Can anyone tell me if the transmission oil and differential oils are the same?  I can't find  check plug in the side of the transmission.  There is a dip stick in the differential (rear end) in front of the seat-  is this for the differential and the transmission    Need to know if they use same oil.  Any help would be greatly appreciated   Restoring a old machine that was headed for scrap.  Have it running but do not have a manual   Thank You   Gene Horner  2602512278
