We all know you consider yourself the one and only real expert. But some of those videos are my experienced garages and
at least experienced mechanics. The procedure is the same for most all of those videos, at least the several I've viewed.
Some of us know that there are often more ways than one to do most procedures including transmission fluid changes.
NONE of them claim that they are changing ALL the fluid, some say exactly that. I know how a TC works, I've seem them
cut open. How would that change anything?
Don't let the certificates on the wall go to your head. OOPS! to late.
Well there you Dennis your problem... reading comprehension. Nowhere did I say that a DIY should not do a pan oil and filter service. In fact, I often recommend it on this and about a dozen other forums. ROLMAO.
Next time you want to argue with me on a service procedure that you apparently have never done yourself please do us all a favor READ MY RESPNSE INFORMATION CLEARLY.
And NO there is a right way and wrong way to do any service work oh and the ways posted on forums. LOL . There are short cuts with some but when you totally disregard some aspects of a service it is still a WRONG WAY to do something!
we all and mostly me is why you have not actually gone on your keyboard and looked why DIY should do a full fluid replacement at least without the assist of a experienced Technician and a Transmission service machine?
Now how about start responding in the future with some better service information that you actually have done and know at least they worked for you?

So we circle back to the original about doing a fluid and filter change, and now you "often recommend it" yourself.
Your initial response to the OP was: "I recommend that you simply do another pan fluid change at 5k miles .."
Yet other 'experts' suggest just drive a few miles, say 5-10, then repeat the change.
That sounds more reasonable to little old me. that gets the majority of the fluid changed without wasting time.
the 'rule of thumb' is one change gets around 50% of the old fluid out, the second raises it to 15-70%.
Your expert opinion would no doubt change that.

I strongly advise changing the transmission oil and filter at 25k intervals or less. I have also way recommended this on forums for the last 20 years.
I have never had member on a forum argue this and the ridicules way some do full oil replacement until the internet NERDs wanting a high hit count on their videos.
You are confusing how the dilution factor works. The number are close for a fluid replacement but you FAILED to account for the contamination of the new oil. Your numbers like most doing this way of thinking are wrong. When you introduce new fluid to old the new fluid gets contaminated 100% So now scratch you head and figure out mathematically how many times you would have to drive a little and then change only the pan oil before you have uncontaminated oil. LOL.
The reason for doing more pan oil and filter changes is mainly so you can keep an eye on the oil as well keep the pan clean. Varnish build up is one of the leading causes for transmission problems. Also in this time period we live in oil samples are cheap insurance to test the oil and know what is going on so if something needs addressing you have indicators in advance. Somehow I can't even see you only changing engine oil and not the filter and by your and other way of thinking drain only 1/4 of a quart! lol
Denis this all goes back to members will do what they want and they will read the advise of who they want. I have seen nothing the shows you have any personal experience on this subject only post what you found on the internet. What does that in itself say? On this very forum I have done the transmission service and posted detailed pictures along with at least 2 oil anylisis of my own MAZDA. Where is you 's? Oh wat .. there isn't any!
@ 29213 MILES my TRANSMISSION Basic Filter and pan fluid change.

I just wanted to play around with separating the goo from the metal on the magnet just to see how much there was.
Now mind you hopefully on the next oil filter change I should not see any where near as much wishfully thinking none at all?

You cant argue empirical DATA
The engine oil I am a fanatical about changing the oil at about 3,000 miles and will continue to do so. However analysis shows that my early oil and filter service does rid harmful material. It also suggest that extending to 5,000 service could be done. This leads to possible consideration that oil change and service intervals after a few early miles in servicing them you could go longer possibly 15,000 miles. But I like my number and results on both the transmission and engine for me servicing at much earlier then recommended oil and filter serving.
I drained my automatic transmission on my CX-5 and filter. But just changing half seems kind of incomplete. There has to be a way you and suck all the fluid out. All I have seen is that you have to change fluid several times. Gets expensive to say the least. And Ideas. Maybe through the cooler?
The service you are contemplating should ONLY be done be a shop that has a Professional Transmission Service Equipment. It is possible that attempting to do a DIY complete fluid replacement could damage your transmission. Most shops charge about 150.00-350.00 for this procedure. But because of the cost it would be better to go with an analysis first you may find that the only thing you need to do is a couple of fluid pan service and maybe 1 more pan and filter service to go another 50k miles before the next service?
Most all analysis done between 25-50k shows break in lubricants, and metal material. This remaining circulated through the transmission until you get a couple of pan filter and fluid services. That is why it is really important in maintaining the best operation of your transmission to get a pan filter and fluid service at 50k miles. The filter in the most transmission do not catch all the material that get circulated, and a lot of material settles and collect at the bottom of the pan during it service life.
I had a couple of my * good friend and colleagues read this thread today. They suggested that one or more members may not have understood my first response even though I separated my response information paragraphically? So I highlighted in RED what I was exactly responding to regarding a FULL OIL REPACMENT
I hope this helps a little.
*Both my friends are in the transmission service business, one owns a well known Transmission Service shop Established in 1985.
I posted the comment for general information that there were videos showing the process, which it seems isn't any different than what you do.
Videos for most any procedure for most every make or model.
You crapped on that, with no basis in fact about what was wrong with those videos, yet you didn't, or couldn't say what was wrong with them.
Easy solution would be for YOU to make a quick video showing how a EXPERT does it.
No one, certainly not me, suggested that fluid analysis wasn't a good idea. Most folks won't do one for their transmission fluid, though many do so
for engine oil. SO?
I'll let you have the last word as you love to do that.
[QUOTE=Dennis Wendt;208933]
Yes I do. Dennis I wish you would post things that you have done instead of going a crusade with information you don't even apparently understand or have done yourself. You and another member tend to do that a lot on this forum and another, often posting others information? I cant even remember if you have ever posted a real factory service procedure? You still are not reading my responses and only taking what you want from them. Actually if you pull your head out..... you would see there is a lot of information that even you could look into and perhaps cross over to supporting my responses? Wouldn't that be funny! Dennis your stuck in a gear of questionable information so to say, LOL maybe it time you get your oil changed and have your biological ECU updated ? hahahahahaha!
As for me posting a how.... There already is several bonified and proper service procedure already available. I think I contribute 99% of my information backed with personal pictures on threads I participate in.
Here is the thing not once did I see you even hint that you looked at video warning not which when I type in Gogal both the DIY as well professionals are posting videos . The professionals are the ones saying not to and why.

I'm planning on draining and refilling the fluid on my wife's 16 CX5. Can anyone tell me approximately how many quarts I'll be replacing so I have enough on hand? I know I am not getting all of it out. Just looking to replace whatever is in the pan.

According to my mechanic, pulling the pan and using sealant when replacing it is the problem. If a bit of the RTV sealant breaks off it can clog a solenoid or lubrication passage. He has seen enough transmissions where this has happened that he doesn't recommend that it be done at all, especially by DYI'ers. Take it easy on the tranny and it will last without lube changes.
