well it IS a synthetic fluid, if anything it should have better properties than the OEM.

In regards to Honda dealer know best, I have a story:

Some of you may know I have a thread about Honda automatic transmissions, until recently I was under the understanding that there is only an internal filter that cant really be replaced for the K24 euro, which is what Honda dealers been telling all the owners.

Only that it isn't true, there IS an inline filter, it sit on top of transmission, I even got the part number.

It wasnt' until I showed the dealer the part number AND showed them under the hood did they yield, then they tried to say it's not serviceable.... while giving me a quote for replacement.
