For 6MT: How often do I have to change the transmission and diff oil?
Mine is like molasses in the cold. I think it's almost to thick. I will probably change my fluids before the big trip in May. Clutch, Brake, Diff, Trans, unless i dig through the previous records and find it was done before
For the guy who asked for rear diff DIY its HERE thanks to soundmike.
Besides that all of you AT people should really consider staying with Nissan MaticS ATF to avoid getting your warranty voided, as discussed many times before nissan has in fact posted a TSB out there a long time back which says exactly this, so make your decision accordingly...

Per owner's manual:
DIFF:
Genuine NISSAN Differential Oil Hypoid Super GL-5 80W-90 or API GL-5 Viscosity SAE 80W-90 (*6)
note: (*6) ==> For hot climates, viscosity SAE 90 is suitable for ambient temperatures above 32°F (0°C).
Manual Tranny:
Genuine NISSAN Manual Transmission Fluid (MTF)
HQ Multi 75W-85 or API GL-4, Viscosity SAE 75W-85 or 75W-90
The critical factor is the GL -#. If you get it wrong on your tranny, you can mess up your snchros. If you get it wrong on your diff, you can wear your R&P. (btw, the viscous LSD within the diff is separately sealed with its own lube and is not serviceable)
When I did my 6mt Tran and Diff oil change, I kept the Nissan OEM 75W-85 transmission oil but went with the Amsoil Severe Gear 75w-90 Diff oil. The Nissan transmissions are really sensitive to what oil you use and tend to be "notchy" in the cold with other oils.
I recently did it @ 48k. Changed the MT (OEM MT) and Rear Diff (Lucas Oil 80/90) while doing the engine oil. I believe 30k is the interval for MT but the Rear was optional. Since the car was on all 4 jack stands, might as well do it all! After the change, the tranny feels smooth and did notice a better transition from the rear. Doing the Rear requires a second person (If your funnel does not have a proper nozzle tip that will stay in place of the drain plug hole)... One to pour the fluids into the funnel and the other holding the clear tube in place at the diff. Since I did it myself, had to pull a Macgyver and rigged an IV Drip system using what I had in the garage.

u can change diff fluid yourself without help, almost all fluid pumps in car stores nowadays have rigged clips on the tip to keep it from coming out of the fill hole when pumping new fluid in.
I went already second time diff rear, Motul 90PA and performance increased significally! in engine i use also Motul 8100 Eco Lite 5w30, interval 4000 -5000 miles. in 6 speed man. tranny i use 75W85 Nissan KE916-99931 OEM tranny oil. 2.9L.
