FWIW, the "manumatic" feature on my 5-spd auto G35 is totally worthless. It does an incredibly bad impersonation of a manual, so bad that I've completely given up on using it except for the most special of circumstances. Even then, the ECU routinely overrides the driver's manual choice, making attempts to use it even more frustrating. Still and all, it's a great car and I love driving it, but with the understanding that I've surrendered to the computer at least with respect to shifting. Hey, it would take a really bad trans to spoil almost 300 hp going through the rear wheels. The ECU makes the right choices 90% of the time, but still, that manual fun factor is just not there. My routine traffic jams are much less of a PITA though. Ah, compromises. . .
