CVT whine

Most days when traveling the 38 miles it takes to get home, if I drive more than 65mph on the interstate, the CVT gets really whiny by the time I'm in the last mile or two. Does anyone think a larger transmission cooler or adding a transmission cooler might be a good idea? I'm just thinking that if it is struggling that much to make the car go...even under normal highway speeds...that cooling things down might help out? I'm not getting any ecm/transmission codes, so I know its not overheating. Perhaps the "gear" whine is normal. Thoughts?

I started hearing a whining noise from my CVT at about 40K miles. Changing the fluid fixed the issue. I'd say the change interval should probably be something like 20 to 30 thousand miles.
