Thanks, jzchen, for the advice. I bought 6 quarts of the Valvoline CVT fluid at my local Walmart. The Toyota dealer's receipt said they would deduct 20% from my refund for a restocking charge but they ended up not charging me. Since they treated me fairly I ordered a replacement passenger side mirror light that was broken. It arrived a couple days ago so I'll be fixing it later. Now I'm shopping for a reasonably priced transmission filter. The cheapest I could find on eBay is $60! Most transmission filters for other cars are priced from $20 to $30. I'll get a price from the Toyota dealer shortly.
