How come when the video shows you shifting up, ( further back cam shot) the tack says around 2,300 rpm, But when you show the other cam, (closer cam), (aswell as verbally instruct to do so) the tack is showing 1,500 rpm - 1,300 rpm??

@deadhomie93 I higly doubt I hit 2300... however, I may have been pulling a hill so it may have been higher. The loads I was pulling up0 11% grades were 160,000 lbs so it would take more

So when do you single clutch and when do you double clutch???

[seansuth]

@Marsbonfire007 You only sigle when moving the side button

[lvachon]

Wow, you only use the clutch downhill, and rev-match the rest of the time! That's shockingly impressive to this average commuter. That clutch must last forever, what about the synchros though?

[seansuth]

@lvachon There isn't a syncro on rigs. That's why you need to use the double clutch system

@dlawson435 Rookie huh? Doubt it. It's called a LEARNING video. You try to not look at the tach durring a CDL test and FAIL.

@fluffman93312 Your right, that's who this video is for. CONGRATS

@MatthewJames1985 Sorry, been a long day.

[MatthewJames1985]

good i was not making fun of you I think you are actually a good teacher, so keep up the good work, sorry if I was being disrespetful in any way

[MatthewJames1985]

@seansuth Lol I never look at the tach and always shift smoothe listen to the engine then you will see try going from certified mechanic to truck driver then you will see

[seansuth]

@doctorfeelucky The very basics yes, double clutching makes it different
