75W-90 “LS” in trans case - is this ok?

Hey everyone-

In my eagerness to get my TC fluid changed, I grabbed the two quarts of Mobil 1 synthetic 75W-90 I had in my garage and drained/filled the transfer case. Afterwards, I realized that I had used the “LS” variation of the fluid - presumably for a limited slip differential. I think I had this leftover from my old Grand Cherokee.

Is it bad to have put this in my TC? I haven’t driven it yet so I could swap it out again but figured I’d check the collective wisdom of this forum before dropped $30 on new fluid for new reason.

Thanks!

Edit: link to fluid info. Based on this info, it seems I might be ok.
