Im looking at swapping my diff and autobox oils and have decided to go for royal purple off the back of the recent thread that made it sound good. Autobox isnt a priority but would be nice to get done whilst the cars on a lift.

 

After searching the castrol website ive found the following and wanted to check its correct before going head long into it :

 

Diff oil 2.1 litres as 75w90 ? (this sound correct?)

Autobox 8.7litres as dexron 3?

 

Also had a search on "how-tos" and found one http://www.ttzd.com/ here, but the pictures are not great. Just wondered if anyone had any clearer pictures or tips before i get into doing this job. (appart from taking the plug on the side off before the drain plug...)

 

cheers all, during this job il be trying to get some really clear pictures and add it as a faq if theres interest

diff oil = 2.1 nissan recommend 80w90 but most people do use 75w90 so its ok, autobox = 8.7 litres dexron 2 but to drain all that you have to undo the torque converter as well other wise you will only drain approx 3.5 litres from the auto sump, dont forget to clean the oil strainer/filter. changing the diff oil is very easy only took me approx 10 mins to undo both plugs spray both with plenty of wd40 then use a 1/2" rachet extension to undo them right plug= fill plug & left plug= drain hope this makes sense.

oh right hadnt thought about the added complecation of an auto box. I take it theres no point in just swapping out the 3.5 l or so without draining the tq converter ?

 

I might hold off on the auto box myself and wait until someone that knows what they are doing is available to do it. Il get ordering my 2.1l of purple for the diff in the mean time.. 75w90 it is then i guess....
