  • It is, but while it may save wear on the clutch, it's probably a bit savage on the rest of the transmission. You would shift almost the same way as double clutching in a crash box, but obviously you don't use the clutch... It's best to work the throttle so that there is little to no load on the gears (either not accelerating or not decelerating - basically crusing or coasting). If there is no load on the gears, they should disengage easily. Now you blip the throttle to increase engine revs. Gently but firmly (in other words, don't smash the thing into gear) push the gear lever towards the gear you want to go into. When engine revs match gearbox revs, it should just slide into gear. There may be a jolt as the load is suddenly applied to the transmission, but effectively you have changed gears without using the clutch. It's pretty pointless, but you can do the same in a synchronised gearbox as well.
  • Yes. It is. Regardless of synchronized or unsynchronized, sometimes the synchronizers wear out. Every manual transmission can be shifted into the appropriate gear based on three things: Road speed, Transmission Speed and the R.P.M.'s of the engine. When all three of theses match, the specific gear for that match will allow gear engagement can take place within the manual transmission. In most vehicles, but not all, the R.P.M. span between each gear is 500 R.P.M.'s of the engine's revolution. When down shifting without a clutch, the engine R.P.M.'s will need to increase by 500 revolutions per minute to ensure that the next lower gear is accessible (matched). When upshifting, the engine R.P.M.'s need to decrease by 500 to ensure engagement. You must take into consideration that the 500 R.P.M. , or any R.P.M. span, will be accurate ONLY when on flat terrain. A gross increase or decrease is not accounted for and will significantly alter all three factors needed to match transmission gear speed with road speed and R.P.M. speed. Practice will improve the drivers ability to make the necessary adjustments in his/her timing, with regard to road speed increases or decreases and transmission speed. However, it is likely that practicing these skills will undoubtedly destroy the transmission from excessive wear by the time this shifting skill is perfected. Synchronizers are exactly that. They attempt to make up for the differences in losses or gains in each of those three factors so that the operator can become lax in those skills. Technically, then, a clutch isn't necessary, except to disengage torque from the transmission for stopping and starting the motion of a vehicle.
  • It is possible to shift with out the aid of the clutch. It is known as "floating gears". Working in the industry I have not seen it cause any more damage to the transmission than normal wear, as long as you are not grinding the gears every time you shift. It is a basis of matching engine speed to drivetrain speed. The worst thing you could do is to push the clutch all the way to the floor, as this engages the clutch brake. Clutch brakes are only useful for starting out, getting the truck into gear. Pushing the clutch all the way to the floor going down the road could result in breaking the tangs off the clutch break, rendering it useless.
  • Yes it is possible, if you don't mind whiplash, spilled loads, broken gearshifts, and countless other tyoes of damage to your truck. The manufacturers hung that pedal under the dash for a reason, and if you will read your owner's manual, you will know why. Sure, it can be done, but if you are paying the repair bills, you will insist that the clutch be used.
  • yes it is possible but i dont recommend it. my grandpa dragraced for many years, he rarely used the clutch other than at the line and when he parked it thats the only time i see it being usefull.
  • Are you kidding? I only use the clutch to start, after that I shift without the clutch all the time. It only takes a bit of practice and concentration to get it down pat. Transmissions, clutches and drive lines last a lot longer this way
