Ok so ive been reading a bunch of gear oil threads and i decide to order redlines ns for my tranny, after i order it im told dont use the ns because it doesnt have modifiers? so whats that mean? the description says that its good for your synchros i wont be using this in my rear end will that make any difference? or did i just blow 30 bucks on tranny oil along w/ the money i blew for the damn rp i bought that now everyone says dont use....getting kkinda pissed here...lol

I've been using Redline MT-90 for the transmission and and Redline 75W-90 Gear Oil for the rear differential. I believe the NS is for non-limited slip differentials and some specific racing applications.

I just add RedLine NS on mind. but my friends told me to flush it before it reach 1000 miles. Might give problem later with the clutch . I gonna put the MT-90 and the 70w-90 on mind tomorrow

NS wont hurt your clutch or trani.
costello has it right!

i was gonna say your clutch is a dry clutch no fluids go to it, but what else do you guys know about using the ns, i might use it if it wont mess ne thing up. *just in my tranny im using rp in the rearend

My understanding is that friction modifiers are used by the syncros
Using NS will make the transmission shift very poorly over time.

However, NS lube should be usable in our differentials because they are the Torsen type and do not require friction plates to work. Or am I wrong?

this is what it says sounds like it shouldnt hurt the synchros, so if we dont use it in the rear end shouldnt hurt anything?? worst case i guess i buy some more and try to send the old stuff back

75W90 NS


This GL-5-type geal oil doesn't contain the friction modifiers for limited-slip hypoid differentials. This makes the transmission synchronizers come to equal speeds more quickly, allowing faster shifting and much easier low-temperature shifting. Can also be used in racing limited-slip differentials where weak spring design causes too much wheel spin.

I'm confused

lol me too! i just want to know if i should use it or send it back.

The modifiers are for the Limited Slip Diff appications and can cause some GL5s to be too slick to properly speed the synchros, thus you need NS=Non Slip to ensure enough friction coeff exists. This is why others like myself have probably had poop shifting after trying Royal Purple, as it has those modifiers in it. Keep it, you got good stuff. MT90 is also good, but 75-90ns or even 140ns are great too.

cool thanks for the info, i got 75-140 to try out so i guess ill write up a review
