2005 BMW X3 Power Train Problems

IT LOOKS LIKE THAT THE SHIFTING OF THE AUTOMATIC TRANSMISSION IN BMW X3, 2005 3.0L ARE KIND OF DELAYED. I NOTICED WHILE I PUSH THE GAS PEDAL AND SPEED IS ACCELERATING REAL WELL TO THE POINT WHEN GEAR SUPPOSED TO BE SWITCHED BUT IT DOES NOT HAPPEN. I HAVE TO TEMPORARILY, FOR ONE SEC, REDUCE THE GAS ACCELERATION AND THEN IT IS SHIFTING. AS A RESULT, THE CAR DRIVES IS ON LOWER GEARS THAN IT SHOULD. THE ENGINE RMP IS ALWAYS ON A HIGH SIDE. I AM WONDERING WHAT CAN BE DONE TO RESOLVE THIS ISSUE. WILL THE CHANGE OF THE TRANSMISSION OIL CHANGE THIS BEHAVIOR. I HAVE SEEN BLOG WHICH TALK ABOUT EGS UPDATE BMW X3.
