    ‘64 4020D Syncro Hydraulics

    Sorry, I tried DS and that didn’t work. I was referring to what appears to be the round access point just behind transmission filter. I assumed that was the long screen. It appears to have a larger than 3/8” Allen hole in center. Am I looking at wrong access point for screen?

    68/64 4020 Syncro

    Thanks red, I think you are correct re: shifters. I actually got axles turning in all gears except entire 2nd range is dead. 4th (I think 2nd range) actually seems to bind/grind. I wish someone had a pic of exact orientation of cam and top shift lever in park (the normal stopped position)...
