Hopefully i can help..
From what you describe the best place to start would be the clutch issue you mention - if the clutch pedal has fallen to close to the floor - its possible being a hydraulic clutch operating system the problem is either with the clutch master or the slave cylinder at the gearbox - both of which have to be checked for leaks or wetness around the seals that maybe causing the system to loose pressure and thus creating a problem getting the gears shifted - this is because being hydraulic the clutch is clearing properly/or fully when the clutch pedal is depressed..if you find changing gears easier with the engine off then - the best place to start checks would be the clutch cylinders as above..I do hope this helps
thank you for your help will check for leaks
Hi..there..may thanks for your reply..
Yep certainly check both cylinders for leaks..thr master will be part of the clutch pedal.or what the clutch pedal actuates..so you need to get right up into the pedal box to check for leaks..the fluid will be exactly the same as brake fluid - next the slave at the gearbox..these will differ depending on the model you have one external you see if you follow the hydraulic lines from the master cylinder down to the gearbox..or the concentric type but unfotunatly that inside the gearbox bellhousing..but any leaks from that would be seen appearing from the the join where the bellhousing meets the engine....i do hope this helps further..please dont forget however to rate the answer above most appreciated..should you need to ask anything further then just ask..
