What oil are people using in their transaxles?
The original Fiat spec was for SAE 90 EP oil, which is an obsolete specification.
Paul of Scuderia Topolino recommends Red Line MTL, but it is only a 70-80 wt oil.
They also make a MT90 oil, which is a 75W-90 wt, but it probably will not give as easy shifting.
What do people on this forum use?
