Alright in a couple weeks i have to make a run up to Detroit from OKC by the time i get back itll be just over 100K on the meter so i was gonna have the tranny fluid changed out probably try and add the the Transgo shift kit while I am at now i know i need to use Nissan fluid for that my question is more along the lines if i have to use a special fluid for the rear diff and how much fluid do i need for it thanks in advance for the help

 

I used Mobil 1 75W-90 and about two bottles of it. Pop the fill plug first PRIOR to draining it also having a vacuum or pump device is a must!

 

coffeysm thank you for the help on this did you flush it at all after the vacuum

 

When I say pump or vacuum I mean something to push the fluid back into the diff. I used a Motive power bleeder that I have, but you can pick something up for like 10 bucks. Just clean the drain plug off and you should be good.

 

If your trans is shifting like intended why waste your $$ on the Transgo kit? Changing trans/differential fluid is a good idea, don't forget to check your belts and do a drain/fill on your radiator fluid if it hasn't been done within the last year...Gary

 

Are you serious?
