2018 Silverado 5.3L 6L80. Transmission is rebuilt, and new Precision of New Hampton HD (billet) converter. Pretty much a newbie with HP Tuners. Used HP Tuners to disable TCC in gears 1-3, set 0 slip in 4 through 6, set TCC Regulator Offset to 90psi and gain to 1.0. Figured then I would see a really firm lockup but instead I see TCC pressure as low as 20psi and some TCC slip while cruising in 6th gear. In the image below there is a long section at 65mph on cruise control. I expected to see higher TCC pressure and no slip, yes? Seems wrong to me. Suggestions? On the road, the TCC lockup feels firm.
And a minor issue in the Scannner - the current gear does not show on the scan, but the instantaneous value is correct, see top left in Channel, value is 6. Is the chart problem because the 'gear' is not just a number (scalar), it can also be Park or Reverse?
Thanks.
