Rear main seal possibly, fairly common failure. We've had 2 fail (2013 & 2014) both replaced under regular warranty. Do not believe they would qualify for power train warranty but your dealer can answer that.
I posted about this in another thread recently - it could be your oil filter housing as well. Take the engine cover off and use a flashlight to see if you can see oil in the valley of the engine. Shine it down around the base of where you place the oil filter. If you see oil down there, the housing is bad.
A bad oil filter housing can appear similar to bad rear main seal on the pentastar. There's a hole on top of the block that will allow the oil collecting in the valley to drain behind the flywheel and drop out exactly where you're seeing it. The wire shows where the hole is. From the top, you can see all the oil in the valley - it can hold quite a bit.
Lot of threads here in JK forum regarding the oil cooler or the associated o-rings failing, causing the engine valley to fill with oil that then runs down the back of the engine and down the bell housing of the trans.... shine a flashlight into the valley beside the oil filter cap to look for oil - or take a chopstick - it is slender and rigid enough to go down smoothly into the valley - and see if it comes back up with oil on it...seems to be a common occurrence on JK/JKU’s
