Idemitsu Type TLS-LV (WS) ATF is an excellent alternative to the expensive Toyota WS ATF from the dealership.
I did a drain and refill for my 2013 Toyota Camry SE (4cyl) at 50k miles.
Drain oil didn't smell burnt, but it looked dirty.
** UPDATE**
Felt less smooth compared to the factory oil, I drained it out and switch back to TOYOTA WS ATF within a week. Sorry but factory one works better than the Idemitsu."
This is in contrast to many others, including many here and other forums that say that it works superbly.
