My father-in-law has a 2007 with paddle shifters. He experiences the lag on upshift that has been reported as fixed on the 2008. (I'm have an 02 Z06 6 speed manual so I can't relate) Anyway, I did a search and can't find this.

Has anyone tried to get the dealer to program the 2007 paddle shift tranny with the 2008 program ?

Thaks,

Well, there's tons of talk about lag on this forum but it's from a few unrelated issues.

My quick answer is, no dealer is going to load an 08 program into an 07 Corvette. There is no good reason for a dealer to even attempt it and it's probably not even possible using their hardware. Heck, dealers don't even want to update your software with one written FOR your car unless you beg them and prove you're having an issue. GM's stance is "Don't fix it if it aint COMPLETELY broke".

Thanks.......... funny thing is the tech at Champion Chevrolet here in the desert suggested he take it to an aftermarket shop.

And then the next time it's in the dealer for service they'll scream that it's been modded and void the warranty.

i have an 07 C6 A6 and i had a similar problem, you're right the dealer did not know how or did not want to. so i spent the time and money and took it to B P Products in Dania, Fl he not only fixed the shifting but also unleashed 45 hp. the car now shifts a lot firmer and under wot operations when shifting to 2nd breaks the tires loose. the paddle shifter works great in upshift or downshift.
Ernie at B P products did a great job, give him a call.

I had RevXtreme do their Tranny flash on my 07 A6, made a night and day difference.

About a week later had to take my car to the shop for the p.i.t.a key fob/dead battery problem, and the three times it was in there, they had the scan tool plugged in and never mentioned anything about the new tune. i get lucky tho, i always have the same guy working on my car, and he loves the vettes.

Do they make a Hypertech type gizmo to program the Vette?
I have a $300 Hypertech off of eBay that attaches by cable under the steering wheel of my '02 Suburban, and one thing it does is quicken and firm up the automatic shifting.

I haven't heard good evidence yet that the 08 shifting was noticeably faster than the 07. Some claim it is a split second faster but it's still lags. For certain it will not compare with any good A6 tune.

Yes, a Predator programmer (make sure you get the correct one for your year). I will be putting mine up for sale any day now, complete with cables and power supply for an 06-07. I bought HPtuners so don't need it anymore.

On the upshift there is not much if any difference between the 06/07 and the 08 6spAT, however on the downshift the 08 is much improved with revmatching being the big improvement and tighter downshift.

Only a good custom tune can fix the A6 lag, I'm not aware of any of the handhelds with this ability. We do the A6 tune alone for $99 while you wait or a complete dyno tune for $349 special right now

To my knowledge (unless something has been released recently), Predator tuners do not have the capability to flash the transmission on our 'Vettes; it is something they have been working on for a very long time but as of yet there have been no releases. I too am anxiously awaiting this update.

HOONOSE only asked if handhelds such as the Hypertech were available... The answer is yes, and I have one for sale ( http://forums.corvetteforum.com/show....php?t=1998533 ). I agree, it will be a very nice update when they add trans tuning.

Letting RevExtreme tune your car is an even better option for those nearby. Tracy knows his sh*t.

BTW, Tracy, will you be going to the Corvette Challenge National in Richmond in May? Will/can you tune there? I can't tell you how cool that would be.

Gotcha.....

'can't wait for the folks over at Predator to release the 'trans tune' upgrade...

We are scheduled to be there & racing, but not sure on the tuning. Let me see what we can do.....I'm sure the demand for the "Bracket Tune" would be high.

C5pilot

Bracket Tune??? Oh, now you have my complete attention. Is this something I need to call you about or can you explain it here?

And yet, the C6 Brochure for my 2007 states:

"Squeeze either of the two steering wheel-mounted paddles towards you and the available six-speed automatic transmission shifts down
at lightning speed, the throttle adjusting automatically with each downshift for smooth transitions. "

And it does not...
(( sigh ))

Only wanting my 2007 to do what Chevy said it would do...

Of course all of us being bracket racers Chris has worked the tune for max consistancy (do a search on Bracket Tune to see a set of time slips) . It is not the max power tune, but being bracket races concistancy is the key. If you have HP Tuners Chris can email you the tune for $99.

I have HPtuners and you can really firm up the shifts by removing TM during the shifts. If anything the shifts may be too firm for the street. However, I do not see any settings that allows you to remove the lag of when you hit the paddle and the tranny finally shifts.

It's in there
