Alfa Romeo Repair: shifting, hydraulic clutch, clutch release

Question
I cannot get my 79 spyder veloce to shift into 1st or 2nd gear. 3rd and 4th are fine. i cannot find a repair manual on it, and don't want to start digging in without a good idea. Can you help? thanks, tom

Answer
Do you mean that at a dead stop (not rolling) you can get it
into 3rd gear. If so, the clutch is releasing only partially.
There is air in the the hydraulic clutch release system. Flush
with Castrol LMA brake fluid. If that does not cure the problem you need new master and slave cylinders.
