Don't know about in your part of the world but over here it is said that during your heavy vehicle licence test, shifting without using the clutch is an instant fail.
Reading a few operators manuals, I haven't noticed any advocating clutchless changes.
Maybe there is a good reason.
(Of course, that means bringing an automatic for the road test.)
with a little or lots of practice and FUN, we can learn to do just about anything AND act goofy and young and silly doing it. Thank you. :) :) :)That's the story of my entire conversion!
