Volvo MSB gear - ATF oil o.k.?

[Guest]

Hello everybody!

The MSB gearbox, fitted to an MD 11C, in my boat has been filled with ATF oil by the previous owner. The manual requires engine oil to be used. As I know that quite a lot of boxes (Hurth etc.) are running with ATF I am wondering wether I should change the oil?

Many thanks for any opinions

i have a volvo with the same backgear. last summer i met an old vovlvo mechanic,( my motor by the way is from 1975)and it always smokes until its warmed up. i was using mobil best grade oil. and the old mechanic told me to use duckhams green oil as that was the kind of sirup the old engines were suited to. so i reckon that applys to the gearbox as well.
