What happens here

Darrell explains the use of a 'splitter' in the manual transmission, which doubles the number of available gears. He demonstrates how the 'high/low' selector on the gear shift works, splitting each main gear into two, and mentions that this allows for up to 18 gears in total. This technique is essential for optimal performance and fuel efficiency, especially when hauling heavy loads or navigating challenging terrain. He explains that knowing how to effectively use all these gears, including skipping some when appropriate, is key to being a skilled driver.

Goal: Explain the operation of a manual transmission's splitter and gear shifting.

What they say

Hide

the the pivot point. Well, they wind up holding it down here to shift cuz it's so tall. But what is the sequence if you're starting from a stop? Are you like moving and flipping a switch? Like what do you what is >> Well, you you got to go you got a high and a low. Here for low side and high side and then we got an overdrive button on the side here. This is a 13-speed. All of them this is how this button here They got low side and high side. You got a traditional pattern here. First, second, third, fourth, fifth. Well, about that Well, the 10-speed you come back over here and start all over. But with 13 18 you go you don't use this little hole. Oh. So, you go through it all, flip the button, and then go through it all again? Uh-huh. But how do you get to 18? You got to do that three times? >> Well, 18 is the same transmission as the 13 only you 18 you got five in the basement. But you can split the bottom five. You can't split the bottom five with 13 or 10. What reason would you need to do that? What situation? Uh I like an 18 because if you're really in a hard pull, it's easy on your clutch. Hit the button. You know what You know it's hard on the equipment. I don't I don't split all of them in 18. I only I only split twice, two or maybe three. Oh. I got some It's got some nice torque. It's nice power. You don't need to split them all the way. It doesn't feel like this thing's really laboring to move itself Yeah. Yeah, it don't. It's just You could tell me this thing was unloaded and I'd believe you. Is a conventional truck quieter cuz you don't have the engine right in there? The new trucks are quieter cuz they've got a They insulate them. The new trucks are built for driver comfort. They're a lot They are a lot quieter. The new trucks are a lot quieter than the old trucks because they've got more insulation and more padding and more foam and and the engineers have really done their their work and and built them a lot quieter.
