There is a dog gear ring pressed onto second gear, I'd like to buy a new one to replace it, mine is worn.

S2 Spider 1982.

I don't want to swap with 4th gears dog gear, I want a new one.

Are these available anywhere? I have not found any, so please let me know if I missed them somewhere.


Many thanks!

Dog gears

They have never been available.
You need to change out the complete 1st one direction syncro as well with a 2nd through 5th type.

Typically 4th and 5th syncros are good as new.

Thanks Richard, that's what I thought I had read in the various rebuild threads. My car is not subject to originality restrictions so I may just fit a T5 instead.

Although, the gearbox is near grunch-less when driven very very carefully it is punishing to the uninitiated. I have a 15 yr old daughter that can't wait to drive the alfa next summer and this winter we will either rebuild the existing box together or fit a T5 together as a father/daughter project.

Have a great Christmas.

My daughter learned to drive stick in my Spider with a gearbox that needed to be rebuilt. I figured that she could not make it much worse and she learned to double clutch. I swapped the gearbox when she got her own car.

you can make a T5 tranny to fit in the stock alfa shift area.. I just pm'ed you, just make shure the T5 is from a 95-99 mustang.. the gm versions are garbage ratios.. the mustang ratios are all the same 1-4, only 5th gear can be similar or a wee bit higher ( lower? ) for more or less rpms on the freeway.. I turn 3000 rpm at 72 mph. at 3300 80 mph,my T5 5 th gear ratio is .73......go to 'british V8' for a good ratio chart. hope this helps

If you can find one of the suppliers that have new gears you can get a new one. The new gear comes with the dog teeth. Unfortunately the dog teeth have never been available separately.

If you can't find the correct gear you need. You can buy any new 2nd through 5th gear and press off the dog teeth and put them on you original gear.

Around thirty years ago the Porsche aftermarket suppliers found a supplier in europe for the dog teeth. The outside is the same but the inside is a different diameter. It didn't match up to the 105 or the transaxle boxes. The price of the porsche dog teeth back then was around 60.00. I always wondered why the Alfa suppliers couldn't do this. Who ever could do this would make a nice sum of money when you consider the world wide market not just the US.

They have never been available UNTIL NOW :)

We are finalizing the testing of our new production 105/115 dog teeth, made by a well known premium gearbox specialist exclusively for us here in the USA.

We have spent a lot of time and money to ensure these are built to the highest standard, and in some ways (machining techniques and metallurgy have come a long way in the last 50 years) they are better than OEM.

For many years, the de facto solution for worn out dog rings was to source a good used part. Well its getting to the point where good used is often not available and the time was right to reproduce these.

Wow Joe, that is super-cool. Exactly what I was thinking, it must be getting to where we have swapped in all the usefull dog gears that ever were available and soon there will be none left.

There has to be some contingency, that is why I was looking towards T5.

I'm sure the whole community will be very excited to see this once it is available.

Thanks Joe.

Joe,

Will you be making dog teeth for the transaxle gearboxes?

Do you have a price and date on when they will be available?

Thank you for doing this.

To everyone who has been waiting for these dog rings; thanks for your patience.

I am happy to report that testing has gone well and these are performing exactly as expected. We rebuilt the gearbox in my '72 GTV using these dog rings and it feels wonderful with extremely clean and crisp shifts. We also had several of the top transmission rebuilders in the country install these and they have all had great results with them as well.

These are our part number TP218 and are available immediately.
