I resently bought a tranny from a guy I didn't even know, but for $200 it should be worth it no matter what it is. He told me it was a automatic JDM SiR-2 from a b16 and I'm not sure if it's true or not. I have only done one other swap and I'm trying to finish this one now. Is it true that any b-series tranny will fit almost any b-series motor? Any tips on my swap would be appriciated. I bought a 90 Integra b18a and I'm swapping it into my 92 civic dx 4drw/auto tranny. Will this tranny fit the b18a motor? Plz help, I can't wait to get this one done. Thanks
