Got a quick question, but first the facts: 1953 3100 with original 3 speed transmission and torque tube. I've just reinstalled the transmission in the truck and need to fill it with gear oil. There are discrepancies with the hard copy shop manual and online manual, due in part to different editions. My hardcopy manual states removing a pipe plug to fill the universal joint. The only pipe plug that I can see is forward of the u joint and would fill the main case. There is a hex head bolt/plug by the u joint. Is this the u joint fill location? Also, does the transmission really only take 1.5 pints? I thought you filled until the level was close to the fill plug opening....
