After swapping from a VE II Calais V L77 to a VFII Calais V LS3, I have always liked the way the VF gearbox downshifts (manually actuated by me) whilst slowing down to stop at a set of lights for example. The pops and crackles of the exhaust sound great, though it is the way it shifts down that makes it feel so different (....sportier) than the VE, which had that characteristic lurch as the revs soared when the box downshifted. The VF feels far more fluid and intuitive. It's no GM 10 speed or tremmec dual clutch, though not bad for what is essentially a comfort oriented torque converter auto box. I know Holden tuned the box specifically for the LS3 though does anyone have further info on this? Why does it feel so much better in the VF when manually downshifting?
