I HAVE A 2000 TC33 GEAR DRIVEN. THE PROBLEM I AM HAVING IS THAT THE 3PT HITCH DOES NOT LIFT UNLESS I USE THE LOADER STICK AT SAME TIME. IT DOES LOWER WITHOUT ANY ISSUES. THE LOADER WORKS FINE UNLESS 3PT HITCH IS IN THE UP POSITION AND MAXED. THE POWER BEYOND IS IN THE RIGHT SETTING AND WAS TAKEN OFF INSPECTED AND CLEANED. TRACTOR DOES HAVE REMOTES NO BACKHOE. ANY IDEAS ? THE FLUID IS FULL AND THERE ARE NO LEAKS. SOMETIMES THERE IS A WHINNING NOISE WHEN USING THE LOADER. GOD BLESS !

Roger, I think your "power beyond plug" in your loader control has become loose and is allowing fluid to bypass back to the reservoir instead of going back to the 3PH. Only when you use the loader will enough back pressure be generated to allow the 3PH to operate. Even when it operates, I'd bet the 3PH doesn't have a lot of lift. In the picture below, I've shown a photo of my loader control valve. Circled in green is a plug you remove for access to the Power Beyond Plug. That plug will be an Allen-head plug and will be loose in the cavity. Use an Allen wrench to screw the plug back in and re-install your cover. I'd bet that's all it will take to return full functionality.
You didn't say, but is your loader the 7308 or the 14LA? It shouldn't matter. Both have a similar joystick valve that may not be exactly like my photo, but it will be close enough to locate the plug.
EDIT: Oops! I see now that you said your tractor was a 2000 model, so that means it is a 7308 loader if it is New Holland. Even if the loader is not New Holland, it probably has a power beyond plug that is similar.

WELL I REMOVED THE COMPLETE LOADER CONTROL VALVE ASSEMBLY .CLEANED IT UP IN AND OUT AND REINSTALLED IT .I ADJUSTED THE VALVE YOU RECOMMENDED. I AM STILL HAVING NO LUCK. ALSO WHEN THE 3PH DOES LIFT WHEN I MOVE THE JOYSTICK AROUND , IT HAS LOTS OF LIFTING POWER AND SPEED. ANYTHING ELSE I CAN TRY OR CAN ANYONE OUT THERE PLEASE HELP ! THANK YOU !
Rogerr, was this tractor working properly, then the 3pt stopped working? Is it new to you, and always been this way? Was some work done on it, now the 3pt won't work?
From what I'm reading, it almost seems like the PB and T ports on the valve were switched.

BOUGHT THE TRACTOR LIKE THAT. DEALER SAID THEY BELIEVE IT WAS THE POWER BEYOND VALVE UP FRONT BY PUMP. SO I COMPLETELY REMOVED/ CLEANED IT UP WITH NO LUCK .THEN COMPLETELY REMOVE LOADER VALVE CONTROL AND CLEANED UP.STILL NO LUCK. I AM STUMPPED.EVERYTHING LOOKS ORIGINAL ACCORDING TO NEW HOLLAND MANUALS. I DONT SEE A LIFT SPEED ADJUSTMENT ANYWHERE. ANY HELP WOULD BE APPRECIATED. THANK YOU.

To go along with what Jbrink64 said, has someone changed the position of your diverter valve? That's the valve they use to route hydraulic pressure to the joystick before it goes to the 3PH. If the diverter valve is rotated to the wrong direction, it puts the joystick in parallel with the 3PH instead of in series as it should be in an open-center system.
EDIT: Roger, you asked me about the location of the diverter valve in a PM. Here is an illustration attached. Your diverter is directly behind your main hydraulic pump. It's item #2 in this illustration.
EDIT2: I added a description of the diverter on my tractor. Your's is similar, but not exactly in the same location as mine.

If you look at the diverter valve, there should be 3 lines attached to it that go to the loader valve.
The top left port connects to the loader PB port. The port on the right goes to the loader valve P port. the port on the lower left connects to the loader valve T port.
I would make certain they are hooked up this way.
If the PB sleeve failed in the loader valve, the 3PT would'nt work at all. If the diverter was in the wrong position, the loader would only work when the 3PT was under pressure.

Outstanding! Jbrink64 did another great job of analyzing this and figuring out the lines must be reversed.:thumbsup:
