    Hey! I'm trying to change my trans fluid on my 2010 Toyota Prius I, but I go under there and look, and there's NO drain plug and NO filler plug! It's just completely solid, with a black electrical thing on the front (looks like an electric pump or sensor of some kind). I've watched videos, read articles, read manuals, and you guys are my last hope! I would just hate to have to take it in to the same dealer who's telling me "it's good way past 100k miles... blah blah blah..." .

    Any references to other resources or threads would be sooo helpful. Thanks everyone.

    So these are the only two plugs I found, both facing the rear of the vehicle, on the drivers side, by what appears to be some kind of driveshaft and stablizer bar...

    Are these the drain and fill plugs?

    Thanks.

    I have attached an excerpt from the repair manual.
    The view is from the right side.
    The circle to the right of the filler plug, directly above the drain plug, is the right drive axle.

    There is a thread with photos, but the images are not appearing at this time.

    So from what you're saying, I think, the thing I'm pointing at with this red arrow should have a black boot on it, with a large metal shaft sticking out from that? Some kind of driveline/driveshaft?

    This is looking from the passenger side towards the drivers side. The drain plug is at the 6 o'clock position, the fill plug is at the 9 o'clock position just to the left of the cross shaft. Both the fill and drain plugs are the 10mm Allen head bolts. I just did mine yesterday, as recommended by others in the threads linked above before you drain it make sure you can get the fill plug out.

    I guess that image isn't coming out right for some reason... been seein updates to the forum so maybe that's it, but I used Photobucket to get mine on here. Worth a try to help a fellow Blizzard Brigadier? :D

    I see it now. Thanks. That's exactly what I needed to see... SO, TOYOTA o_Oo_O .... wanted to play HIDE and SEEK, huh? Thankfully, we have a great community here! I guess too many people were doing their own transaxle fluid changes and NOT buying CVTs from GenI and GenII :censored: ... We gotta fix that straightaway! :sneaky:

    Great Job! How many miles were on the car when you changed the fluid?

    Hehe, I did what you did and left the fill plug out when I unscrewed the drain plug, fluid gushed everywhere! Next time I won't forget to leave the fill plug in and get a nice controlled stream. I changed mine at 84k miles and my fluid didn't look as bad as yours as it still had a reddish tint to it. Took mine 3.75 qts to fill also.

    Good job with the video!

    Just make sure you at least crack it loose before removing it... I heard these CVTs build up pressure, and if you don't take the fill plug out first, you won't be able to get it out. That darn bar was in the way! Lol.

    Another note: In my opinion, I'm glad it drains to the side facing the passenger, only because the side to side leveling is easier than front to back. In my opinion! :)

    Was it easy to remove the cover under the engine? Any screws or is it all just pins?

    Very nice! Thank you!

    I believe there are 11 clips that holds the plastic cover piece.
