Struggling in double clutch in lower gears.

Done trying to help people out with this.
Watch YouTube videos.

 

Try starting in first and shifting around 1300.

“But Six, my instructor wants me to start in 2nd...”

Tell him that you are just curious about first gear.

Luck in battle.

 

1100 works smoothly because you're driving an empty truck. Won't work loaded.

 

Your instructor is an idiot. It won't help to practice in a car. They are completely different. If 1100 rpm works well then do that. As noted it will be different when loaded but for now just do what you gotta do. If your instructor complains you are not doing it at 1500 then point out that they are not either. Best wishes to you!

 

Ugh, ok, the trucker in me just can't resist. You aren't shifting fast enough in low range. No, it won't help at all practicing on a car, totally different. Cars have synchros that mesh the gears for you and 2-3000 rpms difference between gears. Remember, the difference in rpms between gears in low range is real close, maybe 3-400 rpms, and by waiting the 2 seconds, you're missing that sweet spot. Generally, in low range, you don't need the clutch at all, let up on the throttle, ( the clutch slightly depressed may help at this point) pull it out of the one gear, by the time you do that, slight pause in neutral, maybe, it should go right in the next, it's a very close ratio. If you "ride" the next gear, not clash it, you'll feel when it will go in, gotta be quick. Later on in the gear changing, (high range) yes, waiting the 2 seconds may apply as the ratios get farther apart. Hope that helps, and we save yet another transmission from destruction,,,

 

Ok, this trainer is wrong. He is essentially teaching you how to progressive shift. That you can learn later. Know we have no idea what engine, but I would say for the purpose of learning gently take it up to 1800rpm or 1900rpm. Then shift and try to have it back in gear at 1500rpm. You are above max torque in most engines and it will shift smoother. Your ears will aid you more than your eyes and gauges. Plus it comes down to your experience in that particular truck. Nice and steady when you go back into gear, gentle. If you hear a slight grind go back to N and clutch it again. No one is perfect. I double clutch all the time. Cant tell you how many time you hit a pot hole while you have the clutch in and shifter in N. Just regroup and try again. You have to force your arm not to be ridged, more lazy and fluid like.

 

Id fire that guy if he drove my truck. Yea he is showing you the the idea, but he has a worn out trans and is still floating it. You hear the detents click in the trans? This is a poor example of proper double clutching. To ruff, needs to be fluid like.

 

1,800 or 1,900? In low range? I don't wind my engine, DDEC2 to that kind of rpm at anytime!

In low range, low rpms only unless heavy uphill.
