The b16a tranny is a cable tranny. You need a hydraulic one. The only B series trannies that youw ant to stay away from are the old B20a5's from the old preludes, and any cable trannies. Other than that, they should all work dandy. If you do get a cable tranny, you can always get the cable/hydro conversion for a few hundred. And as a side note, gsr trannies are not cheap.
