Not sure if this is the exact tranny in the LCI-but in general this is a complete explanation in equistite detail of how the ZF auto trannies work. Its a pdf by ZF

very cool read-about how the tranny adapts-and whawt factors it takes into account.

For example I found it interesting

D mode-has 2 maps-ultra economy and economy

DS has 2 modes-sport and ultra sport

Within each of those D and DS modes it takes the following into consideration
1.How fast the pedal is accelerated, how fast the braking has been applied and DME feedback from engine speed
2.It also takes into account later acceleration forces-but this does not have as much impact on which map it chooses as does the stuff liisted in 1.

Anyway that is the kind of detail in the article
