Hey guys. Is it necessary to change out the factory transmission fluid for something like redline or royal purple on these cars when taking them to the track? I only have 2,000 miles right now if that matters.

 

Not really, but a good synthetic like amsoil GL4 is nice. I would do it anyhow, since your tranny is broken in now.

 

I've got about 4,000 track miles on my 350Z and I use the factory Nissan trans fluild and have changed it twice.

 

I have 64,000 miles and haven't changed mine. Is it pretty simple to do? Where do you fill it from?

 

I track my car regularly(usually once a month when economy was good)
i have one of the few auto trans Z's that runs the car on the track and
i use the royal purple trans fluid-stock fluid was getting too hot and not
allowing it to shift properly-once i got the fluid it improved dramatically.
I still may get a trans cooler later.
