You are correct!
Don't forget the Aisin trans is a true medium duty and not de-neutered like the Allison in the GM's.
I am not necessarily doubting your numbers but I would like to know where you get them from. I would think the three diesel pick up truck engines will outlast the trucks they are put in in 99% of the cases. Very few people actually wear out an engine regardless of whether it is a Cummins diesel or a KIA gas engine. As for the transmissions I have seen ratings suggesting the Aisin and Allison are both rated for about 850 lbft of torque. Ford rates theirs considerably higher (1400 lbft) yet they all three weigh about the same and you seldom hear of any failing transmissions in the new diesels.
I agree all the trans behind big 3 diesels are good these days.
As far as the Allison in the Light duty/HD pickups VS a medium duty application. I was told personally by Bill Kondolay of DTT a premier diesel transmission builder that the Allison is not the same as what comes in the medium duty trucks/motorhomes. I have read this other places but I can't tell you where.
