I've got an auto diesel Colt, March 05 reg, now out of warranty but with a further 3 years extended cover. There are now some 125,000 on the clock. A few weeks ago the gearbox appeared to seize. The garage diagnosed worn clutch plates so this was not covered by the warranty. They replaced the clutch plate and I had to pay the £1,000 bill. A friend tells me he's never heard of clutch plates going in an autobox.
