RECENTLY PURCHASED 06 MDX. DIDN'T NOTICE THE TRANSMISSION ISSUE RIGHT AWAY. ABOUT MONTH AFTER PURCHASE, I NOTICED SHUTTER/GRINDING/JUDDER/WHISTLING COMING FROM THE TRANSMISSION. TOOK IT INTO ACURA DEALER. ACURA REPLACED TORQUE CONVERTER AND UPDATED PCM SOFTWARE UNDER WARRANTY. ABOUT WEEK LATER, STARTED NOTICING THE SAME SHUTTERING NOISE COMING FROM TRANSMISSION AGAIN BUT ITS NOT AS NOTICEABLE BUT DEFINITELY NOTICEABLE AND THE PROBLEM IS STILL THERE. ACURA DID NOT "FIX" THE PROBLEM. IT SEEMS ACURA HAD FIXED THE "SEVERITY" OF IT TO THE POINT WHERE YOU CAN ONLY SLIGHTLY HEAR IT. AFTER BEING THOROUGHLY FRUSTRATED WITH THIS ISSUE, I STARTED RESEARCHING THE INTERNET AND FOUND OUT THERE ARE MANY MANY MANY MANY OTHERS WITH THIS SAME PROBLEM. IT SEEMS THAT THERE IS NO PERMANENT FIX. NUMEROUS OWNERS HAVE SAME REPEAT PROBLEMS EVEN AFTER REPLACING THE ENTIRE TRANSMISSION. THE PROBLEM SEEMS TO BE THAT OF A "DESIGN" OF TRANSMISSION ERROR BY THE ACURA SO ESSENTIALLY, ONLY PERMANENT FIX WOULD BE TO REPLACE THE TRANSMISSION WITH THE NEWLY REDESIGNED TRANSMISSION. IF YOU REPLACE THE SAME PARTS OVER AND OVER, YOU WILL HAVE SAME PROBLEMS OVER AND OVER. ACURA FAILS TO ACKNOWLEDGE THIS. IF YOU TAKE THE CAR TO ANY ACURA DEALER, THEY WILL VEHEMENTLY DENY THERE IS TRANSMISSION PROBLEMS(I AM SURE THEY'RE TRAINED BY THE CORPORATE TO DENY, DENY, DENY). UNFAIR. ESSENTIALLY, MY CAR IS A "LEMON" ALBEIT A USED LEMON....
