Popping when putting in reverse issue?

Okay so I haven't had my jeep very long, it's a 2002 TJ. Anyways when I put it in reverse a loud pop is heard and the car bounces a little. When I got the car I had a mechanic look it over and asked him about the pop and he said it's fine, but it still makes me nervous. Anybody else have this? Anybody know what this is? Good or bad? Any input is appreciated.

Does it pop when movement in reverse starts or when you're shifting in reverse? If it's at the reverse movement then check your control arm bushings. It's not a car is a Jeep.

Not when I drive, but when I put it in reverse gear.

So you're saying immediately upon putting it in reverse you hear a pop? And as asked is it an auto or manual? Does the Pop sound when you take your foot off the clutch or brake? Have you checked the integrity of your transmission mount?

Automatic transmission. When I move the stick into the reverse position it pops. The whole vehicle bounces slightly.

I have my foot on the brake, grab the stick, press the button pull stick back to reverse, as it reaches the reverse position the vehicle bounces and a pop is heard, this is before I even release the brake or move the vehicle.

I had that with a Ford, popping in reverse. It was the torque converter if I remember correctly. But it was also having tons of issues with forward as well. So it wasn't simply the pop you are referring to.

After it is warmed up does it still do this?
I get some movement when the Jeep is cold, always going to get a little movement as there it always wants to go forward or backward depending on reverse or drive.
Cold engine has higher RPM to warm it, so it is more pronounced when shifting into a gear.

Have you checked your transmission mount? You'll need at least one Jack and a couple of jackstands to support the transfer case and the transmission as you drop your skid plate.

I'll have to pay attention to the popping as the engine warms up. No I haven't checked the transmission mount, I'm also leaking what I presume is brake fluid. I'll be honest I'm a high schooler and I'm not that mechanically inclined. I build robots, but haven't ventured into anything with cars except removing doors and tops. I'm probably taking it to a family friend who is a mechanic over the weekend. Thanks guys.
