Assuming your transmission has a oil cooler……
Below are from “Tony’s Tip” in this web site.:

The Benefits of Fresh Water Flushing your Marine Diesel Engine

Cummins Marine 6BTA 5.9 & 6CTA 8.3 Maintenance Procedures

Also, your cooler MAY have zincs installed

From searching THIS forum, lots of info, here several hits from a forum search:

And again, the manual will have service info.

Hope this helps

Thx buddy,

Lewis,
Welcome.

More info needed:
Type/model of transmission
Hours used per month or year
Conditions used (commercial 24 hours hard work or casual)
Salt water or fresh

General answer with the above unknown:
Assuming: Recreational use, 100 hours per year

1. Get the manual for your trans, answers will be in the manual
2. Change the oil yearly
3. if in salt water, with no fresh water flush, clean the sea water side of your oil cooler.
4. Inspect/Clean or change oil filter and or strainer if equipped.

Hope this helps

Do they only come with one kind of transmission?
