but I am sure it's more comfty than a manual. just can't beat a manual for fun though!

I have a 2SS now, and if u use competetive performance mode and trac off it will surprise you, and with the new tranny improvements,from what i hear [ were really gonna like this auto ] should be very exciting....I can't wait to get my hands on it sitting beside a M..Turd. Ops did I say that..

Sorry but i still believe that the auto is only going to be quicker for the average driver !I bet a good driver with a 6 spped is still going to be quicker

Revo1 · 02-24-2012, 01:00 AM

I'd like to see a firmware update for the '10s. Shift response is my only beef with the current setup...

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."

Maybe....but the number of people who can really shift is dwarfed by the number who think they can.

See it at the track all the time. Some guy in a Z06 will walk around with his chest out blabbing about how he owns a 10 sec car. Then go rip off a few mid 12's,park it,and stand there scratching his head wondering what's wrong with his car.

I'd like to see the best manual driver out shift that besides the fact you never disengage the drivetrain by putting in the clutch

hognutz · 02-24-2012, 10:01 AM

I have always felt a properly built auto is better for the quarter mile. I have yet to drive one yet that I like as well on a road course.

That upshift response in the video looked good. Would like to see a vid on the track with up and downshifts. That is where the feel awkward to me.

CFD · 02-24-2012, 10:20 AM

I have driven many manuals and here are my thoughts, putting aside the "fun factor" as that is a matter of personal preference, when driving an auto, especially with tap shift and the two hands and feet god gave you, you have the ultimate control. You can brake, accelerate ,shift and steer simotaneously without ever disengaging your drivetrain, this disengaging and re-ingaging your drivetrain is what gives the undesireable charecteristics when shifting in corners. These charecteristics although not completely eliminated, are drastically reduced allowing precise shifting and control.

Have you checked out the Jannetty tune? It does wonders for shift response (plus a whole lot more)

I think this is a quote from a source from some time ago before more specific details have been revealed.. or designs fully finalized.. kind of like when we just knew the car would have >550 HP.... do you have your source and time by any chance? I would think in Sport Mode in D, you will have 1st gear.

The source was from one of the "sticky" threads above. I'll look later. The Camaro Manual on page 9-20 Driving and Operating mentions 2nd gear starts only in the "D" mode. After the first start in that mode.

Cool video, my 2011 SS rental was a bit slow on the tap shift but this seems to be far more improved.

I wonder how the ZL1 will do when someone installs a torque converter in it for the 1st time... those CTS-V guys are saying the all get AT least a .5 decrease in there 1/4 mile times. When I do order mine, I am going with the auto for sure!

a smaller pulley change will happen as well, har har har....
