We are experts in this field - for example, here's a "word to the wise" about gearboxes from Andy French, Workshop Manager: "Transmissions are now extremely reliable components and with regular maintenance will give thousands of miles of trouble free service.

If the driver does report something wrong with the gears, do investigate or you risk consequential damage to other parts of the transmission which might be far more costly to rectify".
