I recently purchased a 2006 G35 with just over 100 000 km (60k miles). I don't know when the transmission fluid was last changed so I would like to change it out. I inspected the fluid and it is dark but no foul smells.
The owner's manual prescribes Nissan J-Matic ATF. This was superceeded to S-Matic a few years back. I can get the S-Matic at the local Nissan dealer for around $14 a quart. My question is whether I can use generic ATF. I have some leftover unused Valvoline Maxlife that I used in a previous car that states on the back that it can be used in Nissan/Infiniti where J or S Matic are called for. The Infiniti forums seem to think I'll destroy my transmission if I don't use the Nissan fluid but I don't buy that. Can I use generic fluid or is it safer to stick to OEM fluid for my application?
