I just bought a 2009 G37X with 8000 miles on it. At around 1500 RPM whether gently braking or not it abruptly downshifts. This is an automatic transmission. It is quite annoying. I do not have the owners manual as dealer did not have one, unbelievable, I know after spending all that money. Therefore, I d not have info on the systems in this car with it's new technology. Wondering if anyone else has experienced this and if so what to do about it.Thanks!
