Not my car, be better if someone with more knowledge specific, could chime in
If it was a DIY repair, we would have to start to narrow it down, via diagnostics, engine/gearbox mount, hybrid system, engine running issue,gearbox, clutch, drive shafts and so on
A few observations
Or whatever it is, might not be clutch or just clutch
Stalling easy, plus judder, worse when cold, sound more engine
Car jolting forwards, does not sound like clutch to me
Not sure I understand what you are trying to say
Solid flywheel
Doesn't fit with the other symptoms, stalling and lurching forward
Agreed
Oil from the gearbox does not contaminate the clutch, it all flung off and runs out the bottom
A failed input bearing does cause judder as the shaft wobbles around, but will not cause the car to lurch forwards
Like when you first start to drive sound more like kangarooing than judder, along with jumping forwards
Agreed
Fingers also crossed
