Transmission blew up on car with 68k miles on it, and still owe $15k.

My 2019 Corolla's transmission just blew up, I still owe 15k on it, and it only has 68k miles on it. I have full coverage insurance, but I dont know if I would be able to submit a claim with it. I was quoted 7.8k to repair the vehicle, but I dont have that money, nor do I think it would be worth it. Basically restarting my payments.

What should I do?
