im not sure that u could tell what year the tranny itself is, what kind of tranny is it? is it a b16, b18, or b20, or a d-series, f-series, or h-series tranny, if its a b-series im pretty sure that its a hydro tranny. and if its a hydro tranny, im also pretty sure it has to be at least a 94 or above. sorry for the lack of help, at this point thats all i can do for u. good luck.
