You get an impression of if you listen to a dogbox or sequential gearbox which use straight cut gears. These sounds are extremely and everything is fine, it's simply its working noise.
Now think of a standard gearbox, there are also internal parts (gears, bearings, shafts, synchros, shifting couplings & diff) that have more or less working noises.
Not every Hyundai gearbox sounds the same, not every listener hears things with the same intensity and rating of it.
In my case the Powerflex did a slight change, but also changed to Redline MT-LV before, without a change on gearbox working impression.
When I trash in 1. or 2. gear pedal to the metal in a serpentine, I have no concentration to listen. But I will keep an ear on it. So excessively steering angles is very difficult for me in low speeds, regular I don't do this maybe while driving in a parking lot.
If you talking about using the steering wheel, while not driving? This is what I never do only on a rental or a daily shit box with 155-175 wide tires, because this is one of the biggest stress scenarios that you can do on the materials.
