BravestDog,
You can use the clutch on the class 8 but you still must match the rpm's. The class 8 transmission has syncronzers as well but they do things a bit differently. I have never been told why they do not make them to operate like the smaller transmissions. I would suppose that it has to do with the size and load they handle as well as making something that will go a million or more miles.
