TS.Gearbox has limited slip differential so that may or may not be something your box has.Also many find the gear ratios to provide better acceleration.I have an actual 75 TS and I would say that overall the box is more pleasant to use than the one in my 86-GTV6 .

If we are talking 75 boxes the actual ratios are the same but the final drive is 4.1 in the TS vs. 3.55 in the 3.0, both have LSD.
Clutch is different too.

Mats,
I just took my 75TS out of winter storage and took it for a ride.Man I love this gearbox.I think I'm going to have to plug one into my GTV6.Is it just the final drive that produces this different feeling ? It feels so much more "modern" than my GTV6 and somehow the throws don't seem to be as long-but I guess that's just my imagination - well better go out for another drive.

Well compared to the GTV box there are some things that are changed, the first three gears are taller on the 75 box, there is an LSD and the gear linkage is different.

Mats,
When you say that the gear linkage is different are you referring to the external components ie:isostatic linkage.If so I'll have to crawl under there and have a look because the shifting sure feels more precise than on my 86 GTV6 and I have replaced all the isostatic parts on that one.I would rate the GTV6 shifting as acceptable but certainly not great.

When you can shift a 116 series like a 105 series you know you have reached the holy grail-you're cookin' with gas man!!
Until then it's just a wooden spoon in a jelly bucket.

Hmm, im going to be getting a 75 TS box in the next few weeks, i've got an '84 GTV, the only thing i've heard that is different is the speedo setup. can anyone elaborate on this for me?

How good is the Gear Box in a 2.5L Alfa 90?
Does anybody have the comparison between the mentioned TS Gear box and the 90?

You're right. I should pull my head in. You know, do a vanishing act like the turtle.
Asking me to do a kit is easy enough. What I find on this forum is that it is a site that has mostly guys who want to have a go at doing things for themselves. (and fair enough too) However sometimes they want to know every little detail and occasionaly the detail comes down to sensitive commercial information if somebody has spent a lot of time and effort to develop something. This can result in a sort of commercial conflict which puts everybody on edge. Being an active contributor to the site as well as having a commercial interest is very thin gangplank indeed.
(Maybe there is room for change here Michael and perhaps we could have a poll or some general free discussion as to the merrits or otherwise of having a mix of commercial interest as well as just enthusiasts. Personally I am in favour of it. We are currently co-existing with some of these contributors in a more or less defacto way without any problems and to the contrary, they are some of the best contributors the site has. Over to you, Michael)
So on the one hand I agree with you but on the other, I dont want to be in the centre of any poo fights over something which was supposed to help someone in the first place.
Incidentaly, before this post accidentally refires any sort of resurfacing of stuff that has gone down before, I plead that it doesn't.
I am more than happy to assist anyone who has an interest in my shifter design to build one for themselves for free.Yes it is a thorough pain in the butt to make however when it is done, you will wonder why the f**k it took you so long to decide to do it.
...and no, I won't mention it again unless asked to do so.
BTW The next time you are in Brisbane, look me up and and you can have a drive of my car just to prove it to yourself how much better my set up is.

Thankyou for the kind offer MD !I would love to take you up on that offer next time I'm in Sunny Queensland.
I hope my asking MD to produce a kit does not cause any conflict on this site as that is not my intention. But on the other hand I welcome all improvements to the GTV6 and to this forum .I applaud members of this site who spend there time and money on research and developement then to offer their improvements / ideas free of charge (I personally would be more than happy to pay as some of us don't have the time or expertise to carry out some of these improvements)
