Hi everyone, I have a Y61 TB42 manual (rare, I know, but trust me, this is the config from factory). As the vehicle gets warm the clutch starts to slip, or doesn't release smoothly. I am not an experienced automotive mechanic, but am capable with a tool set. I am also in a fairly remote location and need to fix this myself.

Main question is, how to I diagnose the problem so I can order the right parts the first time?

Any all advice appreciated.
