there is a sticker in your glove box go find the number that is like a gt4 or gu6 or something of that nature and that tells you what your gears are

there is a post in here somewhere that tells what they mean ill see if i can findit

also note if you have code G80 or not... awe hell, just bring all codes that start with a "G"

do you have the g80
even if you do it needs to be changed to an aftermarket posi
