Well, well! This thread has risen from the dead! :)

When I saw this thread just now, I thought to myself: "Ooh, my gearbox used to do that", then discovered that it's my thread! :clap:

Now that mine's got 60,000 miles on the clock, it's much smoother. And I never did change the oil or do anything to it - I think it has just matured well! :)
