ok, i have a question; i bought a trans from the wrecker, it off a 91 integra ls i believe, according to s.c.c. the trans i.d is ys1, however on the actual sticker its says A1, which trans do i have? is it the same thing? in s.c.c it says a1's came in the jdm integra b16a, but i'm almost sure it is a usdm? anyhelp at all would be appreciated, thanks!
