Problems with Speedo in Montreal

I just got my 92 spider S4 Automatic :), everything works perfectly on the car it has 50k kilos and original rubber,original british green, it has been really pampered. The only two things that dont work :( are the speedo works intermittently, once I have it up to 120 KPM it reacts and then works unless I leave it a day or two...I had some other cars where you could lubricate the speedo cable???? What to do.....

The other issue is the AC :( , is it worth having it fixed, can I just recharge the refrigerant??????

when I first saw this i thought you had a problem with an Alfa Montreal speedo!

So an auto S4? Not so sure you have a speedo cable on that one (someone know for sure?)

AngloSpider, a member in the UK had problems with his auto S4 speedo. The auto speedo sender is different to the manual sender, and you cannot buy it anymore....never seen them s/h either to be honest!
What you have is an impulse generator sender screwed directly into the right hand side of the gearbox, that sends a pulse to the speedo. On an auto spider you have in any case to drop the auto transmission down somewhat (as if you were going to replace the rear gearbox mount) to replace it.
Might be worth getting under there and at least checking the wires are intact and not chafing somewhere.
On the manual spider which also has a speed pulse generator fed by a speedo cable from the gearbox, then wires from th sender go directly to the Speedometer itself, going through fuse #7 (7th fuse from the left in the pull down fuse box)
I would check that in case the auto sensor runs through the same fuse (don't see why it shouldn't)....pull the fuse and clean the contact or replace.
Photo from the manual shows the location.
This link shows what it looks like as well as what it looks like inside, when Anglo got through gently opening it:)

Guys where would i look for the speedo sender for an automatic series 4......Is this veglia borletti sender common to other alfas or fiats?
I know it is 2 years old now, but this guy in Montreal actually was trying to sell one....whether he managed to? worth asking..though he hasn't been around BB for at least a year now!
