2017 Grand Sport torque converter replacement complete (with pics)

When looking up 24279495, the description states that it replaces 24264542 and 24273061. Then looking up the lastest part that was installed on my car, 24280631 I see that it replaced 24279495. That means there have been 4 different "versions" of the torque converter since the A8 was released.
767guy, I don't have my paperwork yet but the pics I posted at the start of this thread has the info you are asking about. My 2017 was built on 8/12/16 with converter 24279495 and it was replaced on 1/6/17 with 24280631 which I'm assuming is the latest version.

I'm glad they got you fixed up and treated you well. Particularly so, since you are first time Corvette buyer.
Since you are first time Corvette buyer, please hear me when I tell you the Corvette of recent vintages have been well-built and robust. It sucks to see somebody have issues with a new one. Sucks even more when that person is a first time buyer. Don't let this shake your confidence.
Enjoy your Corvette. Put all this behind you and go have some fun.

Thank you for the update!
For those of us with the A8, who bought from Stingray, or within driving distance, this is great news. Knowing the problem can be handled quickly, and effectively by a competent dealership is very settling.

It is encouraging.
If I had an A8, which was still performing normally, I'd still be contacting every Chevrolet dealership within a several hundred mile radius, speaking to the Service Manager, and asking for stats on the number of TC/Transmission replacements they have performed on the A8. The service department that reported the highest number would be the place my car would go for repair.

767guy, I would say yes. The transmissions are the same whether they are installed in a C7 base, Z51, Grand Sport, or Z06. I think the only thing that would differentiate would be when the car was built or the timing of when it was replaced.
If you are going to get the TC replaced again, I would insist on the part# 24280631 I listed. Unless of course it winds up getting updated again.

Congrats to the OP and Kudos to Stingray Chevrolet. My repair took over 30 days but also included a fuel pump replacement.

I'm glad it was repaired and is better than new now! I'm even more impressed with the positive way in which you handled a negative situation. We need more of this and less of the chest thumping and keyboard pounding. May you have thousands and thousands of trouble free miles ahead!

OP, would you be able to look at your paper work from Stingray Chevrolet and post the part # of the new TC.
The paperwork should show the old part # being returned as a core and then show the part # of the new TC installed.
Glad your car got fixes and I think you had a really good dealership that knows what they are doing on your side.
In advance, Thanks.

They probably are. The OP's car most likely was built before this new revision.
It would be interesting to find out what exactly was changed (materials, supplier, design) but I doubt GM will be forthcoming with any info unless they absolutely have to. Even Tadge's answer about this issue was pretty cagey.

lakemg,
When I take it out on the interstate @ 70 in V4 mode, my tachometer is rock solid. No fluctuations whatsoever. No shudder, no hiccups. I swear if it wasn't for the dash telling me the car is in V4 mode, I can't tell.
Something else I wanted to mention is that the car is far more reluctant to jump into V4 mode than before. On the way home, I would steady cruise and it would stay in V8 mode during times when it should have been in V4 and this is at normal operating temps.
Either they reflashed something or the computers were wiped and it's in relearning mode. Guess I need to start driving more aggressively.
The service manager did say that I would be getting mailed a detailed printout of everything that was done to the car. Not sure why she wouldn't just give it to me right then and there but she mentioned something about them having to close out the ticket first. Since I'm impatient, maybe someone with access to GM GlobalConnect would like to help out if I PM'd them my VIN?

What exactly is failing inside the defective torque converters? Seals, lock-up clutch, bearings, something else?
Everything in the TC is used in both modes, so why does the failure show up in V4 mode instead of all the time?

I read somewhere around here that the Z06 version of the A8 is "beefed up" and is a different P/N. However, I've seen accounts of TC problems with them too, but there's much less discussion about this issue in that section of the forum.

If you have nothing better to do than trash the car, at least keep your "facts" straight.
Less than 20 posts you voted in the poll stated that your '17 had a bad TC and transmission. Yeah.....you have great credibility.

Why do you reply to my positive comment about the way a reasonable man handled a problem with more chest thumping and keyboard pounding?
I wonder how long it will be before your latest incarnation as "CorvettePride" will be banned...

Not sure if this is clarifying this issue as to which TC is the latest version, I offer this info based upon my experience. My 2015 base has a build date of 2/3/2015 and had a TC removed on 11/18/2016 having part #24279495 which was returned to GM as a core and was replaced with a TC of the same part number. This same part# is listed as a replacement for TC part #s 24273061 and 24264542 according to Google. Therefore, I can only assume that since it was installed in a latter model Corvette, part # 24280631 might be GM's latest version. My apologies if this muddies the issue.
Regards,
Ralph
