I have the same problem with my 2009 Dodge Journey SE V4 40,000MILES on it.....I can hear this whistling noise when driving at 65mil.......... if i increase or decrease the speed the noise goes away, i'm 100% sure that this noise comes from the transmission, because when i reduce the speed and the transmission shifts back the RPM increase, making the vehicle shake every shift.
I have not take my SUV to the dealer yet, because i don't know if this is normal for this car, however sometimes i feel like im driving an old yunk car...
my wife has a 2001 Dodge Caravan with 178000 miles and we do not have these problems.
