i am in the middle of disassembling my auto trans and have came upon a "snap ring" that has no ears. it looks like an O with a tiny snippet removed. the bmw instructions specify using snap ring pliers to remove it, but i've never dealt with a no ear one. i though that the ring this size in the rebuild kit was not going to be used so i just went out and bought some generic snap ring pliers. please help this mechanical retard out. thanks
