Last job, service the transmission - need to know:
What oil goes in the gearbox and final drive, manual hasn't got me convinced. Manual appears to say to put ATF in manual gearbox ... (quietly hides in cupboard)
Gearbox: yes, it is ATF:) You can use Mobil 210( if you can find it, NLA), or any ATF type F or G, if I remember it correctly. Also there is original volvo oil: 1161647 or 1161547
Final drive: any hypoid oil GL-5 category, viscosity 75w-90 or 80w-90
