Input shaft 904 is this cracked or is it made like that

I might have to put it back in for now and just not run the car. It’s not a big deal for me to pull the engine again. I have to be able to at least move the car
If I can find a good converter I’ll do that and put a new gasket behind that pump the first time.

I know the deal now and what it could cause. Yes.....that hub is shot. The crack alone will get worse and the parts will separate and grenade the transmission.

Looking at the bushing. It is shot. Despite the look of the hub being worn. It’s still not grooved. I’m hoping it’s didn’t do damage to the internal pump. If it did I’ll have to replace that.

What I’m wondering is why it got so hot.
That bushing is shot but the heat discoloration isn’t in the area of the bushing.

It’s in the area of the internal pump. What could cause that. It is locked into those tangs. Maybe there is play there and the tangs are worn down.....

What made this thing get so hot?

This is the original converter.
It probably didn’t break because I haven’t driven the car much at all before I had the engine back out and rechecked it. Except it wasn’t like this last time..

Are you going to use that scored up transmission input shaft? I cannot believe these guys are advising you ro reuse that. No way in heck would I do it. That transmission would be coming slam apart. I can see no amount of advice is going to get you to actually repair it. Especially since you bought an 84 dollar torque converter. Some things are worth stepping up "a little bit" on.

I wish you luck.
