Manual transmission repair — general information (Audi A4 B5)

1. Gearbox repair is a difficult task for a car enthusiast. In addition to the need to disassemble and assemble a mechanism with many small parts, exceptional precision of measurements is required and, if necessary, the selection of different bushings, spacers, etc. Internal components of the gearbox are often difficult to purchase, many of them are unreasonably expensive. Therefore, if the malfunction or noise in the gearbox progresses, it is better to entrust the repair to a specialized workshop, or purchase a refurbished gearbox for replacement.
