I am trying to find out if there is a limited slip differential available for the Aisin manual transmission in the 2011 Fusion. Ford offers the Torsen differential for the MTX-75 and Getrag transmission used in Focus applications, but I don't see anything for the Fusion. The Torsen is nice because there is no fuel mileage penalty and they are extremely reliable.
Reason I ask is I am self employed sales rep, driving 55,000 miles/yr, much of it in snow country and I have a long steep driveway. I would prefer not to be dragging the AWD system on all those highway miles. I currently have a diesel Jetta ('06 with 280,000 miles). I would expect to get the same service out of the Fusion. I have a Focus with 200,000 that has been pretty much trouble free, so its definitely possible.
