Transmission Noise problems of the 2005 Acura MDX

This is the second transmission I put in my car , warranty expired and car is starting to jerk and make noise when accelerating. It cost way to much money to keep replacing a transmission if all the transmissions are having the same problem . Way to many people are having this issue . Why hasn't this been recalled yet?.

Transmission starting making a grinding noise around 40 mph with ~70k miles. At 96k, the car broken down while driving at highway speeds. Dealer has indicated the transmission needs replacement at estimated $4k, but can't currently find a replacement or rebuilt one available.

The contact owns a 2005 Acura Mdx. While driving at approximately 30 mph, the contact noticed a grinding noise in the transmission when he depressed the accelerator pedal lightly. There was also a pulling sound coming from the transmission area. The noise continued until the accelerator pedal was depressed harder or the vehicle slowed down. The vehicle had not been inspected at the time of the complaint. The failure mileage was approximately 53,000. The current mileage was approximately 54,500. Updated 07/29/10 updated 08/03/10.

I have a 2005 Acura Mdx touring model which is making grinding noise which seems to be transmission related. This has been going on for about a year. I asked my mechanic to check it and he could not come to a remedy. I have read of other 2005 Acura Mdx owners finding the same problem which means it is systemic/manufacturing flaw. This is an ongoing problem. I use premium gasoline so it isn't anything related to low grade gas. It is a loud grinding sound that happens when the car is just starting to get going, around 20-25 mph and if I slow down and accelerate again. I am sure it will continue to get worse. I also had the catalytic converter shield checked to make sure it wasn't loose and rattling and it was ok.
