Learning to bulldoze a semi truck properly requires lots of training and feel, merely if you're curious about the basics of shifting one, you can get a primer on the steps that you'll need to practice if you want to bulldoze the big rigs. Learn how the gear shifter workers, how to shift between gears, and some tips for knowing when to shift.

1. 1

   Understand how the gear shift differs from a normal vehicle's shifter. If you're familiar with a manual transmission, the bones principles of the Eaton-Fuller Transmission shifter–the manner used in many commercial trucks today–is similar, just more than complex. Basically, it's oriented like a five-speed, but with a total of four different ratios at each position, which you toggle by a combination of switches and positions. This results in a full combination of 18 unlike speeds.^[one]

   • The shift knob has two switches controlling air-actuated gears. One is the range switch, which needs to be set on "Low" for gears Lo-4, and the other is the high/depression splitter, which is used to toggle between the low and loftier setting at each gear. Your index finger operates the range switch, which allows y'all to flip betwixt loftier and low at each gear position with your thumb.

2. two

   Learn the gear shift blueprint. Most gear shifts have a diagram displaying the shifting pattern, which volition assistance to inkling you into the organization of the gears.^[2] The depression gears are unremarkably differentiated from the loftier gears by color, and contrary is indicated by an "R."

   • Gears 1-4 should all exist straightforward, but then to shift into 5th gear, you shift dorsum to the first position, and the pattern repeats. First gear is in the same position equally fifth, second in the same as sixth, so on.
   • Remember, at each position, you lot also have a total of four different speeds, though but 2 volition be accessible, depending on where you shift from. In kickoff gear, you lot've got 1L and 1H, as well equally 5L and 5H.

3. 3

   Practise the gear pattern of the semi while the truck is stopped. This allows you to become familiar with the gear pattern so y'all can shift up and down without looking. This will assistance you lot go on your eyes safely on the road while driving.

   • Grip the gear shift so that your index finger is available to piece of work the range switch, and the heart and thumb can piece of work the high/low splitter.
   • If you don't have feel operating the clutch and driving a manual manual vehicle, shifting a semi truck is going to have a much larger learning curve. Operating the gear shifter past itself is challenging enough, so you demand to be very comfortable operating the clutch on a regular vehicle before you effort to drive a semi. Do on a regular car.

1. one

   Start the truck. Hold the clutch pedal to the floor, as you would to showtime a normal manual transmission vehicle. This stops the transmission gears from turning, which allows the shifter to slide into gear. Select "LoL" past moving the shifter into the Lo-gear position, usually left and dorsum.^[iii]

   • Check to make sure the range switch is in the depression position (downward), and the splitter is also on "L" and you'll be fix to start the vehicle.

2. ii

   Push down the accelerator and slowly release the clutch. Equally you might judge when the vehicle's got 18 different speeds, getting the truck into Lo gear on Depression setting will get you lot going about one mile per hour, if that. Once y'all've slid into it, release the clutch and you'll probably be set up to shift into Lo-H.

   • To shift into Lo-H, you'll change the splitter to Loftier gear to shift into high. You lot need to depress the clutch slightly, just not all the manner to floor, and then let it out to shift into Lo-H.

3. 3

   Double-clutch to shift into first gear, low setting. Depress the clutch once again slightly (not to the floor) when the RPMs reach first-gear range, and switch the splitter back to "L," then pull the gear shift into the neutral position and release the clutch. Depress the clutch again, all the way, and push the gear shift into first, every bit you release the clutch.

   • This is called double-clutching, and information technology'southward necessary because y'all can't split between depression and high on the splitter while you lot're in neutral, significant that you have to toggle from "H" back to "50," so shift into neutral, then operate the clutch again to get it into first. It'south a lot of work.^[iv]

4. 4

   Continue this blueprint through the kickoff half of the gears. After yous shift into 1-L you can flip the loftier/low switch up into the high position, continuing to accelerate and continuing this basic pattern through the upper gears.

   • Repeat the previous steps through 1-H, ii-Fifty, 2-H, 3-50, 3-H, 4-L, and 4-H. To make the half steps, go along pushing the splitter push button, releasing the accelerator, pushing in, and releasing the clutch.

5. 5

   Switch over to fifth gear when you lot're fix. With the splitter switch in "Fifty," flip up the range selector to five-H, which will permit you to avoid grinding gears when you switch back into the first position. This is absolutely essential. Switch the range, and so double-clutch-shift back to where 1 was earlier, and information technology volition be 5th gear.^[5]

6. 6

   Continue shifting through the higher gears. The basic principles now repeats itself. Go on shifting and toggling betwixt "Fifty" and "H," shifting up through 5-H, 6-Fifty, six-H, 7-L, seven-H, 8-L, and, finally, viii-H.

   Employ the color indicators on the tachometer. Near RPM gauges should be colour-coded, with 1500 rpms at almost the top (12 o'clock) of the guess, which is typically colored green. This is the ideal place to shift between gears.

   • 1700-2100 is typically across the signal where you should be shifting, with the exception of going downhill. This region is typically colored Xanthous, with anything above colored blood-red.
   • If you're less than 1200 rpm and try to shift, the engine is likely to splutter and possibly stall.^[6]

2. two

   Become used to the general shifting conditions. Afterwards a while, you'll be able to familiarize yourself with the full general positions that you lot need to shift, but in didactics school, yous learn a few bones rules of thumb.

   • Be in meridian gear at 50 mph (fourscore.five km/h) or greater. Generally speaking, if you're traveling at highway speeds or greater, y'all should be at top gear always.
   • Exist in fifth or sixth gear for abrupt turns in metropolis atmospheric condition. To avoid stalling, it's good to be switched over into the upper gears.
   • Other general speed guidelines volition vary from transmission to transmission, for different trucks. You'll need to ask your instructor or other experienced drivers for tips.

3. iii

   Downshift whenever you're slowing down. To downshift, you demand to slow downwards to the rolling speed past hitting the brake, and then select the gear for that range. Typically, you lot need to rev up to 1400-1600rpm, then slip the transmission into the proper gear for that speed range.^[seven]

Add New Question

• Question

  Where is the splitter push on my shifter?

  

  On every Eaton transmission at that place is a unlike setup. For the one that is mentioned, the "splitter" is on the left side of the knob and the range selector is the toggle switch directly on the front portion of the shaft. On a ten speed, you do non have a "splitter" but only a "range selector", however on a "Super x" all it has is a "splitter".

• Question

  Can I put information technology in neutral and start breaking instead of irresolute down?

  

  That's too dangerous because you are free wheeling in neutral and may proceeds and then much road speed that you'll be unable to get back in gear in time.

• Question

  How do I shift a truck into neutral?

  

  If in gear, pull out and yous'll exist in neutral. Neutral is what yous should ever put your truck in when parking and when starting it upwardly.

• Question

  What does a range switch do?

  

  The range switch for when you go through the first set of gears, Lo/1-4, then when yous go to the last position for that range, you pull upwards on the range selector and get through the gears again. An easy manner to remember this is, Lo through 4/v is all below 15mph, and 6th on up is 25mph+. Having the ability to "split gears" on 13s and 18s are prissy for trucking on steep grades. Split gears are 500 RPM steps instead of 1k. With a 13 you can only divide 25mph+ and on 18s you can split The low range (0-15mph) and the high range (25mph+). 18s are ideal for logging trucks and 13s are ideal for mountain driving. Supers 10s are best to learn on, equally they exercise non crave y'all to get through the pattern twice.

• Question

  When I split, practise I use the clutch?

  

  No, y'all just elevator off the throttle to release the pressure when upwardly shifting, and for down shifting, you will give information technology a little shot of fuel to bump upwardly the RPM.

• Question

  How practise you double clutch?

  

  You lot step on the clutch, put the gear leaver in neutral, clutch, and and then downshift.

• Question

  How do I shift out of neutral to the correct road gear? Is there a chart that matches the right gear to the right speed?

  

  Each truck is different, depending on it'south equipment. For the higher gears, add the 2 digits of the speed and that tells you what gear you should be in for 1300 engine RPMs. For example, at 15 MPH, 1+5 is 6, so you should rev the engine to 1300 and shift into 6th. For 25 MPH ii+5 is seven so shift into 7th at 1300 rpm.

• Question

  When double clutching, is it necessary to press the accelerator?

  

  It depends. When selecting a higher gear, no. Since the RPMs need to fall, you don't have to do anything else. For a lower gear, yes, you need to give information technology some throttle. Since large diesel engines respond fairly slowly, this normally ways a very brusque stomp of full throttle.

• Question

  On a 10-speed, can I start from the sixth gear?

  

  Probably not. If it is loaded, definitely not.

• Question

  What does "RL/RH" mean?

  

  RL is reverse and would be with your range switch down or in depression, and RH would be reverse with the range switch in the up position or in high.

• Do not use the splitter button in neutral.

Professional Semi-Truck drivers don't use the clutch except for selecting the first gear. Mind to the engine audio to estimate shift points, and lightly experience for the gear, don't grind the tranny. Also, depending on load weight, you don't take to dissever every gear

Article Summary 10

To shift gears in a semi truck, start by pushing down on the clutch pedal and moving the shifter into the Lo-gear position. Next, button down on the accelerator, release the clutch, so depress the clutch slightly every bit y'all pull the gear shift into neutral. Then, depress the clutch all the way to the floor, and push the gear shift into starting time as you release the clutch. Continue this design for the outset half of the gears, then flip the range selector to five-H, or 5th gear, to avert grinding gears when y'all switch back into the showtime position. To learn more, similar how to downshift when y'all demand to slow down, keep reading!
