    A torque converter is part of the whole transmission system even if it’s a separate housing. When you buy a new transmission, it comes with a torque converter.

    Torque converters also create the majority of heat in automatic transmissions and are why automatic transmissions get coolers in the first place. How many manuals have you seen with transmission coolers?

      You’re right, granted, it’s probably just a bad name.

      Then, though, are those cooling systems systems you find in small cars sufficient to cool the thing under sustained high torque loads? Like stop and go city traffic on flat terrain with 2.5t of fully-packed caravan behind it? How much space and weight does it take to beef them up to be able to deliver the same performance of a manual? Is it still sufficient to hook the thing up to the engine cooler, how much more radiator area do you need? Does that even fit a car? Is that why SUVs are designed to hide small kids in front of them? (ok I’ll stop now).

        Stop and go city traffic isn’t all that sustained, because of the stop part.

        None of my cars so far have had any issues towing ~2 tons, I’m not sure why 2.5 would be that much worse.

        Of course, they’ve each had 400 newton-meters of torque out of their dinky little diesel engines.
