Back in June, I posted a question in regards to a 2009 prius with 67000 miles on when I should have the Transaxle serviced. I was buying the car used from the dealer. I received a lot of replies as well as part numbers. But when I went to the dealer I ended up purchasing a 2010 with 60000 miles. I'm now approaching 70000 miles and was going to have the transaxle serviced along with the oil change. Are the part numbers the same as a 2009 prius? ATFWS #00289-ATWS, crush washers - #90430-18008? Thanks, Jim
I believe the crush washers are 90430-A0003 now. I have a bag of the crush washers, pm me if you want 2 of them for $2.50, the dealer price here was $2.75 per washer, so I sourced some washers in bulk. SCH-I535
If you're buying at a dealership parts department, it's sufficient to just: 1. Tell them your car model/year 2. Ask for 4 quarts (or liters) of ATF-WS and washers for the transaxle drain/fill bolts. Also, if you're discussing it with them, say you're doing a transaxle fluid replacement, not a "service" or "maintenance". Just clearer.
Thank you for the replies. I will definitely use the word "replacement", because when I brought it in for its first oil change last month, I had asked about the cost to service the transaxle fluid and the response from the clerk was it would not need to be serviced until I had an issue with the vehicle. Thanks again, Jim
I recently changed my transaxle fluid on my 2010 Prius at 50k miles. I drained 3 1/4 quarts with the car level. It took 4 1/4 quarts when I refilled. No leaks were detected. I think it was under filled at the factory.
I can't see any reason to measure what comes out, or how that measurement would have any bearing on the refill. If you just completely drain (and it will mostly drain, it's different than a traditional automatic), ensure the car's level (just the best you can), and then pour in fresh 'till it starts coming back out, and let it sit with the fill bolt out 'till the flow out subsides, then you've got the level right. I'm having a hard time seeing how you could get 4 1/4 quarts in. In my experience it took about 3.5 liters, maybe 3.8 quarts? Best guess: you were pouring fast, and a fair bit spilled back out? The car was still level when you did the fill??
I had poured the drained tranny fluid into an empty 5 quart oil container. The container shows the volume on the side where the container plastic is clear. I did not purposely measure the old fluid. I just put it in an old oil container and looked at the volume I removed. I pumped the fluid in from the bottom of the car. I did not force the fluid in. When the fluid started to drip out from over filling, I reinstalled the plug. Toyota is notorious for under filling their automatic transmissions. I was short a quart on my 2013 Tacoma when the level was checked.
FWIW, the "capacity" in the service/owner's manual is what SHOULD be in the vehicle. Where lubricant is concerned, fluid levels can be considerably lower with no damage to the component. The capacity factors in a massive safety margin. So, I wouldn't be surprised if auto makers short customers on how much they put in at the factory. One US Quart less than max capacity does no harm but save them millions in the long run, I'm sure.
Just an update. Had the car serviced at the dealer yesterday and requested a transaxle fluid "replacement". I had a much easier time requesting the service by using the word replacement verses serviced. My only concern was that I was billed for 3 units of BG Gear oil (part # BG974616) and not for 4 qts of ATF-WS. I asked the service rep and his reply was that Toyota services the transaxle with a kit and that when the mechanic refills the unit, the computer will let him know when the unit is topped off. Also for anybody who is think of having this done, I was billed for 3 units at $12.47 each, and the labor rate was $59.94. Thanks again for all the replies.
i remember my car took more to fill than i got out, its been so long i can remember how much the diff. I SUSPECT that they fill at a higher temp than what i drained. temp will make a big diff.. not sure wht the required temp to change would be.
Is anyone getting oil analysis done on these Gen III transaxle fluid changes like we were doing on the Gen II cars? I'm just wondering. I just bought a new 2014 v and I'm wondering what my first fluid change interval should really be. I'm doing 60K intervals on the old 2007 car.
Sounds to me like they used the WRONG fluid, AND under filled. That bit about the computer telling them when it's "topped off" is pure BS: you just fill 'till it starts coming back out. And what the heck is a "unit". They should have drained, then added Toyota ATF-WS Transaxle Fluid. It takes a bit over 3,5 quarts or liters. I'm not sure what you should do now.... Contact Toyota? Demand a flush and ATF-WS fill. Even the Owners Manual stipulates ATF-WS, warns to not use anything else.
