In a 2008 G35x, what is the recommended change interval for transmission fluid flush and coolant change? Are 60k mile intervals ok?

 

This is all covered in the Owner Manual found here for free: http://x.infinitihelp.com/forum/local_links.php?catid=2

 

The only thing that needs flushing is a toilet! Only time a trans needs flushing is around 100K miles and even Nissan can't make up their mind about that. Drain and fill is what needs to be completed every 30K miles on all fluids, according to Nissan. If you live in a hot climate like SoCal it wouldn't hurt to do the trans drain and fill more often....Gary

 

i do a drain and fill. flush has the chance of forcing contaminants up into the transmission and causing damage.
