Alright guy's I did a search and read. In the end I could not find a straight answer. I have a b18C1 that I swapped into my ef and a JDM LSD Y1 tranny from password JDM. Now of course it has the infamous 3rd-4th grind and I was wondering someting. I still have the s80 tranny from when my B18 was in my eg. Will the internals from the S80 Hydro fit in the Y1 Cable tranny? If so what will I need to do it? I have ripped apart my trannies before so that is not a problem. I just need to know if the parts will fit. Thanks again!!!
