Thanks, I have the transmix z. So that's the attesa and transfercase out of the way
(one shop in town had it)
And they recommend castrol axle EPX 80-90 for the front and rear? Haven't opened it yet because I feel sus about it. And also they said that I don't need to change the gearbox fluid..... So that makes me think they don't know. Just going off that fluids chat on the computer. And I don't really bother because the aren't and er34 gt-fours listed... Then he told me that my car is rwd.. But yeah, it is manual. Iv had it for 7 years. It's not crunching into gears, it's just getting hard to select reverse and 1st when cold. Think it could be all factory fluid. Because when I first got it I was the second owner in Oz the previous owner had it for a year, and when I first got it, it had a big ass blue oil filter with Japanese over it. Old dirty spark plugs.
