TC45DA 3 point problem

[2Buckslake]

I have a 2006 TC45DA tractor with hydro trans,16LA loader, 1230 hrs. I having an issue with the 3 point when lifting an implement, etc. It will pick it up, somewhat slowly, and then when you set it where you want to stop it height wise, it will start to go down, and then it tries to pick it up to where it was, and then do it again. Kinda like a bucking motion, up & down. Now sometimes when it does this I can move the three point lever back & forth, & it will stop doing it. I have been very religious replacing the trans fluid & filters at the correct intervals. I read a post where there is a pipe plug in a valve under the boot for the joystick that backs out, I checked that & no problem there. There is another valve under the floorboard with a similar plug in the bottom of it, does this have a similar problem too? Or, is it a problem with a valve inside the trans that the 3 pt. lever is hooked to. I haven't had many issues with this tractor since I bought it new, but I'm puzzled which direction to go. Any help would be appreciated...

Try putting some oil on the feed back linkage.

Sounds like it's starting to hiccup. I have the same tractor and it had similar symptoms a few months ago. It's the seals in the 3 point cylinders that need to be changed.

Here is a link to a thread I started on the same issue. http://www.tractorbynet.com/forums/hydraulics/353705-3-point-hitch-hops.html

And here is a thread on a similar issue someone had on a different tractor. http://www.tractorbynet.com/forums/century-branson/361051-3-pt-bouncing-bleeding.html
