    Hello PriusChat,

    Here's a video of the 3rd Gen. Prius transmission drain and refill, pretty simple to do but time consuming. So here it is!

    As simple as that? Might give it a go sometime. What was the specs on the transmission fluid you used? I see it was Toyotas own.

    we used 5 quarts just so we can pump it till it drained, but its usually 4 quarts and a little extra fluid because the other bottles had remaining fluid in them. The fluid we used was Toyota ATF WS.

    Nutz, We need to pin a medal on you for that presentation! Well done and a pleasure to watch and listen. As I watched, I thought my biggest problem would be remembering where all of the clips and bolts go when replacing the under body panel.:(

    Could you comment on the oil that you drained? I assume it had around 30K miles on it and it appeared to be relatively clean. I understand the object is to change it before it looks like tar. Also tell us about the pump that you used, as I haven't seen one like that.

    We all appreciate your time and a pat on the back for your cameraman!

    A funnel with a extender hose added can be used from above. It's a little simpler, easier and less expensive.
    Also it can be done from the oil change door, you don't have to remove that whole panel.

    I had an oil analysis done on the ATF I drained from a Gen3 with 112K miles. I bought it with 108k.
    It was really bad. To see how bad ATF can get, go to this thread:
    ATF fluid changes ARE Required. | PriusChat

    It's a bit wordy, but just look at the oil analysis reports and the pictures of funnel/hose I used.
    Also at ATF change time is a good time to add a magnetic drain plug. You can buy plugs with the magnet or make your own.

    Thanks Nutz for the video showing how easy it is to change the trans fluid. It should give confidence to DIYers who were unsure about whether they could do it.

    Like Bill Norton said, there's a link to the thread about the oil analysis he's done on it, as for my transmission oil, it was a maroon color when it was drained. As for the pump that we used, it was a mityvac fluid transfer pump P/N 07240, you can google that online and it'll show up. Also like bill has said, you can use the funnel and an extended hose. I've never done this myself but I assume it works since people have been using it.


    Hey Bill, I believe for the 2010 Prius, you don't have to remove the under panel, but for our Prius 2012, the under panel is different maybe, because I checked underneath, and there is no way you can reach the drain and refill plugs without removing the under panel. Just FYI, maybe there's a reason why the 2010 Prius has the under panel recall, who knows, but for the 2012, there is no way I can see to drain and refill without removing it.


    yes this will help tremendously for all the DIYers.

    Look at the pic of the tools I used. There is an 18" , 3/8 drive, extension with a 10mm allen socket on the end.
    I looked and the oil change panel has not changed in size, just in strength with the new/recalled access panel.

    But, by removing the whole shebang, you get to see everything and do a proper inspection of the area.

    Good job on the video!

    well, I gotta give you props for doing it without taking the plastic under panel off. We were having a hard time breaking the drain and refill bolt loose with just a 3" extension and even then, we almost injured ourselves lolz. So whatever works, works right?

    and thanks for watching the video! it was fun doing it, only painful part was the clean up haha...

    Somebody should come up with a simple kit for this to sell on ebay (so it's available to international drivers too). Even if they don't provide the oil, just the pump, hoses and instructions.

    I'd buy it.
