What kind of Rear Differential Fluid 03WRX?

[l2yan]

I have a 03 WRX with around 85k miles now and am doing a bit of a general maintenance overhaul and replacing quite a few of the fluids. One bit of information I cannot seem to find is what kind of Differential fluid my car takes. So if anyone would happen to know that, it would be greatly appreciated if someone could share. As far as the other fluids I'm doing I plan on doing the engine, 5W-30, and transmission oil. I'm not completely confident on the transmission oil information I found which is 3.7Quarts of 75W-90 (Have a 5sp), so if someone could correct me if I'm wrong on that I would greatly appreciate it.

Any advice appreciated, Thanks!

75w-90 is correct for the tranny. rear diff takes the same stuff.
