Thread: Need help figuring out what is wrong with my 04 gp gtp comp-g PLEASE READ

so when I started my car this morning, I was halfway to school when the car shifted into another gear (probably second) really hard. It then told me that my traction and stability control went out and to service my stablilty system. I also noticed that my cruise control stopped working too. Any suggestions as to what could be wrong? I think it's a computer thing but I'm not for sure

Kinda lost on this one. any other problems you noticed?
