I was able to go from first to second and from second to third without using clutch. You got to be cruising at certain speed and just glide the stick from first to second while releasing accelerator and once it slides into gear start accelerating. Worked great on Civic and I did that for 2 years without any damage :-) I guess it depends on a design of transmission and probably easier to do it on front drive cars.

 

I've done it a few times on my GT and it is actually not as difficult as i expected with the car. i dont' recommend doing it but it is in fact possible. like previous posts say, any truck driver can relate. pull out of gear around 3000 rpm, apply pressure the on the next gear your going into and allow the rps to drop... eventually it'll pop right in there. a little harder when down shifting, you actually have to rev the car up the the rpm that the gear would normally produce at that speed and it will go.

 

it is very easy to do...I used to do it all the time in an old '83 Jeep CJ7....infact, one time I lost a part of the clutch linkage, so to drive it home, I had to put it in first, crank the engine, and give it gas all at the same time......it jerked a bit, but did go...then I just drove home without a clutch...

by the way, I think it is refered to as quick shifing.......way back when I had my jeep, my neighbor who is very knowlageable about cars told me once it was built into cars built after....sometime in the early 80's, obvoiusly before 83.

Don't know if that is true or not, but I know you can do it in the Mustang....you just have to be patient at it....it works, but there really is no point in doing it, except to say you did it.

 

Clutchless shifting is very possible with constant mesh transmissions, ie. commercial trucks, and even motorcycles. But this is a tough one with snychromesh transmissions. You're asking for tranny damage, particularly the snychros, and it's generally not faster with a synchro tranny.

 

I like my tranny as-is, teeth on the gears, etc. I'll pass.

 

truckers do it not to save wear, but because they dont have sychros, the must double clutch and that takes a lot of time...


its very mechanically psibble you just need to match the road speed to the RPM for the gear your choosing.. i do it all the time,

the way our trannies are built is irrelevant as to if its possible or not

 

that's what you have syncros for...

 

My sister used to drive a dump truck years agoand she wouldshift without the clutchall the time. She called it power shifting and said that it helped her left leg from getting sore.

 

This post is like 2 years old....Oh it a newbie.....LOL..Well it's a way for me to get a history lesson here. Nascar drivers do it too

 

Yes, it is a difference in the designs of the tranmissions. The trans in our Mustangs were not designed to be shifted without the clutch. It will cause premature wear and lead to failure. Large truck trannys have a strait cut gear tooth which allows it to be shifted by the RPM's. NASCAR drivers only shift like that on road courses, with a tranny specificaly designed for road course tracks. I drove a truck for 8 1/2 years and the only time I used the clutch was to start and stop.
