Is this a misprint or is the drain plug for the 5VZ transmission higher than the fill plug :suspicious: That's going to be one PITA drain and fill procedure...
Not a miss print it's on the far side. The illustration does a bad job at showing it though. It's a pretty straight forward task to do all the gear oil swaps I just did mine about 3k ago.
Front diff is definitely the most difficult to get to as you have to pull the factory bash gaurd to get to the plugs. Fill is still 24mm if I recal correctly but the drain has a 10mm allen head (some people say 12mm depending on year but mine fell intot the 12mm and mine was 10mm so your mileage may vary.)
For this task I recommend Redline MT90 in the Transmission, make sure it's GL-4 and Whatever reputable diff oil makes you happy. I used royal purple 75w-90 GL5 in all other gear boxes.
Open the fill before the drain always! This way you don't end up with a drained gear box and can still drive the truck to a shop to have them remove the stuck plug.
Use new Toyota gaskets!
Don't over tighten and strip them out!
You may use the camry magnetic drain plug in place of any drain plug, excluding the front diff drain plug which is already magnetic, if you wish as not all factory drain plugs are magnetic. (Part number is: 90341-18021)
Why use that plug? Here he explains it better than I can.

You will also need a good fluid tranfer hand pump.
