We all know the transmission takes ATF-SP-III. thats allright.
But there is also a differential there. Does it has seperate box and it takes Valvoline 75w 90 oil there?
Cause i never did it. I changed many times transmission ATF oil , but never differential oil.
If anyone has done this work in a garage please inform me.
on auto boxes F4A22 and KM175-5 below transmission you can see clearly 2 different plugs for changing oil.
