How long has the current automatic (2014) been in use? Seems to be a very tough tranz.

 

2011 in the Mustang but in other heavy duty Fords before that.

 

This auto trans is a very solid trans. I have hundreds and hundreds of runs on an 11 at the strip with zero issues on the trans. And I also have a 3600 stall.

 

The current version of the automatic has been used since the 2013 model year. The automatic before that was different.

 

Wait what? That's not true at all. It's the same 6R80 2011-2014. The 2013-2014 cars just have different shifters.

Only the 2013 and 2014 had the select shift transmission. The prior ones did not. It makes a huge difference driving on the twisties or in hilly terrain. To me, that makes it a different automatic transmission than the 2012 and earlier model years.

But I understand the base gearbox is the same 6R as used in many other Ford models.

 

From the research I've done the 13-14 is different than the 11-12. More performance oriented.

 

The Ford 6R80 automatic has been in use since 2009 in the Ford F-150, Explorer & Expedition, as well as the Lincoln Navigator. It is being used in Australian models such as the Territory and Ranger (since 2011). It has been used in the Mustang since the 2011 model year. 2013 saw the addition of select-shift, but it is still the same transmission internally. It is a very stout transmission that can withstand a lot of power.
