Mainly while shifting {Auto Transmission} There is a very loud whining noise. I feel it may be getting worse. The car is warm so the fluid is warm. in some manual transmissions when cold you will have hard shifting and noises but this is a brand new car with an automatic 6 speed and warmed up when the noise is heard. In some cases the car will not shift correctly and the RPM's seem to go up before the shift process is done. SO, Has anyone else run into this? Am I the only person with a 2015 DART GT that seems to have a noise coming from the trans? Also the engine makes what I can only describe as a whippoorwill sound. This I think is due to the type of air intake system it has. This may be normal but I am not sure. I have had the car up to top speed or as far as I could to get all the feelings of the car and how it reacts. Is this something I would tell everyone to do? NO! I have racecar experience and have gone well over 280 MPH. Again this was done on a closed aircraft landing field. So why am I getting this noise? Someone might say well you shouldn't go that fast! If the car wasn't set up with a speed governor it would go faster then it does. Well I guess that's about it. If anyone has these troubles please feel free to E-Mail me. ripple251@hotmail.com Thank you.
