Hey guys I'm new to the forum but not to the world of the lovely G37. I bought a used 2013 G37x sedan in May 2017 with 23,5xx miles on it. Now it has 44,515 miles.I wanted to spoil my car a bit and change out some of the PSF utilizing the syringe method which I did. I took out and replaced about a pint of PSF (ATF) using Royal Purple Max ATF (which on the bottle states it is Matic-J Compatible) and I just want to make sure I didn't use the incorrect fluid. Before you say anything yes I should've asked before I did it lol. The car seems to be turning quite nicely actually and so far I seem pretty happy with the results. Thanks!

 

IIRC as long as it's Dextron 6, you should be good

 

Its uses atf so any synthetic atf will work. I use a turkey baster if I dont use my motiv extractor and suction out as much as I can and refill it. Then do it again a week later and once more if original fluid is more brown than red. This method works for brake fluid as well.

 

Thanks very much for the insight!
