There is no warning light for any of the drivetrain fluids. You might get a ses light if the fluid temp ever gets too high in one of the parts, which itself i'm not sure about, but that's about it.

I just changed my front differential fuild earlier today and replace them with Fullsythetic Gear oil 70-95w Mobil1. Notice the old oil was very nasty look, it seems worst than the gear diff old one. I would suggest to everyone to change them if you can I don't think the oil is in it for lifetime
