We probably should be comparing notes. The 4 speed in my ’41 ¾ ton comes out tomorrow. Even though it shifts fine it howls like crazy in all gears. No telling how long it had set unused before I got the truck. When I drained what ever kind of lube was in the transmission only about 2 cups of very thick black stuff came out. I refilled it with a SAE 80W90 GL-5 gear oil and put about 20 miles on it all in ½ mile trips around the block. When I drained it today it looked just like a chocolate milkshake. I think this usually means the lube has mixed with water ?? I’m pretty sure it will come out tomorrow, but I may not get it opened and apart till after the holiday.
I wonder just how much noise other 4 speeds of the same vintage make
