Disassembly
Self-repair of the gearbox is not recommended, as certain qualifications and special tools are required (various pullers, micrometer heads and accessories, pliers for removing retaining rings, etc.). In addition, spare parts for gearboxes are expensive and difficult to obtain. Therefore, it is recommended to hand over the gearbox for repair to a car service, or purchase a restored unit.
