LUCAS J. - While I agree with just about everything Vince said, especially about the cost of Hy-Tran, and the fact that when filled to the check plug on the rear cover your GD will lead a long and happy life, you could over-fill the rearend and nothing BAD would happen, but it wouldn't help anything, except maybe help you find out your rear axle carrier seals need replacing.
It's funny, but on the LARGE FARMALL's, it's common to over-fill the rearends by 5 gal of Hy-Tran or so. One of the inlet suction lines for one of the three hyd. pumps can leak air and cause all kinds of funny problems with the steering, brakes. 3-pt, & remote outlets. Adding 5 extra gal of Hy-Tran covers up the leak in the suction line and they work fine.
Ohhh. And a NEW type of Hy-TRAN will be coming to your local C/NH/IH store soon, Hy-Tran ULTRA-ACTION will replace Hy-Tran ULTRA. Same great stuff it's always been, just been slightly reformulated so it works in the Case & New Holland stuff now with NO deterioration of performance for the IH stuff. Was TEN years in the making, so lots of testing was done to make sure it's right. If you need some Hy-Tran you might get it before the new stuff arrives because I suspect it'll be more expensive. It replaces about three OTHER types of hyd/trans oils.
