Last night when i was driving home last night i gunned my blazer around a car. it was pretty slick out and i began to spin out well a sec later i hooked and i felt some wheel hop and after that D was done. D is basically neutral now. But 1 and 2 are fine to take off when im still then i can manually shift into third and it will work but i cant go into D. What is going on with my tranny??

 

What trans is it?
