I've been driving an automatic since I passed nearly a decade ago. In that time whenever I tell anyone I drive auto, it's usually met with some level of derision. I think that attitude is changing, but I'm still kind of confused by it in the first place.

Why?

I mean, my gripe is more about the lack of power on the wheels. It's less about the time it takes to re-engage the clutch, more the overall time the clutch is disengaged. I want to accelerate briskly (not flooring it) and then cruise at a steady speed, to achieve maximum fuel efficiency. A good automatic handles this very well, and generally makes driving easier and more relaxed. Sure, changing gear manually and getting the clutch right can be fun, but it's objectively a worse way of doing things.

Dropping 250lbs and removing the torque converter (~2% loss alone) will do more for overall fuel efficiency for your car than anything those automatic transmissions can do.

Yeah, I get that computers + improved automatic modes of transmission control (ex: CVTs or Dual Clutch Transmissions) can improve engagement times. And the removal of the wet-clutch/slushbox of automatic transmissions grossly improves efficiency. But these units are still heavier in practice than a dumb, manual clutch.

I don't think any automatic transmission beats a manual in efficient driving yet. Because weight is king. Automatics (at least, DCTs and CVTs) are finally reaching the response times of a manual transmission by having more direct connection of accelerator pedal to the engine... but the weight issue, cost-issue are still there.

At least modern transmissions basically never brake down anymore. (CVTs, Dual Clutch, and more are all basically going to last the whole lifetime of a typical car).

Tbf the whole argument is basically moot with electric vehicles taking over.
