Do they ??

IF not how do i tell if its even a Y1, and how do it ell if it has LSD.

THANKS

 

LSD was an option. search how to find if you have LSD this has been covered MANY times. there should be a gold sticker on the tranny (if it didnt fall off) that will start with the trany code, I.E. Y1, S1, YS1. the sticker will be on the front of the tranny close to the block code but reading vertically.
