Just frikin wow!

Come on now.... there's plenty of great information on cars here on the forum.
It is salted and peppered with misinformation and disinformation so you do have to separate it out for yourself.

I'm a proponent of just dropping all of the transmission fluid and changing it and the filter. If done at regular invoices, you're getting 80% of all of the fluid in one shot and it should be fine. Most wear metals should be stuck in the filter or pan, not in the torque converter and there isn't unburnt gasoline and etc from combustion gasses like the engine.

I know you added an emoji so you're joking.

However, Para and Arc have called on us multiple times to stay within our lane and not post in topics of a technical, specialized nature that we're not an expert in.

In those threads its a great place to read, read, read some more, and maybe ask questions since we inevitably have experts in every subject. Arguing with the expert will likely eventually end in them skipping those threads. Posting half-assed approaches, blindly repeating internet "facts", approaches that are dangerous (e.g. not up to National Electric Code), etc. can cost members money and possibly get them hurt if they don't properly separate the "disinformation."

You're an attorney, some of the "advice" in a divorce thread obviously makes the Sigforum Bar Association's skin crawl.

Those who say transmission fluid does not go bad do not formulate transmission fluids. Those who do have data of its degradation.

I haven't met a single one, now that I think about it.

Transmission shops love to sell transmission flushes. They love to sell transmissions, too. Funny, that.

Personal attacks are not cool. Try facts.

The dirty little secret the auto industry doesn't tell you is pretty much all the driving you do constitutes severe driving conditions. Subaru originally spec'd filled for life for their CVT transmission. Now they say service every 100k miles. So much for lifetime fluid life.

Yep.
I don't have to be a scientist to know transmission fluid does go bad and needs to periodically be changed. The question is "when" not "if".

Can Changing your Transmission Fluid Cause Damage?

As a former transmission tech I have to agree. We are just like any other technical industry I suppose. People who do not understand plumbing or other trade work often think they are being ripped off due to their not having the level of training or experience needed to fix the problem.

The "3x3" is perfectly OK - at least it gets most of the old fluid out - and is easiest for the DIY-er. As for whether you should or should not "flush," first off, the notion that transmission fluid never degrades is ludicrous and ignorant. No, it isn't subjected to combustion byproducts like engine oil, but it is subjected to plenty of heat. The 150-180-degree operating temperature is an average, after running back through the cooler. But before that, it was squeezed through tiny orifices or passages under high pressure. Of course it is going to degrade over time, miles and load.

I dislike the term "flush," preferring to call it a fluid exchange. Most fluid exchange machines use the transmission's own line pressure to circulate the fluid. If the transmission has a filter, internal or external, there is no reason for it to be "either-or." Drop the pan and change the filter (if applicable) and do the exchange to get the rest of it out of the torque converter and cooler.

More comments when I have more time.

This does have a removable pan and a filter. The pan is a pain to separate from the dipstick tube, the filter is more of a very fine mesh screen.

No dipstick tube.

I think for those year Toyota truck transmissions, they're "lifetime" fluid and shouldn't be changed, according to the people who designed and engineered the transmission. That's the official answer for my 2005 Tacoma. But what do they know?

Lifetime fluid...……..ummmmm, NO!! I have built many automatic transmissions. Lifetime fluid is a myth. I change all of my cars TF every 25-30,000 miles.

Tagged, Ive got to do mine soon!!!
