Thanks!
I belive I did just like the description (actually read that post before I got at it) but I may have been to quick calling it success.
Will try to fill it up further when i get back later tonight and cross my fingers that its all it takes, hopefully the few miles it went after the noise appeared didn`t shatter the box. The strange thing is that it went as far as close to 200 miles after the change without as much as a blipp and ran perfectly, smooth changes, no surging of rpm or any usual signs of low ATF-levels.
As stated before, its my first RR, or brit for that matter as I`m used to Alfa Romeos (whole different story there).
