Just wondering. I'm not saying it is necessarily bad for the tranny or not because I don't know, but I had always assumed that manually shifting was the way mine got trashed on a previous car. It certainly made a difference on that car if you did it right, and the tranny never griped about it at the time. But what about if you did it at times other than the optimum shift points? It seems at least possible, even if you almost had to be trying to screw it up.
Now for this launching at 3,000 rpms thing. Doesn't work, at least not for me. The reason is that the VX starts powering forward and overriding the brakes before the revs even get that high. Despite having the brake all the way depressed, I can't keep it stationary long enough to get to 3,000 rpms.
