shifting without the clutch...

M1K3 · 02-20-2010, 11:16 PM

So I've heard it can be done. But can it be done on newer cars, namely the z?

yea, you have to steady the rpms at the right speed and the gears slide together.

I wouldn't bother trying it, just to save the life of the tranny by not grinding gears trying to learn.

The idea is to apply throttle so that as you slide the shifter out of gear, the rpms stay where they are, and then lower the rpms to the appropriate speed to engage the next gear. seems simple, but its only useful if your clutch ever takes a crap.

Hmm..that's cool..now since our car rev match on downshift would it not be easy to shift down w/o the clutch as long as you have the right rpm to get it out of gear?

OP, can you not shift?
lol...
Why'd you get manual then?
Do it the right way!

I did it when the trans in a former car took a dump just to limp it home. I'm sure someone can learn to do it quite well, but I sure had issues with it.

Also popular amongst semi-trailer truck drivers ("18 wheelers") because of the larger amount of gears they have to get through... but they also spend a good bit more time driving than we do.

It gets annoying for them to keep using the clutch.... much easier to ruin the trans...LoL

SRM cant be used if you try this method because you have no throttle control. you would need to turn it off. the idea is to raise or lower the rpms BEFORE the gear is engaged, SRM revs after.

What a helpful comment

Anyway other posts sum it up. I can't do it that well on my friends car but he can do it just fine whenever he does. I guess it just takes practice...

Thanks for the info. Btw yes I can drive manual....was just curious and always like to learn new things that just may be used sometime. Thanks again!

Truck tranny and car tranny are different though.. one has synchro mesh the other doesn't. Trucks really don't need it for the gears other than say 1st and Rev.

This thread seems to pop up on all kinds of forums. I was reading an E90 BMW thread where they discussed the very same topic. The posters above are correct in that it is possible if the RPMs are matched, but if not....

. I wouldn't dare try to do it, but if you are not worried about messing up the tranny then go ahead and try it.
