Just an FYI, here's a picture of the differential and tranny drain plug after they're cleaned up. You can see the crush washers are actually not crushed at all. Save your money. There's no need to buy new ones and replace them like the manual says..

After I drained the differential, I went straight to the tranny. After that was drained, it was time to refill. Notice the nice little inexpensive pump I used. Some people use a suction gun. I prefer the pump because you just insert it directly into the bottle...
And again, here's the tranny drain plug after it's cleaned up. Whether it's dirty or not, it still won't have all the crude build up like the differential plug.

After everything was done and said, time to torque everything down.
I used 56 ft. lbs for the differential and 27 ft. lbs for the tranny....
That pretty much wraps it up. Enjoy the pics.

If you lie on your back between the tail pipes and scoot in a little you can access both the drain and fill plugs. As far as the washers are concerned, just inspect them and make sure they aren't gouged or bent in any manner prior to reinstallation.

crush washers can be flat. the material is a defined hardness and compress to form the proper seal. This is like head bolts that stretch a predetermined amount and should not be reused. When reused these devices provide altered and untested results. My only negative expericnce with drain plugs is volvo oil drain plug washers leak after the third use.

hrmm kinda went through this entire thread...and I wish I did before I had my transmission switched to Motul 300 75W90 GL-5...now some websites specify that the one i got is a SAE 75W90 ... is this still improper tranmissions fluid? should I start panicing?
(the top 100 questions chart on fluids lists: Genuine Nissan Transmission or GL-4 , Viscosicty SAE 75W-80, 75W-90)

Here is just another endorsement for doing this process yourself.
I went with the Redline mixture for the Tranny, and the straight redline gear oil for the Diff.
The most difficult part of the operation is getting the car on the jackstands...really.
The whole operation was a breeze. I didn't have any helpers (my wife ran at the smell of the differential fluid), so I did have to slide in an out to load up the pump gun, but other than that....no probs.

I really want to do this since I'm coming up on my 30000 miles but im still not sure with what what brand to go with...I'm not trying to spend an arm and a leg but I dont want anything cheap....and also if I have a base w/o LSD do I really need that hard core of diff oil. With all the different reviews of the stuff in this thread its making my decision hard...I can get Royal Purple locally at the pep-boys but someone had mentioned how it was bad. So I'm not sure what to do.
So for those of you who have used it, what are your impressions and to those who don't have LSD, what did you use in the diff?
Thanks guys

i just changed my diff fluid this past weekend to motul gear 300 and mannnnnnnnnn...shifts sooooooo much better!!! mad props to my boy masterj26 who took time out of his busy schedule to come give me a hand. i was surprised the diff only took 1 1/2 bottles of gear 300 to fill up. at 30k miles im going to use the other 4 1/2 bottles of gear 300 to change out my tranny fluid. great product and thanks Sharif for the recommendation!

The viscous LSD does not need the additive, as there are no clutches. Torsen-style (helical) LSDs don't need it either.

Viscous LSDs do have clutches but I think they are sealed from the gear oil.
