The last one that didn't have lockup was the Geo Metro 3 cylinder 3 speed, like a decade ago. Many lockup during acceleration, (MB 7 speed, ZF 6 speed autos, Aisin 6/8 speed auto, JATCO 7 speed) there is no sense having the torque converter unlocked when you are above the engine's peak torque. They also have a feature called continuous slip where they nearly lockup at low loadings (like city driving) for better mileage. (the slip is to isolate the lugging feeling) Chrylser calls theirs EMCC, GM ECCC, etc, etc. In the real world, automatics usually get better mileage than stick shifts, but it depends on the skill/experience of the driver and the usage (pure city to pure highway) The CVT's with torque converters (Nissan) usually lockup at low vehicle speeds, above 5 mph to about 10mph. VW's double clutch transmission doesn't 'theoretically' outdo manual transmissions, it actually delivers better performance & mileage. They documented that that when it was introduced. That is why Chrysler was putting many eggs in the double clutch transmission basket (7 speed for the Dodge Ram) All torque converters have lockup.

It doesn't matter how many forward gears you stuff in there, it still has a fluid drive - AKA the torque converter - which soaks up energy like a sponge, resulting in reduced fuel economy. Some have "lock-up" torque converters, but these are not enabled while accelerating. Basically, you're not using the lock-up feature very much in town, and that's where most Americans do most of their driving. Transmissions like the VW "DSG" transmission - a true direct-drive manual transmission (with two automated clutches that are otherwise conventional) that shifts automatically - could theoretically outdo a conventional manual transmission in fuel economy, but a conventional automatic with a torque converter never will.

If you don't want to actively drive, just leave it in D-can do that with a stick shift? When you don't want to delegate responsibility, you move the transmission selector to the manumatic gate. Unmaintained older automatic transmission can have more latency due to an old transmission filter, and more clutch pack wear requiring more fluid to actuate.

Either get a manual transmission, or let the automatic do what it's supposed to do by itself. Automatics tend to have slower response as the get older. And they are far more expensive to rebuild than replacing a clutch on a manual trans. What is the point of a manumatic?
