Hello, Thanks.... Yes I can turn it. I have been pondering welding up some sort of an attachment to connect to my slide hammer....but I have thought against it for now and wanted to get some advice before I go and damage something. I don't imagine using a hammer action in any way on something like an auto trans. is a very good idea.

I went back out after posting to try to work at it gently again but have had no luck.
Is there something that needs to line up in behind there before it can be pulled.?
Like I said it will come out quite a ways and then it is stuck. It almost seems to be a little bit harder to turn after it does come out a ways. (Like it is catching on something or the ears on the converter are dragging a bit on the inner bell housing casting) If I push it back a wee bit then it turns o.k. If I push it back all the way in it turns very smooth.

It really seems to me that it is nearly out but I really don't want to force anything to much.
The converter is perhaps encountering what you describe as being hung up on a bit of a groove. I will try to lift it a bit as I pull. Already smashed a finger between the converter ear and inner bellhousing. Going back out after some ice. Thanks again for your quick response.
