On a non synchronized transmission (crashbox), if you try to shift into the next gear without revmatching the input shaft, you'll grind the hell out of it.
It doesn't work like the synchronized transmissions in regular cars.
Not all big rigs have crashboxes, but most of the larger ones do.

@TheRockisSmokin, all good buddy.

@fairmontxf87 thank u for explaining

@TheRockisSmokin, trucks have more gears than you could throw a stick at, equipment is more heavy duty and require this technique to minimise the damage in the gear boxes, some or most trucks have two gear boxes for high and low gearing and are usually fitted with two clutches and a clutch brake hence the reason for the double clutching, plus it saves strain on the motor to prevent it from jerking during shifting.

When i first started i double clutched alot but then i got the hang of floating my clutch its a little bit harder to master but more fuel efficient and better

@piratebobstreasure woohoo, someone knows not to double clutch it like a four speed. i have literally seen guys who put the clutch to the floor when shifting, they obviously dont know what a clutch brake is.
