Hi Eric, just saw this thread, dig the brown coupe. No harm with the automatic.
I am also an Alfa/Italian car person, although I started out with the BMW. Have a 57 Sprint and a Jr Z at present, and I concur that Italians invented rust and Karmann just stole their idea.
The BMWs are refreshing because things like their 50 year old original instruments and electrical systems tend to work. And the engine is so sweet. But they are luxury cars compared with little Italian cars.
Your transmission is a Borg Warner unit, and if it ever needs a refill it can be done at AAMCO or any similar transmission specialist.
Enjoy the project!
