The only one I know of like that, is the auto stick
trannies in the old beetles. It was really just a vaccuum operated clutch. When
you went to change gears, you placed pressure on the top of the shifter. This
caused two electrical contacts in the shifter to touch. This closed a circuit
that operated a solenoid. The solenoid opened a vaccuum line to a vaccuum servo
which in turn released the clutch through a solid linkage on the transaxle.
They only made them for a few years (68 -74, 75 I believe, in the US anyway).
