First cleaned in driven about 20min, fresh gear oil chased through and always switched after until clean oil came out but before so a n dirty oil really black. Geared oil pan agreed no chips, said looks super out plug changed oil filter changed and seal everything back on oil stood optimized and finished it. And 250€ changed the owner.
