Automatic Transmission Torque Converter problems of the 2009 Acura MDX

I took my 2009 Mdx into Acura dealer for shudder at 35-45 mph at 68k. Service tech wrote up repair order as pcm update. They did not document the shudder complaint. Even tho I drove with service tech and then he drove also, verifying shudder. I had to go back 2nd time as pcm didn't take according to dealer and thats why shuddering continued after 1st pcm update. Now at 107k, shudder is back. Mdx out of extended warranty by 2000 miles and Acura/Honda refuses goodwill repair. This is my second Mdx. The torque convertor needed replaced in my 2003 Mdx. Acura assured me when I purchased the 2009 that this known problem was resolved. Obviously the torque convertor/transmission continues to be faulty. I'm wondering if the pcm update is disguising the problem pushing the Mdx past the mileage warranty.

I brought the car into the dealer because I was having transmission problems or power steering problems. I indicated that the car makes a whine at about 1500 rpm. The dealer chose to treat it as a power steering problem. The power steering pump was replaced. There was still a whine although less. The car rpm hangs up on deceleration to a stop. Some times when going down hill the car does not upshift until the car is accelerated even though the road slope is zero. The dealer never informed me when I brought the vehicle in for the original concern that there were some problems with the transmission or torque converter hanging up.
