Traveller (TSC) 80W-90 gear oil

[fried1765]

Is it acceptable (satisfactory) to use Traveller 80W-90 (GL-5) oil in the front axle of my 2006 L48 TLB.
I have no idea what the previous owner used.
Perhaps, SUDT, or even SUDT-2 is in there now..
Can 80W-90 ( GL-5 ) be added, or mixed with,...... possibly existing SUDT/SUDT-2?
Or,.......should I just add SUDT-2, assuming that MIGHT be what is already in there?

Gear oil and UDT2 both have a distinct odor. UDT2 almost smells sweet.

Yes its acceptable to drain and refill with a Gl5 gear oil. It wont hurt to mix them but personally I would go the replace route. Gear oil will smell.of sulpher and at ambient temperature will appear much "thicker"
