I have a buddy who works at a Nissan dealership and gets me really cheap labor fees, that being said my 07 g35 4 door is approaching 95k miles. he recommended I do a transmission, coolant and injection flush. Should I go ahead and to this also what about a differential flush. Thanks for the sound advice.

 

Go by what the manual recomends. Im sure your buddy at nissan knows what needs to be done! I bought my 05X from anissan dealership. They thru in a warranty to 126,000 miles. It had 85,650 on the clock. They had all the service records since new. My X is well maintained. They knew it was in great condition. It was the 5th car l bought from them. Classic nissan in hainesport nj is a good dealership to buy from! Im in Ga now. Augusta infiniti is my new dealership.

 

As stated just follow the manual. I did all of those items plus around 60k, Now at 83k and will be looking towards the next service need to maintain.

 

Flush or drain and fill? I have done drain/fill on coolant and transmission but would be leary of a transmission flush with a machine.

 

Maybe you should just do 100k mile service. Your car will run better and if you haven't done the TB cleaning you should do that as well. I did all my services out of order when i did upgrades to the car.

 

I'd go ahead and include the plugs. They're rated for 105K, but since you're close and planning on going big anyway, toss them in too.
