Check if your transmission computer located in the passenger kick panel under carpet. It should say AT Control Unit. Open the unit and look for burned resistors or capacitors. If you noticed a burn spot, replace...if not its better to take it to the Honda dealership and get a diagnostic.

It sounds like the valve block, propably the2-3 shift valve is fluctuating , possibly worn. or a weak spring.
You would need to remove, open and check the valve block.
Has the ATF been changed recently ? because that could cause it. New oil could flush the valve block so its very clean , removing any debrit ,and then it loses its integrity
