I asked a Transmission guy who works on every car known to man and he says if people changed their t-oil every 20,000 miles, you are very unlikely to ever have any issues. Since I am selling my G6 and driving a Murano :-( with the dubious CVT issues, I am going to do that. Don't tak my word for it, and it probably depends on how you drive it - I used to drive the G6 pretty hard.So its 100k miles before changing the 07 g6 trans fluid filter service? Drop the pan and 7 quarts of synthetic dexron 6 fluid?
So its every 50k miles change trans fluid on the 3.5liter v6 g6 transmission?
