I have been a Classic Mini enthusiast for over 20 years, and in that time I have probably encountered most of the problems which will interrupt the enjoyment of your vehicle. One which is becoming more common as the age of the Mini increases is the demise of the gearbox. Its design of sharing the oil with the engine is unique, but does mean that there's a compromise between the best oil for the engine verses the best oil for the gearbox. The end result is wear on the gearbox components.

Although inevitable, the solution is simple. A gearbox can be reconditioned.
