Thanks Dan,
This piece has completely broken off of the Transmission now, seems to be a defect in the trans that began with just cracking and then grew into a chunk surrounding the bolt hole that broke away from the Trans, and I have a lot of vibration when driving so I'm wondering how to fix this..
There's an identical threaded hole on the Trans that's about 1.5 inches away from the broken hole is,
do you know why that's there? - and is there an extended roll protector (perhaps for another model like the Escape?) that would reach that threaded hole? I'm baffled on how to re-secure it..
Any suggestions?
The Forward hole is left over form older Fusions using the 6F35 transmissions( up to 2012 and I have a 2010 AWD) which had a two bolt Roll Restricting bracket, not the L shaped bracket shown(Two bolts through the L shape into the back of the transmission) used from 2013 and up! Up to 2012 also had a different PTU and a different roll restrict anchor on the Engine cradle!
That Break looks fresh(Little to no accumulated Road debris in the break and the bolt looks like it was loose but that could be from the lost thread and initial torque)!
From the bubbled nature around the back side of the mount I would venture a guess that the Vibration(if it is Fast Drive line Vibration and not slow wheel vibration) you say you are experiencing may have had something to do with it as it looks to me like a metal fatigue crack that has progress very quickly!
It also looks like there is crack forming around the unused bolt hole so any engineering you do there is probably only going to prolong the eventual transmission replacement!
Being as this looks like an AWD Fusion I would be suspicious of rear drive shaft vibration and I would also be looking for seal leaks from the PTU and the Rear differential input pinion seal as well as loose Drive shaft Ujoints and/or steady bearings!(PTU=Power Transfer unit or Rear Drive transfer case)! Drive shaft vibration problems very often show up first as related seal leaks!
Also these PT units have a very high failure rate after about 100,000 KM if the oil is not changed regularly(They have very little oil in them and they can get very hot)( I just replaced one in the aforementioned 2010 AWD at 124,000KM and the oil in it was black sludge)!
From your Images the 2013 PTU at least has a drain plug! The older PTU had to be removed in order to change the oil!
Unfortunately the only right way to repair that break is to replace the transmission after finding the reason for the vibration!
Don't Know for sure but after 55 years in the business, my feeling is something is concentrating vibration stress around those two holes and your remark about vibration is what jumped right out at me!
