What's the difference between 5HP30 & 5HP24 trans?

["Richard Vaughn" <rav3@xxxxxxxxxxx>]

I have noticed several sites that list the transmission fluids for the 
different model BMW/GM transmissions, show a 5HP30 (A5S 560Z) transmission 
used in the earlier E38 (740 & 750) and a different model, 5HP24 (A5S 440Z) 
for the '96 & later 740's. However the 750's still used the 5HP30 till the 
end of that model E38 (2002). The specs show the earlier transmission 
holding 13.1 liters, where the 5HP24 (4.4L) only holds 9 liters. Was the 
5HP30 a 'heavier duty' transmission or what? Can anyone shed any light on 
this for me?
