Basically it's a 4 gear ravigneaux planetary gearset and 2 speed lepeltier planetary gearset when combined gets 6 speeds but put in more magic dust, newts eyeballs, dragonballs and level 100 wizardry and you can get 8 speeds.
It may sound complicated, but it has fewer parts than either the GM 8-speed, or the ZF 8-speed. It would be interesting to know what went wrong with the AE80F in the Landcruiser in question.
