Mar 17, 2012 - You have to learn to DBL clutch in most states to pass your test! keep in mind,as you get good you will develop your own way to shift,don't go by what other people do..just a tip if you are learning and going for your test or training.
Feb 27, 2012 - Yes there is at a particular rev, for example,
1200 rpm = 20 km/h = 4th gear (top gear bottome box)
1200 rpm = 30 km/h = 5ht gear (bottom gear top box)
1200 rpm = 40 km/h = 6th gear
You can work this out by taking your truck up to 1200 rpm in each and just before shifting to a higher gear note the speed you are doing, so you have "speed = gear = rpm"
Feb 10, 2012 - don,t disagree because he explain it very well you just was not listening . It can be done but by pro drivers only who don,t grind gear when they don,t used the clutch . I have a friend who owned his own truck an only used clutch to start and stop nothing else not even hills . an never change a clutch in the life of his truck .
Feb 6, 2012 - he is taking shit when he says if you don't use clutch you'll kill the transmission.i do it every day ,no damage at all,thank you 1parre.
Oct 27, 2011 - @edwardzimmerman:
Neither! It is best to give an example: Say you're accelerating and tach reaches 1800rpm.
If the next gear up at that speed is 1500rpm you clutch, use accelerator to give the engine 1500rpm and then release the clutch at that rpm. Thus there will be no kangaroo jump at the clutch release and accordingly no stress shock for the driveline to handle. Anyone with a stick-shift do this instinctively. With a big-rig it turns important because the forces at play are so big...
Oct 19, 2011 - What does he mean by match the RPM to road speed? Gauges in same position (ie both at 11 o'clock) or is there a particular speed for every gear that needs to be memorised?
Oct 18, 2011 - ill be honest, i disagree with part of what he says. my dad shifts most gears without using the clutch, and he has gotten full use out of the transmission, no premature failures. his clutch lasts twice as long, he only uses it when downshifting up a hill. the key is not to force the transmission, you use the foot feed, if it starts grinding raise or lower your rpm till it slides in nice. when you slam it, you wreck stuff. im suprised he didnt mention wrecking the clutch break.
May 16, 2011 - @Fantafare Oh too true I learned to drive a truck on a 12 Speed Crash Box and Split rear axle and if you made a mistake then you found out real fast.
Take the load off and allow the gear to simply slide into the next with no load ie roll the revs down and the Box will just slot in 'eh
Dec 5, 2010 - because just like the cruise control , an automatic transmission can not see the upcoming hill and only reacts when it's hitting the slope. Nothing beats the human brain.
Jun 17, 2010 - thanks, this cleared stuff up. Not sure about the non synced gearboxes tho, seems old. And even with a fully synced it's still possible to fuck up. missing gears, clutching too fast... specially when going hi to lo, miss one and you are free wheeling 40 tons. all bad for the tranny no matter what.
Jun 11, 2010 - These transmissions do not have any sycros on the main box just the aux transmission, thats why you have to match speeds when you are shifting
Apr 3, 2010 - Thanks for this video.
I'm about to learn the art of truck driving, so am really worried about all the shift patterns, Hi/Lo and Spitters... This video has cleared up some of the confusion. Thanks.

Mar 29, 2010 - that was very informative... i guess i am guilty of harming a tranny or two or three and i didnt even know it.
