Hello all,

I have a 2005 G35 Sedan. Got it back in 06 with 69K on it. By mid summer 2010 car was at 130K. Since then, we put almost 50K on it. Most these miles are highway miles. Car runs fine. If you gun it, about 5-6k rev seems to pause for a mini sec. I can't remember if that's normal or not.

First, I need everyone to drop all your stones before I say this. We never did a automatic transmission service since we got the car. My mechanic test drove it and says she runs very well. Says the shifting is fine to him. He believes the service won't affect the car. All transmission shops I have spoken to say the opposite. Maybe on a fine line, they don't wanna be liable if something does happen after a service.

So, my question is, "What would you do"?

 

Service, preventative maintenance. In your mechanics eyes he sees no problems to be fixed, in my eyes I see the possibility of avoiding a problem.

 

We've heard issue with members doing a "Flush" after so many miles without service. I'd do a drain/fill and see what kind of reaction you get. If it feels better do a drain/fill along with your oil changes for the next several months. This won't put your trans in shock and it should shift close to new. Only use the Nissan recommended trans fluid!

Is the drain and fill where you drop the pan and replace the pan gasket? Not the bypass machine at oil changing shops right? Thanks

 

You can remove the pan and replace the gasket if you want but I wouldnt mess around with the gasket etc if it doenst need to be replaced.
Follow this is the drain and fill procedure as its the safest one:

^ Gasket should be changed anytime you remove it but people choose not to. Its very easy to replace so I am not sure why you would say " I wouldn't mess around with the gasket " you scrape off the old one and put the new one on. Its better to replace it than to have a leak imo.

 

With the method above there is no removal of the oil pan.
If he is removing the pan then I would change the gasket, obviously.
I'm not saying it should never be removed.
And most people choose not to change the gaskets because they dont leak that often and its not needed whereas the AT fluid service is required item.
