John Deere 410 Backhoe won't go forward

Hi Everyone
I have a problem with my John Deere 410 backhoe that I bought and it?s not moving forwards but will move in reverse? the backhoe and loaders hydraulics seem to be quick and working good from what I can tell. Here is what I have do to try and fix this problem? I tested the hydraulic pressure in ports # 29 & 31 in the reverser clutch valve assembly and reverse was 100 psi. & forward was about 25 psi. and I did check the pins in the leakage going to the reverser clutch valve and it was ok so I took off the reverser clutch control valve assembly and took it apart cleaned it and there was no valves stuck or sticking so I put it back together with new seals and I pulled the sump screen out and it was mostly clean so I ended up splitting the backhoe because I?m thinking it?s the forward clutch pack now. I found out that a c-clip was broke on the forward clutch drum and the clutch disk & plates were warped and burnt up and part of the gear was stripped from the clutch disks so I replaced all that and put new seals in the forward clutch. The reverse clutch disk and plates look new so I didn?t change them? Checked the dry clutch and it looked good so I put everything back together and changed the 2 hydraulic filters and put new john Deere hydraulic fluid back in. I started it up and put it in reverse and the backhoe moved in reverse but it still won?t go forwards so I checked the pressure in the reverser clutch valve again and reverse was 100 psi. And forward was 100 psi they should be about 165 psi. So now I?m not sure what to try or look for I thought maybe after fixing all that it would be good to go. Not in my case.
Any help or advice here would be greatly appreciated on what you may think it is or why I still have only 100 psi pressure or why it won?t go forward I?m wondering if it could be something back behind the transmission in the rear end but that still won?t justify for the low psi in the clutch control valve. I?m stuck here guys? I need some great advice here now. Thanks in advance

Make sure the "clutch pedal"linkage is adjusted correctly. The clutch control valve is basically a dump valve that reduces pressure to the forward/reverse clutches. Very little movement of the pedal, or too tight a setting will begin to reduce pressure.

Thanks for replying back to my post' I will check that out tomorrow.
Thanks again

OK I took a look at the clutch pedal linkage today and it was a little tight so I backed off the adjustment and tried it again with no luck. I had the gauge hooked up to the forward test port and it only reads about 60 psi with the clutch pedal all the way up and when I just started to push the clutch pedal down the psi dropped down to 0' That is the way it is supposed to work isn't it. I really don't know how the hydraulics work and I wish I did so I could understand them. I know it should be getting about 165 psi but it's only getting about 60 psi where is the other 100 psi going. Any other suggestions what it could be or what to look for.
Thanks

I'm thinking on changing all the springs in the reverser clutch control valve assembly to see if I can get the pressure up on the forward port and may be add some shims but I will try new springs first' I just ordered them so waiting for them to come in. Does anyone have any other suggestions because I'm running out of things to check and I need to get this frustrating machine going. Thanks
