Says the guy who's never replaced a clutch?!?
Like scootr, I seemed to go through them faster when I was young. Conversely, I think my wife's last manual car had close to 150k miles on the original clutch when we sold it, still holding strong.
I remember when the clutch went out on my last Chevy 1500, I had a broken shoulder, and so was unable to do the job myself. I took it to a local garage who had a very good reputation, but a year later it failed again. This time I pulled it apart myself and found a damaged pilot bearing in the rear of the crank shaft. You guys know the one.
I pulled it out and took it with me to the parts store, where the parts guy told me it was the factory original, easily identified because GM changed the bearing style just a year or two after my truck was built. Long story short, the mechanic I had paid for my clutch job tried to remove the original bearing, and his puller must have failed him. So he just left the original in there, but now damaged from his puller deforming it a bit. Of course it failed again within a year.
So yes, manuals are
usually more trouble-free, but not always!
