Changed my mind..

I found it unnatural and still do (I'm now used to it). I now have to think twice when I drive my other car (a Golf) and actually I've downshifted by mistake a couple of times in the Golf because of this. This had never happened when I had the first car. I would like to change to pull for up in the future, I find it way more intuitive.

Guys,

A good while after I posted the quoted text, I have changed my mind.. and I think I have a point so I'm sharing it.

I still find unnatural to push for upshifts and pull for downshifts as I find it contrary to the movement the the car puts in your body. However, I now use the clutch for downshifts only. I have found clutchless upshifts to be smoother by a lot. I was convinced by this excellent article which has been posted in other threads here:
http://www.hewland.com/svga/help.htm

To upshift, now I first push the gearstick gently, and shift by just lifting the throttle. That is, the shift doesn't happen until you take the "load" out of the gearbox, and when you do that, the gearstick magically lets your hand engage the next gear without any of the clunks associated with BECs. (When uphill, I haven't yet achieved shifts as smooth as when flat unless I'm accelerating quickly, but I suspect I just need to practice how to lift the throttle almost totally instead of totally, ie leave a bit of throttle.. maybe? Still smoother than clutch aided upshifts anyway.)

What happens now is that the natural movement that the cars puts in my body is actually helping me put a bit extra pressure on the gear stick at the very moment I lift the throttle, aiding quick and smooth shift.

Therefore although I still think that the most natural way is the opposite, I will be leaving my car as it is now (I had in mind changing it), and I now think that, in our particular type of gearbox, this helps natural upshifts, so I would treat this as kind of a special case?

Chris, Lightning, OX, timvangemert, Coose and the others who favour pull for upshifts, what do you think??

Cheers,

Alex

PS: can I change my vote now??

I would say "stock up on gearbox spares"

Seriously though, even when I clutchless upchange, I dont find there's much force lunging you forward when you slightly lift, there certainly shouldnt be otherwise it shows you're slowing down which is kinda against the idea of doing it so maybe you're lifting a bit too much?

Hmm, interesting point Chris, I'll be experimenting with less lift, thanks!

In a normal car from neutral, you go 1st (up), 2nd (down), 3rd(up), 4th (down), 5th (up). To my reckoning thats 3 forward shifts to 2 back. Therefore I conclude that it is more natural to push up when upshifting (which is possibly why its called such)

Thats my theory and I'm sticking to it.

Ah but my tintop has a 6 speed box, and its called upshifting because you're numerically going UP the gears
