im looking for a trans for my 97 gsr and i was on ebay where a guy had a ys1 lsd hydro trans listed but the picture of the code sticker says y21 whats the difference other than cable and hydro ive never even heard of a y21 JDMCars.com filled me in a little bit but im still curious of what they came in and how one may be found im guessing maybe they are jdm xsi transmissions.
some one help me out
