CMOS Posted June 18, 2021 Report Share Posted June 18, 2021 So in getting an oil change on my 100K mile 2011 Edge Limited AWD I was informed that the transfer case output shaft was leaking gear oil, and the transmission is leaking ATF. I had to top both up as the oil change place can't wrench a transmission. Would these problems be related to the PTU issues I am seeing all over this board from literally 2008 to 2016 or something? I more likely than not have shavings in the transfer case but the car has not had any issues driving. (Technician said it has probably been there for quite a while).

DILLARD000 Posted June 20, 2021 Report Share Posted June 20, 2021 (edited) I'd confirm what OilChange Tech said; best put Edge on jack stands then crawl under & inspect yourself. PTU=TransferCase could be venting GearOil out top & that's spilling down over the case & rear output shaft? How many miles on the vehicle & has the PTU GearOil ever been changed? Does your PTU have just a 1/2" FillBung, or does it also have a smaller DrainBung? If only a 1/2"FillBung, then recommend Drilling+Tapping the PTU case bottom & installing a Drain.

enigma-2 Posted June 25, 2021 Report Share Posted June 25, 2021 I've had bot seals replaced under extended warranty on my 09 MKX. About year and a half after I had the complete PTU replaced (seal leaks in the PTU cook the remaining lube killing the internals). Quote Link to comment Share on other sites More sharing options...
