Take it to a parts store (like Autozone) and have the code read for
free.
It could be as simple as a vacuum hose on the filter housing (then MIL
could show loose gas cap related codes) or many RX300 of that
generation suffered from "Shift Solenoid E" failure. In which case
the condition of the ATF will be poor (burnt, dark etc). That's around
$5000-6000 problem. The U-series are not the most reliable
transmissions.
