My 13 5.0 was an auto. I tried to convince (lie to) myself that it was o.k. but I just never warmed up to that tranny. I think that though Ford's present automatic is improved over the older ones, it still sucks life out of the car. I am talking about torque. My 5.0 never set me back in the seat like I thought a 420 horse car should. I don't believe for a minute that the one I had was making 390 lb/ft of torque. Sure didn't feel like it. So, I sold the car. On the flip side, both past manual mustangs I had, pulled hard and I loved them both. If I ever get another mustang (and based on my history and love for them I probably will) it will be manual or bust for me.
