You may have paid more but prob worth it since they work on Toyotas all the time. I’d have them do a full fluid exchange this time. A transmission expert on here recommends doing a drain and fill first then doing a full exchange. So you’re doing things fine. Dealers here charge from 250 to 300 so shop around if you want. You can prob go 60k on the next interval.Can I ask what the typical cost is for a shop to do a drain and fill? Since I took mine to a dealer, I have a feeling I paid more than I had to if I had taken it somewhere else.
