TAP Shift Question.

Ok, I am from the old school. There are automatic and manual transmissions.
The 6 speed Auto has paddle shifting? Ok, cool? But doesn't an auto shift it self? How do I shift an auto?
How does this new thing work?

I feel like such a red neck right now.

Thanks for the info Ray!
First post here.

I had a Grand Prix with A4 and Tapshift – a 2005 GXP V8.
And I now drive a 2007 Corvette – with the A6 6L80 trans. and paddle shifters on the steering wheel – as apparently the 2010 Camaro will have.

Assuming ( ? ) that GM holds to the same basic functionality seen in these 2 previous similar implementations, here is how I expect that it will behave in the new Camaro:

When the selector is in “D”, and the paddles are not utilized, the trans behaves like most previous automatics. It will upshift and downshift, using all 6 gears, based on road speed, RPM and throttle position. At WOT, the trans. will upshift at ( or just before ) the engine’s red line.

When slowing, the trans. will downshift through all gears – leaving it in first at a full stop.

The paddles will allow a forced upshift or downshift at any combination of road speed and engine speed that makes sense – and will not result in engine damage. Meaning, for example: a downshift to first gear at 80 will be ignored – to preclude “kaboom”. And an upshift to fifth at 20 MPH will also be ignored.

In both the Grand Prix and the Corvette, each paddle works the same – pull = downshift, push = upshift. BMW automatics with paddles are the reverse. And I believe that a few manufacturers now also have left paddle only for down & right only for up – but only for robotically controlled manuals, not Torque Converter automatics. I believe that no current GM product with paddles and an automatic works any differently than the GP \ GXP & the Corvette.

[[ Edit - Looks like the new CTS-v , with 6L90 ( ? ) will have
"pull left = down
pull right = up" ]]

In this mode ( with the paddles active ) in the Corvette, the trans. will downshift while slowing – but only to second, at a full stop. Not to first. Though the driver may manually select first – either while slowing or while stopped.

Reports indicate that the 2008 Corvette also does a reasonably good job of “throttle blip” \ “rev match on downshift” when commanded with the paddles. My guess in that the new Camaro will also incorporate this feature.

One thing that I have not seen yet ( have not read every word of every thread ) is an reference to, or a picture of a “Sport” mode position for the shift lever in the console. Both the G8 GT and the Corvette ( and the Caddy STS ) have such a position – and this does two things:

Thing one – it activates the paddles. If you push or pull them when in “D”rive, nothing happens.

Thing two – it activates a more aggressive trans. shift map. This includes PAS. [ See quote below. ] And possibly PAL.

In this mode, if you do ** NOT ** touch either Tapshift paddle, at WOT the trans. will upshift quickly & consistently at redline. This is what most people who drag race their Corvettes have found provides the quickest shifts and the best quarter mile times.

HTH.

Looking seriously at the new Camaro . . .

Notes:
In the Corvette, one can start from a dead stop in first gear or second or third. I believe in the G8 GT, only first or second.

Although one cannot actually “skip” a gear on upshifting or downshifting, one can ‘stack’ 2 or 3 shifts, by pressing or pulling

From the Corvette Owners’ Manual:
“SPORT MODE (S): When in SPORT MODE (S), the
transmission will work as an automatic until you use the
Manual Paddle Shift Controls, which activates the
driver manual gear selection. See Manual Paddle Shift
later in this section. While in automatic SPORT
MODE (S), the transmission computer determines when
the vehicle is being driven in a competitive manner
and will select and hold the transmission in lower gears
and have more noticeable upshifts for sportier vehicle
performance.”

From GM, regarding the 2008 6L80:

“All applications feature adaptive shift controls. Several additional features such as grade braking, Performance Algorithm Shifting, and Driver Shift Control are available on some of the applications. Performance Algorithm Shifting (PAS), which detects when the vehicles are being driven in a spirited fashion and remains in its current gear ratio even when the driver lifts a foot off the accelerator pedal. PAS monitors how assertively the driver is using engine output to determine at what engine speed to upshift or downshift. Driver Shift Control, available in the Corvette, STSs and XLRs allows the driver to shift the transmission like a clutchless manual gearbox. Electronic safeguards prevent over-revving should the wrong gear position be accidentally selected.”

Ray you couldnt have explained this any better.

I got a friend with a 2008 Corvette C6 with the Z51 package. All it has is a LS3 with a Tune and a full ZO6 exhaust backed with the 6L80 with paddles. He can come to a stop drop it into "s" mode put on the traction control and floor it !!!!!! The car doesnt wheel hop...... it hooks up better than any car I have ever seen and will hit 100 before you know it. FAST CAR !!!!!!!

If you dont put on traction control its still fast and hell but it wheel hops a little.

Something about that Transmission and "S" mode.

Like he told me get in sit down shut up drop it into "S" mode hit traction control and mash the GAS and hold on..... oh and one last thing.....I hope the manual you're racing against doesnt miss a gear because I wont lol
I'm pretty sure you can down shift all you want, but the car will downshift for you too... if that makes sense. I don't really understand the confusion.
My friend showed me but I cant tell you how he did so but he even told me when you learn how to drive it you can downshift with the Gas. I thought he was BSing me but when he did it and wasnt touching the Shifter/paddles I was like wtf :confused: just something he picked up on his Vette Forum.

When I get the Camaro im taking it to the guy who tuned his Vette.

Knowing that im getting a L99 with the AFM im curious what we will get out of it Numbers wise :confused::confused::confused:

I will make it a forum wide mission to wring every last horsepower and pound foot of torque from our motors......besides I'm getting the L99/A6 too!;) I like to tinker and I'm pretty darn stubborn so it's going to be fun!:D
Do we know for certain they are "paddle shifters"?

My sister has an 08 CTS DI. She (actually I) can put the car into sport mode and shift up and down as necessary. If I come to a complete stop, or close to a complete stop, the car downshifts for you. This is all done from the center console, not the steering wheel. I like this better than paddles.
With automatics beings so advanced and controllable/tuneable at the same time now is there a real advantage with the full control of a manual anymore? To me, an LS3 / stick is not the hottest combo. Am I missing something?
Can anyone comment on how these compare to the AMG in the BMW-M3's? I drove one of those (a 2001 - I think) for a month and absolutely hated the tranny (loved the car otherwise).

For me, unless I was going to be drag-racing the car, I'd still rather have a M6. Unless I'm underestimating the A6, it's just not going to bang gears hard enough for my taste (without spending a good amount of $$ modding it).
If you are a professional amateur, it will make a difference. If you are just getting car that you want to drive, choose which one suits you. I will ALWAYS choose the manual in a sportscar. Changing gears is what I love, not just driving fast by pushing a pedal down. It's like having a pump-action shotgun vs. a semi-automatic. The Semi is faster and easier, but something about pumping that gun makes it more fun.
The automatic transmissions in todays cars are leaps and bounds ahead of their previous models. There are many options when dealing with computer controlled shift algorithms. Proper tuning can taylor fit an A6 tranny to your specific driving needs. Don't disregard the A6 vs. M6 as a formidable opponent in a performance driving scenario.
I doubt it will be anything like the 2001 AutoManual found in some BMW vehicles. A better comparison will most likely be the VW Groups DSG, or Direct Shift Gearbox, which has two clutches, one for upshift, one for down.
Just reviving this thread since the confirmation that steering wheel mounted paddle shifters will be on the A6 Camaros!:roxor:

And **** I'm excited!
LOL yea im excited too...and to know it will be on the V6 A6 as well is awesome...im probably one of the few...but for some reason a 300+hp V6 is way to intriguing to try and play with to get more power out of....cant wait!!
Now I have a question, I've never driven a tapshift but I have driven my friends G6 GT and my grandma's Lincoln MKS both have the manual option on the gear select. Is this gonna work like those or is it going to be more responsive and controllable? I really hate both of those manual overrides that I've tried.

its more controllable I drove a friends 08 C6 automaitc with paddle shifters and it was fun as hell !!!!!!!! nothing like the worthless little switch BMW used to offer with a manual/auto printed on it.
well here is my input on the matter....I drove a BMW E46 M3 SMG which is nothing more than a electrohydrualically actuated manual trans.i can change gear and the thing will bounce off the 7-8,000 redline all dayuntil i either pull a paddle or use the lever which down is upshift and up is for downshift:screwy:.hell i remember comming to a stoplight on a hil i let off the brakes and i immediately started to roll downhill.in a true auto that doesn't tend to happen if at all.i also had to manually upshift a gear in automode to get into the next gear and for whatever reason it would just auto downshift with a nice blip when i hit the brakes in automatic mode which really isn't much of one.

daytona i also agree with you on that,hyundais also have a manual override that spoils the fun in shifting.ALso the VW/AUDI DSG is a MUCH BETTER improvement on the SMG II.the tranny is pretty much flawless.at least the one in a VW R32
After seeing the car in person the tap shift is in a better location than the Vette. IMO its going to be more comfortable using it for the ones who actually sellect an automatic. I griped onto the steeringwheel and loved the feel.
I drove an 08 vette with the tap shift in it just to get an idea about how it felt. My reasoning was the technology existed, and GM is a big fairly smart company so they'd probably re-use a portion of the designs they have already completed (my inner accounant speaking)

Anyway, I like the control in the vette. I was initially slanted towards a manual, but I put my order in for the tap-shift auto.
I'm pretty sure you can down shift all you want, but the car will downshift for you too... if that makes sense. I don't really understand the confusion.
Basically, you can downshift manually, or you can allow the car to do it for you when you brake/stop. You can only manually upshift.

I can't wait to try that out. If a person doesn't like it, leave it in D.
