Ok. Here's the deal: A while back I ordered my motor swap & paid extra for LSD tranny. The swap was supposed to come with either a S21 or Y21 tranny. According to the Honda transmission specs on here, neither of those are LSD. Anyway, the tranny was supposedly a Y21 with Kaaz LSD. It was definitely LSD, as far as Kaaz, I dunno. I sent it back because it sounded like shit. The guy said it was because it was clutch based instead of gear based. He said he'd send me a new tranny that is a gear based, LSD from the Honda factory- either a CTR or ITR tranny. I haven't installed the tranny yet, but I checked and it is LSD. Upon checking the sticker tonight, it says Y21. I know that just because that's the sticker that's stuck on there, it doesn't really mean that's what it is. Is there any code printed in the metal of the tranny so that I can find out exactly what I have??? Please help! Thanks!
