I got a 1997 JDM Type R, the guy I bought the car from was driving me to the LTO to get the car put in my name, the whole time (expect out of 1st) he was shifting with no clutch! So I got currious and tried it a few time, low and behold as long as you do it above 2000rpm's let off the gas and shift it will shift no problems! NO grinding no weard noises nothing. I was wondering if my trany is a clutchless tranny. If anyone could give me an answer that would be cool.

 

no, this is called speed shifting i believe....VERY BAD on the tranny.

have to keep the revvs constant and it will slip right in.

 

That's not speed shifting. But I guess everyone has a different name for it.

Anyways, you could do that with ALL gears as long as you time it right. Pretty senseless to do so since your driving a manual car for that clutch and shifter.

You can do it, going up and down gears with no problems as long as the revs are perfectly matched.

Non-synchro boxes are like this... but they have much stronger internals and can handle a blown shift.

Its a good skill to know how to use, if you ever need it on track, but I would not recommend making a habit out of - there's no reward for it, and the cost of a mistake is rather high when you have a clutch to use.

 

I do it on my beaters alot, but you can never match it perfect everytime, and it beats the **** out of your synchros.

The synchros job is to match the speed of the mainshaft (connected to clutch&gt;flywheel&gt;engine) to the countershaft (connected to wheels). When you use the clutch they only have to change the momentum of the mainshaft + clutch disc. Without using the clutch, you force them to change the momentum of not only the mainshaft, but the whole motor. Rapid wear.

 

Sweet thats for the heads up, But I don't understand when people say you have to time it right (granted I know its not good on the trany) but I can do it any time any speed as long as its above 2000rpm. But needless to say I wont do it I know getting a new trany is major cash over here. Thanks again peepz!

 

Going from gear into neutral at the moment you lift off the throttle is fine, so long as you are not accelerating or deccelerating (engine brake). Its going from nuetral into the next gear that you have to "time it". You have to match the rpm to the engine speed of the next gear given the speed you are traveling. Basically just wait a second or so after you disengage and let go of the throttle to have the rpms come down. You should notice the gear engages easier when you time it right.

 

yeah it does, but I'm done with that, beside its always a faster shift if you use the clutch

 

That's what rental cars are for!
