Inline serviceable transmission filter Sign In

I have a 2016 Kia Sorento LX AWD V6 that has 48k miles on it. At 35k, I checked the transmission fluid condition and it was practically black. So I did a couple of drain-and-fills at the time, and the condition looks much better when I last checked it at 48k. I actually posted here while I was doing that, as I had a venting issue when filling it back up.

As far as I can tell from the service manual, there's no serviceable filter to replace. This concerns me, as I would like to keep the car for 10-12 years if possible (and not have to replace the transmission along the way). Do you gents think it would be worth installing an inline filter along the return hose from the transmission cooler? They're certainly cheap enough, and I don't think it would get in the way of anything. Just wanted to get your thoughts, thanks.

Re: Inline serviceable transmission filter Sign In

? When you found this with BLACK fluid why didn't you complain under warranty or did you and got some run around? I'd be reluctant to add a filter to a cooling line just because it shouldn't be needed nor going to save anything.


BLACK! If you really meant that there's a problem that changing it just bought time or this was subject to some abuse (you, another or unknown) that burnt it up just didn't totally fail but a horrible sign so early. I'm just going on black fluid = slipping clutches and bands or way overheated and much to new and low miles to write that off as any kind of normal,

Re: Inline serviceable transmission filter Sign In

I found that some of the newer transmission fluids are dark in color right out of the bottle. If the fluid was dark and smelled burnt, then it is too late for any kind of filter because it has burnt frictions inside the transaxle.

This transmission uses a special fluid called SP-IV. Hopefully Gary has more information.

Re: Inline serviceable transmission filter Sign In

Thanks Tom. It was very very dark brown.. almost black, but not scorched in my opinion (I've seen burnt atf fluid in my girlfriend's vehicle, and mine wasn't quite that bad) Of course the dealer said it's normal, and pointed me to the owner's manual, which says the fluid will become darker over time. I know that it does darken over time, but mine looked very dark.. not just reddish-brown like I've seen in my previous vehicles.

I bought it used, and it came from a rental fleet, so I'm guessing it was subject to some abuse early on. I just checked the condition of the fluid at 48k, and it looks clean and red. So hopefully it was just a case where a previous driver was really rough on it during the first 15k. The other possibility is that towing my boat (which is well under the max towing weight of the vehicle) put some added stress on it. However, I probably towed it a total of 4 times (each trip lasting 30-60 minutes, and no ridiculous inclines or anything) before I checked the fluid at 35k.

I actually took another look under the vehicle yesterday when I was checking the fluid condition, and there's not as much room as I originally thought there would be for an inline filter.. good to know that it probably wouldn't do much anyway. I'll just keep monitoring the condition of the fluid closely every 15k miles or so.

Thanks.. in my opinion, it wasn't burnt. It was just a lot darker than I've seen in my previous vehicles, so I was concerned.

Re: Inline serviceable transmission filter Sign In

You called it "practically black" up top. OMG - it's new for the independent folks would be looking up anything that changed and DS said fluid was a specific type would only use exactly that quite possibly pay for it at a dealer so no questions about it.
Later you said it's lighter now so if this was normal and you messed with it IDK where this is going or what troubles you may have caused if the wrong fluid was used - OMG!

I used an SP-IV compatible fluid (it says it right on the label). I was careful about that. The owner's manual also says it's red to start out with..

==========
Automatic transaxle fluid color is
basically red.
As the vehicle is driven, the automatic
transaxle fluid will begin to
look darker.
It is the normal condition and you
should not judge the need to replace
the fluid based upon the changed
color.
==========

Like I said, I expect older fluid to look somewhat darker, but not very dark dark brown (i.e. practically black).

Re: Inline serviceable transmission filter Sign In

OK - So another brand says compatible and might be. Seems there wasn't an issue from the beginning now. Color is almost always added for identification or an attempt to. I still see containers saying on them "compatible with" XYZ but this new do want the exact match.


Back a step: When to change ATF? Read suggested intervals in owner/operator's manual which should say a distance and how long by time plus usually "normal" use and severe use which is 99.9% if you read what they call "severe" is about anything you do if driving it at all.
Just for the time frame what month and date was the vehicle built should say on driver's door jam? To me that's how old a vehicle is not the model year if just looking for time it's been around that long anyway.
I still don't know why the first time you didn't consult dealer service @ 35K on this if just to ask it to be checked out?


Sorry - I worked for a new car dealer for a short time as that job stunk and ancient history I guess now. Vehicles weren't ready newly delivered so new sucker (moi) gets the check to make sure fluids are full, tires have air, remove shipping junk, put some fuel in the thing and see that everything on long list was right. New they didn't stop and fix crap the dealers did if stupid things were wrong and obvious. Those ways are long done with. It was a treat if that new model year changed anything totally from the same model by name than the year before double check sure enough one thing changed.


Car is ready except for shipping protection stuff TMK is lots closer to ready to deliver to new owner.
Problem I have is you messed with it now so if a real problem exists at all wouldn't they love to say it's NOT their fault you messed with it? Warranty work pays squat they would love things to be on you hate to say it.


So if full and drives fine now probably just forget it. Color could have changed by brand and be fine you did the watching for that. If nothing wrong except this fear of the color think you should just stop now and carry on any maintenance that is suggested clearly for it. There are things they can't back out of for powertrain issues, defects and recalls beyond miles and time just nicer all around if you got it new it hasn't been messed with and a filter in line is messing with it,

Re: Inline serviceable transmission filter Sign In

Hello,
In my opinion as a transmission shop owner, i dont care for inline filters, when ever i get one in that has it i eliminate and run a line, the filters are very hard to clean and had issues in the past with them. Being the fact that its your car and you want to install one, thats fine, i would change it every 15k miles. This transmission has no pan and you cant change the internal filter all you can do is drain and fill the unit. Gary
The fluid for this unit is dark in general

Thanks Gary. Just to confirm: when I do a drain-and-fill, does the new fluid just fall back to the bottom of the transmission housing? If so, would it be fine to do the drain-and-fill (to clean off the magnetic drain plug), then disconnect the outlet hose from the ATF warmer and proceed to flush the old fluid that's still held in the warmer itself (and any old fluid held in the torque converter)?

Re: Inline serviceable transmission filter Sign In

Hello,
You fill this engine off til the fluid runs out, then start the car, at this point the filter picks the fluid up, fill til runs out. What i do is a drain and fill maybe 2 times, instead of taking the line off, fluis is usually pretty clean at that point.
