Hello dear forumists. With an unsynchronized transmission such as oldtimer tractors or trucks, you have to give intermediate gas when looking down to bring the gear pairs up to speed, so that they can interlock. It works quite correctly when switching down(!) so: uncouple – idle – plug in – intermediate gas (can possibly take quite a while with the single cylinder engine with high momentum mass – uncouple, insert lower gear – plug in – Today’s gearboxes make this procedure unnecessary and yet it is often given intermediate gas, even if in the “light” version, i.e. without the re-coupling in the idle mode, which one saves itself. Importantly, the accompanying gas shock appears when gear changes down. NEXTly this is not, although one might have the feeling that the gears snap a little softer. My question refers to an observation of some truck – bus – and small truck drivers. They give between GAS IN HIGHER EDUCATION, something that is totally unnecessary, actually hindrance to a good change of gear. Why are they doing this? The only reason I can think of is that it sounds cool. Or is there something I don’t know?
