I just changed out the manual transmission fluid in a new to me Jeep Wrangler. 1997 with the 4.0 and an AX-15 transmission and 144k miles. I ordered 4 quarts of MT-90 from Amazon. About halfway through refilling it I noticed that Amazon sent me two quarts of MT-90 and two quarts of 75w90, all from Redline. Very similar looking bottles. I've got about two quarts of 75w90 and about a quart and a half of MT-90 in there now. I can always drain and refill soon but if this mix is ok for a while I don't mind leaving it instead of dumping out close to $60 of fluid if I don't need to. Any advice?

Yet another reason why I detest mail order shopping. The only thing I'd be worried about is if your car specifically specs GL4 only because of sensitive yellow metal synchros. LS additives can wreak havoc with shiftability in *some* manual transmissions not designed for it,causing gear crunch/grind when shifting.
What does the 75w90 bottle say?? If the bottle says 75w90 NS then I believe the difference is that the NS is lacking friction modifiers and is a GL-5 product versus the GL-4 MT-90. The 75w90 NS product ( if that's what it is ) is also more application-specific than the MT-90 so I might be hesitant even if I could get away with it.
I'd want to verify what you have listed is 75w90 MTF or differential oil??

I think that's your best bet...the 75w90 is differential oil with the MT-90 being a totally different product. That would qualify as a misshipment in my book. Hope it works out for you.
If Amazon makes it right then you get a free flush and fill

This is not an MTL as others have stated.
Each type of oil for each application has a different additive package.
