The swearing and getting pissed off tops off the vid. Thank you for making this for us!!!

Finally a video on the 2019-22 Prius love it thanks bro !

Toyota tightens the shit on Prius! Your fluid looked pretty good. I've seen older gens & its brown. I put anti-seize on my clips when I took mine to get undercoated, I'll see how that works. 👍

God bless you and your family 🙏🙏🙏

I note that you bought a quart of Valvoline CVT Fluid for your Ascent. The following will help establish that Amsoil "100 Synthetic" Signature Series Fuel Efficient ATF Fluid is vastly superior to the Toyota "Full Synthetic" WS ATF Fluid (made by Exxon Mobil). You can compare the Safety Data Sheets between Amsoil and Toyota fluids and you will find the Toyota WS ATF (and true of the vast number of full synthetics) is mostly composed of hydrocracked-petroleum oil, a Class III Synthetic (extra-refined petroleum to mostly eliminate impurities, but it doesn’t get totally get rid of then entirely). Amsoil Signature Series doesn’t contain a drop of petroleum oil, but a pure chemical mixture of Class IV Synthetic, known as polyalphaolefins (PAOs) and Class V Synthetic (such as Esters), plus top-shelf additives. Toyota lists the Flash Point of their WS ATF Fluid as 347° F (175° C), whereas Amsoil's Flash Point is listed as 435.2 F (224° C), so Amsoil holds up to the heat far better than the Toyota WS ATF. Another convenience factor of the Amsoil "100 Synthetic" Signature Series Fuel Efficient ATF Fluid is thay it is available in collapsible bags making installation a snap (without the need for a pump that only provides a slow fill operation)! The difference between a Full Synthetic and a 100% Synthetic? Rafe Britton, a former Lubrication Engineer at Mobil and the creator of a number of highly educational KZfaq Videos under the heading of “Lubrication Explained,” states in order for an oil company to call its oil product 100% synthetic, it must be composed of either a Class IV Synthetic (PAOs) AND/OR Class V Synthetic (such as Esters), while being completely devoid of refined petroleum. Since 2004 I have exclusively been using 100% synthetic oils, fluids and gear oils made by Amsoil. In my 2013 Subaru Tribeca I use 5W-30, which has a Pour Point (PP) of -58 F and my Toyota Camry Hybrid uses 0W-20, which has a PP of -63 F. I have never experienced any problems starting my vehicles any longer using 100% synthetic products . I also changed the 100% Synthetic ATF in both my vehicles at about 40,000 miles (the Multi-Vehicle ATF in my Tribeca’s transmission and power steering reservoir has a PP of -63 F, while the Fuel-Efficient ATF in my Camry Hybrid (with a similar eCVT as your Prius) has a PP of -85 F. The moment I drove the Camry after the installation of the Amsoil ATF (without any other services being performed on my vehicle), I not only detected the vehicle was running a bit smoother, but also experienced increased power upon acceleration. More importantly, my EV light was coming on more often and staying lit longer (which of course signifies my car is running electrically from the battery, while the gas engine isn't operating) Also around 40,000 miles, I changed the gear oil in both differentials in the Tribeca with Amsoil 100% synthetic 75W-90 Gear Oil (that has a PP of -45 F), which ran much better at any time than the original full synthetic gear oil from the Subaru Factory. I also changed the Coolant and brake fluid in both vehicles to Amsoil. Another benefit of using Amsoil (other than the great performance), my vehicles are covered by the widest warranty in the business regardless of the age and mileage of your vehicle, even if this was the first time trying Amsoil (as long as your vehicle was in good mechanical condition at the time you first started using Amsoil). For those of you seeking a less expensive ATF, you might consider Amsoil "100 Synthetic" OE Fuel Efficient ATF Fluid, which isn't available in the easy-to-pour pack (only the conventional quart or gallon plastic containers). The OE ATF has the same Flash Point 435.2 °F (224° C) as the Signature Series, but a higher Pour Point at -54°F (-48° C) compared to the Signature Series (at -85 F). The lower a Pour Point, the better for running your vehicle in cold temperatures. The OE must be changed according to the manufacturer's specifications for your specific vehicle, however, the Signature Series will go double the distance (than the OE) under severe-driving conditions. For those of you that have a vehicle that doesn't accept a Fuel-Effecient ATF, you may consider the Amsoil 100% Synthetic Multi-Vehicle ATF (in both the Signature Series and the OE). They also carry 100% Synthetic in both their CVT fluid and Dual-Clutch Transmisson Fluid. I had tried a variety of full synthetics over the years. I began to utilize Mobil 1 for several years thereafter, until I found Amsoil being sold by an auto parts store that is no longer in operation. After I personally emptied the Mobil 1 and I put it in the Amsoil in my car about 20 years ago, I was blown away with the increased performance, better fuel efficiency and the overall quietness of my engine. For full disclosure (as probably guessed right now), I am an Independent Amsoil Dealer (all dealers of Amsoil are independent contractors, as opposed to employees of Amsoil). . If consumers wish to buy the Amsoil products as a Preferred Customer (PC), they will get the oil at a 25% discount, plus free shipping when they spend $100 (plus receiving a $5 coupon for every $100 you spend). It only costs $10 for a 6 month PC membership (or $20 a year) and there is no requirement to purchase (as there is with so many companies offering a membership for a preferred customer program, where there is an automatic shipment involved). If you are tempted to try Amsoil, I invite you to visit the official website of Amsoil and apply to become my Preferred Customer, by kindly utilizing my name (James Norris) in the box underneath the question that asks “Did someone refer you to Amsoil? If so, please tell us.” Then in the next box they ask “Have a Referral Number? Enter it below:” I kindly ask that you include my Referral Number of 1420935 in that box. If you can write down my name and referral number, before you eventually decide to exit this webpage, it will be appreciated (so that it will be at your fingertips when you get on the Amsoil website). You can also write me an email addressed to AutomotiveBuff at my gmail address (in case you have any questions).

You could run long hose & funnel from top to down and the gravity will do the work for you. Just make sure the hose is not going any where.

I have a question why you didn’t change the filter for the transmission

Do you have a part number for the hand pump you mentioned at time 8:39? It looks like it screws on top of the transmission fluid bottle. Thanks in advance.

@meegs3042 great video bro! But what about the filter? It doesn't have?

did you use new gaskets ?

I think fill plug is 37ftlbs, a big comical insemination syringe pump would be quicker than your hand sanitizer pump! Great video!

Hello, I have doubts regarding the interval for the oil change in the CVT gearbox of a hybrid TOYOTA PRIUS+1.8 VVT-I HSD ECO. How often do you think it's advisable to change it? Best regards

My 2016 Prius has only 58,700 miles. The car was mostly driven in Hawaiʻi so that’s why it has low mileage, but now I live in the mainland. I want to change my transmission oil but I’m currently broke. I was thinking of using Royal Purple’s Max ATF oil which also works with the Prius. Does anyone know if the Royal Purple is superior than the Toyota brand? I’ve used Royal Purple motor oil in my Prius and there is a huge difference in performance, so I was wondering if their Max ATF oil would improve on transmission performance, not that I’m having transmission issues. What kind of performance improvement did I get with Royal Purple motor oil? I’ve noticed that I can cruise 80-90mph with the eco meter not in the red, and the engine sounds less strained. My battery also stays more charged than before, probably because the engine has less friction and can turn more energy into electricity. Also, accelerating to pass while cruising on the freeway is noticeably more responsive. That’s just what I’ve anecdotally noticed. It just feels peppier.

I could be wrong but It’s easier to fill the fluid through the dip stick tube.

Is there not a filter?

Nice air bubbles 😵

Once you put the 3 1/2 quarts in, you should start the vehicle to get the fluid warm because it expands when it heats up. Leave the dream plug open while the vehicle is warming up.

The last comments post was sent in error (I apologize for the oversight)!. I wrote a revised email as follows: I note that you bought 4 quarts of Toyota WS ATF to accomplish your fluid replacement in your Prius' eCVT.

My local Toyota dealer quoted $510 for this service so I did it at Valvoline for $180.
