An electric car transmission is a usually a simple reduction (two gears). An ICE transmission is usually a six speed shifter, often with hydraulic controls. A world of difference in terms of weight and maintainability.

That's just talking gearbox. Then there's casing, shafts, mounts, cooling. The difference in number of gears is the smaller part.

Please don't pretend it's anywhere close in complexity and weight to the ICE. Of course if you include batteries then it's heavier. But that's why people are excited for any small change in battery energy density.
