Replace the ignition coil. There is something wrong with it internally. It is a common problem on the 95-97 V6 models. P0725 has nothing at all to do with the transmission. It is a coil fault.
Please look at this thread: https://www.hondaaccordforum.com/m_56200/tm.htm
You should be able to do it yourself relatively easily with a 10mm wrench. If you need more detailed instructons PM me and I will help you.
It only cost me about $75 to fix. Even if you have a mechanic do it, he should not charge you more than 1 hour or so for labor as it is super easy and only held in by 3 bolts with 2 wiresconnecting to it.

Go back and tell him that with all of his experiance he was just[sm=owned.gif]by a young woman with no experiance at all! Maybe he should get off his high horse and start reading deserthonda's posts!

If his intent was to charge you thousands for a tranny, I'd report him to Honda.

BTW ---- DH is in AZ as well. I don't know if you are close to him, but I'm sure that he'd love to work with a HAF member! Also, he knows more about these cars then the designers!

Glad we could help! I am glad you got on here. If you had a new transmission put in there you would have wasted several thousand dollars and your problem would not even have gone away! I only wish you had lived nearby or I would have done the labor for you for free on a weekend.

The last honda mechanic I took it to simply "cleaned" off the dirty circuit (no discussion of repair/replacement), but the problems still remain and the light returned. They told me if the problem persists, that it "may" mean I need a new transmission. Yikes!I never got a straight answer or solution from them. Before I take it in again to someone more helpful, can someone tell me whether the issues may be related to the trouble code and whatthe actual issue may be? Thanks!
did your rpms on your cluster gauge not work either?
