Struggling Double Clutch Downshift
Topic 24991 | Page 2
I greatly appreciate all the input. I watched some videos and thought about what mistakes I made. #1 thing that stands out to me is that I can easily up shift ,and it hit me that I haven't realized that the speeds of the transmission is lower speeds than that of pick up truck. Meaning I can be 25 mph and in 5th gear where as a pick up its totally different and I also realized I haven't been double clutching like going up. I been trying to hold clutch and down shift. Gotta get my **** together. I know BETTER.. All of you are very much appreciated. Will update my progress by Monday as I school tomorrow and work Saturday then practice with buddy Sunday and test late next week. Be safe friends and truck on.
Double Clutch:
To engage and then disengage the clutch twice for every gear change.
When double clutching you will push in the clutch, take the gearshift out of gear, release the clutch, press the clutch in again, shift the gearshift into the next gear, then release the clutch.
This is done on standard transmissions which do not have synchronizers in them, like those found in almost all Class A trucks.
Double Clutching:
To engage and then disengage the clutch twice for every gear change.
When double clutching you will push in the clutch, take the gearshift out of gear, release the clutch, press the clutch in again, shift the gearshift into the next gear, then release the clutch.

AGAIN PROS PLEASE CHIME IN BUT...
Our instructor gave us this trick... add the speed digits to get the right gear:
25... 2 + 5 = 7 (th gear)
35... 3 + 5 = 8th
45 = 9th
May vary somewhat but generally pretty close! Way different than non-CMV's.
I also tended to push clutch way to deeply... almost to clutch brake or floor. Thought I was supposed to hold it to floor when stopped at a light. Trainer floats so his clutch is barely used. Was killing me! Told me to just hold down enough to disengage when at a light. Didn't get to practice that much.
Sometimes it's just do it differently! If going too deep... don't go nearly as deep. You will find sweet spot! If holding it in FOCUS on the double. No matter what double clutch! Then work on fine tuning next item. You gotta get the big stuff right. Finesse will come! Make sure you are holding knob firmly - I wasn't. Know the pattern. Feel where the gates are (every chance you get when in the truck and not in traffic, etc..).
Just throwing out a few things that helped me. I am a novice too but until you get more inputs from the pros here some of this might help.
Also, unless on a steep hill with a heavy load... fuel after truck is moving... not when letting out the clutch! Also a CMV difference!
You got this!
