Radical Gear Selector

For those of you who are interested in an alternative to my selector could consider this commercial proposition from Xtrac in the UK. The following photos are of an installation in a front wheel drive vehicle so you have to imagine the linkages going the opposite way. What is at issue here is the exellent changing mechanism that can be set up just to suit you personal requirements.

Nice site, but it would be helpful if you could guide us how to find the gear selector thingie. ;)

Yeah don't blame you Mats.

I will try and contact them to see we can narrow down the info and point of supply. For now the main site is all I got.

Is this it?

Looks cool, but I don't really see how it would work in a GTV6/Milano...

this item is for sequantial gearboxes.

its important to know what is the health of the gearbox before do change the stick.

Sorry Mate, that's not the one.

Looks big enough even Arnold Schwartzenegger !!

I got a collection of pics on my files and I am working on reducing the files sizes so I can post them soon I hope.

....once more with a feeling

As to where you get one of these guys, well the best I could do was to provide a start with the link above but it is bit of monster to sort through and I must admit I myself have not found the actual details there yet (I am working on it). But it is a start for all you ferrets out here.

These pics are from a local front wheel drive race car. You have to imagine it working in reverse order but the application principles are the same.

hmmm looks very good but our alfas are transaxle ... with this shifter you will turn gearshifting opposite ... first will bi left and back and so on .... fixing point of this shiftier is on bottom ..on transaxle alfa we need fixing point on middle of the shifter ...
OMG sorry but i hope you will understand my bad english :lol:

That's actually very easy to work around.
But I still don't see how it is better then the original (old) linkage where we have one (1) joint in total in the whole linkage.
It doesn't get much tighter then that.

Glad to see somebody is actually thinking about this item because it is a great racing shift solution. Yes, you are correct that you will have a mirror opposite shift pattern but as Mats says, that is easily rectified. I actually had this pattern in my car for about six months as an anti theft device !

Mats

You just have to believe me that the original design is sound but the problem with it is the length of the lever points. This is what causes the long throws and wide gate. Otherwise you too are absolutely correct. The fewer the moving parts , the greater the reliabilty- and engineering fact. However, when you get this sucker right, you are talking about a difference of 99.5% vs 99.8% fantastic (as a concept) so it is very worth while pursuing.

Put simply, the set up that I use and illustrated on the old site has as sharp a feel as a 105 stick- in- the- box but with a shorter throw like an Ford Escort for example. Gone is the slop, the long throws and wide gate and the general vagueness of where the gear actually is.

There are no royalties in this for me so I am not pursuing it for any other reason than to genuinely give Alfa racers an opportunity to think through an alternative because you don't have to put up with what is there. There are better ways and this type changer can get people thinking to find that alterantive.

If you can't stand the standard shifter I'd say this is probably the best solution yet.

However, I test-drove my newly rebuilt gearbox yesterday and it was just bliss. :D
Super tight, the gate was just incredibly crisp and all the gears went in quick and smooth, and I thought my old box was alright... :)

I have to say that a good shifting transaxle is a very nice thing indeed- when they are all tight, and you know how to drive one, it doesnt really matter too much anymore-

Even when I fit my 4.3 diff up, and had the syncrhos swapped, the thing became so much better to punt around.

Im more along the line of thinking that I just cant stand a transaxle at all, anymore! I think I will be cutting the tunnel out and fitting a bigger diff in my car's next incarnation...

a bigger diff..?

To be honest, I really want more power. But I cant be bothered spending all the money needed to make my 2.5 a faster engine. I love it to death, but I want to go harder!!!! I want to embarrass GTRs and Turbo Rotaries at the strip and the track. I want to prove a point!

Twin Turbo 24v is looking more the best way to go. Im not gonna stuff around with naturally aspirated engines after this 2.5.

Well short of fitting a Porsche G50 transaxle, one thing I like the idea of is to fit up a locally manufactured Holden (GMH) Commodore Gearbox + IRS rear end- they are made for an injected 350 Chev, so they aren't short of strength, and available in many many ratios, and and are easy to get hold of over here.

Either way, it means stripping the interior, and having a cage to tie up the shock towers, and likely, strengthening of the anchorage points for the diff and IRS arms.

If it all looks like too much, then maybe the POrsche G50 is the way to go? For 5k -10k rebuilt, if they are good enough for an Ultima GTR, good enough for a GTV.

Flight school is helping me hatch all sorts of inventive plans for my car!

this is the best solution(for me) to improve transaxle shifting (ultima's shifter mechanizm looks damn good) :)
