I disagree with the C4 shifting quickly or smoothly. In comparison to any other hydraulically governed transmissions, it's got fantastic shift quality. In comparison to the new electronic ones, of course, it's a little slower, but the shifts are one of the things I actually LOVE about my C4.
In stock form, a lot of older automatics tend to be mushy, indecisive, and either shift too soft when you're on it hard, burning friction materials, or else shift too hard, barking tires and slamming into gears with a vengeance when you're puttering slowly through town. Many, like the AOD, also 'shift by committee' and seem to take forever to decide when it's appropriate to shift.
In contrast, the C4's simple design works beautifully. Your RPM determines when it will shift, and your throttle position determines how hard. When you're gentle, it shifts gently. When you're romping on the skinny pedal, it slams into gear with authority. It doesn't dither when you use the kickdown (full throttle) and whether shifted automatically or manually, it is never indecisive or slow to change gears.
Its only downside is the fact that it has only three gears. This favors an engine with a broad torque band over a peaky race-only engine. Some of that can be overcome with a high stall converter, but then you lose a lot of efficiency and economy. For a car that sees a lot of highway use (80 mph) I would stick to 2.80-3.25 gears.
I smile a lot. It makes people wonder what I'm up to...
