wow a 4cyl 6th gen with tranny probs....i guess the AV6'ers aren't alone.

fight it, and get them to pay you instead another stock tranny get a levelten tranny which should be indestructible.

you've had multiple repairs under warranty. this part should still have some warranty on it. and this is not regular wear and tear. will you win? not likely, but because honda is doing this whole customer service improvement initiative they may be much more willing to listen to you. honda dealers are notorious for poor service and honda realizes this. use it to your advantage.
