What did i do to my trany? I was pulling in to stop going about 5 mph, and i heard this awfull clang, but i thought i just hit a dog or something. so i parked, went inside, came back out later. Got in the car put it in reverse and it slipped and didnt move then it caught and jerked backwards and started slipping and didnt move any more. then it did it again. When i put it in neutral it made a terrible grining noise like grinding gears in a standard. Then when i drove it in drive it would jerk the power and sometimes gring. I am probably taking it to amco tomorow. Anybody know what could be going on here??

Thanks
