    I'm acing this hardcore school I'm going to with one exception. I can fully control the truck, do not fear turns, backing in, proper use of mirrors, etc. Control of the truck almost seems second nature to me. I can turn it on a dime etc. However, my one weakness. SHIFTING. We went out on the open road the first time yesterday in a ten speed and man I was grinding the gears. I cannot get the double clutch rhythm down. I keep tending to stomp the clutch down too hard and too far and by the time I go into gear RPM's have dropped and I grind. Is double clutching really absolutely needed? Downshifting....Forget about it. Per the instructor....Holding the RPMS at exact sweet spot and then clutching and sliding the gear in. Problem is, I let up off the throttle when it comes time to clutch and slide it in. It's just a natural thing from driving a stick for year.

    Instructor is awesome. Great guy, but #### he will throw 3-5 things at you once while you're just trying to feel that rhythm. "watch your tachometer, where are your RPMS', clutch in, neutral, clutch out, clutch in, go to gear, watch the road, where are your RPMS's" etc, etc.

    I'm just looking for some way to get this rhythm down and get it down quick. I would be beyond upset if I ace this school and fail for not being able to find a proper shifting rhythm. They will not allow us to #### per short cuts, skipping, etc. We have to learn it by the book.

    My relative who is out there driving for years, said I probably can drive good enough to go in and take the CDL at the DMV as they really don't care as long as you go through the gears. Whatever, I just want some techniques so I can get this crap figured out soon!!

    Thanks!!

    To me, that double clutching is the main problem when learning to shift. Once you get your license you can float shift and it alot easier. I dont have any tips on getting the hang of double clutching but someone else will be along who does - Good Luck !

    Plant your heel. Then point your toe. Don’t use your leg to move the pedal. You only need to move it enough to brake torque.

    Unless it's an International with a hydraulic clutch,lol.I don't care what you do, especially if it's weak, it will hang up in gear no matter what you do. A dead giveaway is If it won't go into gear If you're waiting at a light.

    I hope you are in boots with at least a inch on the heel. You will find as Espressolane stated you plant that foot and the clutch is right there enough to cut power but never all the way down. (Unless waiting for a green light then all the way down to brake the transmission and get your starting gear)

    At some point your tractor runs out of the gear you are in. You have to upshift with the new gear already adding power before your RPM's drop too low. It's going to be around 1300 give or take depending on your engine. You have to be in the next gear up by then.

    Same with down shift when your tractor refuses to pull you come out of that gear and while in nuetral slap your engine to 1600 or higher your next gear down will be ready for you more or less.

    It is never like a car. You are driving a non syncronized transmission. Cars are built to take care of that for you. But big trucks are not. YOU are the one that has to match it.

    Totally understand all that you said, 100%. Heard all those same things from the instructor. The tractor a machine, it's not going to do what you want, you have to give it what it wants. etc. etc. The problem is doing it. LOL. I will try leaving my heal on the floor and just using my upper foot to engage the clutch. I was putting the center of my foot on the clutch and mashing it down. You're mind tells you, you have about 1 second to clutch in and out twice, go fro gear to neutral and back to gear, clutching twice and all that in perfect rhythm in one second. Not an easy feat when you're in a tractor driving down the road trying to pay attention to all that at the same time as well. Too bad there isn;t a shifting simulator out there for tractors. I'll bet you'd be rich if you invented one.

    There is already in the industry Shifting Simulators. We started having them back in the 90's You could configure them with settings for a thousand different combinations. Why it was not widespread was probably because of the money it cost. You could probably buy one for yourself and play with it at home. HA...

    As far as I know the point of double clutching is to slow you down and most likely it isn't that you're too slow but too fast.

    Most new people go way, way to deep on the clutch. The secret is the nudge. You just want to nudge it. It takes time to develop smooth shifting.

    Smooth is fast. You become smooth by going slow at first.

    Shift at 1500 rpm. Just nudge the clutch.

    When the transmission rpm matches the rpm, the gears will feel like they have stopped spinning. You will feel the gears slow and stop. At that moment, nudge the stick like @Dave_in_AZ said. It will drop into gear.

    Don’t look, FEEL. The engine makes a particular sound, a rhythm. The double clutching is a rhythm. Once you get the rhythm down, it becomes easy. You don’t learn a rhythm with your eyes, it’s your ears.
