Seen this in your Jeep!!
Stalls when I shift in reverse or drive.
Stalls for second when I hit a bump!
Will not shift until I let off peddle
(rpm continue to climb,will not shift,then I lift my foot off peddle then it shifts)
Transmission range sensor????
Thanks!!!

 

could be the range sensor. has the jeep been sitting for a while outside?

 

Did the range sensor CEL come on. You can try Colin gears a couple time while sittin still. Go down to 1 then each one at a time in easy flow movement. The range sensor is pretty much the NSS. Tell the jeep what hear your in. If its gunked up and the sensor isn't fully on a slot the jeep will think you're in 3, or reverse or something else. Happened to me last week. CEL came on and keep wouldn't come outta 3. She's been fine now

And the stalling on bumps sounds also like a ground issue or loose connection at battery.

 

Tell the jeep what? Lol

 

Lol damn auto correct

Colin=cycle
Hear=gear

 

Sorry to be so long responding. I work 14 hour days, not always easy to take the time!!
