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

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.

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....

BINGO!!! A stall will absolutely make ZL1 a beast. Throw some DRs on it, and it's going to humble many other cars. I'm curious to see if a lot of the calibrations are similar to what tuners have already been doing for some time.

Yet more money to spend to get the tapshift to respond faster.

That video looks great!

I'm currently driving a Lexus isF, and the auto trans in this car is just fantastic!
It is an 8sp auto and the shifts are quick...very quick and I doubt any human would be able to shift much faster. In fact it's better to just let it shift on it's own.
And it downshifts very nicely...it will even blip on a downshift.

I hope the auto trans in the ZL1 is the same...it would make people think twice about getting a manual if the car will be a DD.

I know some people will not agree with me, so my only advice would be to stop at your nearest Lexus dealership and test drive the isF and see for your self.

I am in no way pushing the isF, just using it as a bench mark in today's automatic transmission technology.

With that said, the ZL1 will spank the isF all day long with whatever tranny is in it!

For those wanting this retrofit for the 2010-2012 V8 and V6 Camaros, its not the same transmission. That transmission is the 6L80. The one in the ZL1 is the 6L90, which is based on the 6L80, but a different transmission with different software. They may be able to re-design some pieces in the 6L80 and then change the software. Probably not worth it to GM. On the flipside, they could put the 6L90 in those cars starting in 2013, but again, what's the cost and is it worth it.
