<VV> clutchless shifting

[Tom Berg]

Clutchless shifting (aka "float shifting") works on heavy truck transmissions because there are no synchronizers in the gearbox. Experienced drivers can do it by matching engine revs with the correct gear for the road speed at the moment. It's easily screwed up and can damage various parts in the transmission. Wise drivers double clutch to unload the transmission while changing gears.
 
Cars and light- and medium-duty trucks have synchromesh transmissions (if they're not automatics, which most vehicles today are). When you shift these without the clutch, you put serious wear on the synchronizers. Do it enough and you'll ruin them and maybe other things, including gear teeth, and you'll have all kinds of fun double clutching because you'll have to.

While reading the following posts, I remembered some of my earlier escapades as 
a lad with my Dad regarding double clutching... Back then it seems I had an 
adversity to automatic transmissions and converted whatever I owned at the time 
to stick-shift (usually a four speed). Not having a welder at home to complete 
the cross-shaft conversion for the clutch, my Dad taught me early on how to 
drive a clutchless standard shift to the shop where the parts could be welded. 
Start the car in first gear, and shift at the proper time to a higher gear. If a 
stop was necessary, shut it down and repeat until your destination was reached. 
Worked then and will work now for those who find themselves "clutchless"....    
Cheers,    Charlie

Many years ago, I broke my clutch cable (on a Sunday in Utah) and learned  
really quick to shift gears the way the big-rig truckers do.  That  
knowledge has come in handy a good many times--especially nowadays when I have 
a  

hard time braking, then disengaging the clutch.  Shifting up and down,  
particularly up, without using the clutch comes easy--I just have to get my  
shift 

mechanism adjusted when I have made too many hard shifts when I didn't  
wait long enough to shift after letting up on the gas.

And  don't forget double clutching! For those who  have  unsynchroed
transmissions. Either by design or parts worn out!  Anybody have  a dogbox 
in
a Corvair?  Frank  DuVal
