Appear to have developed a perplexing clutch/ gearbox problem. Problem has been getting progressively worse over the past 6 months. Ferrari is a 1994 348 spider with 48k miles. Symptoms are difficult to engage 1st, sometimes any gear from neutral. Difficulty seems slightly worse when warm. Generally engages with no problem cold. Neutral at a stoplight, will not shift into 1st. Often will shift into 1st with no effort if reverse or 2nd engaged before 1st. Recently all gears difficult to engage when stopped. After start, all gears change etc with no difficulty. When difficult to engage, there is a slight sound, lever will not enter gate. No grind or chatter felt through the lever. May be slight car motion as found in a dragging clutch, not sure. Clutch engages over halfway from floor. Action feels normal. No improvement if I pump the pedal. No leaks at the clutch area that I can detect. Recently bled with a MityVac, not sure if correctly done. Adjusted linkage, lever centered in the gate. Comments welcome, thanks for the help.
