My first experience at Water Star Motors was good. Henry and Colin thoroughly diagnosed my new noise on my 2004 Oddessey. They traced it to the transmissiion. Their recommendation was to thoroughly flush and replace the transmission fluid with synthetic ATF. The difference between them and Honda, they say, is that Honda only drains and replaces what comes out of the transmission with no flushing. This can leave bad stuff in the torque converter at a minimum. It seems to have done the trick and my transmission seems to have lost the odd new noise and is working quite well. They did charge me for diagnostics and the price for the transmission fluid flush was about 1.5x what Honda charges, but if it extends the life of my transmission, it seems worth the extra money to have the TLC that Water Star provided my Oddessey. Seems like these folks know what they are doing.
