Oil type for gear box on Sole Diesel?

[sailor Martin]

Hi

I just bought a boat with a "Mini 34" and a shaft drive.
Does anybody know which oil goes in the gear box?
The manual doesn't say. It only reference to the cranck case oil. Also, ex owner isn't co-operating..

Cheers

My mini33 has a tmc40 p transmission. It uses dex 3 automatic transmission fluid. If you can find out the transmission it has, you should be able to figure out the oil.
