Hello together! My XC 90 ii D5 has 77 tkm, it is advisable to make a gearbox oil change/spülung. My question to you would be: 1: does the gearbox have a filter that belongs to identically replaced, if yes how to make the exchange? 2: Which diagnostic device would you recommend to me, with which you can make all necessary diagnostics and programming at home? Thank you in advance and best regards! Josef
