Sure they are rated for more torque on paper. But their cost to build is substantial
and is very possible the reason for their failure in higher HP applications is their complexity and nobody really knows how to make them work right.
Where a 4l80 is a simple animal where you just need 240psi apply pressure on a good waffle clutch pack and it will hold a bunch of power. And the simple stacking of solenoid for shifting vs Clutch on clutch is very very different.
