Is the pressure line from the pump feeding the remote control valve dirrect with a relief valve between pump and valve? Where does relief valve dump to? Is return outlet of remote contol valve going to the pressure inlet of the liftall unit?
May be wrong on the guess, but guessing when the pressure builds up on the return outlet of remote control valve when using the liftall it pushes the spool up and then you're dead headed with no place for presure to go but the relief valve.

that is what is happening... thats why i was wondering if the christmas tree valve not being centered exactly is causing it to happen, or it will happen that way regardless of position. if it will happen anyway i'm thinking a check valve on the return side of the christmas tree valve would fix it... do they make one for hydraulics?
