I was talking about non-torque-converter transmissions, which can fully disengage the clutch. I observed a Porsche PDK doing the following:
1. Clutch always engaged except with coast function (which never turns on if you're not using the manual shift despite their claims) and when at a full stop with brake pressed.
2. Clutch is only barely engaged when rolling, it slips a lot and you need to give it gas to maintain speed at idle in 1st gear
3. Clutch only has just enough pressure to prevent slippage once you're going, pressing the gas will cause it to slip momentarily.
4. Pressing gas will automatically engage the clutch even if you're at a dead stop.
Basically it kind of emulates a torque converter except when your foot is firmly on the brake pedal.
