Automatic transmission fluid and filter change

[HEMIMANN]

It's not really a theory, it is maintenance requirements long known for automatic transmissions. You can google about it anywhere.

When transmissions are neglected by not changing oil regularly, they build up oxidized oil deposits (varnish) and clutch and gear shavings not caught in the oil filter (or oil filter is in fully bypass mode). Flushing loosens deposits and plugs solenoid orifices. Then your transmission is junk and requires a total rebuild or new.

I'm not trying to be a **** here but googling anything these days has so much inaccurate information that cannot be trusted. I thought you were actually speaking from experience. Thanks for the reply.

The risk depends on the current fluid condition and how it's running. If the fluid isn't burnt or stinky and the transmission shifts fine, I would do a pan drop, filter replacement and refill - NOT A FLUSH!. If the fluid is burnt, then it's a bit riskier. It's not that fresh fluid in a neglected transmission causes damage, it's that the damage has already been done and fresh fluid can cause the issues to be more pronounced and add to more slipping. I'd start by having the shop check the fluid condition before making up your mind.

I am. Where does one get experience today? Unless you're in school or work, guess where? Yeah, you got to cross reference for reliable sources, but I know how to do that after decades of researching books, then on the net.

Meaning you performed the flushing and that was the result. 1st hand experience is what I'm referring to.

No - I am a degreed Mechanical Engineer that has worked in power train and lubricant industry for 32 years. I am educated in machine lubrication.

I am telling you - today, the internet is wear information is searched for. Multiple sources. People don't source hardcopy books and manuals anymore.

Had you led with that answer I might have believed you. But without speaking from your own experience which you have admitted you're not keep it moving. Thanks for the reply.

There's more information available by googling than ever before if you know how to find it. If one simply takes the lazy route looking at the first thing that pops up they can end up with the wrong information and makes knee jerk assumptions about things.
The risks of a transmission flush with high mileage/low maintenance are widely known, spend a little time researching just about any car forum about transmission service and you'll find the warnings.

First of all this conversation changed from changing the fluid and filter over 150k to flushing. I just asked the question earlier on why they thought changing fluid and filter after 150k caused more damage. No one cares about flushing.

I stick to my answer about Google. I agree with you guys unless it's coming from an academic site on the subject the reference "googling" is trash. Good day.

 

[RedSRT4Me]

typically any vehicles with 150k+ miles on them DO NOT change out the AT fluid... You could cause a series of issues when placing new oil in it, unless of course you have been keeping on top of your regular changes then it's ok.

Back to the original question from the guy who has not stated an engineering degree.

To this statement that changed to flushing.

From a mechanical engineer who referenced the general Google search as his site reference and not an academic site

Your showing how naive you are about using Google, which is a search engine finds the "academic" sites your referring to.

On the off topic, lose the attitude

I asked a question. I made valid points to my question. Don't change my words because you're an admin. I didn't use naive in any reference towards him.

Google it for yourselves. You'll see the conflicting information both for and against on other transmissions. My question was direct at who has first hand experience changing this 8hp70 transmission fluid with high miles and having adverse effects.

So far the answers are comical at best with general references to nothing specific.

Good day

That's a real cheap move you attempted there.

First off there was nothing cheap about my reply, I answered your statement. You were attempting to down play googling for information.
Second you need to slow down and reread what I stated, I didn't say you call him naive, I pointed out your lack of understanding Googling.
Think very carefully about how you reply going forward.

I have a 2015 1500 5.7L Hemi. Yes the tick has been fixed. Plugs were changed also. I have been told it's not needed to change the tranny fluid. If it's got a filter then it probably does. I've seen some videos on YouTube but it all seems different. Figured I'd ask yalls opinion. I have over 100k on it. I think it needs to be done. What am I looking at? What are the tips and tricks and info on doing this? Do I need a new pan with a replaceable filter? Does it have a replaceable filter already? What fluid do I use? Sorry for all the questions but these vids make it seem like all the transmissions are different. Thanks for the help.

Sorry, no info on the tranny question but was the tick from broken manifold bolts? and roughly what did it cost to fix? I have a 2012 that has the manifold tick that stops after it warms up.

So, I need to lead each statement with a full disclosure of my qualifications? I think you are finding social media to be disappointing wherever you go, and you would benefit from rethinking how you approach members of Forums.

What understanding of Google am I lacking?

I thought about my replies but what comes next because I question things will be interesting based on the statements you have made towards me. Cheers

That's common practice and a standard yes.
