I felt like you were saying that a true manual was, if nothing else, equivalent to the DPS6 in terms of expected wear, longevity, and reliability because they, too, have clutches.However it sounds to me (from your tone) like you get the idea that I think a manual is inferior to a DCT. Not at all how I feel.
If that's not what you meant, then you have my apologies. I believe it's important to point out to anyone (not necessarily you, but anyone who reads this) that the DCT is not simply and "automated manual" as it was (and still is) commonly referred to. It's the differences that make a true manual more reliable and robust. And because of this, it's why I can reasonably say that the DPS6 is inherently flawed (in terms of hardware) since it simply cannot operate without destroying itself quickly.
All I can say is that if it were in fact a good design, it wouldn't exhibit shudder until we could reasonably expect the hardware to have worn out. Sure, 100k sounds somewhat arbitrary, but that's (loosely) based on decades of data from various platforms and types of transmissions (and variations on each of those).So say I tune it early, and I don't have shudder for 30k or more miles, then it comes back around 100k like you say. Then what, we say there's a hardware issue, right? I mean something has to explain it other than chanting "design flaw/poor design". My issue with this is it doesn't tell us what it is about the design that leads to the issue. Heat? Possible. Failing TCM ruining the clutch? Also possible.
5y/60k miles on the drivetrain is pathetic (though we all knew what we were buying, so that's on us). Heck, that's what the likes of Kia, Mitsubishi, and Hyundia offer on the entire car, with 10y/100k on the drivetrain. Statistically, they're going to gain more in customer base and brand loyalty than they'll lose on drivetrain warranty repairs, because any modern transmission simply shouldn't have trouble - let alone recurring trouble - before then.
The problem is that this isn't a proper experiment. There is no control. Your next clutch pack might make it 10k or 100k, and the only thing you can say for sure is that if it only makes 10k with Tom's tune, Tom's tune didn't fix it. You could draw a huge range of conclusions from any other outcome and even if one of them is right, we won't really know. So everything is anecdotal and anecdotal is not fact, even though it seems like a fact to the person with the experience.
Please don't get me wrong, I agree 100% that software is a contributing factor. I think you and I disagree on how much of a contributing factor it is. I maintain that the software is like patching a hole with duct tape: the hole might not leak for a while - and better tape will last longer - but the hole is still there. The DPS6 has a hole and Tom claims to have better tape. We won't know how good his tape is until it starts leaking again.
Possibly better, though the argument still is that Tom's tune works because it's specific to each car. The default Ford programming simply can't cover the variation between transmissions. It clearly works just fine for some, but for others - whether it's just variation inherent to the transmission or the driver's particular commute or a combination of both - it's not good enough. I don't know what Tom's success rate is, but I'm sure it's decent and even better when applied to a fresh clutch pack.I don't know man, but I'm certainly not saying this trans is the best thing since sliced bread, because it's not. I just wonder how things might be different had they not tried so hard to make this thing like a TC box.
I wish you the best of luck, truly. I just got a new pack (my 3rd) at 58k miles and the warranty on my 2014 was set to expire this month...now I get another 42k miles and 2 years to abuse these while I wait for the NHTSA to come back with their determination and for a proper lawsuit to punish Ford for being liars. I probably would have gotten Tom's tune later this month, but now I can't think of a reason to bother. I'll let Ford keep replacing my clutch pack. If I had Tom's tune already, though, I'd absolutely use it with a fresh set.
