Questions about downshifting

[mutatio]

for non crazy drivers the rule of thumb is essentially that if u can get the stick into gear in the first place without forcing it, you're in a good place. anytime u feel it grind when u r trying to move it into gear means you're forcing it. as noted u may need to boost your rpms for it to slide in. but no, a double downshift isn't an insane thing to do, assuming you're being responsive to the tranny's feedback. i typically downshift from 4th to second around corners that i'm approaching at a decent clip. 3rd will do, but 2nd gives u the pull coming out of the turn and there's usuallly never any forcing of the gears. your tranny will let u know when it doesn't like what u r doing! ;) :)

No im not taliking about u taking a turn that u will brake first then switch to 2nd, im talking about non braking, double downshifting to gian extra speed when going straight. ANd what do u mean by forcing the gears??? i have never felt that before, the only thing i felt is that i can never shift the stick in to 1st whenever im over 10MPH and when u try to shift form 5th to R. the shifter wont let the stick to shift in ,in those two cases, but never felt that i have to force the stick in to any gears, im not getting what you are trying to tell me sry

If you're not using heal-toe to rev-match when downshifting, the actual process of downshifting for both speeding up or slowing down are executed in same manner. Once the shifting is completed, then you can speed up or slow down, but that's after the downshifting has been executed.

If you're not understanding (or it seems too simplistic), then I'd stay with the basic for awhile and just try to be smooth and keep the clutch burn to a minimum (meaning, avoid having the clutch partially engaged and accelerating while on the move). If you can do that and shift as smoothly as an automatic transmission, then the fancy stuff will be a piece of cake.

Usually when a driver is referring to forcing the clutch, it means not giving the synchronizers enough time to equalize the engine speeds (which will put extra wear and tear on the syncs). To give the synchronizer time to do their job, it's better to shift slowly, but not slow enough to be jerky with the car (everything still should be smooth). In my case, when I'm on the boil, which is most of the time, I'm switching as fast as my hands can move. But it's a trade-off, and manual transmission are usually designed to be abused. But there so much they can take and if you're in-experience and forcing things (in general), you're going to quickly wear-out your transmission. Mis-shifting is the kind of stuff that'll cause all the nasty noises from the tranny and the only thing that can be done it that situation, is to go back down on the clutch as fast possible.

the following basically covers it. :)
