Been having vibration from under the car while turning, after extensive research I've determined its most likely the ptu,to make a short story long the transmission shop says 450 for to pull it out. Gets it out sees the oil/ grease coming out the vent says I need a new1 at the tune of 1400 dollars he never opened it up to see what was going on inside. So I take it home open it up no oil to bee seen just a big grease ball,so I clean it out check the gears not a scratch on them no grinding in perfect condition, so I added a drain plug as 2010edge doesn't come with one filled it up with4oz. Of transmission fluid 8oz of 75/140 per the manual calls for 12boz of fluid, had it reinstalled drove 50 miles or so to let transmission fluid clean the rest of the casing draind and refilled with 12 0z ofb75/140 that fluid was black as night will drain again in another 1000 miles sorry theresbno pics wasn't planning on writing a message just wanted to say be careful of your mechanics I almost got charged for a 1400 dollar part I didn't need,bit now I can drain it as much as needed with added drain plug should never be an issue for the remaining life of the car which has 130,000 as of now gl everyone.
