Massey ferguson transmission oil spec

[Ferguson165]

transmission oil spec for 8120 looks to be MF cms m1143/1144
Is it same as MF m1143/1144?
Just wondering because some lubricant advisors show 10w-40 STOU or should UTTO be used?
Can STOU be used in 6465 transmission as well?

Off the top of my head but can't remember which way round MF 1143 and 1144 one is a specific trans oil (Shell Donax) the other is a STOU which can be used in the engine and trans (Shell Harvella)
Again off top of the head, once you have the right transmission oil for the 8120 it will be good for a 6465 too. The engine of the 6465 may require a better oil than the 8120
