Auto transmission mini fill/drain every 3k...

Yeah. I’ll say it again.
OP can do what ever he wants.
And I don’t abide by industry standards, especially when I have no idea what industry standard to go by? Aisin maybe?

 

If you could quote where I said this is the industry standard for light vehicles I would appreciate it.

AGAIN, in INDUSTRY partial drop and replace is normal, and those practice can ALSO BE APPLIED HERE.

So drop and fill the WHOLE THING every 60,000 miles, or drop and fill a PORTION regularly. The end effect is the same.

I can never tell if folks really can't understand these topics or are purposely being obtuse.

 

If those are my choices, I’m going with drop and fill every 60k, before I drain and fill every 3k. If I have to drain and fill every 3k, then I need a different truck.

Anyone else can do how they please.
Their time, their money.

The best advice I can give is go by what Toyota and Aisin set forth in the manual.
I don’t know exactly what the manual says, I don’t go by the manual exactly.

 

My god, do you not understand it is the same thing? Replace a little bit over time or replace the whole thing in one shot.

Then you say make sure to follow the manual, but don't follow the manual.

Why am I not surprised around here

 

No. I said the best advice is to go by the manual. I also said I don’t go by the manual. What I do, and what you should do, are two different things.

What I think you don’t understand is, I never told OP what to do. I stated what I wouldn’t do. I also think you don’t understand that I don’t care about industry standards.

To make this more understandable, I will say the following

1. I don’t care about industry standards.

2. I am not changing transmission fluid at 3,000 miles. Not a little bit, not a whole lot. None. I’m not changing anything.

3. If I have change fluid at 3,000, than I don’t want it.

4. I will agree ( yeah, I said it)
Exchanging a little fluid every 3k is marginally better than changing all the fluid at 60k.

5. If the transmission can’t run on “a little worse” fluid, it’s not for me. We’re back to #3.

6. Lastly, I’m not concerned at all about the state of the fluid in 3k increments. I’ll go based off how I use the truck/transmission.

 

Holy shit.

Nobody told you what YOU had to do.

Nobody said this is what anyone SHOULD do.

The OP was asking if it's OK if HE does this. And you decided to argue the shit out of it.

 

Similar experience. I started driving in 1973. I've never changed the ATF on any vehicle I've ever owned. The only transmission issues I've had were electrical. I have over 1/2 million combined miles sitting on the driveway with the factory transmission fluid in all of them. Almost 1/2 of that on my 07 Tacoma. They all drive just like the day they were bought.

If you do a service every 30,000 miles you'll actually end up spending more on servicing the transmission than it would cost to have it rebuilt. And you'll still have to pay to have it rebuilt at about the same point.

 

You’re getting awfully upset about unnecessary maintenance.

In which industry?

 

Yeah. Pretty much.
I never said what anyone should do.
No one said what I should do.

I said what I wouldn’t do.
I also said more than once, op can do what ever he wants.
Somewhere in there I said, “it can’t hurt it”.

I ain’t arguing. I am repeatedly saying the same thing over and over.
I’ll quit saying it eventually. But I am not quite burnt out just yet.
It’s still a bit comical to me at the moment.

 

Is this an episode of dumb and dumber??

 

Yes to everything you said. Sounds crazy check, quick easy simple check, overkill check, but hey you do you . Want I can say is 5 Toyotas in myself , 60k fluid changes all ran fine still with 400k miles on them.

 

Thank you!

As stated in my OP I'm not talking about a drain in fill, in fact I should have titled this thread FILL/CHECK as the drain plug would never be removed. I'm talking about slightly over filling the tranny by half to 1 qt and then going through the temp check procedure draining the excess fluid from the check port.

Also, some of you guys need to chill. I literally said in the first sentence I acknowledge how crazy this may sound. The entire point of this website existing is to ask questions, discuss topics, and share ideas and information. I can guarantee some of you do things and treat your truck how I never and vice versa. Nobody's wrong, nobody's right. Stop caring so much.

 

Lots of Toyota transmission information from that Toyota guy on YouTube. https://youtu.be/jJr30r6RRgw

 

That Toyota guy is fantastic...

 

You’ve been a member here long enough to know that fluid changes of any kind can be a controversial topic with differing opinions. Nobody needs to ‘chill’ …

 

I think 50% of the time, it’s on purpose. The other 50% is just stupidity.

 

I'll play along.

OP, do as you please, whatever might give you the tinglies and satisfaction. I do annual drain and fills, so usually it's about 10K-13K miles in between. Overkill? Perhaps. My truck also has 325K on it and I plan to keep it for as long as I can. So again, do as you please. I will say, 3K might be overkill, but if you're changing your engine oil at the same time and enjoy knocking out both at the same time, then I can understand where you're coming from, so I don't fault you there. Take it for what it's worth.

 

I think this really depends on where in the fluid the majority of particulate matter accumulates. That's to say if it "floats" and you are draining off the top inch, then you're doing a good thing, or conversely, if it sinks, and you are draining out the bottom inch, then that's good. If it's equally suspended throughout, you're essentially following the principle of "dilution is the solution to pollution," which isn't a bad thing necessarily. If any of the above isn't true, it may be all for naught. Especially considering you'd eventually want to replace the filter, right? Where, by design, the majority of the particulate matter definitely does accumulate.

PS...starting an open topic, then telling people who bring data or experiences into that conversation by participating, to chill...is a bit weird, to say the least.

 

Careful with those drain plug threads. That little plug really isn't designed to be removed and retightened that much. Heck there's only like 5 threads in the pan side. But whatever floats your boat

I've done one spill and fill in 160,000 miles

These trucks aren't that brittle, I don't see what exactly is being gained by doing it so frequently

 

All it is doing is instead of every 60,000 miles doing a complete change of fluid you are just doing a small portion of fluid every 3,000 miles (or every oil change). Its the same thing but instead of changing all fluid at once you change all the fluid a little bit at a time.

Just two methods to try and achieve the same goal, OP just figures that since he is already under there doing maintenance just add a little bit of time and do some to the transmission as well instead of doing it as one big service at a different time.
