Jingling in Stick Shift

Hi everyone, I purchased a brand new 2014 JK about 2 months ago. I've noticed recently that when shifting I hear a 'jingling' coming from the stick shift area. It happens almost always in 1st and 2nd gear, but goes away in higher gears. It gets louder with how hard I accelerate. I don't think it is coming from the engine because when I rev the engine in neutral there is no sound. When I hold the stick firmly in those gears I mentioned it does get slightly lessened. Anyone have ideas as to what this could be? Kind of frustrating since it is brand new. Thanks for your help in advance!
