My next repair job: my bucket loader leaks down with little to no load. You can see it drifting down. Replaced hoses, where should I go next.

What type valve controls loader(ind or scv)? I'll guess loader control valve is leaking internally.

Jim, how would I determine the type.

Can you post photo of valve that controls FEL?

Your loader has an independent 2 spool valve. It's possible the spool/housing are worn enough that oil is leaking between the 2 machined surfaces. To check raise loader up disconnect hose from ported hyd filter cover then remove male coupler tip & see if any oil comes out of open hyd hose over several hrs.

It appears you disconnected the correct breakaway coupling. If you remove male tip I'll bet loader boom will lower faster. There are several hyd companies that you can purchase a new control valve from such as Surplus Center & Bailey hyd's. Be sure to acquire & install in new valve a closed center plug with correct seals
(quoted from post at 14:04:53 09/23/19) Rock shaft has its own control valve. Loader has a separate control valve. and I believe your clutch is mechanical. So loader and rockshaft (3 point hitch arms) drifting down are not related since different valves control them, and it is even less likely the clutch (transmission grinding when shifting) is related since it is a mechanical issue not hydraulic. Also the transmission is not like a car transmission; you have to wait for the gears to stop turning after you push the clutch even if it is adjusted correctly.
If you don't have them you should get the operator's and service manuals for your tractor and the same manuals for your loader, they will help with clutch adjustments and such.

Have you checked traction clutch pedal for correct adjustment? It's possible clutch plate is warped or clutch plate spines & input shaft splines are rusty.
On 3 pt drifting up I'll bet friction washer on 3 pt control handle aren't snug enough to hold control handle where operator sets it.
Pictured below is a closed center adapter plug.
