It depends on the engine, but if I had a nine-speed in my truck I'd shift up at 1500rpm and down at 1100. But I gotta tell you, I've got a Fuller UltraShift two-pedal automatic and I will NEVER go back to a manual. If you are driving through Port Elizabeth, New Jersey, or downtown Chicago, just to name two of the more entertaining places to take 73 feet of rolling death, and you are trying to get to your destination without bending your truck, running over someone's car, or killing anyone, not having the transmission be on the list of things you need to worry about is really comforting.
Shift points are more the same as any other transmission. Trucking schools teach you to upshift at 1500 and downshift at 1000.... me, I like to upshift around 1900, so that it'll drop me right into the powerband. However, you don't want to go over 1700 with a Cat engine.

What is the difference in a 21 speed to an 18 speed in driving semi?
The difference between a 21-speed and an 18-speed transmission in a semi-truck lies in the number of gears available for different driving situations. Having more gears in a 21-speed allows for finer control over the engine's RPM and speed, providing better efficiency and performance compared to an 18-speed transmission. This can be especially beneficial in varying terrain or road conditions.

How do you drive a 13 speed semi truck?
A 13 speed is basically a nine speed with the option of splitting the gears on the top side. How I drive this one... depends on a number of things. If I'm loaded heavy and/or pulling a hill, I'll be more prone to splitting the gears as I up and downshift. If I'm empty, I usually won't push the splitter forward until I'm in the top gear.
What is the name of a car that is stick shift with no clutch?

A parked semi truck has no momentum. A moving bicycle does. If both the bike and the truck are moving at the same speed in the same direction, the truck will have more because it has more mass.
What is the maximum number of gears on a motor vehicle?
