Prius C Tranmission/Transaxle/HSD Oil Change

I just changed my ATF in my C. I drained exactly 3 quarts out. When I filled it, it took 3 and 3/4 quarts before it flowed out the fill hole. Should I have only put 3 quarts in or did I do it right by filling until it flowed out the fill hole.
Thanks
Dan

 

Never mind, I see I did it right from the post above.

 

can we get some pictures? hopefully of the ATF oil product to order, pictures of where the hole and drains are, so non-mechanic savvy guys like me can do this??? <3

 

PriusC ATF fill plug on passengers side. Drain plug on drivers side at bottom. Per service/repair manual, torque on both is 37 ft lbs. There is no plate to remove to access. Tried to post pictures but I'm not "approved" for that yet. My original WS ATF drained at 26,262 miles is basically the color of thawed raw liver & attempting to look through a small amount of it spread thin in a zip loc bag looks the same & is non--transparent.
Color doesn't tell the whole story, but it's interesting.

 

No, you are wrong about this. The tranny will be more than fine at 100,000 before a flush.

Only the uninformed would think of flushing it at 30,000, or 60,000. It's a huge waste of $$.

 

Your definition of huge is slightly different than mine... $20 every 60k miles isn't huge to me.

 

If I darken my dentist's doorstep, now THAT'S a huge waste of money. Transaxle fluid change? Not so much. And, it isn't a flush, pretty much the lot comes out.

 

Really...that's like saying Defender "will be more than fine" to secure your Server, because using anything else is "a huge waste of $$". Good luck with that one too.

 

I don't need luck. All I need is facts, and input from real Toyota engineers. My tranny will be more than fine at 100,000 without a flush. As was the case for my two 2007 Yaris, my 4 Honda Civics, my CR-V, and several other cars.

 

Dan Lovell,

Fact be known, you could change the oil/filter 3 times and the front tires twice and your Prius will likely make it to 100,000 miles (barely) doing nothing else. I'll give you this, it's a guarantee your car will last until your next purchase.

You have 12 posts and it appears you just want to argue in most of them. Do your self a favor (or not...I could personally care less) and learn a little from the wealth of knowledge provided by seasoned owners on this forum, who just might know a little more about this car than your self. However if you just want to talk about how "smart" you are, http://priuschat.com/f/freds-house-of-politics.70/ is the place for you. Just message a Moderator and your in.

Sincerely,

The Mechanic.

 

I agree with that.
But in this case, I mostly agree with what he said too.

I get a little nervous letting things go for 100K miles before being serviced, that includes plugs, coolant and tranny oil. I get nervous around 60K miles and do the plugs and drain and refill the other serviceable fluids.....including the brakes if that hasn't been done. I NEVER "flush" anything that isn't showing symptoms of trouble. Never. (Except brakes, of course, which pretty much requires a "flush" to get the fluid changed.)

Some people get nervous a little sooner than I do............but asserting that those things "need" to be done aroung 30K miles is just OCD and totally unnecessary........except maybe for making you feel better.

Every time you mess with something that doesn't need it there is a chance of mucking something up in the process.

 

Do a search, the analysis has already been done for WS in Prius transmissions. The consensus here is first at 30,000 miles then every 60,000 there after, though I consider this minimum.

But what do I know...being just some dumb lowly mechanic that maintains almost 700 $50,000,000 aircraft for a living.

PS - For those that "don't know", the Prius transmission is not flushed, it's drain and fill like a gear box.

 

The consensus "here" would seem to conflict with the consensus among the Toyota engineers.
While I don't totally dismiss either, guess which I put the most stock in ????

And there you go again, trying to tell us that the Prius is an airplane.

 

You are good for a laugh. Have a nice day.

 

It is obvious you are a Toyota parrot. Please allow us that have different opinions discuss them without your shoving yours down our threads. Your experiences are only one part of the story.

Please go back and read this entire site for another month, then come back and join in the ...conversation... without being so smug and overbearing. That is a combination that, as a Prius driver, you should not want to emulate.

 

Mr. Incredible, why are you so into ordering others around? Why so controlling?

I may be new to Prius but I'm not new to cars, transmissions, motors. So there is no reason for me to keep my mouth shut just because I have 12 posts.

I've owned 4 Toyotas and have never changed the AT fluid before 100,000 miles per the manual, and none of these cars experienced AT failure after 200,000 miles.

Those with objective scientific minds would understand. It seems you're not one of those.

 

I guess for some it might be a peace of mind issue as well. Yes, I can see where it would be ideal to change it sooner, to maintain the transmission. If others are okay with not changing it or waiting till after 100K miles, okay. Just like with anything else. I am going to get mine changed at my next service at 35K. I just think prevention is better than a cure. I will just feel more relaxed that it has been drained and filled. If you feel it is not needed, I respect your decision. At the end of the day, it is MY CAR, MY MONEY, and TIME, and I will spend it however I wish maintaining my car.
