The hydraulic automatic transmissions are less efficient than transmissions with a clutch plate directly on the flywheel, including manually shifted, Continuously Variable Transmissions (CVT), Automated Manual Transmissions (AMT), and Dual-Clutch Transmissions (DCT). Electronic Automatic Transmission (EAT) is also known as an Electronically Controlled Transmission (ECT), or Electronic Automatic Transaxle (EATX).

The electronically controlled "manual" transmissions are expensive and have a lot of bugs to work out and don't last as long as hydraulic transmission and nowhere near as long as a manual transmission. If not for bullspit EPA fuel efficiency standards, consumers wouldn't be saddled with the costs and problems associated with the electronically controlled clutch transmissions.

One potential future option would be a clutch transmission that a driver could select either computer controlled or manual controlled. In traffic? flip it to automatic. Traffic clears? flip it to manual and drive with better control of your acceleration, control in turns, and control on wet roads.

You also have deceleration with the manual control which you don't have with the hydraulic transmission or the electronically controlled clutch transmission.

Your electronically shifted manual “future option” already exists and has been around for a few years, and I’ve owned two such cars (a Ferrari and an AMG GT).

—”The electronically controlled “manual” transmissions are expensive “

Our son HAD a VW diesel with a DSG, the dealer charged over $600.00 for the fluid change at 40k miles!!!

Less than two gallons of fuel will take you 100 highway miles and the trans service cost $1.50 for the same hundred miles!!!
Diesel was about $2 a gallon at that time.

I was gearing up to do it for him for about $200 parts and fluid.
And purchase a VW OBD reader to check levels and reset.
But VW made him an offer he could not refuse.
