Message: [QUOTE="Charles, post: 635856, member: 103"] Those are autos genius... Planetary gearsets, actuated via clutch packs.... strangely familiar.... My 4R100 does exactly that each time I press the little red button for upshift and downshift. If you run a bruno in front of a lenco, now you've really worked hard to have a non-od, non lockup version of the same thing with far less continuous capacity. In the sense of this thread, a "manual" would be the option where power is disconnected from one gearset, and reconnected to another on a shift. What you described above is EXACTLY what happens inside a 4R100 on a shift and nothing like what happens in a ZF6. Pull a lever with your hand to engage the clutches, pop them in with an air solenoid, or shove them in with hydraulic fluid, either way, a planetary set is being engaged the same way for a lenco, liberty or 4R100.
