A Corolla transmission that has the transmission oil pan removed to get all the fluid out and debris cleaned out and the fluid changed every 30k will last 300k without any need to "flush" the transmission with a flushing machine.
You need to read this article . I learned about why not to "flush" and the fact Toyota uses specif fluids.

Recommend changing the transmission fluid and filter every 30,000 miles under normal conditions
