MF 65 Gear Slipping?

[SaveMy50]

MF65 276 Gas. Feeling/hearing an internal gear slip, like a binding and slip. Heard first on field, mild slope uphill, while baling with NH 273. Then mild slope downhill, just driving no load or hauling, and now hear/feel once in while. Axle? Don't think it's PTO related as it happens no load.
I know it needs clutch adjustment/replace, power steering fix, and carburetor adjustment, but they aren't related to this issue.

Six speed, or the 12 speed transmission? Gears don't just slip, but the clutch can.

Six speed transmission. The clutch has been going for a while, really hard to engage PTO now, but gears don't shift that bad, didn't think it was clutch related, but I'll try and listen more closely, as I thought the sound was behind me?

Really only the right side sounds like it slips. I have the manual, so guess I'll be pulling the axle off (this winter)?

There could be something wrong in the planetary. They have their own oil and don't get lubed by the transmission, and are often neglected. I'm not sure if a
failing bearing could do what you're hearing/feeling.
