anyone know if the outer ring gear from a spider tranny gear will fit a GTV6/milano tranny.

I know that the three armed piece does not fit because the inner shaft hole diameter is different. BUT, the synchro friction rings and sliding gear are the same and do fit.

it would make sense that the press on ring gear would fit universally just like the slider. I want to repair a Milano gearbox. Replacing just the slider and not the press on gear does not make sense if they are both worn.



1) SO, if anyone knows if the 'press on' synchro ring gear mated the the actual gear from spider tranny fits GTV6/milano, please let me know. I don't have one to measure.

2) Also, if the four little metal pieces also fit (called ring locks or something: two are curved and two are small blocks))

gee...nobody knows??

seriously...nobody knows??

Honestly, who gives a shit about the spiders?

Rumour has it that the later style GBs have the same press on dogs.

Also, the three arm things do have different diameters (on the different pieces) on the 75 as well if memory serves me correctly.

Mats: Thanks for the reply , but Try actually reading my read my post

I don't care about spiders, but there tons of cheap spider trannies in the junk yards. I know the main 1-5 gear shaft diameters are different, but that does not imply that the press on synchro gear is is also a smaller diameter. To save money, it would make sense for Alfa to use the same synchro 'press on gear' and 'slide gear' for many models since these are wear down parts. The 'three armed piece' is of course different.

I am not sure what an Alfa GB is....

GB = Gear Box...

What I meant was, since I don't really care for spiders I have never worked on them and therefore don't know so much about them. I guess that's why there are no responses.

The three armed pieces have different sizes in the Alfetta/75 boxes too. you can't move the 1-2 "hub" to the 3-4 position and vice versa. Maybe there are some from the Spider that are shared with the Alfetta/75 box but in a different position?

Got it, thanks Mats..

If I come across a Spider tranny for cheap, i will pick it up and answer this question...

As a note: Three armed piece has a different center shaft diameter (spider v. GTV, Milano), but does have the same outer diameter since the arms fit the sliding synchro gear. The sliding synchro gears are the same in the spider and the GTV/Milano.



The post below is from our own site regarding GTV/milano transaxle fixed synchro gear mounted on the main gears (which are harder to find):

"What actually happens when you change into second too quickly with those worn syncro's? What makes that grinding noise? Well, it's not the gears grinding, its the small teeth on the component shown in the (lower) centre of the above photo. The grinding occurs when the syncro's have been unable to synchronize the speed of the gear and the syncro sleeve as it moves over to engage. These tiny teeth eventually get worn out. How to replace these teeth is a problem (short of purchasing new gears) - unless you have access to some junked gears from another gearbox. It is possible to pull the needed component off a gear using a simple 3 leg puller shown at the top of the picture. Obviously, it is better to use the donor engagement gear rings from 4th and 5th gears since these will be the least worn. You can then press these onto your 2nd and 3rd gears - there you have it 'as-new' gears!"

Anyone that can use a puller like that to get the dogs off of a first gear is worth an award of some kind.

I was not quite sure how he did it either......

I use a stainless knife and a hammer...

so they separated fairly easily ?

Never said it was easy...

all right smart ass, HOW DIFFICULT was it?.......

Did you you a butter knife or a paring knife??? or a cleaver?>????
