This is a used gearbox that has been opened up, and all the wearing parts replaced with new, original parts. Whether bearings, sprockets, synchros, seals, etc., each gearbox is literally dissected by our technicians and meticulously reassembled to give it a second life.
Of course, once the work is completed, each box undergoes a battery of tests to guarantee its perfect functioning. Whether it's an air pressure test to prevent leaks, or a bench test on which the gearboxes are put through their paces, when the finished product leaves our workshops, it comes with a 12-month warranty, just like a new gearbox!
Every year, more and more motorists opt for reconditioning, especially when it comes to large mechanical parts (engine or gearbox), because new is often unaffordable, and second-hand for these key parts is more like a game of poker than a long-term investment. Indeed, the mileage of a used gearbox is often uncertain, and as happened to yours when you changed it, the probability that it too will break down remains high, since it has already lived. This would be the worst-case scenario, as you'd have to look again for another gearbox, buy one and pay for a new one at the garage, with all the associated costs such as oil, etc.
