Agreed, Delco is a solid brand, but the c8s have stuff going on. Didn't they have some software fix for some module that was draining the batteries just recently. Also, it seems many had issues during or right after an update. Which is why I wont do them over the air. I'll let them do it when I take it in for service.

Yes, there's an update available that can be completed by the dealer at no charge.
We digress but can you buy those individual sensor parts?

My observation re the DCT "failures" is a bit different than Chicken Little it's terrible.
The positives:
Folks have installed turbos and produced over 1000 hp with minor changes, like cultch disks and axles.
Even the ZR1 has minor DCT charges.
Dealers have been told my GM Service to just perform a Flush when given the CEL code #. For many that solved the issue.
The Tech that worked on >50 DCTs said there are so many sensors, like 3 pressure sensors, many position sensors so it will not switch clutches gears unless every Shift Fork is where it should be etc. He showed over 100 CELs and said he only had 2 the same.
IMO the reason Dealers replace the Transmission could be for one position sensor failure. Dealer Techs are not to open the transmission to find and perhaps fix an inexpensive sensor, solenoid etc. From my experience with Automotive Vendor Supplier Contracts, Tremec is on the hook to replace the Trans during GM's Warranty. And they have probably to reimburse GM a fixed fee they pay Dealers to replace the DCT.
When Warranty is up, Trans repair shops will be fixing. Probably like a standard Trans there will be few issues with shift folks, Sychros, bearings, gears. The control components, sensors, solenoids hydraulic actuators will not be that costly to replace.
I still wonder what Tremec is doing with the retuned transmission.s They are not just becoming Boat anchors. Will they be repaired sold as replacements? Is a Trans replaced with only few miles, repaired being put back in service?
Yep the DCT is essentially two 4 speed standard transmissions with hydraulic actuators moving the shift folks instead of a lever. It has many sensors, solenoids that can fail or clog with clutch debris.
If you can't buy them, it's unfixable at this point.
2024 died after 2 weeks of not driving. Tried to jump and the lights flickered, the horn beeped and the drivers window went down. Now completely dead, won't jump, put it on a trickle charger overnight and no joy. Battery reads 2 volts and won't jump with a portable charger. It's getting towed to the dealer on Monday, but anyone have experience with this and what might be going on or is it just a dead battery. The lights, horn and window are what's confusing me. Thanks.
I've left my C8 undriven for 5 weeks last year and 4 weeks the year prior, battery is still fine. But, I made sure to top it off before I go on my long vacation and I do take a couple of long trips per year which definitely also fully charges the battery.
Sorry Jerry, but that's like saying the neighbor kid that's been kicked in the head by a mule agrees. I believe in AI as much as I believe I can get a genuine Rolex for $100.
This happened to me back in January. After having ceramic coating done. Car had sat on the lot 3 months prior. Every one on here said “need new battery “. I spent 200$ on a good battery charger. Brought it up to full charge. Two weeks later I had the dealer do a thorough battery test that was quite involved and took about 3 hours. Battery tested fine and has been fine ever since. I have about 6000 miles on it so far. I do hook the tender up if I’m not planning to drive it for a week or more. Sometimes cars get a lot of lookers and top raised and lowered, stereo, door open etc while not getting driven while in stock. Not always a bad battery. Mine could fail tomorrow but I doubt it.
