A couple of points about automatics...
1. WOT kick-down has been around forever. Older cars, 1960's, 70's.. possibly 80's too, were cable actuated (well, most everything was... that or vacuum). At wide open throttle, they'd drop a gear, so for a Powerglide, it would drop from 2 to 1 (only 2 speeds), for a Turbo-Hydramatic, it drops from 3 to 2 (three-speed). Of course, with later tranny's with more gears, such as a 700R4... gear numbers increased.
2. One trick often used with automatics is to increase the "stall speed" of the torque converter. I believe this involves changing the viscosity of the fluid, but may also involve changing the number or shape/size of the internal vanes, so that the engine revs higher before power is transferred through the drivetrain. This has further been augmented with the introduction of lock-up torque converters (1980s'?) which provide an actual mechanical connection through the tranny.
Automatics do have a tendency to mute the driving experience, but this is less pronounced on large engines that can produce decent torque at low RPM's. Little 4-bangers don't cope quite so well, although, todays automatic transmissions are super good compared to those of decades ago.
(This is a double-post because it seemed fitting to two different threads!)
