transmission fluid leak
hi guys! another problem here, when checked underneath my JKUR 2013 last night, found one more leak, transmission fluid. the fluid is over the back part of the transmission from the top to the bottom. I think it is not the transmission oil pan otherwise there shouldnt be any fluid at the top part. any idea or suggestion on how to check the leak?
As my jeep was parked for the whole day and there was no fluid on the floor so I assumed it is some kind of seepage?
Any help will be great!
don't know why but the uploading the picture always stop at 90%, I will put the pics on when I figure it out.

It's not apparent on my computer what color the fluid is.
Assuming it's red ATF+4...Has anyone recently checked the fluid level, and added some fluid? That looks more than a leak. It could be getting pumped out of the dipstick/filler tube, or out of the transmission vent.
So, check the fluid level with the transmission warmed up, engine idling, in Neutral or Park.
If that's OK, clean all the residue off with brake cleaner, cleaning as high as you can get on the transmission. Keep an eye on it to see if you can determine the source.

Thank you Ronjenx, just got another reply from wranglerforum, it is the engine oil, from the oil filter adaptor assembly. that's why no oil from the engine oil pan.

The parts to fix are about 300$ if you get from a dealer. With the number of those that fail I went dealership with parts for the 2yr warranty in the event it fails again. Total wrench time to swap out the cooler filter housing is about 4 hours with a couple beers. Not terribly difficult but lots of little steps

See post #3. OP had a leak at the oil cooler. Likely a stupid o-ring, could be a crack in the filter housing. Regardless, it means the entire intake comes off the top of the engine just to get to the parts. If you go to a dealer you could be looking at $5-800. If you are handing and can do the work at home it's a few hours time in the garage.
