possible tranny leak
NV3550 on 03 Wrangler Rubicon:

I noticed a small leak coming from the front of the transmission near the oil pan. At first I thought it was the rear main seal. I changed the transmission fluid a couple of days ago and the leak got a little worse but then went back to a small leak. When I say small i mean small..takes about 2 days of sitting to make a couple of drops on the ground. Agreed this isnt a bad leak but I still want to know what it is. I looked up under it between the tranny and oil pan and didnt see anything that looked like a leak. However it is a little wet when touched. The drops form between the plate and the transmission (check the pictures.) At first sight the fluid looks like oil but I use mopar manual transmission fluid which is blackish brown. It doesnt really have a smell either...doesnt smell like motor oil so I'm thinkin it tranny fluid. Anyway look a the pictures and tell me what you think... I'm 80% leaning towards the input shaft seal...

ok with some more research today, It could be the button vent on my tranny. Perhaps I over-filled it a tad and its comin out of it. Does anyone know exactly where the vent it and if i can reach it by removing my shifter boot??
