I wouldn't screw with it. My G20 had never had its fluid changed that I know of, and at 110K miles I had it changed as I was told import cars were different that domestics (I was new to the import world then) and that you can change fluid in the transmissions without it screwing things up. Well, I liked the little car and it had done well for a few weeks and I wanted to treat it, so I had them (dealership) drain and re-fill. No flush, just a fluid swap. It died at 115K miles. Slipping horrible, etc. Now I have heard that if you do it every 15-30K miles when new, this won't happen, but the manufacturer says not to, so why the hell would I?
My 2001 WS6 was a 6-speed, and I had the fluid in it changed (@75K miles). It didn't have any problems afterward, but it never shifted as smoothly in my opinion.
So I'm just not a fan of messing with it.
Just because it LOOKS dirty doesn't mean it's not working just fine. Anyone who has ever checked the oil on a diesel can tell you that.
Nissan says not to screw with it. Do you really think their master-plan is to have your transmission go out at the 100K mile-mark and that's to be their big money-maker? Seriously? Just don't **** with it.
