Many automatics these days are manual transmissions with a computer controlling the clutch. They have nothing in common with the slushboxes of old, the oil is just for lubrication.

ZF 8HP is still a traditional torque converter transmission. Most high performance or high torque applications use that design. Dual clutch automatics or automated manuals can't take it.
Tremec makes DCTs that are used in 800hp Mustangs and 1000hp Corvettes
Virtually every truck has an automated manual transmission, every EV 2-speed is a DCT, Porsche uses PDKs etc.
Every truck? Like which ones?
As an American (land of the pickup truck) I can't think of any

Citation needed. By truck if you mean commercial truck (lorry, artic, etc.) then no, Allison still makes hydraulic automatics which are very common in vocational work the world over.
Maybe in sports cars but the majority of vehicles still come with hydraulic autos or CVTs.
Even slushboxes tend to aggressively lock up the torque converter. It's usually only in a "fluid dynamics" mode for brief moments. (Except maybe on a gentle hill start)
I mean, certainly the VAG group likes to use their dual clutch automatics, but "true" torque converters are still very common. ZF makes them for like a million different cars, and AISIN makes them for the Volvo and Geely group.
