Same here. I love my manuals but never understood how to shift a semi transmission until I watched this video! He explained it perfectly! Basically just 1-4 direct and overdrive which is 8 gears, then split to high side, then 5-8 direct and overdrive, which makes 16 gears, and low low direct and overdrive which makes 18 gears! Now that I understand it, it’s simple really

thank you for the video! is it a problem if i use the clucth while i'm shifting an 18 speed transmission?

@@eddyboisrond7259 not at all, double clutching was the norm before gearbox syncros! had to match that engine speed to your actual speed via a combination of throttle modulation/“floating gears” like demonstrated here, or you’d be grindin every gear you try to grab! 😁

Ikr

i second this!! good job bro

It’s WAY easier than the terminology would make it seem. lol.

Your videos show that you are a true professional. Ive been told that if you can practice with the same rig day in and day out that that helps immensly. Thank you for responding to my comment.

Exactly i had no idea about it till now

Agreed

It takes practice but you can do it. There are lots of driving schools that can help you get your license.

Dr Deacon; 18 speed is same as 13 RTO or Direct Fuller tranny. EXCEPT you can split, the lower 5 base/stick gears, with splitter. Not hard to understand. VERY GOOD in the oilfields, used to work/drive in them, with Power Puppy . (mack)

@@petersack5074 could have done with the regular terminology, crawler (not low, low low or low low low), Range change (low range 1-4 high range 5-8) and splitter (high & low in each gear). In reality doubtful that there are 18 individual overall ratios as there can be duplication). In UK we'd use 3 low pulling away on flat, splits in high range only and probably just on 7th & 8th. Crawler can be used on very steep hill starts.

Most guys don't need the 18 speeds!!

Nope. I drive 18 speeds and sometimes split all the way up if I'm climbing a hill with Super B Trains. Each gear is different all the way up. there is no duplication at all. Now after saying all this, the 15 speed does indeed have duplication. What it is is simply is three ranges, and no splitter at all. The blue button on the side looks like a splitter, but it's not. It has three positions for three ranges. If you wanted to shift sequentially in a muddy bush you might start in deep reduction, you'd go 1,2,3 and then mid range (they call low) back to 1,2,3,4,5 and then high range, and then 1,2,3,4,5. It's just that easy. Most guys shift them like a ten speed, but they were skipping low to start out and they were going through clutches like crazy. With a 15 speed with a load you need to start in low midrange, however if you're in mud, you might choose to go into deep reduction to get started. @@hitop2365

If you've never driven heavy trucks, that simulator will trick you. You might not get it into 2nd gear, never mind 18th. I'm a driver trainer, and it's funny watching green drivers come in and get humbled real quick. It's not hard for us, but you guys take a while to grasp it. You see them double clutching like crazy and it just grinds, and then we shift it with two fingers and no clutch. It's called rev matching. You don't learn it in a day.

actual facts

Facts

How did it go ?

It's so much easier without clutching, once you get the hang of it. Way easier than the synchronized transmissions we had in Europe that require clutching. But no more manuals in European trucks anymore.

How long did you drive for? Thank you for your service!

If you can drive a 9 speed, you can drive an 18 speed. It’s just a 9 speed with an overdrive box on the back of the transmission.

I learned on a B Model twin stick 3x5 away back in 1974. Love those old macks. New ones.....not so much.

Gary Chandler Hello how are you doing today?

@@wandajohnson7492 Um....married? But hello backatcha!

@@garychandler4296 am single and you??

@@wandajohnson7492 I meant I'M married...67...ex-bodybuilder...remodeler. But you're a cutie!

@@garychandler4296 Really where are You from?

Nothing to it, once you drive one you’ll never forget. I learned in an old Mack with two sticks, 5 spd main, 3 speed compound, same as a 15 with a splitter except you get to row tow sticks lol and double clutching was needed quite a bit downshifting. A man needed a lunch break by the time he hit top gear in that ol,girl.

Sorry about the rambling comment, but yes, your right, you shift through the pattern, flip the range finder and go right back through the same pattern. Good luck

I've driven the Mack B model with 5 X 3 and I did not use the clutch much. I haven't seen a B in a long time.@@deborahchesser7375

@@SternDrive I’ve driven a Tri-Plex too I like them they shift way easier than the quad box. I could fly through the gears with that TP. I wish I had a bunch of old trucks to play with and make some cool sounds.

@@SternDrive you’d love the DM800 I leaned in, what a beast. #65,000 lb bogies

Feel free to ask. I’m already planning another video. 😁👍🏻

@@Truckinlife I will. Trust me.

learned it well didnt you?

@@lindabingham394 kind of like being thrown in the deep end of a pool to learn how to swim.

I always use the splitter in high range. It's just easier on the engine, and your fuel economy, because you don't need to rev it as high. 200 RPM splits are great for saving fuel. You are always in the sweet zone. Use your splitter. It's there for a very good reason. Bobtailing? OK, then you can skip it.

Omar Peart Hi how are you doing today?

@@wandajohnson7492 im great

@@anthonyp3360 am also good here dear where are you from ?

@@wandajohnson7492 Jamaica

I agree. I watch them all the time. lol

I know what you mean. I used to drive an Eaton twin-split and thought it was great, but much prefer my full auto scanny with hill start and all the rest.

I told my boss that if he gives me an auto shift, I will quit. I have never owned a car with an automatic. I hate them. Watch my video "Shift a 6 speed like a pro" and you'll see why. An 18 speed is a piece of cake if you know what your doing. If not, well I can see why you would not like it.

@@SternDrive You can still use I-Shift manually if you like :)
