I bumped a thread in maintenance asking this but didn't get an answer in a week. Search has general answers to transfluid (mostly MT-90 related) but are not specific to the factory LSD and I have no local motul dealer. I understand the LSD does make a difference. Motul has Gear 300, and 300LS. Which should I get? Sector sells 300LS. One post on here mentioned that maybe the factory lsd didn't need the 300ls friction modifier. That's what got me to thinking I need to find out. Any thoughts? Thanks.
