The clutches are in good condition. The forward clutch drum striped the slpine. We replaced the forward and reverse drums. We also used a transmission overhaul kit to reassemble. The fluid was never burnt or had a lot of metal. We only have 50psi at idle. The manual said it needs 107psi. At full throttle we get the max pressure 200psi. When the pressure go past 110psi the clutches lock up in forward and reverse. Do we have a valve body problem? We have disassemble it and cleaned a few times and can not find any problem.
