For those who drive polo GTI

Hoyhoy.
I'm fairly sure that you will find it is the dog-bone bushing ( more or less the gearbox support mount ). VW has used the same bushing stiffness over the whole Polo range, which is not supportive enough for the GTI.
Guy Harding at Harding performance has some stiffer one's in production now, after doing a lot of experimenting with different stiffnesses. So keep an eye on his site, there are a few of us waiting on these things.

I have always noticed that, particularly in higher revs, the gearbox seems to make more noise when changing from 1st to 2nd, as opposed to changing in other gears. I don't mean a grinding or some other horrible noise, or that it is not smooth, more like you can hear the gears engaging more noticeably.

Is this related to the bushing stiffness? Not even sure if it is a problem, or just a characteristic of the gearbox.

Hoyhoy.
Well it could be another problem that some Polo GTI's have had.

Hey guys i have another prob with mine. It makes a metal on metal grinding sound at high RPM or under load in 1st and second. I had the syncro meshing prob with 1st and second and went away now it does this umm they seem to be the weak link to me.

After a while you just get used to the grinding crunch of 1-2 change.

Changing gears smoothly is really about matching the revs. I find at 3000rpm in first it is very smooth, but it varies from person to person. Like I said, blip the throttle if you are changing slowly so the revs match up better.

Drive faster. Hold some more revs in first and blip the throttle during the 1-2 gearchange.

I dont think bliping the throttle works on an up shift the engines revs will drop not increase after the shift, works on down shift only.
My grinding is not change related.

I find if the aircon is running the revs fall much faster than without, so to keep the rate at which i change gears constant and try to keep the rate at which the engine revs fall constant too.
