So got a used but rebuilt transmission and wanted to see if anyone can help identify the converter. Probably a rebuilt stock but thought i would see what everyone else thinks. Google/AI wasnt much help. Its painted gray and gas #5 between each eaised area on the top curved area. Did find a machine stamp that may give some clue. One other thing was a paint stamp but not super clear pictures attatched.

 

Reman hs 1800 to 2000 rpm provided housing used and a previous assembly sometimes they are not.
