The ZE Corolla requires an ATF that meets or exceeds the Toyota T-IV specification.
The key to transmission longevity is regular service.
Toyota recommends a 100k km replacement interval, IIRC, which is plain ridiculous.
A drain and fill every 20k km should be fine in T&T conditions.
I actually drain and fill every oil change, which tends to be about every 10k km. And yes, I use synthetic.
