The Milano 2.5 platinum comes w/ LSD.

 

Agreed. Platinum has LSD. Also I believe the Gold/Silver have all the same gear ratios as the Platinum, without LSD (as you have noted)

 

Ok, I'll take note, and will upload the updates.
Also, what about order the cars by capacity?

The EURO 75 2.5 V6, does not have LSD fitted....

Alvaro, good job. The closest ratio first gear should be 2.875.

The new Giulietta also came with 1.8 and 2.0 engines (at least in the UK, my first Alfa and first new car, was a 1.6 Giulietta). That also seemed to have an overdrive 5th from memory.

Is the closest ratio actually buildable?

 

Hi!
I've uploaded a updated data sheet.
You can see it in the opening post (800x600) or bigger (1110x755) by clicking here:

There are still some gaps to fill and a couple od gear ratios to be confirmed:
- Early USA GTV6
- Early Alfettas
- Alfetta Coupe 1.8
- Nuova Giulietta... all models.

Best regards,
Alvaro.

 

nice work, should be handy fow a few people.

 

Updated list!!!

Hi!
I've updated the list with some new sources and some info provided and confirmed by AlfaBB Members and other owners (many thanks to them!!)

Edited 02-26-2010
Corrected and updated, see latest post

Hope you'll find the info useful.
Regards, Alvaro.

 

Wow, excellent!! I've been looking for this info.

I am driving an 83 GTV6, which had really tall gears. I loved it on the track, and 2nd was so much more useful around town. It suffered a major malfunction, and I mistakenly figured the early gears were all the same, as opposed to later. I put in an 81, and it has the same gearing as an 86!! Nice synchros though. I want the taller gears. Hopefully I can decipher this table and pick the year I need. I'm pretty sure I have every year in the yard. Any advice?
Thanks,
Glennck

please excuse my seeming ignorance, but it looks like the FINAL gear in the 82 is what makes the gears so tall?

 

Hi!
Yes, seems some '82 units here in Europe and the most of the units exported to USA, were fitted with a very tall final gear ratio.

This info must be still confirmed by factory papers or by owners with cars strictly original.

Regards, Alvaro.

 

Early Giuliettas

Final drive:
1357cc = 43:9
1570cc = 43:10
1779cc = 41:10
1962cc = 41:10

Gearbox on all the above:
1st = 3.307:1
2nd = 1.956:1
3rd = 1.345:1
4th = 1.026:1
5th = 0.833:1
Reverse = 2.620:1

On the "facelift"
Final drive:
1570cc = 42:11
1779cc = 42:11
1962cc = 43:10

I've also heard that the Giulietta 2.0 TI have a even shorter final drive. I dont know for sure, but what i DO know is that my own Giulietta 2.0 TI has about 4000 rpm at 110 km/h. And that is pretty high.

All the above engines are NA. The info comes from my original handbooks.

 

Hi!
I'll add the info to the datasheet.

Thanks a lot.
Regards, Alvaro.

 

Errors

Hi!
I'll add the info to the datasheet.

Thanks a lot.
Regards, Alvaro.

There are numerous errors & ommissions in your listings. See other post on transaxle ratios.

Hi!

What post?
If you can detail the errors, I'll correct them ASAP.

Regards, Alvaro.

 

Thanks for the work.

We bought an 85 GTV-6 with a couple of spare (broken?) transaxles. Are there identifying marks that would let us know which they are. We have dreams of one of them being an LSD, and we'd like to know.

Thanks,

J

 

Hi!
Yes, the crown should have the ratio stamped.

Regards, Alvaro.

 

Hi!

Datasheet corrected.
Added the Early Giulietta ratios, and a couple of details.

Regards, Alvaro.

 

Hello Alvaro,

I'm helping out a friend (that writes at the Portal dos Clássicos Portuguese forum as yourself) swaping his Giulietta gearbox for a 75TS one.

The Giulietta is a 2 liter 2ºversion with plastic bumpers and external fog lights.

For what I've read in your list it has a 4.3 final ratio. The TS gearbox has 4.1 Final ratio. Is this correct?

I don't understand some of the values you have there: Why in the Alfa 90 and Giulietta the smaller engines have longer ratios than the big engined versions?

Best regards

 

Listing incorrect

I thought you were "researching" your project? Not to a "C" level yet!

Read UP!
Early Alfettas ratios: 3.3/2.0(not the 1.96)/1.34/1.04 (not the 1.03)/ .83 (these are the heavier "coarse" cut gearsets)
All Alfettas had .83 fifth gears.

There are 3.0/1.96/1.25(not 1.23)/1.03/.83 gearsets in Which model? Study!

 

can someone confirm that the 75/milano automatics have an lsd? and is the lsd centre interchangable bettween v6 transaxles?

 

Brad - in Australia believe the answer is yes. At least that's my memory of a 75 Auto we had and the wild slides it was capable of!

The 'other' thread probably refers to the 'other' GTV6 forum.

Good ratio discussion at AlfaGTV6.org

PS how is Richard doing? Richard?

 

Early US GTV6 is identical to Euro 1981 GTV6, both gear ratios and ring & pinion.

 

This may be of some interest too...

engine rpm at 100kmh

A similar discussion with useful info...

 

Idealy wouldn't you want the 3.50 tranny over the 2.78 tranny, it you liked faster acceleration along with the 4.10 gears? Of course you would have to get a milano lsd for better traction. I see they all have the same final gear, so it depends on how much you like accelerating. So early GTV6 tranny with Milano lsd right? If you were tracking your car you would want the same setup so you can pull hard out of the corner as well, right?

 

Transaxle Ratios

No, you don't want the 3.50 ratio transaxle as the gear spacing is really far apart. You'll have a lot of RPM drop with each shift. Also you only use first gear for getting the car rolling from a stop.
I'm in the process of building a box that uses 1st and 2nd from a Milano and 3rd-5th from an Alfetta. The hard part is the 5th-reverse cluster but we have a couple of different ideas on how to over come that problem.

 

Don't even know if you need these 78/79 A/T Sedan

2nd 1.48

The section showing the Australian and Swedish 75s is wrong for Australia. Our 3litre cars had either the standard 3.55 LSD or the 3.73 LSD in the QV, or Potenziata, as they are called here. The only four cylinder cars we had were the 2.0 litre Twin Sparks with the 4.10 LSD box.
