Double clutching described by Missouri: Is it accurate?

I floated the gears through the whole test. Examiner never said a word and never asked me to double clutch.

 

Dreamy, try to let go of that manual description of "let engine...." It's too much thinking. Patty said it right, if you're shifting into a higher gear, let the engine rpm drop to the next speed, usually 300-500 rpm. When you learn the tranny gear spacing, the shifts will mesh like a finger in a nose.

Shifting down is the same only the other way. You're going to a lower speed, so you'll have to pick up the engine rpm's a bit. Same thing, match the rpm's to the gear and the shift will just slide right in.

Upshift, say #3 to #4.
run engine rpm to 1,500 in 3rd gear. (any gear, really, the spacing might be slightly different)
release foot feed, tap the clutch lightly, move the lever into the neutral gate, tap clutch again, the rpm's should be around 1,100, slide the lever into 4th, and hit it! Same pattern 4th to 5th, so on.

Downshift, 4th to 3rd, say you're slowing for a turnin to the shipper. (4th and 3rd are pretty low gears, you won't see yourself using them much unless in traffic or a really steep hill)
You'll be slowing, so say at around 1,100rpm in 4th, lift off the foot feed, tap the clutch, start picking up the engine rpm's, move the shift lever in to the neutral gate, tap the clutch again, move shift lever into 3rd position. By now your engine rpm's should be around 1,500, more or less depending on conditions. It's a rythym, a nice, smooth sequence. Like SMD said, after a few hundred shifts, it'll be second nature. Best!

Try not to get tense (ever) but if you find yourself tense, you'll notice you're holding your breath. Let yourself breathe easy a few times, nice, smooth cleansing breaths. (LaMaze) It really makes a difference.

 

The real key is to listen to the motor. Also when double clutching the school should have given you a RPM guide for upshifting and downshifting. In up shifting you hab have to quickly tap the accelerator to get it to a higher hear only a fraction of a second and on downshifting wait until you THINK the truck is going to cut off and downshift.

I went to the MVD in Albuquerque, $150 per attempt. When the Examiner showed up and I started my pre-trip, during the sequence I just asked him about it. He was a professional guy, said "shift like you know what you're doing and you'll be fine." So I used the clutch starts and stops, floated mid-range, no problem. Communication, it's the newest fad.

 

I agree on the communication which I did when testing out.Far as floating here you can't do that and even back then I couldn't have floated because I didn't know how.Now that's all I do is float.

 

^^^^THIS!

If your timing is right it's not something you actively have to worry about. I just checked the manual here in VA and it's the exact same wording. Stupid.

 

Here there's 4 things that'll get you an AF,shifting on tracks,coasting more then a trailer length.floating ,and running over curbs.
