What symptoms are you having? Usually not much goes wrong with TCV o rings relief valve spring broken.

Well I was able to hold the tractor in place by putting it in forward or reverse and then holding the fenders. And then I played with the Detent ball or what ever you call it and it has more power as in it will pull m e around but still not the power that it should.

I asked on another forum and someone said it was in the gear box so I opened that and everything looks good. The hi and lo feels the same as our low hour 220 and out 155. I am just guessing it's the tcv but I could be wrong. Like I said above I just played with it a little and it gained a little power but I better the 220 could drag it around.

After reading the stuff you sent me gopher I think I need to re look at the relief I had it out today wad it only had the acorn nut and screw. I'll tear it down again to morrow and see if it's missing parts?

Ps after today's tear down it looks like someone was inside the tcv but could be wrong
And if that checks out she's going to rehab at the case dealer.

Can you get the lift circuit to squaw the relieve valve?  could be pump going bad. You might check the spring length if broke and po took part of it out that would keep the pressure down.
