Have had clutch and cable replaced about 30,000 miles ago. Just recently the clutch has been juddering a bit when released if revs were a bit low; today the gear change has been very lumpy and when I tried to park this eve it didnt want to go in reverse there was a great deal of crashing before it would engage. Is this problem likely to be easily resolved or does it mean another expensive clutch? :rolleyes: Its only done 137,000 the engines fine cant afford to replace it yet. Would appreciate any assitance.
