Since there is no throttle application it doesn't do much other than just jolt the whole car. It's a bit shocking as the downshifts are at that speed are very gentle with lots of clutch slip, but when it slams there's no warning just a jolt.

It's really infrequent, only 3 times in its life and I've owned the car from new, the last time was today and it's maybe one time per year, so obviously very, very infrequent. Anyone else have this happen? I doubt that the dealer will be able to detect anything but since I'm close to out of warranty I wonder if it's worth telling the dealer.
The dealer can calibrate the clutch for you and 90% of the time it will solve your issue ..

Good
Luck
