps happening for the rest of my 3 track events. Took the car to another dealer and they said Ford denied my warranty for racing. I called Ford customer service and only gave me a case number, and it won't do anything. I'm not doing tracks until the car is fixed. I really need some help here guys....Thanks long story: I was traveling to Canada in April, and I was exiting the highway, and I downshifted from 6 gear to 5th and then 4th, and I couldn't shift into the 4th gear. And I tried 3rd 2nd and 1 st gear, it won't even shift into those gears. And I realized there is a problem with my clutch or transmission. After a red light stop, everything works fine, but my 5th gear stared grinding. I do have a chat history with my friends to prove the date and what happened. Then I took the car to a dealership. They denied my warranty for racing. And I keep telling them it's not racing and ford claims the car is cover for track use, but they won't listen. FYI, 5th gear is barley used on track, mostly 2nd and 3rd. So I don't know why the gears I use the most didn't fail, but a gear I barley used failed, and the reason from ford is racing. And the dealership told me that ford told them the car is track-ready, but it's not track warranty ready. And they also told me having my hand brakes engaged during winter can cause brake rotor to crack. But the hand brake on this car is a drum brake, so it will not touch the rotor. The reason I am mentioning this is that I had cracks on rotors and was trying to replace the rotors under warranty, I knew a lot of people had their rotors replaced under warranty. Well, it was not my mean concern. This can also prove the dealership doesn't know what they are talking about. So I called Ford customer service, and they said I should bring the car to a different dealership, so I made an appointment for July. Then I had a track day after I took the car back from the dealership, the transmission did not overheat. Then my next track day was in June, and my transmission started overheating. So I assumed it was caused by 5th gear grinding. And the second dealership told me it was ford denied my warranty, not the dealership.
