Toyota Genuine ATF WS only. The reference capacity is 11.3 qt.
That is the footnote under the capacity. This page does not add a drain procedure.
Power steering is DEXRON II or III. Transfer and differential oils are hypoid gear oil, not ATF WS.
The transfer case, on 4WD trucks, is Toyota Genuine Transfer gear oil LF, SAE 75W: 1.1 qt on part-time 4WD and 1.5 qt on full-time 4WD. The front differential is Toyota Genuine Differential gear oil LT 75W-85 GL-5: 1.6 qt part-time and 1.5 qt full-time. The rear differential is the same gear oil: 2.9 qt without a rear locker and 2.8 qt with one. None of those is the transmission.
Engine oil is on the oil guide.
