I am looking at getting a circa 2004 L322 TD6. I note that many of the higher mileage cars, 120k plus, have had a replacement gearbox at some point. This to me seems like a good thing as someone else has had the expense and hassle of doing what sounds like an inevitable job. Having said that, I am trying to get one with nearer 100k on the clock, and many of these don't mention a gearbox replacement. Am I being silly going for a lower mileage one that hasn't had the box changed/reconditioned. Is it just a job that I will almost certainly have to do at some point? Is it better to buy a higher mileage car with a bill for a recent box? The big question of course is, how much does it cost to replace/recondition a gearbox in one of these? There must be plenty of experience on here judging by how many I have seen that have had this work done.
