your vehicle is talking to you ..here is what it is saying ,,,will you please give me some new transmission fluid foreign blend and a new filter ...about $65.00 do it yourself

in the side of the tranny big plug going in to it

I doubt it was new. If they wanted your old trans, it wasn't new. You can always get the part number and ask the parts guy to check that number, but that's not the issue today, what is P0730 indicating? have it checked by Honda or a good trans shop.

Thanks for choosing FixYa and welcome to the site. I would advise you to have your transmission checked as soon as you can. You might need to check your fluid and change your transmission filter first to see if that helps. But, more then likely, your transmission will need worked on since it slipped. That may be just the beginning.

Two common problems are: (1) trnsmission modulartor may need to be replace. (2) Carburation setting may be off in your idling, Oh don't forget the fluid levels make sure!..

You need to get serial number off radio. then either take to honda dealer for free if this website dont help.

Internal trans failure, Trans would have to be rebuilt.
