A little background. Picked up the 39 1 ton in July of 24 after a fair amount of work to get it back running, it was serviceable but pretty low compression overall and 2 cylinders real low. It had been sitting for about 10 years. One of the other issues were the transmission had a significant amount of water mixed with the fluid. That was one of the first things changed. While we were chasing "vapor lock" that turned out to be an issue with a liner flaking off in the fuel tank, the truck sat outside for the better part of a year. Fast forward to Match when I got it back and began driving it around. It would fire right up but low power and would smoke you out of the cab, so I decided to drop it off to be rebuilt as that was out of my scope. However I found a mildly built 59a motor up in PA abs decided to go that route. Motor installed with a new clutch. Drove it a couple of weeks and started to grind a little even going into first at a complete stop. Adjusted the clutch linkage a little and it shifted like a charm with absolutely not even a chirp between gears double clutching. Probably about 500 miles since this, now it's wanting to grind a lithe between 2/3 and 3/4th no problem going into 2nd or reverse at a dead stop. I don't use first with it being the granny. I checked the transmission oil and it was a little milky so I drained it and refilled with 90w gl1 (it was 140 but no one had it in stock, plan on changing again soon) However, there was a ton of water in there again. Is there some kind of boot on the shift lever that might be worn out that let's water enter the transmission? It's stored indoors or under a cover now. Secondly I tried adjusting the linkage again but can't get the grinding between 2/3 and 3/4 to subside. Any suggestions? Wondering if the water intrusion might have caused some kind of damage.

Thanks for all the help you guys give in advance.
