I have recently bought a 2004 Jaguar XK8 from a Jaguar specialist for £15,000. Having driven it for two weeks I have noticed a severe "snatch" between first and second gear (which appears worse if I accelerate hard). It is also noticeable, but less severe, going from second to first. All other gear transitions are very smooth. The car has done 85,000 miles and so I cannot expect it to be perfect, however I am concerned that there may be something seriously wrong with the gearbox. The car came with a six-month warranty. Do you think the problem is terminal? Should I take it back to be looked at, or do I live with it because of the age and mileage of the car?
