I think the key to maximizing the life on any transmission is a good fluid with good heat tolerance. In my experience, OEM Honda fluid is NOT that fluid. I have experience with three different fluids in our Acura MDX, original Honda Z1, new Honda DW-1, and Valvoline MaxLife ATF. The DW-1, while buttery-smooth, induces some clutch slip during shifts that I don't like. You sometimes can't even feel the transmission operating, which I also don't like. Valvoline MaxLife ATF has a much more positive feel than the OEM fluid, and shifts are faster and with less sliding and gliding. The OEM fluid's behavior also changes dramatically after some miles on it, as noted by others above. It seems to get worn out quickly, and it shifts sloppy when it gets hot. It's generally just not a very good fluid in my opinion.
I normally recommend OEM fluids unless there's a good reason not to. In the case of Honda's OEM fluid, I personally think there's a good reason not to (recommend it). Many people say that Honda transmissions have a bad enough reputation already, why change the fluid? I look at it from the other direction, and suggest that the OEM fluid is a major contributing factor to the poor life in some of Honda's transmission models.
Although I don't have a lot of DW-1 in our CR-V's transmission right now, I've used it before and it seems to run better in its transmission than it does in our MDX's transmission. The two transmission models are very different, despite both being 5-speed automatics. The CR-V's transmission shifts pretty firm on MaxLife, and I've started using Castrol Transmax IMV in it.
