I asked ZF why the ZF8 in our cars has a lower torque rating than models higher in their range, and this is what they said:

"The 8hp 45/50 is a smaller version of the 8hp70/75. The clutch drums, planet sets and TC are of a larger diameter. The components are able to handle more input torque as a result of the sturdiness of the components."
