Any TSBs on PTU Leaks for 2011 Edge LTD

CMOS · March 11, 2023

I've been ignoring a PTU leak that prevents me from filling it up for a bit longer than I should have. Have there been any TSBs for the 2011 Ford Edge LTD 3.6L V6? I thought I saw a post a while ago about this being noted for a 2014 or newer but not for a 2011.

Not sure what good a TSB on a 12 year old vehicle would be, other than tell you about the issue and maybe show part numbers and times. I am assuming you are well out of warranty.

I think I misread your question, thinking there might be a recall or something for it. There is a TSB for earlier ones, I don't know if they fixed the issue for 2011 or not.

There is very little fluid in the PTU, so any visible leak can mean half the fluid gone. I had 4 or 5 spots from it blowing the dark nasty fluid out the vent, and looking in the PTU from the fill/sight hole it was pretty far down. I really couldn't get any of the goo out of it, I filled it with new gear lube and drove it for a few thousand miles then sucked it out and refilled it to the sight hole, I don't know if I did it in time or not, but I have 15,000 miles on it since and I don't think I have any odd noises from it.

I don't know if this TSB helps or not, and if it just covers up to 2010 because it came out when the 2010 model year was in production, TSB 09-25-07 (https://www.tsbsearch.com/Ford/09-25-7)

...PTU leak

...any TSBs for the 2011 Ford Edge LTD 3.6L V6?

Which engine: earlier OriginalBlock V6~3.5L~DOHC or later BoredBlock V6~3.7L~DOHC?

Only TSB I'm seen for the notorious PTU is the one linked to above by dabangsta, regarding the RightIntermediate AxleSeal.

Which fluid is leaking from your PTU: 2 different fluids\ leaks possible, Black\Blue 75w140 GearOil or Pink\Red MerconV TransFluid?

Two common PTU leaks are:

* Black\Blue GearOil boiling out of TopVent; goo mess all around PTU, drips down onto hot exhaust wye, makes a sort of sour propane stench.

* Pink\Red TransFluid leaking out of RightIntermediate AxleSeal, again drips down onto hot exhaust wye, makes a relatively sweeter smell + smoke.

If you have the PTU RightAxle TransFluid leak,

the fix is relatively easy with SealKit FordMotorCraft# db5z-7275-e

& a SealRemove+InstallTool like HarborFreight\Pittsburgh# 62601.

Requires removing the RightFrontWheel + RightCVAxle + RightIntermediateAxle(2 bolts) + dropping the ExhaustWye (4 bolts),

then removing the old AxleSeal & installing a new AxleSeal;

use 32mmSocket+Extension to seat Seal+OuterCover, expensive\awkward special tool not needed;

be sure to use SealProtector when inserting RightIntermediateAxle or new seal will leak just like the old one.

Refill the Trans with fresh MerconV; typically 4~5qts will drain when RightIntermediateAxle is removed.

If you have the PTU TopVent GearOil leak,

your PTU likely already has bearing damage due to lack of lube+overheating, will fail sooner than later & need replacing.

For either an existing or new PTU, I recommend flushing+renewing GearOil at least every 33kMiles\4Years,

using a premium HiTempGearOil like AmsOil#75w140.FullSyn.

Also recommend Drilling+Tapping the PTU for a BottomDrain & adding a FumotoDrainValve,

removing the TopVentCap+1WayPlug & adding a VentHose upto under the Hood,

removing the SideFillPlug & replacing with a 90DegreeElbow & adding a FillHose upto under the Hood,

installing a combo VentFIlter+FillCan under the Hood with the above 2 Hoses attached;

this allows much easier PTU GearOil changes.
