OK....reposting my initial thoughts. And this is qualified in that I can't really go full bore until its broken in.

Pulls stronger everywhere. First gear is NOT a wasted gear. Second gear is really cool - pulls great from a stop, and takes you to 65 easy. Put it in 2nd when you're driving around town, and you dont have to switch gears ever.

3rd is a beast. Not much experience in 4th + in any significant rpm....that'll have to wait. Also, haven't gotten onto the highway yet.

I'll be sure to post about all my traction problems once I get 350 miles on the thing.

BTW - don't let anybody tell you that you don't have to recalibrate your speedo...you do. Either that, or I'm doing 0-60 in 2.5 seconds now.

Tranny is very smooth - feels a bit smoother/tighter than stock.

My DRAFT bottom line is that I think it was a VERY good mod, and would do it again in a heartbeat. Huge SOTP gains..and more to come in 300 miles.

I just put a 3:42 complete rear diff in place of my 2:73 and the speedo is dead on. Is this only a problem with the A6 gear swap? I also did the same swap in my C5 and that speedo was perfect too.

 

Autos need the programing adjustment manuals do not.

 

Thank you for the business and it's great to hear you're pleased with our product.

The 2006-2007 A6-equipped vehicles are the *only* cars that require custom ECM/TCM re-calibration to correct *BOTH* the speedometer *AND* to enhance shift point strategies, due to the fact that these models do not receive their VSS input from the differential ring gear as all other previous automatic-equipped models did, but rather from a reluctor ring within the transmission itself, on the output shaft. Previous auto models require PCM calibration to correct shifting strategies only, as the VSS input for these vehicles are taken directly from the differential ring gear and speedometer calibration is not altered with a gear change.

Wow! Thats an awesome helpful response, wish they all were like that.Thanks!

 

Thanks for the info. I'm trying to get to the tuner today.....but my car was tuned with LS2Edit, and we cant do shift points yet. Only speedo. Hopefully the shift points will come soon.

I didnt get any specific do's and don'ts on the break-in. Can you please post what I'm supposed to do for the break in period? I'd appreciate it.

 

You didn't??

You differential was shipped with a full documentation packett physically tie strapped to the unit that your installing dealer should have given you. The cover sheet that's stapled to this packett states right on the front in huge bold letters, (para-phrased) "Installer Please Read- Customer Must Read and Sign Their Warranty Paperwork To Activate Their Warranty Coverage". We know they have to see it when they open the wooden crate it's shipped in, because the tire strap that secures the packett to the differential must be physically cut off to remove the packett from the differential case itself to even install the unit into the car. We do this so we don't get the, "I didn't see anything in the box" excuse...

It explains break-in procedures, filling instructions, lubricant type/oil change interval recommendations and basic care/maintainance paperwork for the unit. It also contains your warranty documentation, for which one copy you'll need to sign/date to send back to us to activate your warranty.

It's very important that you get this paperwork and we're adament with our dealers that they *must* forward you this packett of information for your own benefit, otherwise they will have effectively dis-armed you of your warranty. Some dealers, for whatever reason, decide that this information is not important and they throwit in the trash, negleting to give their customers the proper information they need. Some follow our instructions, some still refuse....

You need to tell your installer to give you this ASAP- it's very important!

BTW- We use HPT Calibration Tools here for the C6 Corvette platform currently and it allows proper ECM/TCM calibration for these gears or any other modifications one wishes to do.

Mark,The folder thats in your car has all the info on break in and warrentys.

 

There you go, thanks Kevin.

if you dont mind what was the cost of the change,im thinking of doing the same,where you able to use the 273 as a core. thanks

 

Hi greentank , you REALLY need to get the HP tune for your shift points and overall A6 driving fun . I also had an LS Edit tune before my cam was installed ,but the HP tuning made a very noticeable difference . DTE is within driving range for you , so consider that as an option . BTW , my 3.15 gears came with the warning ... " Break in is 350 miles , please try to refrain from blowing the doors off unsuspecting Mustangs until then ." Enjoy the gears , I know what you mean about 1st and 2nd . Best wishes , Larry

 

yep...my bad. I thought it was just the "what not to do EVER" list, not the break in list. heh.

 

So Green,..how much did it cost You for parts and labor?
I have an A6 and am thinking about this!
DTE is an AWESOME Compamy.
Also,question for DTE,will my local tuner be able to "calibrate" my "shift points" "and speedo"?

 

We don't know the level of proficiency of your chosen tuner, so we can't answer that question. However, if they have invested in the latest HPT calibration tools that are available to properly calibrate these newest C6 Corvettes as we have, then they'll have one area covered already.

 

I did stage 2 with all the options. Parts were around $2500 plus shipping, labor was around 4 hours.

I'm enjoying the gears as much as I can....I'm very close to breakin. I'm showing almost 350 miles on my ODO, but that's not really correct, since the car is recording more miles than I've actually driven (my gas mileage is awesome though....42mpg average highway. lol)

In another day or two, I should have enough miles to start pushing it a little....cant wait. Right now, with medium throttle, 3k to 4.5k rpm pulls like my old 5k-6k rpm.....

Anybody have a nice set of 305 rear tires for sale?????
