I have a '06 Rancher, but it is a 350 FE. I have had zero problems.
My neighbor has a AT 400, but I think it is a '03 or '04. His tranny will slip after it heats up from pushing snow for over an hour or so. I have heard of others with various year 400 ATs having slippage problems if the fluid level isn't kept completely topped off.
It sounds like you are having a different problem, but it is still with the tranny. As long as abuse or neglect isn't involved, Honda should take care of it no questions asked.
