I think you need more channels to properly identify what you are feeling while driving.

TCC-status
Current gear
Commanded gear
Input speed (turbine)
Output speed

When I searched for those channels the only one that came up for me on my truck is Current gear, which helped alot while I was logging this morning.

I set the whole trans tune back to stock and it was much better. It's still showing a 100rpm slip while locked up in 5th.

I think I had all my TCC setting way to high. Because it locks in the low 30's in 5th i think, and I had it locking a 42. So now I'm going to add 50% to the Apply Ramp to see if I can get that 100rpm slip to go away. Then I'll disable the TCC 1-3 and leave TCC lock up stock 4-6. If drives better i will go back a slightly raise the TCC lock up under normal in 4-6.

So I set all the Torque converter Apply/Release back to stock. But I upped the TCC Pressure>Apply Ramp 50% and the TCC Pressure>Max Pressure 50%. I also 0 out TCC Desired Slip tables 1-6 and disabled Use DoD Slip function and disabled those tables.

That seem to cure everything. I just had the TCC Apply/release>speed>normal way to high in 4th,5th and 6th lock up.

I might go back and add 25% more to the Apply Ramp because I still have just a tiny bit of slip. But not enough to feel.
