Tranny shifts super fast and very firm. Uses 6 speeds in the quarter mile and when you back off and brake, it does rev matching downshifts. It is the best transmission I ever experienced.
The 5.0 sounds good and the videos do not really do it justice. They lack the low end torque of the turbo V6s though. A 3.5 SHO or even my 3.0 Continental has more punch below 3000 rpm. The 5.0 is at its best between 5000 and 7500 rpm.
