It does kinda look like one, but its extremely heavy duty compared to the one you linked or the others I found with a quick search.
The handle/push part is either cast iron or low quality steel and is solid, The guide part looks to be either stainless or a high quality steel.
Its one of those things you hold and say to yourself, 'wow, that's pretty heavy'
I guess its not impossible that its some kind of super heavy industrial bait punch, but really doesn't seem like it is.
The toolbox I found it in had quite a lot of transmission specialty tools, fair amount of general tools and some odd ball stuff.
I work at a trans shop and nobody recognizes it.
It seems like it is a driver/installer of some kind, though the handle/driver has never been hit with a hammer from the looks of it.
