Hey... Just bought a 2019 Rubicon. I have little over 600km on it now. It's manual shift. Was fine when I first got it but now it has a rattle and when shifting it's very clunky. Rattles the most in 4th and 5th at certain rpms. When it's rattling if u hold slightly up on the shifter the rattle will go away. Also in 4x4 it doesn't rattle. The rattle is so much that it is annoying. It goes in for a service in another week but really would like to know what's going on. Any help would be great. Thanks.
