This information on the Gen 7 V6 Accord has been gathered from forums, technical publications, talking to service centres, transmission rebuilders, Mechanics and serviceing my own vehicle. There's a wealth of information to be found but it's scattered all over the place, some of it incorrect. I decided to bring a few of the pieces together for my own use and reference and share with other DIY owners - do your own research and be informed.
Honda Motor Co. widened a recall of vehicles in the U.S. and Canada to 1.14 million units, among its largest.
Unfortunately, prolonged torture testing for reliability of this gear set wasn't long enough and internal lubrication and cooling weren't discovered until many people owned vehicles with these ill-fated transmissions in them.
I decided to perform my own valve check and adjustment as the dealer charges are high for this service, and I no longer trust the dealers to actually check or carry out this work correctly.
It's sad that it has come to this with dealer service, and service in general, but recent experience with arrogance and incompetence by some of the Honda dealers and service industries in general has led me back to DIY.
