Our hydro is acting up in our 656. The drive pressure starts jumping at around 4000 psi. It will pull itself forward and reverse in low range but has no draw bar pulling ability past that point. In high range It just vibrates the wheels and sounds terrible. THis occurs in both forward and reverse at any RPM. We have changed oil, servo valve, and foot&inch valve.

Any insight to our problem would be greatly appreciated.

thank you,
Brad

You almost need to flow rate a hydro to determen problems could be just the charge pump

If you have to rebuild the hydro, better sit down==about 5 g"s

we had the hydro apart but everything looked real good in there. We found a bad seat on the servo valve and thats about it.
