If you are driving a loaded tractor trailer, you would downshift to gain more power when going up hill and downshift to control speed when going down hill.

No such thing. Are you asking about a Super Ten transmission, or a 13 speed transmission?

Do you use a tachometer and a speedometer to shift on a tractor trailer?

That's how you're taught - use the tach to determine when to shift, and the speedometer for recovery speed if you lose a gear. After a while, you get to the point where you know when to shift by the sound of the motor.

How do you move weight on semi trailer?

The question's a bit vague. If you're referring to distributing weight once you're loaded, it depends on what your trailer has for axles. If you have fixed tandems or a fixed spread axle, you would have to move the load itself. If you have sliding tandems, you can move them forward to shift weight from the drive axles to the trailer axles, or you can move them back to shift weight from the trailer axles to the drive axles. If you have a sliding fifth wheel, you can move that forward to shift weight from the drive axles to the steer axle, or you can move it back to shift weight from the steer axle to the drive axles.

How do you shift tractor trailer gears?

If you have a low speed such as an 8-10 it is a simple double clutch and shift. But, if you have 13-18 you will have a low and high range switch. 18 Speed is simple for me It is in low range shift 1-4 at 4 switch to high range. Shift 4-8. So, in reality you are not actually shifting 18 times.

What do you need to go from a Florida CDL B to a CDL A?

As far as written tests go, you only need to take combination vehicles and air brakes (if applicable and if you don't already have it). The difficult part is going to be finding a vehicle for your road test. You need to test in a tractor-trailer, or else you receive a "no tractor-trailer" restriction. If you're looking to go OTR, or to just go work for a different company and drive a tractor-trailer, you really should go to a truck driving school. If you don't have Class A experience in a tractor-trailer, any company you apply with is going to treat you as an inexperienced driver, no matter how much Class B experience, no matter how much experience you have with unsynchronised transmissions, etc you might have. If you can't afford the school, and are seeking an OTR job, several companies offer their own school in-house, which is free of charge provided you work for them for a year or so. Additionally, if your work had you driving something like a single axle straight truck, you had either a synchronised manual shift transmission or an automatic, in which case, you especially need to go to truck driving school. The unsynchronised transmissions found in Class 8 trucks are a lot different, and do not shift the same way.

At the rear of the tractor their will be a primary and sometimes a secondary tank these are called air tanks at the end of each shift you need to pull a cord of sorts on the bootom of the tank this opens a release valve that will allow the air to escape the tank. Do the same thing on your trailer.

How is Tractor trailer down shifted?

If you don't know how to downshift (and upshift) and unsynchronised manual progressive shift transmission, you really need to go to a truck driving school. You're not going to learn how simply by read about it. In school, they'll teach you to drop the RPMs down to 1000, pop it into neutral, kick the accelerator to 1500 RPMs, then drop it into the next gear. It might look simple enough on paper, but you're not going to get this down without some hands-on experience.
