reasons why the truck grind and jerks when trying to shift gears

Through.

Threw is entirely different.

 

Are you double clutching?

Remember to only press the pedal part way down.

 

Here's a good video on shifting, It might help. http://youtu.be/L1KFOK-CkMA

 

you may be pushing the clutch down too far, i had that problem, HAD!

 

other then to stop. why are you using the clutch in the first place?

 

Please don't be one of those people. You are required to use the clutch in cdl school. Not using it does NOT mean your cooler, awesome, studlier or better looking. It simply means you have more experience. Instead of being a condescending jag, give some advice so that others may learn from your experience.

 

i would say the same thing coordination danielson...

 

the best answer I have read in this whole thread wins the cookie. New trucks are designed to progressively shift. The number 100 rpm is also correct. Each shift should happen at 100 rpm higher than the last. The engine and transmission should be in sync then, so you dont have to put the peddle to the floor. The clutch peddle only has to move about an inch to shift when you are using the clutch, all the way to the floor engages the clutch brake and is designed to stop the transmission from turning when you are in neutral so you can get the darn thing into gear without difficulty. When you just lightly touch the clutch peddle when you have your jake on it eliminates the jake without engaging the clutch.

 

i posted this in another thread cool little trick when your in the high side add your speed numbers together and thats the gear. example running 15mph is 1+5=6gear all the way up to 45mph 4+5=9gear. i still catch myself looking a speedo after i change a gear just to see were it is lol. alot of it is just feathering the fuel pedal with light pressure on the shifter and will go were its suppost to.

 

Dont use the clutch and keep your rpm low, dont wind it up. These new motors dont need it. the clutch is for stopping and starting.
