THE LEAK CAUSED BY A DEFECTIVE SEAL WAS MEARLY A MANUFAC PROBLEM AND A REVISED PART IS BEING PRODUCED/ SUPPLIED. AS FOR THE THOUSANDS OF TRANSMISSIONS BEHIND ALMOST ALL V8 MBZ'S THE REPLACMENT/ REMAN UNITS WILL FAIL AS WELL. MY GOOD FRIEND (PARTS)AT FLETCHER JONES IN NEWPORT BEACH TELLS ME ABOUT THE CRATES OF TRANSMISSIONS EVERY WEEK. EVERY NEW MODEL BMW WILL SUFFER SOME SETBACK THATS WHAT HAPPINS WHEN YOUR PRODUCING THE WORLDS MOST ADVANCED CARS. THE SAME HAPPINS IN EVERY INDUSTRY.
