Just wondering if any of the tranny shops on this forum have done any A6 trans build ups and what type of power they can handle/rpm they can handle?

I have a 2006 C6 Corvette A6 with a 3200 vigilanti stall and stock 2.56 gears.
Cartek 3x cam,fast90 intake,vararam,and made 441rwhp and 386rwftlbs.

My best passes are 11.133,11.132,11.147,and 11.155 all at 124-125mph.

I guess i am getting nervous that the trans won`t be able to handle much more and would like to talk with some shops about beefing up this trans.

Thanks for your time.

I've seen 500+ through those trannies and no problems. Ive fixed a few under warranty but don't know of any performance parts for them yet. Dont be worried about it, they are good trannies.

RPM is working on releasing a built A6 as we speak.

Tony B4

Thanks!

So know one other than rpm has anything for the A6 trans?

Whats up tony!!!

I wouldn't worry. The 6L80E's are proving to be beastly transmissions, one of the best GM has ever made if not THE best. From what I've heard, 441rwhp through a 6L80E in a light Corvette ain't nuttin'! These babies aren't 4L60E's. They can take a lot more punishment.

They can't take too much punishment. There are several FI guy's on the Corvette Forum who have gone through several A6's. Some shops limit the amount of power the cars make to help keep the tranny's alive a while. Hopefully RPM will release theirs soon.

Sorry man, but FI guys running 500-550rwhp is SEVERE punishment on a stock tranny FI is brutal on the hard parts of a tranny too because the torque is so high. 500rwhp on a stock trans on a car that comes with 400-430 at the crank stock is huge punishment.

The problem with this unit is that currently the trans controls itself. The transmission control module is apart of the transmission and as far as I know there is absolutely no way to control it or change the parameters of the TCM. The TCM only sends signals to the VCM and the VCM makes changes depending on what the trans does or at least this is the info I have received to the best of my knowledge. Vince

You're the one who said "441rwhp through one of these tranny's aint nuttin". But 500rwhp is SEVERE punishment? LOL

Vince,

Thankks for the replys and it was nice talking with you guys on the phone the other day.

Guys with 450rwhp and less have roasted these A6 trans.

Ive seen stock 4L60's with 450 rwhp last awhile, the 6L80 is a very well designed trans, it has no bands, and no accumulators, every shift has its own pressure control solenoid to control shift firmness. I honestly don't think you will burn this thing up with your power level.

That's what I thought. Sounds like this trans has a lot of potential, hopefully the aftermarket will come around with better tuning software soon.

Vince,

There seems to have been misconceptions about the 6L80 and 90 A6s from day one, based on people guessing about what could and couldn't be done programing wise and also application use wise due to internal controller.

Comments still haven't changed about them in Trans Forum section in last year I've been following them here, while progress on programing them has, but you have to find this out by searching 6L80/6L90 in other sections of forum.

Check out last page of below thread and you'll see what I mean.

hp tuners and efi live both have software to program the 6l80 and 6l90 trans tcm, i just picked up hp tuners and the software/hardware does work for adjusting these trans settings:


GM 6L80e Transmission tuning enhancements
HP Tuners developers have been busy adding additional support for the GM 6-speed transmission (6L80e). Over 450 new parameters have been added to allow very detailed control of the transmission shift pressures and shift feel. These transmissions are extremely complex and that is reflected in the complex nature of the tuning parameters. Definitely a challenge for even the more experienced tuners out there!

Cool that's good to know. Now we just need some more feedback on the software to see how it works. I did hear of a couple people working on it just did not hear that they made it work! Thanks Vince

Absolutely. That's a mild heads and cam package. If these transmissions are crapping out in the 500rwhp-550rwhp mark, then 440rwhp isn't that big of a deal for it. 60 rwhp through a heavy duty automatic is 80-100 bhp. That's a big, big upgrade in power. That's more than the difference between a V6 and a V8 in many cases.
