Can anyone tell me if all 2009 4.6 sedans have a mechanical LSD?
Or if Not what to look for to find one with a true Mechanical LSD

I've done some reading and I'm still not clear on which years have the LSD. I know the 09's had a legitimate LSD but at some point they switched them out for a braking based system. I'm not sure what's in my 2010 V8.
