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...

 

Which Diff oil is recommend by the dealer? Same as the MT? I plan to pick it up at the Nissan dealership.

 

No, the diff and manual tranny use different oil.

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)

 

I have a question if you dont do diff oil on time like you suppose.. lets say 70 000 miles later is there anything i should beside changing the oil. Samething for radiator..:0(

 

Def do the differential fluid! i did mine a week or so ago and that sh*t was dirt mcgurt!

 

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.

 

OEM Nissan in the tranny and Redline in the diff. Change every 30k.

 

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.

 

^^ +1 on the pump.

StaLube even sold bottles that came with a pump.

 

Hey guys I got a 03 5AT sedan did a diff swap not long ago so that fluid is changed. My last tranny change was at 120k now I'm at 165k time to change??

 

^ might as well. Recommended is every 30K from what I've read.
