T43 - 6LXX - TCC Adapts - Strange Behaviour

[PHLTHS]

Hi All,

For some strange reason, once I enabled TCC adapts on my 6L50 / T43 controller, at steady state driving, Speed, Torque, TPS all steady, I see the TCC pressure just constantly increasing.

Any idea whats going on here? I was under the impression that the TCC Adapts are meant to lower the TCC pressure until it detects slip above what is set in the slip tables (in this case 0) and then increase just a little to hold that slip rate.

I've attached my log, my tune and also a screenshot where you can see the TCC Desired Pressure just keeps increasing.

I think I have solved the problem. By increase only the values in the 0 column for the TCC Apply Ramp, Resetting the Adapts, and also re-adjusting the TRQ Cell Breakpoints, the TCC Pressure now does not run away.

Log, Screenshot and Tune attached.
