I had my clutch replaced about 2 yrs. Ago as it was slipping. Well, it is slipping again and I’m thinking that the repair should have lasted longer than 2yrs. and I want to confront the mechanic who did the job. Am I right, or could I be doing something to cause this? I’ve only had the car 5 yrs.The car is a 5 speed and I have driven a standard for 30 yrs.!
