Purchased my 2008 Edge yesterday, put 40 or 50 miles on it and it started dripping oil from the transfer case onto the exhaust right behind the juction of the Y-pipe and the pipe in front of the catalytic converter. After reading some of the similar complaints I wanted to rule out a transmission fluid leak. This morning I took it for a 20 mile cruise (and anyone suspicious of similar oil smoke problems might want to try this) to get the engine nice and not, pulled into my driveway and the smoke started to billow out. Couldn't see the leak at first, so I slid a a piece of cardboard under it to collect any drips. After about 15 minutes a small dot of fluid had dripped on the cardboard. Upon inspection it appeared dark brown, thick, and really stinky. No mistake about it, its gear box oil. Automatic Transmission Fluid (ATF) is red. The 5-20W oil in the engine is really thin, and light brown. So unfortunately, I'm in the same boat as you guys. My guess it the PTU seal is (still) defective. WHY IS THIS STILL A PROBLEM!?!?!
Fix Or Repair Daily - - so far, its true. I had it for one day and it needs to go back into the shop for God knows how long. Quality Ford Tough? BS! Shoulda bought that Rubicon....
