acually u can't! the way the transmission is set up is its gear to gear and not sincromesh like a car!!! the only way to skip a gear would be if u were shifting up while going down a hill or somthn like that because a big rig only has so little r.p.m. to work with if u could skip a gear u would b luggn the engine at around 300 rpm which probably wouldn't work and vise versa u would have to over rev the engine about 1000 rpm over the red line which wouldn't b good either !!!! I've driven for a long time and every trailer combination possible in my life and i tell yeah if u could skip gears or try u will b walking home in stead of driving like i said the only possibe way to skip gears is to b going down or up steep grades and the truck is eaither slowing down fast enough or speeding up to catch two gears!!!!! hope that's helpfull 4 ya!!!! this is all based on the popular eaton fuller transmissions if u were driving somthn like a 5/4 transmission the gears are so short u could in a way skip gears thanks!!!!!!!
Who invented the Semi-truck?
As many as the purchasing agent ordered it with. It could have an Allison automatic with five or six gears, it could have an Eaton-Fuller manual or automatic with 9, 10, 13, or 18 gears, it could have a ZF Meritor automatic with 12 gears.
If the semi truck knocked on the garbage truck, yes.
There does exist a 21 speed transmission, although I have yet to see one. 18 is the highest you'll normally encounter.
For a North American truck, most of your average fleet trucks will run either a 9 or 10 speed transmission. Owner/operator and heavy haulers tend to have more gears - 13, 15, or 18 (15 speeds are a bit uncommon, though).
A vehicle with 18 wheels is commonly known as a "semi-truck" or "tractor-trailer."
Semi-articulated
When you pedal hard, the chain on your bike may skip gears due to a misalignment of the chain and the gears. This can happen if the chain is worn out, the gears are dirty or damaged, or if the derailleur is not properly adjusted. It is important to maintain and tune your bike regularly to prevent this issue.
Why does my truck skip and pop on one side and blows black smoke??
There is no prefix in truck.
Your truck may not shift gears because the transmission sensor is damaged or broken. It also may not shift gears because the transmission or linkage is damaged.
Tom Nelson invented the semi truck in 1945
