Default Your CT200h transaxle fluid is toast if it's original...

Someone linked this from Prius chat..(same transaxle as ours) https://priuschat.com/threads/2010-t....128673/page-2

Their 70k Blackstone Labs report on the stock transaxle Toyota WS fluid came back horrible! (again, NOT mine) someone elses. lol. Go out and change yours. it's easy. and cheap.

See my post here: https://www.clublexus.com/forums/ct-...l#post10442336

You should get yours tested to confirm it's toast.

In order to get it tested you have to drain it. If you are going to drain it, are you going to go through all that trouble of putting the car on jackstands, removing all the panels, and draining the fluid and not pour in new fluid? The fluid is cheap...

Also what would you replace the fluid you pulled for the sample with?

You came on here and preached to us that our fluid is toast. I have a 2017 with only 23k. Not even close. My point is, you have one sample data point and come telling us our fluid is toast. It's good reminder to check, for those that want to get it tested. Do you have near 70k miles? if so, maybe you can get yours tested and confirm what you posted. That's all I was saying.

Also why would I test my fluid if I just replaced it... it's new

Seems to me some arguing this can't afford 4 quarts of oil so are defending not maintaining their cars. If the fluid was free, I wonder if they'd still hoot and hollar

My point is (if you read) one would have to drain the fluid in order to test it and send it to the lab. My question to you is, would you put back in the old fluid or simply replace it? Testing is moot especially when testing it is half the cost of new fluid. Replace it and stop being cheap

Some poor soul out there will see your thread and freak out. They may or may not post.

I guess good on you for making us aware of a possible issue.

My car is just fine and low mileage. I bought my car brand new and know the history. I'll cross that bridge when I get there.

If your car is new then obviously this info is not for you. Most of us have high mileage with original fluid. If you are above 40k, I'd replace it.

There's only 4 quarts inside the transaxle so it doesn't take much heat, time, or miles to foul it.

It's not like your typical transmission that houses 10 quarts AND a filter.

We have 4 quarts and no filter.

Also I'll add even if you do have low miles, I'd still replace it if you intend on keeping the car long. The factory fill will have metal shavings from when the transaxle was broken in. Those metal shavings are swimming around being ground into all your gears until you do your very first change.

For $40, up to you.

Let's keep this thread civilized!

I actually change my trans fluid every 60K miles...as E46CT states it's for good measure and simple preventative maintenance. I also change my oil and oil filter every 5K miles...
