Gotcha, I'm not denying that the autos are faring better than the manuals under mods, so far. I'm just saying it's reality that these cars are 1-2 years old at most and we don't know what these car's will be like in 5 or more. From experience and acknowledging the massive power capabilities evident here, I can pretty much guarantee you that anyone pushing decent blower power through these things regularly, will be on another trans, regardless of which one they had to begin with. This is particularly true if racing.
Companies can't afford to build in 100% blowup margins any more. Finite element analysis and CAD are used to build them just a touch stronger than needed. That's great for meeting customer expectations on a stocker, gas mileage and reducing weight, not so hot for durability over the long haul.
The trans, whether manual or auto, is usually the fuse in the driveline anyway. The rear end, being pretty simple, typically takes stuff well and no company wants a rep for blown engines so, good margin there but, you'll notice looking around the industry, trans is where the problems reside, for many manufacturers.
It's kind of like that knob who believed the sales manager when he said he could tune his car and put nitrous
on it and there'd be no warranty issues. Whatddyaknow, ka-boom and waaaaaaaa...hardly unpredictable.
