I have what i believe is a Fuller 5C650 transmission in my 1957 Howe Defender fire truck. Does anyone know were I can find information on it? Service manual? Operator's manual? What fluid should I use? Fill/level location? Any other useful information.

SAE 50 or 40 engine oil will see you right. Should be a pipe plug on the side of the trans, fill to bottom of hole. GL-1 90 could also be used.
