Agree. The gearbox itself should be very long-lived: if everything works right there are no missed shifts, no improper clutch action, no gear clashing, etc. The microslipping (if that's what we're experiencing) seems to occur when not a lot of torque is being transmitted, so I'm not that pessimistic about clutch life either.
