J is the only fluid available in my neck of the woods. When I say its superceded by S, I get a 'deer in the headlights' look.jspitz wrote:Tech,
So would you recommend J or S for our vehicles, and is J even available anymore? NTB08-049b says to use Matic J if Matic S is not available for 5 speed RWD ATs. I know the mechanic that did my flush used something like 13 quarts of S on my 60k service. I think the Nissan dealer just did a dump and refill at the 30k, but I don't know offhand if it was J or S.
Any truth to J being corrosive and potentially being the issue?
Thanks for the inside scoop!
