Clicking noise when rolling backwards in drive

My new Four runner clicks after shifting from reverse to drive if it rolls backward a bit when enough pressure is not applied to the brake. It also happens
when rolling backward on a hill when waiting for traffic conditions to clear so you can gas it and move forward. You can't always break and gas simultaneously on a incline and the result is clicking or grinding of gears sign. Is something wrong?

 

I have gotten a similar noise, although mine may be different. Mine almost seems like ABS chatter when i am backing up (out of my driveway for instance) and then put it in drive. It is intermittent and im not sure I could force duplication.

 

nothings wrong, i know my 4th gen does that sometimes, its the abs coming on to stop you, I know for my 4runner if i let it continue to roll backwards it would eventually stop itself
