I have a Yanmar 2GMF also and yes, it uses the same type of oil that the engine uses. (Not all Yanmar engines do ) There is a separate oil dipstick on the transmission. We use Shell Rotella T as recomended by the Mack Boring class I took. In our area the best place to find the Shell Rotella oil is at truck stops that service diesel trucks.
The one-day basic diesel maintenance class from Mack Boring was invaluable, highly recomended!

Yes, that helps quite a bit. Thanks for the info!

Yes, JimsCAL is correct but note that the transmission oil should not be a multigrade, use 5w. At least that is what I learned at the Mack Boring diesel class I recently took.
Hope this helps.

The transmission is separate with its own oil. The 2GM uses the same oil in the transmission as in the engine, i.e. a good diesel lube oil like Shell Rotella.

Yanmar 2GMF Transmission Oil?
Does anyone know if a Yanmar 2GMF shares its oil with the transmission, or does the transmission have its own oil?
