You could crack it open and count the various teeth.
However, for $50 I would get it for a paper weight.

 

why would i do that, the tranny man checked it out already and it just needs a case, i have case that i can use in the garage?????????? i just need to make sure it is a gsr or a b16 tranny before i even mess with doing it
