#908 of 917 Re: C6 rear diff noise [Bolivar]
Jul 15, 2008 (8:09 pm)
I previously mentioned that my '07 C6 with 4.5K miles had developed a noise in the rear while driving slowly and making tight turns. Apparently, Vettes are known for noisey rear differentials.
I had lube service done today and while at the dealer they replaced the rear differential fluid with something "new" from GM" and described in a technical service bulletin ( listed on Edmunds ). The service writer seemed familiar with the problem but was typically hesitant to give "too many" details.
This fixed the problem and the car now drives like it did when it was new. I hope this new lubricant continues to solve the "problem".
Thanks for the assistance in describing the problem and the "fix".

2008 Coupe, the left rear wheel well does not fit well to the body, you can actually slide your fingers between the edge of the wheel well black liner and the exterior quarter panel. The dealer says there is no correction. Any suggestions?

I would immediately take it to another Dealer - one that has
a Corvette Tech & a good reputation for customer
Not trying to be a wise a$$ - there are lots of Chevy Dealers to choose from...

#911 of 917 2005 Dead battery Syndrome
Aug 30, 2008 (9:05 am)
2005 6-speed Z51 has the dreaded dead battery syndrome. It is my understanding that some component needs to be reflashed. My dealer is less than helpful so could someone educate me on the particulars and if possible a TSB# or other info so I can educate the dealer and get this done. Any other suggestions from 2005 owners would be appreciated. The vehicle only has 1621 miles. Thanks!!!

DBS is directly related to the requirement that all 2005 manual transmission cars must be placed in reverse for a proper shutdown of the electronics. Assuming that you always shift to reverse when shutting down, DBS refers to an unexplained battery drain on properly shut down cars, and typically occurs within 48 hours of the car being turned off.
If this is the cause of your problems, rather than just a weak battery, GM has issued a TSB that calls for a reflash of the BCM, or Body Control Module. This reflash has been completely successful in addressing the problem. I don't have the TSB # handy, but any dealer should be able to find it in their computer database.

You can go to www.alldatadiy.com and click on technical service bulletins and recalls, enter your car and see all tsb's for your car.

And, with a 3-4 year old battery, it might just be time for a new battery. The battery in these things is small, only 550 or so CCA, which the cheapest battery at Walmart can beat, and the car has a lot of electronics in it. For the low milage you stated, you cannot be driving the car regularly enough to recharge a battery.
But given all of the above, yes, there is a TSB on reflashing the logic in one of the car's computers. This should be done no matter what.
It's a shame if your dealer is not really wanting to help you here. This is a very well known problem, and a dealership servicing any amount of 2005 manual cars should know about this. And even if the car is out of warranty, the dealer should be willing to do this for your car.

Sorry to revive this old thread. Same car. I've had it to the dealer for this problem several times and they know nothing about this problem with this model, but they said they reflashed the computer. It is possible that they only did the DCM, not the BCM. Is there any way to determine what has been done, or any way to reflash this myself. Is there any aftermarket equipment that would allow me to do this myself?

I have called two dealers so far and they can't seem to find it. They did find TSB# 070603001B for re-flash of the Remote Control Door Lock Receiver (RCDLR).
I am assuming this is a different issue. He said it was related to 2005 - 2007 models. Does anyone have the TSB # for the 2005 - 6 speed DBS problem?

If a dealer works on any number of Corvettes at all, the service people should know about the 2005 manual tranny dead battery problem - and that there is a procedure to solve it.
Find a more knowledgable dealer.
Are you sure it's just not a bad battery? These batteries are small. If you let your car sit without running for several weeks at a time, the batteries on most of them will run down. And if a battery has been killed once, it will never recover to its full power.
