automatic shift question

hey yall, im new here and i have question, i have a 2005 Honda Rubicon 500 that i bought used about a month ago. Here lately while using the automatic shifter, i noticed that i dont have to push the button in on the side, to slide it between Low, Drive, Neutral, and Reverse. Im always come to a complete stop before trying to change between L, D, N or R, but if i remember correctly i thought that when i first got it i had to bush the button in on the side to get out of gear. So my question is, Is there something wrong with the transmisison, or shifter, that i need to take it and get it fixed? or is it normal?

thanks,
chris
