Nissan Repair: Nissan Terrano II gearbox, nissan terrano ii, clutch master cylinder

Question
Hi. Am finding it very difficult to shift in gear (all of them). I did a test and I can change gear when the car is switched off but am having problems when the car is on to the point that I cannot drive it any more. Any ideas please? Thanks for your help.

Answer
Gaby,

The clutch master cylinder or slave cylinder is leaking and not allowing you to get the clutch released all the way.  Replace the slave first and bleed the system.  I would replace both since they fail close together.  Bleed the system and you should be fine.
