You are correct in that this transmission uses a specialty fluid that is NOT compatible with global/universal fluid types. This is a common misconception with those fluids since the name indicates that they should work on anything, however they are rather limited to the traditional type 3 and type 4 fluids and the many variants.
Your V6 Outlander uses a special transmission fluid referred to as J2 6 speed ATF. It is not safe to use any other fluid long term in this transmission.
When changing the transmission fluid you need to do a drain and fill and not
a flush on this model. The reason is that if you hook this up to a flush machine you will get cross contamination of the fluid from whatever is left over in the machine.
To perform the drain and fill, it is best to measure the amount you drain so that you can put the exact amount back in eliminating lengthy level check issues. Depending on the build date of the transmission you can use between just under 5 and just over 6 quarts of fluid during a drain and fill.
There is a drain plug directly on the bottom of the transmission for draining. Refill in through the dipstick tube, going slowly so that you don't back up the tube.
Your transfer case will take about a half a quart of GL5 hypoid gear oil (90W is recommended). You can use aftermarket fluid here if you wish, Drain from the drain plug directly on the bottom, and refill through the fill hole on the passenger side oupper half of the transfer case. Use a fluid transfer pump to get the fluid in (no room to pour it in), and when the fluid runs out from being level with the fill hole, the case is at the correct level.
Your rear differential will take another half quart of the same GL5 hypoid gear oil, 80W is recommended.
Again the drain plug is right on the bottom and the fill hole is half way up the back of the differential. Use a transfer pump to fill the differential until fluid comes out the fill hole from being level with it, indicating it is full.
I do not have a suitable diagram of the rear differential drain and fill points, however they are not difficult to find either. The only catch is that depending on your build date, instead of regular bolts it may have Hex plugs, requiring a Hex bit to remove (Normally a 10mm Hex).
If you have any questions at all please just let me know and I would be happy to elaborate.
