[C320-list] Transmission lubricant

[Jack Brennan]

Because I’m retired and sail 12 months a year, usually with one or more decent trips (pre-covid), I probably put 250-300 hours a year on the diesel. An ounce or so a couple of times a year is needed to keep it full.

Oil on these types of transmissions usually will stay fresh for years and years. If it turns black, something is wrong.

I like to change mine when I change my engine oil, which is every Fall.  I
use ATF oil rec'ed for a Perkins, and it's very reasonably priced, given
how little my trans takes.  Figure it's a good time, since I my vacuum pump
is right there.  But know I'm prob changing my trans too early, as I only
put about 30 hours on the iron genny a season, but like to err on side of
caution with my engine, and get any moisture out early, as well as force me
to check the trans fluid level.  Might be a stupid question, but there is
no harm in changing the trans fluid that often, is there?
