Hi i have a 98 trans am ls1, it had the limited slip but i think its gone out. i just bought it it has 57000 mi on it so i dont know what caused it. but sometimes it will grab sometimes not. but it wont at all in cold weather. i tried replacing the fluid but that didnt help. my question is can i replace the clutches or do i have to replace the whole diff? whats the best to use? any help is great!
