Questions on 2006 to 2009 A/T compatibility.


Recommended Posts

Something blew out on the transmission on my 2006 Outback, and I am looking to replace the entire transmission.

 

I am hearing mixed stories about whether a 2008 / 2009 A/T will work in a 2006.

 

I have the four speed sport shift version.

 

Gear ratios on the 2006 look to be the same as 2008, so I don't see why a 08 or 09 A/T would not work in a 06.

 

I do suspect the wiring harnesses may be different, as the part number on the 2006/2007 A/T is: 3100AG560 and 2008 has both 3100AH310 or 3100AH350.

 

Has anyone installed a 2008 or 2009 A/T into a 2006 / 2007 ? If so, what if anything needs to be swapped ?

 

Any help will be much appreciated.

legacypic.uk has a list of all the transmission codes and ratios. I don't know if that helps.

 

For the 5EAT, 2005-2007 has a limited slip rear differential with no VDC, and 2008-2009 has an open rear diff with VDC.

 

I don't think you'd have to worry about that for the 4EAT but they did get VDC standard for 2009 so it's worth looking at that.
