Type of transmission

sers@all! I hope I can ask the question here without getting bugged, because I don’t find a general subforum for the topic. My question: Is there any vehicle whose gearbox consists of planetary drives, which are sequentially switched on by the driver? I mean no automatic circuits, but which one at least switches the movements by hand (can also be semi-automatic, i.e. autom. clutch)? have only found page-wise dsg-circuit discussions so far but not about something like that.
