This is a known condition. And, is under warranty.
Take your vehicle to a Toyota dealership. Ask them to replace your ECU per TSB (Technical Service Bulletin) TC015-07. The new ECU has redesigned logic that rectifys your condition.

You can drain and fill your trans. It will take 2.5 -3.0 quarts of DEX III trans fluid....goes in the fill tube. Or you can get said transmission flushed which changes all fluid including torque converter.....about 15 quarts. Way more thorough.
