Sealed Trasmission fluid change

But it was a good point, because it's the same breather Toyota uses on the trans etc. Also I never said it never needs to be changed. I'm just telling you that's their reasoning

 

The rear is one way but beside the point. There isnt enough air in the aircavity/diff to generate enough pressure in or out to have any discernable bearing on the seals.

I've wheeledd my truck more than most and still has the stock breather. Two way breathers are always extended, which is why you see extensions on the transmissions and transfer case.

 

From the "lifetime fluids" entry on Wikipedia.

 

Ever felt your diff? It’s definitely gets super hot.

No breather on any Toyota is truly “one-way” as that would not make any sense. Anything system that heats up will cool down, and anything that expands will contract, and vice versa.

I have the diff breather off my rear Diff from when I relocated it. It is now terminated in a high-mounted fuel filter, so I’ve played around with the diff breather.

It is a “one way” only in that it breathes freely on expansion, but is limited on contraction, in the speed it will allow air to suck back into the diff. Your can blow out the diff breather easily, but it takes some force to suck back in, still a regulated flow passes back through the breather. This is why people who don’t extend their diff breathers rarely have actual problems as it is design to be momentarily submerged and not suck in water. It won’t work for a long time when you are stuck in a puddle.

Anyways…..all breathers on Toyotas permit two-way transfer of gasses, but the rate at which they permit that may vary.

 

Nor Toyota or Aisin make the claim that it is maintenance free. Toyota applies "special conditions" as the majority of the driving conditions.
The below are full fluid replacement intervals; not drain and fills.

As far as mileage intervals; anywhere from 25,000 to never. Your truck, your call.

 

it IS a cooler, AND a heat exchanger. It is highly effective at removing heat from the transmission.

I see all these folks pinning their thermostat and adding all these accessory coolers and removing the factory one and it shows they have zero understanding of how the system works, all they think is “colder better”

Transmission fluid has a range where it works best. As long as it doesn’t OVERheat it’s happy, and it’s happy even if that temp is at the higher side of the scale.

 

Hmmm, real data? A guy who owns a local shop is now the authority?Lol, And you are the arbiter of what is correct? Wow! You have a fairly high opinion of yourself and seems you also have a temper problem that compels you to come on here an assert yourself. Why this causes you so much consternation seems as if this is a life-long situation of people ignoring you. And so here you go again on your hampster wheel. I can only imagine the wheelbarrow of problems you must carry around with you.

Possibly you meant to be over in this forum? https://www.mentalhealthforum.net/forum/threads/awful-troubled-week.367431/

 

Well now. We seem to be making progress. We have moved off of “never” to “too often”. Thata boy.

Now you have me thinking. Why would Toyota design-in a drain plug, a check plug and a fill plug along with many pan bolts if it is truly intended to never be touched / serviced? You have said to ignore all that suggest drop another transmission in when you have a problem, lol.

One more thing, it seems you correlate time with knowledge. Just because you’ve done something for thirty years doesn’t make you the go-to knowledge source. Your posts are proof I am correct.

 

Vessels are female, brah! And this girl's a beauty.

 

I have a shit-ton of respect for Toyota's engineering but their bottom-line money hungry financial "people" can kiss my ass along with the bean counters from every other manufacturer.

Use your head. Yes, lubricants are better today then ever and that will continue but shit wears out. The world today is all about build crap and replace it often. It's BS. Nother more than a "SELF LICKING ICE CREAM CONE".

 

What's the big deal? Once in awhile drain off a little....put a little fresh back in and make sure the level is correct.





And to make it even easier.....make a plug and play OBDII jumper and replace that pesky 5mm allen overflow bolt with a drain bolt.

 

The fact that you cannot understand the difference between actual real data, and some guy on the internet spewing the literal definition of hearsay that you happen to agree with is the damn problem. You have proven you ARE the type that just believes the “youtuber” when whatever they say agrees with you, you just don’t use YouTube itself.


The folks that only listen to what they want to hear is too damn high

 

FWIW, another personnel experience.
2007 Toyota Corolla CE. Yes, the Cheap Edition. This was my commuter car, it took the place of commuting in an '04 GMC 2500 HD 6.0L. My commute was nearly 2 hours one way on interstate. The car was driven through its 100K warranty in 14 months. I had a yearly transmission fluid change. When it was passed to my daughter as a college ride, it had nearly 200K on the odo. She drove it for several years and then sold it at 240K to a friend of hers. Last we knew, it was still rolling. Pretty beat up and rusted with mismatched body panels with numerous parking lot dings.

That Corolla was ridden hard and put away wet. Never had an engine or mechanical failure. I was fastidious about oil changes and maintenance. Shoot at one point, the oil changes were monthly. I had the process down to <15 minutes. Quick lube shops had nothing on me for speed.

My professional experience has led me to preventative maintenance. A breakdown never happens at a convenient time or location. Personally, I think it is very ignorant to run something until breakdown and skip maintenance.

Take it down a notch. This is a friendly, drama-free forum for the most part and the vast majority of us prefer it that way. It’s very simple to disagree with someone without personal attacks.

 

Yea......but its the internet.....

many people have keyboard cahonies.

Never listen to people shouting. Listen to the people who calmly talk. One gets attention by noise, the other gets attention by knowledge.

 

True...but this is the 3rd generation forum. It comes pre-drama'd from the factory.



That said....there will be opinions from both sides. There are those who believe fluid change is necessary and those who do not. Those who do not tend to fall in 2 categories....those who truly feel it's not needed and those who say it's not needed because transmissions seem like a scary enigma to service and it's easier just to say, "don't need it".

Personally, I'm a clean fluid kinda guy. I've done a few DAFs on the tranny juice because it makes me feel better. Do I have any science data behind that to show my transmission will last longer? No, not really. But who cares? It's something I don't mind doing.

And as long as we're on the subject of opinions and speculation....I know a gentleman who recently retired from 48 years as an ASA Master Toyota Tech. He does fluid changes. Take that for whatever it's worth.

 

Hmm, I guess I misinterpreted the knucklehead, dipshit, and half-a-brain insults levied by the dipshit as something not consistent with drama-free. And my reply is the offensive one?

 

Regarding maintenance and intervals of anything, there are myths, legends and truth.
Regarding posts on the internet, be it a forum or social media, there is as much bad information as good information. In reality on pretty much any subject, the actual truth is somewhere in the middle.
For example, @mquibble recently posted a thread on his method of oil changes. I think some of us agree that is pretty much extreme maintenance! BTW, I have zero problems with quibble the person. He is probably a great guy. I do have issues with his thread because I think some noob reading that thread might think that his way is what is needed to get the most life and he would be wrong.
I don't want to argue because hey, if he wants to spend all his time changing his oil then more power to him. I wrote a contrarian post so that noob might read it and think "Hmmm, one guy says X and the other guy says Y, I might need to read my manual."
I did the same here. My tone? Maybe wrong. My point? Don't think changing trans fluid every 30K will help.
I only listed my experience because somebody asked.

I do think my posts might hit too close to home for some people and, they take offense, thinking I am talking about them.
I assure you I have a very normal life lol.

In regards to @Sharpish post, while it might seem to you that I am a "know it all" nothing to be further from the truth.
You can go back through my posts for example and never find one on electronics. I only know basic electronics and usually don't know enough to comment.
I also don't comment much on interior discussion.

Also, I am not always right. I don't know anyone who is always right.
I am getting older. I realize times have changed. I am bewildered by the fact that actions that were totally accepted by society ten years ago are now scorned by some. Think comedians and jokes and statues.
I have two adult children aged 26 and 29. They are trying to teach me how to act correctly in 2021. I am trying.

Lastly, I quoted all you not to reply to your posts, but to tag you to read this.
Thanks and remember, I personally have zero problems with the people behind the posts, only sometimes the post itself.

 

Not having a dipstick also means stupid for a lotta' people, too.
