[R.O.B.]

If you are referring to the 2 tangs that are grooved on the converter, it feels like that's the only part that goes in. Hence why it's only about a half inch. I think I got something wrong with the converter, like I see the o-ring at the end of the shaft on the transmission, but when I look onto the converter, it looks like an open hole with some gear teeth on the sides. Like I don't see what that o-ring would attach to. Anyone got a good picture of the inside of a torque converter?
