Does this converter hub wear pattern look like a worn pump bushing?

Can anyone on here read the wear patten on a torque converter for me? This is from a 700r4.

I was having issues with fluid leaking somewhere inside the bellhousing area. We replaced the seal and it didnt fix it. We tried to look for cracks in the converter and couldnt find anything. We looked around the pump and it doesnt appear to be leaking from there. The new seal still looks good. Im not talking about a small leak, Im talking about a big one. It dumps fluid out when the motor is running, it runs down both sides of the bellhousing (inside) and gets slung across the floor.

When we were looking at the converter hub, the wear pattern on it looks weird to me. The ring around the hub that has been "polished" doesnt look like I would expect. I would think that it would go around the entire hub at the same depth. However if you look at mine, on one side of the hub, the polished part dips lower on the hub. I have no idea what causes these wear marks, I was just hoping someone on here did and could tell me if something looks wrong. We are having a heck of time trying to find this massive leak.

Thanks

Here are some pics:









I have had a few guys mention that it looked like the pump bushing is worn out and it is letting the converter wobble which would in turn let fluid leak around the seal. The transmission and converter have less than 5k miles on a rebuild.

Any insight? Thanks guys.

I bet the halves of the pump aren't aligned, distorting the bushing.

I heard this as well.

Is this something that a transmission place could easily fix?
