td4 high revs but no power

my td4 2001 seems to rev ok up to 2500 but then revs fast with no power, which can be nightmare when planning to over take. The car will pull away fine and no problems with gear changes. it just seems to lose power and rev after 2500 revs as if the clutch has been engaged!!! any help would be great.

Seems like your describing clutch slip (revs increasing without car speeding up) in which case the clutch will need replacing.

thanks chaser, i think this is one thats out of my depth then. i noticed your in cheshire do you know of any decent garages in the north west that won't "take me for a ride" pardon the pun!
