Clutch in an automagic transmission?

If you saw the PDK out of a Porsche, it is not similar to the current seven speed manual, it is the seven speed manual, complete with gears, synchro rings and everything else you would find in a manual gear box, the big difference is that it uses a dual (one of even gears, one for odd) wet clutch system, and everything is controlled by computers, right down to "blipping" the throttle during down shifts.

No, the Vette and the Hellcat do not have a torque converter. Did you bother to read the links I posted?

From the Corvette link

With four simple gearsets for optimal efficiency and five clutches (two brake clutches and three rotating clutches), creative packaging enables the new eight-speed automatic to fit the same space as the previous six-speed automatic – and the powerflow only uses two open clutches for low spin losses, which enhances efficiency. Extensive use of aluminum and magnesium also make it more than eight pounds (4 kg) lighter than the six-speed.

and the Hellcat gets this transmission

They are all automatic transmissions as they shift the gears for you. Porsche, Ferrari, Stingray, Hellcat, BMW, Lambo, Nissan GTR all of them are automatics using a clutch system.

Sorry, but perhaps you need to re read them, from the Corvette article:

"Unique clutch and torque converter specifications matched to the torque capacity of the Stingray’s LT1 6.2L naturally aspirated engine and the Z06’s LT4 supercharged engine distinguish the applications for the different Corvette models."

And in the Doge article the transmission, with a torque converter clearly visible, as it is in the photo above.

They are both conventional automatic transmissions, not an SMG like the PDK.

Yep you can plainly see it is a auto trans, only difference is heavier duty, and computer controlled, allowing buttons for shifting.

It's not the torque converter of the old days and a clutch shifts the gears on the Vette.

The torque converter takes the place of a clutch on a conventional manual transmission

This Is How An Automatic Transmission Works

The picture of the trans for the Hellcat I used the wrong picture. The hellcat gets the wet multiplate clutch.

Sorry, but you are beating a dead horse here. The transmissions in both the Dodge and the Corvette are significantly technically modified automatic transmissions, but at their cores they are closer to the Powerglide or Powerflites from their respective ancestors of 60 years ago than they are to an SMG.
