2004 silverado, 4l60, 3600 Circle D billet triple disc. Looking for lockup settings. If i set it to on or off it's extremely harsh. It feels like its going to eventually break something. That was at 80% min and 100% max. Then I tried 25% min and 100 max, it feels perfect. But I don't want to toast the lockup. What settings are you guys using that do not engage too harshly? I can post the tune file if need be when I get home. At work right now and don't have my computer with me.

Consult circle D and the trans builder.
I?m the trans builder. I asked circle d already. I got it sorted. Thx
Looks like u need somehow to make lock up pressure rise from 10 to 100%
Don't know how to do it ( add custom pressure accumulator into TCC lock up line ? ) but I definitely wanna know how to do that )
Lot of help that is for the next guy! Do explain how you got it sorted.
Make the TCC minimum table linear.

I thought the old way was 90% to 99% on the min across the board depending on how harsh you would want and 100% on the max?
What did you do on your tune to make the lockup not as harsh?
I set minimum to 90% and max to 100% iirc. Tomorrow I?ll double check.
If he started at 80 percent and that was too harsh, then ended at 90 percent, and said that's better, something doesn't add up based on his harshness comment.
Post the .HPT file. A triple disc is meant to handle more abuse. With that being said, the softer you apply it, the longer it takes to engage it, the more it slips and displaces clutch material each time it engages. This goes for every clutch assembly.
