Bad Tranny seal?

I have a leak under my 1999 4.0L jeep. it has the AX-15 5spd tranny. The front of the tranny is pretty moist and so is the end of the oil pan. I checked engine oil and it seems good. I did both tranny and oil changes about 2 months ago. as far as i know i think its the tranny seal but i may be wrong.

this is after a couple hours of it being parked after driving

Check the back of the valve cover next to the firewall. Its pretty common that its a valve cover leak and it drips down the back of the motor past the Rear Main Seal and onto the tranny and then on to the floor. Seem to occur on both the 4.0L and the 2.5L.

if that's the issue is it something to be worried about? and if so what should be done?

If its a valve cover leaking, its a pretty easy fix. Sometimes you can just retorque the bolts back down. Or just unbolt the valve cover and replace the gasket. Took me about 1 hour to fix my gasket taking my time. I could now probably do it in 30mins.

checked the valve cover as much as i could from the top and bottom of the jeep, seems to be dry. oil seems to just be coming from the bottom. im trying to figure out if its the tranny seal or engine seal

as you can see in these 2 pics, the front of the tranny and rear of oil pan seem to be moist

Looks like rear main seal. If no oil leaking from the valve cover rear left side (visible from the engine bay when standing next to the front left wheel), it's probably the rear main. Plenty of write ups on it here.

im thinking and hoping its that too but since my tranny seems to be wet also im a little skeptical and just want to be reassured i guess lol rather deal with the RMS than having to pull the tranny
