OP it’s nice to see you have some perspective on the matter. We have enough Chicken Littles in this world. Hope your ownership experience is smooth going forward.

It's a Z06 ordered to his specification. You guys act like this was a chicken sandwich that came out mayo against your request. Some people would rather just let the components get replaced and enjoy the car instead of waiting 2,3 or more months to get a replacement car. Besides, soulsea did all the 'allocation list' whiners a favor by not getting reinserted in the front of the line which would have inevitably led to a 4 page thread in here about How Some Idiot got Screwed Out of His 'Spot' on a Mythical List. Thank you, soulsea. Enjoy your car.

The things that you cite are exactly what points to an assembly process failure, rather than a design failure. That the trans mission has held up behind 1200hp +, 1000+ lb/ft of torque with clutches and pressure boosts when it has a design limit of 590 lb/ft of torque tells you it is not a “fragile” design.

someone else mentioned case porosity. Also a manufacturing issue.

Four years into production and assembly issues would have been easy to resolve. We are talking about long term reliability, not short term 1200 HP little use/mileage reliability. Ill bet Tremec will revise the oiling and solenoids and probably the oil filtration system at the very least. And they are probably learning what the hardware is actually capable of relative to the programming/calibration.

Yeah don't they come with about 3 miles/

GM is building them now. I have 24k miles on mine, no problems. Fragile means weak and easily broken. Standing up to 1000 lb/ft is not easily broken. Maybe you mean durable. Almost all of the failures are less than 1000 miles. I have not heard about internal gear or shaft failures. Essentially all except can be explained by manufacturing and assembly failures, not fragile broken parts.

Four years in and design issues would have been solved. As far as I know, the design around pan attachment has changed. Design issues result in higher failure rates than we are seeing

BMW went back to torgue converter from DCT, but I don't know whether that decision was related to reliability. As for the Porsche PDK that was mentioned, it is, and has been for a long time, considered to be the best DCT in the world and the benchmark for by which others are judged.

GM wanted the C8 to watch European sports cars. They appear to have achieved it, not as unreliable as them.

The majority of extra price on the Porsche cars goes into their profit margin. They are just pricing their cars higher due to perceived value and what the market bears but that's a separate topic. As far as QC goes,
I am sure both lines have similar numbers of QC people. And I bet the BG workers get paid a decent wage as are the Porsche workers. I've watched some documentaries where they interviewed people that worked in various german auto factories. They are very proud of what they are building especially the ones that work on the more upscale model lines. What it comes down to is that people need to do their jobs well and not phone it in. Now, if the suggestion is that the BG lines are lacking in number of actual QC workers or maybe lacking in the actual process of what they are checking then that would be on GM. I will reserve further judgment on the C8 as it ages further. It's still too new to make a call on it.

Buy your dealer some doughnuts and coffee for breakfast or a pizza for lunch one day.

How's the transmission doing Soulsea?

soulsea

So far so good. I've been trying to put it in different environments to see if everything works as it should ... been manual shifting and automatic shifting in all the different modes with no issues to date. I'm incrementally pushing the car more and more but at a slow and deliberate rate, not only because I'm still in break-in mode, but also because in my head I'm not only testing the transmission but all the other components that were disassembled and put back together. I'm actually more mindful about things like a suspension component not being secured properly than the transmission failing, as the former can have dire consequences whereas the latter would merely be an inconvenience. As I put more pressure on all the components I'm gaining the confidence that the car is as good as new, that way when I hit 500 miles I can just let her rip and hopefully everything is fine and this will be all behind me. I should be past break-in in a week or so depending on pending travel planning, but I'll update the thread as I go.

That one should've been caught at the QC right off the line at the factory. Glad it worked out for you.

23/C8Z

idr the number but every select number of car off that line is run through additional tests for qc. I know this from my 2016 Z06 arriving at the dealer with I think 27 miles on it? When I asked what happened I was told they do a 23 or so mile drive every xx car as a random qc thing. I double checked this with the QC manager at the time Jeff strausser who confirmed that back then.

My 19 Z06 came with 4 miles on it.

So had the random qc thing happened to the OP he would've never dealt with this. Sucks. But glad all working out.
