No Maintenance for the AT?

[erhayes]

I reviewed my owners manual and I can't find any service interval for the AT. Strange that there is no recommendation in the 07 or 08 manual. i usually go the first change at ~ 20,000 and the every 40,000 after the first change. I suspect it is an oversight since they don't even say "never" or "good for the life of the vehicle". Comments? Ed
