I got a Lancer ES 2008, Automatic transmission, when im driving it a strange sound goes out, i realized it only appears when im driving it, not when the car is turned on parked, it has 71,000 miles, the sound gets louder when i accelerate and increase speed. I suppose its a transmission problem, Ive searched the diferent TSB but no results, i hope you can help me with this.

 

Take it to the dealer, 100k mile powertrain warranty.
