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 just had a fluid change done at 96000 miles at the dealer for $250 and I haven't heard the whine since. It would whine only on hot days, and my Suzuki SX4 had the same whine when it got real hot.
