Hello, Were you able to find out why the overdrive was making noise? Was it something inside the transmission?

It is normal lol when you put it on awd, cuz what happen the sensors wont let you go faster that certain revolutions and they automatically stop the vehicule to maintain the speed very low, try to push the button awd once or take it to the dealer so they can reset the code or fix any bad sensor, good luck..
