Hi everyone! Was looking for some input to see if anyone has any experience in this.

2008 Aston Martin Vantage V8 4.3L
Sportshift transmission

Rough scraping noise when changing gear.

Up shift
1st to 2nd gear - smooth
2nd to 3rd gear - “Kak!” Noise
3rd to 4th gear - “Kak!” Noise
5th to 6th gear - smooth

Down shift
6th to 5th gear - smooth with down revving
5th to 4th gear - “Kak!” With no down revving
4th to 3rd gear - “Kak!” With no down revving
3rd to 2nd gear - smooth with down reviving

if I change gear in Low rpm, it will be a soft “Kak” noise.

If I change in high rpm (>3k rpm), it will be pretty loud.

During morning cold start, there will be no scrapping noise till about 5km in.

I want to fix it badly but not sure what is wrong with it. Anyone encounter similar issue before?
