    Great idea! I don't know if the Gen 5 is that much different than the Gen 4 but, a few months ago, I did the 5-year service on my wife's 2017 and both coolant and traction (inverter) coolant came out to 1.5 gallons and the transmission WS was 3 3/4 qts.

    A/C is absolutely fine. It's driven by an electric motor, not the engine, so there's no additional significant load.

    Just give them the part number. That should be all they need.
    08886-02605

    But you're not going to need it for 6+ years, so there's really no rush. ;)




    BTW, I put the interval at 6y/60k, but you could easily push that out even to 9y. I did 6y/60k just to line it up with the spark plugs at 120k. Though I may alter it to 7y, 7.5y, or 8y, so there's a significant service more frequently.

    There's two schools of thought for major service intervals.
    1. Clump them together as much as possible. This is more convenient and cheaper for the owner.
    2. Spread them out as much as possible. If you have a good mechanic(or you do it yourself), this gets them underneath your vehicle for a longer period of time more often(as opposed to just an oil change). In turn, this increases the chances of them spotting a problem earlier in the failure chain. Knowing about something earlier can mean either a less costly repair*, or you can better plan your finances if it's going to be something big.


    *For example: Cracked CV boot. If you catch it early, you can just have the boot replaced. If it goes for awhile, the boot and seals will have to be replaced; more expensive. But if it goes for a very extended period while badly cracked, the lubrication leaks out of the boot and gets contaminated with sand and dirt particles. This can get into the joints and, with the the loss of the lubrication, can ruin the whole CV axle. A very, very expensive repair in the worst-case.

    Oil filters come with a gasket included, but it's good to know the part number just in case(you scared me for a minute, so I had to run and check the spare filter I keep on hand - lol). Thanks.

    Maybe just through your dealership parts department? They are separate parts, separate numbers. I've always seen two charges, one for filter, one for washer. Most recently the washer was $1.84 CDN.

    It really shouldn't be necessary to have parts numbers at the ready when at the parts department counter. If you tell them what your car is, they should be able to sort it out; that's their job. And if you bought there, or have at least been there a few times, they should have your vehicle stats registered, under your phone number.

    FWIW, that's the same oil pan drain bolt washer number as my '10, pretty ubiquitous I think.

    Yep I'm very glad Toyota tries to keep-it-simple...I maintain 6 Toyotas for our family (from an 08 to a 21) and the 14mm socket drains all the oil and there's two different size wrenches for the cannister oil filters and one for all spin-on cartridge oil filters....makes the job easy.

    I don't think I've ever bought the Toyota oil drain crush washer...just got a bag full on Amazon years ago and still going through them.

    You've only dealt with spin on filters I take it. With cartridge ones, you have to replace the O-ring that is on the housing cap when doing the change. Every cartridge filter I bought came with the O-ring, but it can be lost or get damaged during install.

    I had the cartridge style till a few years back, till I converted it to spin-on. The O-ring on cartridge style does come with the filter. But not the drain bolt washer in my experience.

    For TE fluid, I got the P/N 08886-81986 from a dealership parts department. On the Toyota parts website, the page seems incomplete - misspelled "transaxel," no images, and no notes on how big the container is. I hope it's not a single quart being sold at $90 MSRP.

    I placed an online order for 1* x 08886-81986 with my favorite dealership parts department about a month ago. Today they confirmed they still don't see an ETA on their report. Does anyone think I should try a different dealer and/or have suggestions on where else to go?

    *I was hoping it'd show up quickly enough that I could look at the container and order more if needed.

    I'm getting a bit frantic, as I average about 8K a month for work and will probably hit the 50K at which I hoped to do the change in a couple weeks. I may end up pushing to 60K whether I like it or not. When I first got the car, a friend who's the head tech at a (non-Toyota) shop and obsessively overmaintains his cars advised me to do the first change at 25K just for the heck of it. I quite simply was not on top of things when I hit 25K.

    @Hammersmith, where did you get 08886-02605? It doesn't return anything on the Toyota parts site, but my experience with the P/N I found doesn't inspire faith in the site.

    I did a little digging and it looks like that old part number has been discontinued. Try 08886-81986. It comes in a 4 liter can, so you'll just need the one. You'll want it to say e-Transaxle, Type TE, or EV Transaxle Fluid on the can. It's the same stuff the bZ4X & Lexus RX use in their transaxles.

    Don't worry at all that you haven't done it yet. Honestly, you can go all the way to 90k miles without any ill effects, but I understand the desire to go above and beyond. Your friend might be thinking of standard CVT transmissions with the 25k advice. Standard CVTs need to be babied to get their full service lives(especially those from Nissan), but the eCVTs in Toyota hybrids are completely mechanically different on the inside. They don't operate using the same principles at all.

    Just judging from colour of drained transaxle fluid on our Gen 3, if you were going to do one drain-and-fill, I’d do it early, around one year or 10k miles.

    I just picked up my TE fluid. 08886-81986, one 4L bottle, true to @Hammersmith's word. I'll do the change when I find the time and motivation after doing my taxes, changing the oil on my friend's Gen 2, and shipping my Gen 3 Project Lithium pack out for the V2.5 upgrade.

    The torque spec for transmission drain and fill plugs is 37 ft-lbs.
