tin-man,
I saw this and am forced to chime in:
I'm not sure what this means. I have a C-6 in my car (built by Carl Rossler, Girard, OH) and can tell you from experience that others warned about this before I got my car.
Here's what my experience says about that:
It is speculation based on ignorance, not experience!
I've run my car in autocross, at Roebling Road, Sebring and Daytona to name a few places. I put it in drive and two-foot (one on the brake, one on the gas) and it is heavenly! Others have driven this car on the track and remarked how easy it is to drive, and can go quickly and smoothly.
Those who say "don't do anything sudden" have the correct idea. Concentrate on being smooth and fast will eventually happen.
The most important thing I've learned about the automatic is that it is vital to have the correct torque converter and a really effective trans cooler. I learned this after boiling the fluid out and melting the cooler's fan the first time I ran 30 minute sessions at Sebring. I found a torque converter guy in Deland FL (FTI) who recommended a 9-1/2" converter and a 1600 rpm stall speed, who also assures there is maximum
oil flow through the converter. Apparently if
oil flow isn't sufficient, not enough cooling can occur in the cooler itself. All I can tell you is that before the converter, trans temps went over 320F in the trans pan, and afterward never exceeded 240F.
So enjoy your auto - it wouldn't surprise me to see more dedicated race cars switching to automatics - oh, wait, some already have!
