Double clutching Help!!!!!

I am currently in school and today was my first day on the road. I did terrible at double clutching. I got it 1 time and that was it. I was wondering if anybody out there had any pointers regarding double clutching? On the bright side I kept it straight, didn't cut my turns short and stopped at all stop signs.

 

I'm in my last week of a CDL training program. It took me about three weeks of driving to get it down. What finally helped make it sink in was going to Dollar Tree and buying an extra plunger. I spent a few hours over the course of the week practicing shifting while sitting in a chair at home. Move your foot as if it was on the clutch, and move the plunger as if it were the stick. When practicing downshifting, simulate revving the engine with your right foot. If you understand what is supposed to happen and when, it's all a matter of getting the rhythm down.

Last part, don't sweat it. Instructors shouldn't be expecting perfection on the first day, and you will get there if you remain calm and coachable. Good luck!

 

I start Monday cdl school, i will be out in the yard the first day cause i have my permit, wich i will be working Pre trip and air break test, the double clutch thing is something just have to get used to i reckon listen to sound of engine and rpms and practice hope i can learn it pretty fast only time will tell.

 

Thanks for the help. I grabbed a plunger from the front deask and brought it back to my room. I am comfortable upshifting, but my problem is going to be downshifting. I payed way to much attention to the TACH. I need to slow it down in my head. I will just do what they tell me. Thanks again.

 

Practice makes perfect. You'll get it.

 

PRACTICE PRACTICE PRACTICE. Took me awhile to learn to double clutch. Comes down to engine and road speed. The truck will only shift when it wants to. While downshifting make sure you rev the engine up far enough. It will never go into gear until the rpms and speed reach the right spot.

 

Relax and slow down. Don't force it.

 

ItIts your first day...just keep practicing...in a couple of days you'll be laughing how hard you thought it was at first. Good luck

 

In three months, you will look back on this double clutching problem and laugh.

Remember, don't deep clutch. Push the clutch pedal down about as far as the brake pedal when making your shifts. Upshift on the low side around 1300 rpm, and 1500 on the high side. Clutch-neutral, clutch-gear. Downshifting: Let your tach fall to 1000, clutch-neutral, rev to 1500, clutch gear. Let the tach fall to 800 if you want to skip shift down.

Gear rules of thumb:

In a 9 speed, divide the road speed by 5 to determine the gear you need to be in.

In a 10 speed:
15 MPH= 6th
25 MPH= 7th
35 MPH= 8th
45 MPH= 9th
55 MPH= 10th

If you're moving too fast for that gear, you won't be able to downshift to it.

This doesn't apply to every truck and every situation. I've driven 9 speeds that will do 60 MPH in 7th gear pulling over 70K. It depends on the differential.
