Last night my buddies and i got done snowboarding with a nice fresh snow in the parking lot so we decided to do some drifting. i did a few donuts in first then powered out of it and just shifted normally into second at around 5500-6000 rpm when as soon as i tried to put it in second it started spitting at me and grinding so i just chilled for a second then i tried to put it back into first to just leave and it is totally blocked. like it wont even allow me to move into first gear at all. every other gear is perfect to get into and it doesnt grind or anything when i attempt first. what could be the problem?
