T&T: twin disc lubrication plate

[Quince]

I too did not have any lubrication plates on my transmissions but I just
found one in the spare parts bin.
 
Mine take 1.7 gallons and are 1991 vintage behind 3208 Cat's
 
Here's what the plate basically says:
 
>>>>>>>>>>>>
 
MARINE TRANSMISSION LUBRICANT
 
OIL SERVICE CLASS - USE SAE-API SERVICE CLASS CD ENGINE OIL 
CERTIFIED BY VENDOR TO PASS TC-2 OIL TEST
 
ALSO APPROVED ARE SAE-API SERVICE CLASS CC ENGINE OIL MIL-L-B AND
TRANSMISSION FLUID TYPE C-3
 
VISCOSITY - BASE SELECTION ON SUMP TEMPERATURE
STARTUP - 32 DEGREES MINIMUM
RUNNING - 150 -185 DEGREES USE SAE 30
    OR        - 174 - 210 DEGREES USE SAE 40

Hope that helps
