It's kind of weird how they make a big deal out of a design that was the norm on most top load washers through at least the 90's. We've severely backslidden the last couple of decades. Yay for progress, right?
Jerome, the Speed Queen model in the disassembly videos is a TR7. As you know, the TR series doesn't have a transmission at all ... which of course is the reason you hate it.
Which obviously translates to poor wash action without a transmission. It's called the perfect wash system. Too gentle in my opinion. I have sturdy cottons.
