Tinny Rattling sound under the gearlever

The car came with this really annoying rattling under the gearlever that could be stopped if you pressed the lever to one side or the other.

People on the MGRover forum suggested that it might be a rattling heatshield but once the car was up on stands and the front plastic under-tray removed, it was easy to determine the cause.

The PG1 Gearbox has two linkages selecting the gears. The rattling was caused by the one that pushes the gearbox selector in and out. It's a sort of universal joint that sits higher in the car than the other linkage and there was too much play in the first part of it which meant that the selector shaft (between the gear lever and the joint) could rattle up and down.

I cut and opened up a stainless washer and then tapped it into the gap between the selector shaft and the metal pressing that retains it. This appears to have cured it for now but if it happens again I'll take a look in the parts manual because it may be that there's a rubber bush here that needs to be replaced.
