Identifying Allfetta transaxle vs GTV6 transaxle

I think the original owner may have swapped the transaxle.

My 1978 Alfetta has 4 studs per wheel.

Is there any identifiable way, without disassembly, to tell if the transaxle is the Alfetta original, or been swapped from a GTV6?

From what I remember Alfetta had the clutch slave cylinder mounted to the clutch assembly/housing. Gtv6s had it attached to an alloy plate that bolted to the intermediate flange between the front and rear transaxle cases.

Here's a photo of a transaxle from a Milano (same as the gtv6). The slave cylinder is in the middle on the passenger side.

I just had a reply from Giovanni Di Fatta, Di Fatta Brothers | Alfa Romeo Parts | Fiat Parts he says the following:
Quote:
One quick way to tell, Alfetta has cable for the speedmeter, the gTV6/milano are electronic
Quote:
The Alfetta Axles are smaller, they use the same rear brake rotors and calipers, the rest is different.
I won't be at my car until this weekend, I'll be looking closely.

Great information everyone, thanks.

Question about the clutch slave,
Alffetta clutch fork looks like it 'pushes', how does the GTV6 slave work, does it 'PULL'?

Transaxles

The 4 cyl Alfetta uses a push system while all the V6 use pull type.

Either clutch will fit with only a change of the release "ball" and release bearing centering sleeve.

Early v6 transaxles had gear drive speedometer design so the 4 cyl cable adaptor would fit. However stronger, the V6 transaxles all had crappy gear ratios for economy and fuel milage standards.











Either will fit
