I wanted to wait and call Acura to see what they would say. Since it was a weekend I had to wait until Monday. Well I called acura today on 10/12/09 and stated the diagnostic code they said that they have that part which is the 4th pressure circuit and it goes for around $70 bucks and is located on the trans axle itself rather than inside the transmission housing. I will go from there purchasing the part from acura and see if that fixes my problem. I appreciate the time and help. I will respond later if it fixes my problem.
