Been driving two years now but in an automatic today was first tie in manual and I keep grinding the gears sometimes I dan shift up no problem then the next I can’t get it in gear and forget about down shifting I am doing the double clutch rev the rpm to 15 16 rpm but once I’m in netrual I can’t get it in any gear I’m fighting to get in gear till I’m real slow then I can get it in gear but it’s nerving wen trying to turn corners and trying to down shift or if the light turns red then I’m just relying on the foot break automatic spoils you for sure I love driving manuals in cars I just have to learn in semi truck it’s just weird that one time I shift all gears good then the next time won’t up shift right now the truck I used today was 1996 year so not sure if that had anything to do with it and no one likes that truck so many it both me and the truck not working properly hhha also have to learn the speed for the right gears so good thing for u tube for me to learn proper ways to try just hate being a rookie at shifting but e all have to start some were
Double clutching cause wear and tear on your knee I don't have much cartilage left in mine so I will float gears as I have for the past 22 years never had a problem with a truck
7:08 What he said here is actually incorrect. The shift is matching gear to road speed. Not RPM to road speed. The RPM is not one would drive gears by. It is the ROAD SPEED by which one shifts to gears, both upshifting AND downshifting. RPM will also change behavior to gear when towing heavy, and heavier, loads. (The same vice versa; the RPM reacts differently when you have light load, or empty). RPM is NOT what you use to shift gears! It could be different in different conditions up to 350-400 RPM! (For example, the gear could be working correctly anywhere from 900 to 1400 RPM!). Especially in the difference going down grade (descending) versus going uphill (climbing) AND whether with a heavy load or heavy haul versus empty or lightly loaded. For example, 9th gear starts at approximately 35 miles per hour (on a flat grade). Incidentally, to match the gear to the road speed, there are many instances where a double down is required to be instantly in the right gear due to rapid loss of road speed (for example when in a rapid change of uphill grade). Honestly, (not intending to be overly harsh or bluntly straightforward) only a moron semi driver driving a tractor trailer day in and day out for a living 50-69 hours a week would be double clutching every time you changed gears. AND your knee will have carpal tunnel or joint disintegration within two years. Floating gears is the hallmark of a true seasoned veteran *PRO* semi driver. My estimation is 99% of tractor trailer drivers who drive manual transmissions double clutch for the last time during their CDL license drive test. The rest of their daily working lives in driving career, they float gears. One quickly becomes skilled, to when you no longer hear the soft "purrrr", but just *silence* 99.9% of the time when floating out of and into gears. And if you're not effectively at times using double down when running into sudden changes of uphill grades (for example, 10th to 8th, or, 9th to 7th), you are probably *going* to damage or wreck the transmission, because you will need to be in the correct gear matching the correct road speed *instantaneously* .
Good video if you already know how to shift, and floating saves the clutch, but if you miss, and you will, it does grind the gears. guys with 20 years driving still grind gears every now and then. notice the guy never looked at his mirrors, kinda wonder about that, maybe he was on a test track with no traffic.
That's the way I was taught to do it by seasoned instructors, now the guys that build the transmission say the same. So, no shame if you do it some other way, just stop telling rookies that double clutching ruins the transmission, it's all the way around. Note: the first clutch doesn't have to be too deep or pronounced, getting to Neutral is always the easiest step
I always smile when watching these company office types. They have read the books and think they know, but in reality they lack road experience. It is cringe worthy to watch them drive. They use the clutch but are very rough. News flash: It is impossible to do a smooth split shift by double clutching. This is a 200 RPM split and is very fast. To double clutch a split is to shift rough. If you wanted to use the clutch you could get away with single clutching, but it is humorous to watch these office guys double clutching a split shift. Better stay in the office.
I am a logger, not a trucker. I am relaying this question for an 8yo Amish kid with health issues. We here in PA have 8 speed & a few 9 speed log trucks. I read somewhere in the PNW they use 13 & 18 speeds. His questions is what is the most powerful engine you can put in an 8 speed log truck?
Once you're smooth floating, your rev into gear will be the same seamless one-time rev that serves your transition to the next gear. Once single rev. Gear to gear. (No more two-revs). Rev, hold the rev in place, shift, and let the rev down, shift. Particularly 3rd-4th-5th-6th-7th-8th All those who know what I'm talking about, know what I'm talking about. Right, guys? 😁
It entirely depends on what speed you’re at AND your specific gearing. Ideally, you want the transmission & engine to be matched so you’re in the peak torque range BEFORE you enter the turn. That way you can accelerate through the turn/intersection if needed.
Same. I find double clutching (especially when feeding into the next gear) to be a distraction. I rarely use the pedal when upshifting, but in certain conditions I find it helps a lot. On even a slight downhill grade I don’t even use the pedal to start from a sign or light. It just feeds in when rolling.
I guess Im asking randomly but does anyone know a tool to get back into an instagram account..? I stupidly lost my account password. I love any assistance you can offer me
@Leighton Paxton Thanks for your reply. I got to the site through google and I'm waiting for the hacking stuff atm. I see it takes a while so I will reply here later when my account password hopefully is recovered.
You can split the gears without the clutch, but you`ll shock the driveline doing it. At the same time, excessive clutch use will wear the clutch out, despite the best of shifts. The Jamaican`s figured out a way to deal with it, instead of splitting and keeping the shifter in gear, or clutching, they take the shifter to neutral, switch the splitter, match the revs, put the shifter back into gear with perfectly matched revs.
Absolutely not.. Any shift ANY SHIFT!!! USE CLUTCH... IF you dont its shows yout lack of intelligence of what damage it does.. 40 yrs building them I know.
You obviously don't drive a semi 10 hours a day. Please don't sit in an air conditioned shop and think you are going to train a pro how to drive a truck. Stick with your day job. You are unqualified to teach professional driving.@@larryspicer3701
To be bluntly honest, a driver will never make it in trucking in a manual transmission tractor if one doesn't float the gears. Just like you have to be able to back, you have to drive the rig floating the gears. The old saying goes: If you can't back, you can't work, And if you can't float, you're a waste of money. (Which means you can't work).
@@ronspring7738 Yes. How much can you do? 68 hours a week continuously as the go-to-guy making the money for a company that only keeps guys who can pull off the impossible despite idiot dispatchers? As the one, or among the few, who keeps other drivers working who can't pull off the impossible, and evens up and defeats the losses? Unless you work for yourself. Can work as you want when you want how you want. Not having to drive it without fear of babying it. And have a tractor sitting in the driveway half the time. And maybe live off a spouse's income half the time, so one can play joe semi driver with a toy to double clutch every gear. Like all the independent operators I know. Who brag about everything I just described. If I ran a company, you wouldn't cut it for one week. I'd let you go the next Monday just so you had a week of pay to apply somewhere else.
After more than 30 yrs of floating gears, I've never broke a drive component. My current truck has over 900,000 miles on the original drive train. Clutch was changed at 800,000 only because rear main seal had to be changed. Didn't even have a single hot spot in the flywheel. Don't let this "expert" tell you it hurt the truck.
Can you teach me how to properly shift for my job interview tomorrow, how are all these people shifting so fast without grinding a gear, is there a guaranteed way to up/down shift ?
@@1Brooklyn2Many it's not something you learn overnight. It takes practice. Every truck shifts a little different. But basically you rev it just shy of the governor pull it to neutral while letting the rpms come back to idle, at the right rpms it'll fall into gear.
@@1Brooklyn2Manyyeah you have to learn to match the revs by ear. Learn to double clutch and get comfortable and get to know what rpm’s need to be then learn to float shift with no clutch. If the rpm is matched it will just go into gear
I’m over 40 years driving trucks. Started with 5 and 4s ,which needed double clutching,newer transmissions don’t if you listen to the engine. I don’t need a tachometer because I can hear and feel it. Hell, I drive standard transmission cars and trucks without using the clutch except for starting and stopping. No gear grinding, just listening to the engine.
