Using The Throttle While Letting Out On The Clutch

So my wifes at cdl school same one i went to and i was taught and practiced to release the clutch on initial take off with no accelerator and let the governor do the work and they are teaching her to use the peddle and lots of them including her have had stalling issues in my experience that is because you didnt let the truck do the work any input on that i feel like they are doing her and the class an injustice idk maybe im wrong but its the way i learned and ive nailed it my whole driving career

I was taught the same as you were and use it daily for the last 6 years and never had an issue. If it’s not the correct way, it sure works well.

I used the accelerator while letting the clutch out with my trainer. Once. The verbal lashing I received taught me the folly of that.

I have only driven an Auto while driving OTR but when I first started driving 30 years ago it was pulling grain trailers out of the field so the thought of not using the accelerator before releasing the clutch never occurred to me. It would work empty or on flat pavement but that is about it,

I learned how to shift on a whiteboard because I didn't understand it in practice. The way it was explained to me, speed and RPM have to match the gear. This varies truck to truck. In the truck I used it was the usual system

1+5=6 15 MPH is 6th gear 2+5=7 25 MPH is 7th gear

Add to that using RPM. You want 1000 RPM for each gear after idling. So if the truck idles at 500 RPM 6th gear would be 1,000 RPM, 7th would be 1,100, 8th would be 1,200 etc.

When down shifting you need to drop the speed to the lower end of the window. So if I'm going from 8th to 7th I want the speed at 20 instead of 25. Because I'm slowing down the RPMs drop so I have to give it a bump. I bump the accelerator while in neutral so the RPM jumps to 1,100.

Down shifting is clutch, bump, clutch Up shifting is clutch clutch

This may sound confusing, but in practice it worked well for me and my shifting has improved drastically in a short amount of time. I've never driven a manual and 2 weeks ago, I couldn't go from 2 to 3 without stalling out.

It's an old habit that comes from driving a car with a stick. You can "ease out" the clutch on a car without giving it gas - but it doesn't quite work correctly that way.

Going into a truck - I "thought" it was going to be easy, being I had driven a stick my whole life. One lap around the track - and I was asking myself "WTF was I thinking?"

Class 8 Trucks have enough "ooomph" in torque and HP, to get the rig moving without fuel. "Feathering" the clutch usually results in a jerky launch, rapid wear on the clutch, and having to get out of your launch gear almost as soon as you get the clutch full released.

Took me a minute to get used to - I started floating gears almost immediately - and FAILED my first road test: because I had forgotten how to double-clutch.

Thanks i thought i was crazy this school sucks that she is attending i hope she gets her license so i can actually teach her how to drive a truck properly

You will never need to give it any throttle while letting out the clutch in a big rig, assuming you're in a low enough gear. Even fully grossed out at 80,000 pounds starting on a hill the truck will take off just fine in 1st gear without touching the throttle. In fact, you're not supposed to give it any throttle while you're letting out on the clutch. You will burn up the clutch rather quickly that way, or snap a driveshaft if it locks up too quickly.

Yea that was my sentiments exactly this is why im baffled as to the school training her to use the throttle so im training her on the weekends the right way

I have done it both ways, and stalled it both ways. For me, I guess it depends on the particular situation. Right or wrong, I will continue to do it both ways
