Real dumb question

I have a 1960 Ford 861 Diesel and am wondering what kind of oil to put in the box where the gear shift is. I warned you that this was a dumb question.
 
Although the original specs say 90 weight gear oil, it will shift smoother in cold weather if you use New Holland 134 or equivalent universal hydraulic fluid. And if you use the same in the differential, there's no possibility of contaminating the hydraulic reservoir (between the trans and diff) with gear oil.
 
As per current New Holland recommendation, I use CNH 134D in all sumps (except engine) in all of my ventage Fords.

If you honestly don't know the answer and would like to, "The only dumb question is the one you're too timid to ask." We're glad to try to help, and like so many questions/answers, there's no "one size fits all" to this one. First, make sure the cotter key in the hole under the bell housing can move freely. Then, if there is seepage of transmission lube coming through that hole when the tractor sits, and you don't want to split the tractor now to replace the transmission input shaft seals, use gearlube. The same holds true of the differential fluid, with regards to pto and rear axle seals on these tractors. When they are marginal, it can make the difference of minimizing as opposed to maximizing the leaks.
