Likewise, he stressed that the optional six-speed Hydra-Matic 6L90 automatic gearbox is “not for poseurs who don't know how to shift.” As a general rule, hard-core enthusiasts will choose the six-speed Tremec manual transmission, but at least the auto 'box is built for performance, with three different driving modes including a manual setting that only shifts when a driver commands. Automatic upshifts will not occur even at redline, and Oppenheiser promised that it will select and hold the appropriate low gear into corners to match the manual-equipped ZL1's performance.

“Contrary to what we could have done [by taking the easy way out with a simple, off-the-shelf transmission], the automatic is not a compromise,” he said. “We spent a lot of time working on it for the track.”

It certainly sounds like even the auto is track ready! Up and Down the gear range! Holy Sheet..... I forgot to make the bed before my wife gets home...... BRB


I also read somewhere that in driving mode 1 & 2 the auto starts out in 2nd. Anybody else know about that?
"The ZL1’s automatic is a Hydra-Matic 6L90 six-speed with additional clutch plates, a strengthened output shaft, and the extra planetary pinion gears needed to ensure survival in this trying assignment. The transmission is programmed with three operating modes. The normal Drive mode uses second-gear starts, quick upshifts in the interests of fuel economy, and temporary manual operation when a down-shift button is tapped or the lever is moved. The Sport mode ups the ante with first-gear starts, more aggressive gear changes, and shifts delayed to higher rpm. In Manual mode, there are no shifts until the driver commands one; gear changes are as fast as possible for maximum acceleration."
