I just saw from a source that certain MDX's are going to do a software update that relates directly to the problem I had, a mild jerky feeling when driving from 20-40mph which relates to the torque converter. It's recall 12-029 from what I saw and is due to start sending out letters next month. I read that to build "confidence" in acura the warranty for 07 and other models has been extended to 8 years 105,000 miles! I hope this software update fixes the issue. If not, they stated they will replace it under warranty!
