Transmission leak after multiple axel changes / trans overhaul

Hi All!

I was hoping someone could help me out...fingers crossed!

I've had an on-going issue (3 months) now with my 2010 Ford Transit Connect XLT. I had the passenger side axel replaced and have had endless issues since. After three new axels (after market OEM) and three replacement seals for the transmission (trans output seal) - it's still leaking around the seal area! I've also had the transmission overhauled (new torque converter and deferential plus seals, etc).

Every time I've had the van back the mechanics have stated that they've checked / test driven the vehicle and reported no leaks. I then drive the van for a day or two and then notice transmission fluid weeping around the output seal area.

It's been an exhausting process trying to diagnose the issue. I took the van back to the mechanic who did the trans overhaul today and he said that axel was very hot (it shouldn't be). He also noticed no heat shield around the cat converter area.

Question:
1) should there be a heat shield around the cat converter area?
2) could the excessive heat be causing the output seal to fail?

Mechanic is looking into whether there should be a heat shield, etc.

Appreciate any feedback - would be great to get this fixed! :)

If the seal is leaking after a day or two my first thought would be wrong seal, too much internal pressure or surface problems either on the shaft that goes thru the seal or the housing the seal is pressed into.  By surface problems I mean scratches.  Not certain about heat shield but would expect one around the cat.  

 

 

They should get it right.  Many years ago I had a Ford Taurus transmission die on vacation in Sarasota FL.  The AAMCO place charged us a fortune and was slow!  The local AAMCO shop when we took it in for an adjustment said something like "they charged you a lot" which made me think I was overcharged a bit.  Very last visit to AAMCO.  Transmission needed a rebuild 40,000 miles later when we traded for a GMC Safari.  It's transmission lasted over 200,000 without any issues and only a couple of fluid changes.  People talk about driving the wheels off, my wife did!  The right front ball joint failed twice.  First turning around in a driveway and the second at about 15 MPH.  The wheel just leaned over into the van.

The only thing I can add to what PhotoAl and GBL have already said it this.  If you are taking it to the same guy each time for the repairs, it may be time for a second opinion. Sometimes a fresh set of eyes on a problem can shed great light into the darkness.   I have never paid any attention to the area around the converter on my 2012's to comment on the heat shield.
