I went to a triple-disk carbon fiber clutch after my first aftermarket converter died.

More accurately, if/when you install an aftermarket single-disk converter in one of these cars (definitely depends on year), you will not be able to achieve 0 slip and will ruin the clutch very rapidly. I believe it is a special spun/woven carbon material designed for the best of all worlds very few manufacturers make these clutches in popular aftermarket sized.

If you have a factory converter (at least this was the case on my 2013 C6), it is designed to 'slip' a few RPM without any ill effects. Just some helpful info from my experiences: It would also help to not let it apply at higher throttle points, especially with mods.The TCC apply ramp does not stop the pressure dropping until slip occurs, so far so good on the minimum adaptive though. I am not even allowing it in any gear but 5 and 6, stock cal allowed it in 3 and 4 at like 22 mph or some ridiculous thing. IMO you really want to stop regular tcc slip, as it will put clutch material in the system and start mucking up the valve body, then all hell breaks loose. Then it will increase pressure with slip at the rate allowed by the chart, which is at a pretty wimpy rate. The tcc regulator offset affects holding pressure as well, but it seems to be that the total holding pressure is the tcc regulator offset + the tcc apply ramp pressure at zero slip. Fuel economy increase of milligrams of fuel from the reduced engine load.pffft. I will let you know when I log next but I suspect that even if you command 0 slip, it will gradually lower pressure until it slips and then ramp up pressure according to this ramp chart. If want to email me a tune I am sure I can point you to the correct tables to tune.Look at your tcc apply ramp chart as well. Very few from any car so this really seems to be more of a heavier vehicle issue for sure so thinking not only the weight but assume the tune is so it applies less abrupt so people dont bitch about feeling lockup apply. The 6l80 is problematic and see a ton of them from trucks and suv now. Hopefully it isnt too far gone and can tune it out as I have on a few that drove it that way a while. Up the pressure to the lock up cluch, raise the mph it locks up at, make it on off get rid of all the slip rpm (I have done this with good results on 6l45e ats trans that have this issue) or just lower slip rpm so still allows some but not much but will have to add to pressure too. If the clutch isnt too damaged already you can do a few things. The new world we live in with dealers not wanting to warranty anything. You can go back stock and try it but dont be shocked if they send off the ecm and check it for a tune.

Since you have tuned it they will most likely check find it and not warranty the truck. I know the aftermarket stuff we use in rebuilds are much better have a better lock up clutch. My buddies bone stock 2017 with 6k miles is doing it already. I build trans for a living and like was posted already these have major issues with torque converter failures and shudders.
