Double-Clutching
Truck transmissions don't have synchromesh gears which allow you to shift even if the input and output shafts are rotating at a different speed. For a truck, you need to match speed with what the engine and wheels are doing. Shifting for truckers is a two-step process. Hit the clutch and put the transmission in neutral. You then quickly tap the accelerator to match engine revs with what the wheels are doing, hit the clutch and put it in gear. You can use this method to see how smoothly you are shifting normally, and helps you learn how to rev match. The benefits of rev matching include smoother transitions between gears, especially on downshifts as well as reducing the wear and tear on the synchromesh gears themselves. |

But is not a good racing technique right? Doesnt make you drive any faster like they claim in the first Fast And Furious.

F&F is a bunch of bullshit. doubleclutching slows u down if anyting. If you're at the track, n ur downshifting to reduce ur speed for the next apex, so ur goin from like 3rd to 1st, thats when u NEED to double clutch to put the gears in sync. Any other time, you should "grannyshift"

i double clutch when i downshift to second..
my syncro is going and i grind if I dont. slows you down, but saves your gears |
Double clutching at the track? Ummmm....no.
You basically never double clutch in a transmission that has synchronized gears....especially while racing. You might be thinking of heel-toe which is completely different. You still only press the clutch in once. Some older manual truck trans don't have a synchronized 1st or reverse gear, which requires you to double clutch. You have to or you cannot get the trans to go into gear. But they stopped making those transmissions in the 70's. Everything made in the last 20 years in cars and light trucks has a fully synchronized trans. Even my ancient camaro has fully syncrhonized trans. And you shouldn't be using engine braking by downshifting to reduce speed. Thats what your brakes are for...unless you want to take the slow way around the track. |
