I see you're a night owl too.

Yes, I opened a small drain plug on the bottom of the transmission (I'm assuming since it was just behind the front axle) and it is slightly milky. Maybe this is not hydraulic fluid - sorry if it's not. The hydraulic fluid is also even "milkier" when I disconnect one the FEL hoses and operate the FEL. And yes, the dipstick I checked is the one at the rear of the tractor. I was just trying to give all the info I could about what I'm finding on my tractor to see if it helped give anyone an idea about the cause of the loss of transmission power. I thought maybe the milky hydraulic fluid is related to my transmission problem. Maybe it's a pump or a clogged filter or screen. I just don't understand why the hydraulic fluid is milky at the front of the tractor but clear at the rear of the tractor. It's like it is not getting circulated but maybe this is normal.
