Lol, I love how this thread was revived after being dead for 2 years. I'm at 45k on my 03 sedan and I just did my first oil change and changed my in cabin air filter. I plan on flushing the rear diff, tranny, and radiator myself soon. I save money, enjoy working on the G, and get cool new tools that'll come in handy down the line. Plus, you know exactly what was done to your car.

Is there a way to flush the tranny without owning the expensive flushing machine that the shops have?

Multiple fluid change.

I am also due for my 60k service. Got a quote from woodfield nissan in schaumburg, il for about $400 for all the work. Infiniti dealer where I bought the car was charging 800 bucks. I was like eff that! I think 400 is a good price, wish I had the tools and time to do it myself.
