I was thinking that might be a possible place. Theres no other opening on the top of the case that I could think of that isnt a blind bolt hole. Guess a shifter boot is in order.

Heres a theoretical question: how long does it take for 1 gallon of water to seep through the gap between a shifter and the case, from nothing more than precipitation?

Assuming (wildly) that hole for the shifer is 1.5" diameter, and a clearance betweeen the shifer hole and shifter of .05" (sloppy loose), that gives a total cross sectional area of (3.14*.75^2)-(3.14*.725^2)=.116 in^2. If the tractor is home to the Lincoln, NE region (where I live), it sees an average of 27" of rain per year. A 27" tall column of water * the cross sectional area of the gap (.116 in^2) would give a total volume of 3.127 in^3 of possible water seepage per year (not considering driving rain or ice buildup and meltage). One gallon of water = 231 in^3, so 231/3.127=73.8 years.

Now, my estimation of the total water is just a guess, and could be off as much as 30% I suppose, leaving an error somewhere between 51 years and 95 years, but the tractor is only 57 years old. I can only assume that the transmission oil had be changed at LEAST once in its lifetime, and strictly based on numerical average it would have been at the 1/2way point in its life, 28 years ago. So, since by my calculations its unlikely that water could enter at a rate fast enough to accumulate a gallon of water, either the gap is bigger that .05", its rained much harder that average during its lifetime, there is another hole where water can enter, or the tractor was at one time an experiment in submarining.
