Toyota Repair: sequoia transmission oil, transmission oil, engine oil

Question
My son emptied thr 2006 sequoia transmission oil by mistake thinking it was the engine oil..I caught mistake before driving it..How do you add or refill transmission oil?  Thanks

Answer
There is a fill plug on the right side of the tailshaft housing, it's a 24mm size plug, you will need some sort of pump to get it into the opening, use only WS (world standard) fluid, the fluid level is critical so only put in as much as was drained out.
