I HAVE A CAT D4G TLX00664 WHEN I PUT IT IN PARK THE LEFT TRACK WANTS TO CREEP FORWARD, BUT WHEN I TURN PARK BRAKE OFF IT STOPS . I HAVE NO CODES SO IM THINKING ITS HYDRAULIC ISSUE. I HAVE CALIBRATED ALL ELECTRONIC COMPONENTS SUCCESSFULLY. TRYING TO FIGURE OUT WHERE THE BYPASS IS COMING FROM? PUMP OR DRIVE MOTOR? HOW DO I GO ABOUT TESTING EACH, IS THERE SOMEWHERE IN SIS I CAN FIND THESE PROCEDURES? THE RIGHT SIDE IS ACTING FINE LIKE IT SHOULD.
