My 308 is now on the East Coast! The hauler arrived today and had to drop off at a local Walmart parking lot because the 87' truck could not get through the windy roads. On the short drive from the drop-off point back to his shop, David was able to do a quick evaluation:
"We’ve got our work cut out for us ahead. I suspect that she’s running maybe on 5 cylinders and has a significant vacuum leak somewhere, based on the way she smells...
I’ll get the diagnostics done this week and report back when I now more.
The transaxle is well, as you described."
Ok, good -- so it's not just that I don't know how to shift this Italian transmission. There actually IS something wrong.
