You obviously understand engine speed then. Trucks that schools use are turned way down so they rev real slow as well, this doesnt help down shifting in my opinion.
Also, watch a video on youtube about progressive shifting. It might actually help you.
Trouble double clutching smoothly?

The other thing is getting used to really smashing the throttle down and waiting what seems like forever vs my car for the rpms to come up on the rev match. Truck engines are a different animal than the aluminum flywheel mated DOHC v8 in my Mustang! I'd never ride the throttle as long or as hard in my car so I've had to learn to ignore the "OVER REV!!!" warning buzzers going off in my head.
There were important things that carried over though. Two of them I found helpful was understanding the "standard - H" shift pattern. Our instructors have spent a good bit of time explaining the "soft wall" vs "hard wall" of the shifter b/c people who are new to standard shift have trouble finding second and third gear. A lot of them think you have to move the shifter over from 1st to second and overshoot ending up in fourth. I didn't really have that problem b/c I already know the shifter will fall into the middle of the H between and second and third once you pull it from first ( or any other gear for that matter ) and just let it move to neutral naturally. The just push straight up or down to hit the middle gears.
The other thing I found that was an advantage to already knowing how standard shift works was understanding every clutch has an engagement point and even when you get into a knew truck it's a pretty quick muscle memory exercise to figure out that pick up point and smooth out modulating the clutch especially on take offs. I got a lot of complements from our instructors and other class members for having the smoothest clutch engagement and take offs even when we were practicing backing maneuvers. I tried to explain how figuring out the pick up point of any truck your in and managing momentum is to your advantage. Some people got it but most of them didn't. I guess it's just a practice and familiarity thing but I think it is something that adapts pretty readily from driving a standard shift car.

If you can float just make it look like you are using the clutch. That's actually what I do all the time. I push the clutch in like 1/2" inch so I don't think it's doing anything but it looks like I'm using it lol.

Just do what you can driver! You'll never double shift once you're on your own That clutch will be used when you stop and when you first start to roll that's it.
Take as much time as you need to get yourself comfortable in that seat. Mirrors seat steering wheel.MYSTYKRACER, FlaSwampRat and D.Tibbitt Thank this. -
The only time you need a clutch is when you are taking off. Do what you have to in order to pass the class. Once you get out on your own forget all that stupidity about double clutching, it's a waste of time and unnecessary.

I don't worry about 4th gear or any gear out here. Whatever gear I am in vs say a Jersey traffic light change is what I gots. Maybe she lugs maybe she has horsies, but whatever gear at that moment it will be the gear to keep moving or stop.
The one rule they used to teach without so much beating a dead horse is always keep power to the wheels. Essentially stay in gear. Particularly crossing railroad which was quite a lot in Baltimore.
Big rigs are not cars. Cars synchronize to the engine and if there is room in the transmission gear you want it's good.
Don;t worry about waiting on the engine. You are working too intensely. Trucking is not in a hurry, and at the same time you are. (Appointments)
The Test is just a process. Once out and into the wilds around the USA you will be free to work all that out.
Its been years since I touched a big rig, but the manual will need a hour or few to get good again. Just need to know the torque RPM and the High Horse RPM. It wont be pretty for about 40 miles to half a day or two.MYSTYKRACER and D.Tibbitt Thank this. -
Obviously you are paying attention. In a day or two things will cluck and you will upshift like a vet 90% of the time. That's about when you notice you have more problems downshifting. That's normal. You seem to be doing better quickly. A month from now you only be nervous on worst-case scenarios until you see enough of them to know you can ace them. My problem was learning to ignore the pressure I was feeling from the 4-wheelers behind me, who are always in a hurry. Ignore them.
MYSTYKRACER Thanks this.
