Should You Ever Replace Your Transmission Filter?

[@am74343]

Every single metal-on-metal surface or clutch/band assembly constantly produces microscopic pieces which break down with every single revolution of the gears. Those pieces eventually clump together and form varnishes due to the heat. That varnish clogs the filter, and reduces the line-pressure of the transmission slowly over time. I still believe in the old rule-of-thumb. Change the fluid and filter once at 30,000 miles to remove the initial break-in wear, then change the fluid and filter every 60,000 miles thereafter. The amount you're spending on a filter and fluid is far cheaper than having to buy a new transmission because it was not maintained.

@@PetesGarageandperformance anyone who works on transmissions for a living should know that it is an important part of vehicle maintenance. Not as often as oil but almost every vehicle has it in there maintenance schedule. Every 30-50k miles transmission fluid change and filter change is to be done. You are making videos on something saying you don’t need to do it when every car manufacturer in the world says it is routine Maintenance and SHOULD be done at a certain mileage..

[@emuhill]

That filter is to the cooler. If you don't change it, you will overheat the transmission eventually. In fact I came across a garage that apparently thinks the way you do. The result was the cvt overheating and going into safe mode because they wouldn't change the filter. I started doing my own cvt fluid changes after that. After I had that filter changed, no more overheating cvt. Why does that filter need replacing? The fluid breaks down from the engine heat and hence why the fluid has to be changed. Also the transmission has wear just like the engine does. The older the fluid the more wear that occurs. That filter is there to filter out small metal particles and to keep them from clogging up the transmission cooler. The filter can only hold so much and must be replaced or else the fluid flowing through there gets restricted. There are also one or two magnets in the transmission pan that need to be cleaned of the metal particles when the fluid is changed.

The trend is going away from changing fluid/filter because the vehicle is only designed to get you out of the warranty period. That’s the “life” of the vehicle to the manufacturer. So if they engineer it so that 85% of all the vehicles made can double the warranty period ( let’s say warranty is 100k but 85% will get to 175-200k miles) without ever opening the transmission. 97% will make it through the warranty period with no issues. That’s all the manufacturer cares about. You get 150k miles and your transmission goes out you either drop 4-8k to have another one put in or go buy another 60k vehicle. Simple.

Change those transmission filters between 60k to 90k depending on how hard you drive, weight you haul or trailer towing. Clean the trans oil pan. I have seen trans filters plug up & damage transmission. Transmissions are very, very expensive to replace & usually not as good as the original. The transmission is the most expensive part of your vehicle & will leave you stranded needing a tow, costing you over $5000, so if you want to be sure it last forever, install a transmission cooler & change the filter. Heat is what destroys 90+% of transmissions. Dirty filter will starve fluid pressure causing clutches to slip & destroy the transmission.

I totally agree with you. Most transmission filter will only filter to maybe 100-200 microns size particles. Most clutch wear particles are smaller than that & go right through the filter. I dissected a transmission filter on our '07 BMW X3 with the French made GM transmission, running Dexron VI fluid, and had 132k miles on it. The filter almost looked new. I had to check the date code molded on it to see that it was the original filter. Also, the magnets pick up most of the steel particles, the clutch particles will eventually settle out & adhere to the pan vis surface tension. That's why you have to wipe them clean. So, IMO, a "drain & fill" will do the trick. I do it about every 10-15k miles which replaces about 40% of the fluid. Thanks for you video.

[@MidnightMarrow]

I do agree you probably don't have to change it near as often as other filters, I'd think after two fluid changes you should definitely replace it. They say fluid lasts 60k miles yet I don't think I've gone over 10k on a fluid flush and it's already discolored to the point I need to change it again. ATF may not be subject to fuels and the like but it still gets hot specially in the summer and breaks down and the more it breaks down, the ability to dissipate heat and lubricate lessens and thus more wear on the parts.

There will always be a normal amount of clutch material wear. The filter makes sure that this doesn’t get into the pump, valve body, cooler, etc. There is enough surface area in the filter media to accommodate this “normal” amount of clutch material. If there is more material/debris than the “normal” amount, you would have shifting problems. Then it would need to be rebuilt anyway.

[@justhere4721]

Depends on the vehicle. Some cars are easy and cheap. Like my Infiniti G35, the filter is right underneath the drain pan and cost about $10. So if you have high miles and your removing the drain pan, might as well change it while your at it. Others might not be necessary unless your rebuilding due to the filters location.

[@jeffumbach]

If you're already need to remove the transmission pan like to replace a damaged pan or leaking gasket, otherwise you just created a bunch of additional labor for yourself as now you need to replace a gasket and remove and retorque a couple dozen additional bolts that you otherwise didn't need to touch.

[@cgrscott]

Changing the transmission filter can cost over $300 in labor, parts, and new ATF. If you change the filter and fluid yourself, it's a more cost effective measure. Changing the Transmission Filter is cost effective insurance compared to paying a mechanic to rebuild or replace a spent transmission. On my 2006 Siena and my daughter's 2002 Camry, I have to unscrew the left engine/transmission mount and rock the engine upward, with a bottle jack, to access the transmission drain pan screws to get to the transmission filter. It's not a quickie job for a mechanic so, to avoid paying for the labor involved, I do it myself.

The transmission is still metal on metal contact, it doesnt have to be a catastrophic amount of metal that comes off. You still have to change the filter, since you only need to change your transmission fluid every ~ 60k miles, its not that big of an issue to spend $70 on a new filter. If there was a catastrophic failure, the filter is as reduntant as the bolts holding the fluid pan. youll need 2k for a new trans, however if you dont change your filter and those metal pieces make their way back into the transmission, that could potentially be the CAUSE of the catastrophic failure. Again, you dont change your transmission fluid that often as engine oil because theres no need, so it shouldnt be a point of saving money since the spacing between when you do it is fairly large

[@PetesGarageandperformance]

I agree that if you are into the transmission that you should change the filter. But you don’t need to drop the pan on most transmissions to change the fluid. They either have a drain or you can use a fluid exchange machine using the cooler lines (my prefers method). When I worked at the dealership we had two options: just a fluid flush with the machine, or drop the pan to change the filter and then do a machine flush. It usually would cost an extra $80-$100 to do the pan drop and filter. They don’t put a filter on manual transmissions or differentials. All they use is a magnet to catch debris. A filter is used on automatics because they have to keep the pump, valve body, cooler, and piston seals clear of metal debris. However, if there is more than the “normal” amount of debris that the filter is designed to handle, the transmission needs an overhaul that changing just the filter won’t fix.

[@GregSr]

Pete, I completely agree with your logic. In my case, changing the filter in my C4's automatic is what actually killed it. My fault 100%. I didn't remove the old O ring before installing the new filter. I think I damaged it while trying to dig it out. That allowed air to be sucked into the trans fluid. After doing a 1/4 mile run, the trans started slipping real bad. The first thing I did was pull the dip stick. The trans fluid was loaded with little air bubbles. After letting it sit for an hour, the trans started working normally again. But, the damage was done. Under certain high throttle operations, the trans would slip and not upshift. In hindsight, I should have never messed with the original filter. Now, in my 96 Impala SS and my 2003 C5 Vette, I leave the trans filters alone. The trans in my Impala made it to 270,000 miles before I had it replaced.

[@lesliegloyd3172]

It wasnt changing the filter that caused your problems with your trans. You made a mistake not the filter .... mechanics error.

[@voidisyinyangvoidisyinyang885]

thanks for sharing. The dealer tech put the rebuild flush amount of oil back into the transmission after a pan drop. I had several EXTRA quarts and also had tons of air bubbles and burnt smell. I did a trans flush after that and they confirmed what I had seen at the dip stick - several extra quarts of oil from the Dealer pan drop, filter change! My transmission failed soon after the flush but it was definitely caused by the dealer tech error. Since the transmission had the rated 275K miles on it and I was just trying to extend the life of the transmission I didn't pursue the dealer error. But your story confirms that as you say, "the damage was already done." I got a rebuilt transmission - for a few thousand dollars. They put in new cooler lines also though at my request. I'm now 10K miles later and so figuring out if I should change out the filter myself...or do a flush before the fluid gets burnt without changing the filter at first...hmm.

The only reason the filter is replaced is that you had to lower the pan to get the fluid out and so if the pan is already off why not just replace the filter anyhow. If, however, you have a drain on the pan and the transmission is working correctly, just change the fluid. If you are really worried about the fluid quality, then replace the fluid in the pan via the drain more often. I installed a drain in my pan by using a roofing sheet-metal screw. It takes a little while to drain the fluid through the rather small hole but it seals as it should. The screw cost about a nickle.

If the filter doesn't catch all the contaminants and the contaminants get into the valves the valves can get blocked causing damage to clutch plates. Clutch plates usually get damaged by putting extreme usage on the transmission such as spinning tires, hauling trailers, or blocked valves which cause overheating of the fluid. Filters do get clogged with clutch contaminants and metal as the magnet in the pan gets to the point where it can't pick up any more metal after being coated with wear and tear metal bits over time. When the filter gets gets clogged with clutch contaminants and the valves stop working and vehicle won't shift between 1rst and 2nd or 2nd to 3rd, most people think the transmission is completely gone but it can have another 50,000 miles on it and just need a valve replacement and new fluid replacement.

[@podamis314]

On old but well functioning transmissions the pan usually has a coating of viscous dark material and so does the filter. It seems probable that this is from the clutch and band coatings due to normal wear. Is it possible that new fluid with additives at full strength can resuspend some of the finer particles and circulate them? Then cleaning the pan and a metal screen type filter in solvent seems likely to remove most of it and lessen the wear, since these are the lowest points.

[@MaliceInCyberland]

Many replies were general common sense reasons to change the filter, but you made a really great logical point that I've never heard anyone say. Maybe some rare person doing a drain and fill every 20k could probably get away with not touching the filter for a long time. But after 60k+ miles of unchanged trans fluid there will be some sediment... and after 100k there would be a lot. It makes total sense that new fluid with cleaning additives would resuspend that sludge back into the transmission doing a drain & fill if the pan wasn't dropped and cleaned at the very least. But at that point why would anyone not change the filter which is easier than removing the pan? The only reason they've invented lifetime trans fluid that never needs changing is for environmental tax breaks, and tariff reduction on imports; it's true. But that really makes sense what you said, and the reason I'm adding a trans filter to my fluid order for my upcoming drain & fill. Thanks!

I had a 1990 Ford escort. I pulled the pan off at 125k. Had drained the fluid and replaced at about 75k. I had noticed that the transmission was starting to slip. Grant it I was not hot rodding it but I noticed it. I took pan off and replaced the transmission filter. I cut up filter. The fine screen inside was completely covered with tiny pieces about 1/8 deep. Was blocking flow. After replacement went away. Easiest car was 1996 Saturn,. External transmission filter. Same size as oil filter. Cost about the same. I changed every 20000 miles. Never had issue. Had that car up till 225k. Finally sold because AC went out.

yes, if your transmission filter gets clogged and needs changing, you need a new transmission.

Needing a new tranny and engine is never a good thing bro but it happens

[@harvestblades]

As someone who had run many Jeep Cherokees with the venerable AW4 trans it is pretty common for guys to just drain & fill the trans at regular intervals & still get 300k or more out of them. Even if we are not towing, climbing, or rock crawling the short trips, stop & go, idling in traffic is hard on the trans so we should service per the severe use recommendation. If you're not spending hours pulling, removing gasket or RTV without scraping the mating surface the time saved & lack of dread will more then make up for using better fluids & even changing more frequently. I've never cut one open, but on the AW4 the filter is a coarse screen & functions primarily as a pickup. Also I don't see it being critical that the magnet is cleaned when the fluid as changed as its general a strong magnet & will hold plenty of clutch material. Thanks for taking the time to tell me what I wanted to hear!

[@sergioburrola7908]

The reason why the filter needs to be replaced is because all the parts will very slowly wear over time creating very small particles of metal and the filter catches all those particles over time, catastrophic failure is different and does not parts are not being worn out even with good oil in them.

[@JA-rn5qv]

Have you ever opened up a transmission filter with over 100,000 miles on it and inspected the filter media? I have several times and there was virtually nothing on the filter media itself. The filter can catch any larger metal particles from when the car was new and the transmission was going through the break-in process but the very small metal particles will go right through the trans filter (it's not like a motor oil filter). Many trans filters are nothing more than a metal mesh/screen. Worn clutch particulates also do not get caught by the filter but instead get suspended in the trans fluid itself which is why it's a good idea to change the trans fluid regularly and in most cases and shorter intervals than the manufacturer suggests. In many newer cars, the trans filter is no longer even accessible but instead built in to the trans internally and on accessible by completely disassembling the transmission because the filter is only meant to be changed once the trans itself needs rebuilding.

[@philliprawlings8572]

You are absolutely right. I drive a 2017 Chevy cruze, and to change trans filters, you have to take the whole thing apart

[@manniemaneii5226]

The filter filters the shavings. If there a certain amount of shavings in the filter, it will hinder the flow of the fluid. So if you're changing the fluid, why NOT change the filter as well. It makes absolutely no sense to have clean fluid flowing through a filter saturated with blackened fluid.

[@weirhauch1002]

I have never changed the transmission filter on my Mercedes 2000 model c class .I only add trasmission fluid and it is working fine .Thank you for your logic 👍🏻

[@chadcollier1070]

It depends on the vehicle, how many miles it has, and how long you plan on keeping it, because if it's an older vehicle you plan to keep for awhile, then yes, a filter and fluid change will come into the picture at some point, simply because if you change the fluid and not the filter, the old filter will dirty up the new fluid faster.

[@ronaldballard4362]

new fluid is not going to dirty a filter. only in a dusty environment.

[@oldelectronics70]

I think Pete is right, fluid is what is really relevant. However, I still would change the filter every 3 or 4 transmission flush/drains assuming you are doing it at the recommended intervals.

[@benicavalera2543]

since its a closed system, routinely change the trans fluid every once a year (approx 20k km, whichever came sooner) will keep the trans in good shape. so just like you said, if the trans filter is clogged, then it surely means the owner rarely change the fluid -> problems in the trans..

[@mongo64071]

I agree. For example Honda v6 Pilot circa 2007 had a transmission filter that was not serviceable. It was internal between engine and transmission.

Somehow transmission fluid are known to turn black and dirty. If you don't change the fluid soon enough the filters will be very dirty and prevent fluid to past through the transmission.

[@darrenbishop5544]

Hey Pete I do agree with what your saying about filter in transmission. Ive got the 3.6 and the auto has no drive. After dropping the pan I can clearly see its never been opened. The filter itself was holding the finest and the kitty litter sized pieces and smaller filings collected on the magnet. In seeing that i could confidently say shes seen better days and a refit is called for. Plus a new filter.

You are correct for simple metal mesh filters, but some have a multi layers filter like post 2011 Mercedes 7 and 9gtronic. There is a paper like layer to catch thinner dust and I think for this type of filter it is better to change the fluid and the filter

It doesn't cost that much you might as well change your filter this way you don't have to worry about it

[@StanZeMan]

I agree with your reasoning. Totally makes sense. Two other things I assume add to your arguments are that the filter is probably designed to have enough surface area to handle normal amounts of wear materials and if there is a magnet in the tranny, it will catch most metal normal amounts of magnetic metal particles.

Periodic drain and fills. Swear by it and have had cars and trucks both run 400k without a hitch. Even if pan removal is a pita I’ve pumped out and pumped back in exact amounts. Wala fresh fluid !

[@keithfazekas205]

Only way to know if filter is getting dirty is from pressure drop test from before and after a filter. And yes a filter can have dirt or metal inside and still be doing it’s job. The filter shown in video is just a sump pump screen and not a true filter. Sometimes behind a attached cooler is an actual small filter that definitely should be changed because of physical small size. Any filter change can help with slightly better flow or pressures helping last longer life for the cheap price of filters!

[@clydeespinosa6286]

When my truck was just 8 months old, the transmission was acting up. When the mechanic dropped the pan, he said there was a lot of debris in the pan. They did whatever they do and I have not had a problem in 16 years. But I do think about replacing the fluid and filter.

[@hazaqames477]

Interesting! My 2008 HHR user manual footnote 'h' says "Change automatic transmission fluid and filter if the vehicle is mainly driven under one or more of these conditions: (1) in heavy city traffic where the outside temperature regularly reaches 90F (32C) or higher. (2) in hilly or mountainous terrain (3) when doing frequent trailer towing (4) uses such as found in taxi, police, or deliver service. It also qualifies this maintenance task as a 50k, 100k, and 150k "severe service only" task.

[@Howard-xc5ou]

People are saying he is not making sense but he definitely knows what he is talking about. Think about it why would a manufacture seal a filter inside the tranny if it needs to be changed during routine maintenance?

[@thatchertrudell6195]

I think you should change it one time during braking and then not touch it again since the break-in would cause the most fragment material

My 1998 Lincoln continental’s transmission was making a high pitch whine sound from the trans front pump. I dropped the transmission pan. And put a new filter in, loads of metal mud on the magnet, swapped the filter out and added new fluid. Now it makes no noise and shifts better. I’m at 210,000 miles.. for what it’s worth.

[@p.b.9428]

Pete's right. This is not an oil filter that filters down to at least 20 microns. Unless you're installing a Magefine filter or something similar to the transmission hose line, the fluid is literally passing through mesh or sponge, both of which are designed to catch shavings and the like.

[@notimporta3416]

I'd say you're right in general ,though I'd stretch the oem cycle from 1:3 so potential shavings would not factor performance if given. You have far than a stilled mind your stated claim is proof along your altruism.

[@attocoulomb]

Depends on the transmission and the filter. Once I saw the filter in my wife's QX4 (aka Pathfinder) was just a "rock catcher" screen, I knew it wasn't worth replacing. Other transmissions have real filters. Do you think that the material in a real filter is not going to fail in 20 years/200k miles (which is less than the last two cars we had, bought new)?

[@steverayrapp]

I change the filter the first time I do it and replace the pan (If available) with an aluminum finned deep pan with a drain plug. I just do fluid drops every third oil change. Dorman makes replacement pans that are actually very good with drain plugs. If you own a Honda the filter can't be changed without major disassembly.

I changed the transmission filters and oil in every vehicle I owned except for 1. It was a Ford F-150. Transmission failed at 81,000 miles on the F-150. Other vehicles included Dodge Durango Ford Explorer 3 each Dodge Ram 1500's Dodge Charger R/T I only changed the oil and filters in the 3 Dodge Ram 1500's The other vehicles were done at the dealership. Could be just coincidence but the only vehicle that I had transmission problems with is the one I never changed the oil or filters in the transmission. Note: My son had a dodge Ram 1500 and never changed the filters nor the oil in his transmission and his transmission went out as well. Not sure how many miles he had on it though. His truck was 2 years younger than one of my Dodge 1500 truck. I know have a Dodge Ram 2500 with the 6.4 liter HEMI It is at 60,000 miles and many may think this is too soon to change the oil and filter I don't. It's an easy job and only cost $100 for the fluid and filters. I tow a camper with my new truck and don't want to have trouble on a long camping trip and that is why I am changing the oil and filters. I know many will disagree but this is how I roll !

This is so interesting video Pete. I changed the trans fluid a year ago(it had never been changed), when I bought my car (128i E82 84k miles) because I did feel some vibration in specific RPM and gears. The dealership told me the problem is the transmission and we should start from changing fluid. They told me that the drained fluid was quite bad and there were some metal debris but after changing fluid my car turned to drivable. But what I got shocked was the dealership doesn’t exchange the filter and pan, they just drain previous oil and refill. So, I was thinking that I should exchange the filter, pan, obviously fluid again because there are still highly likely some metal debris in transmission. However, based on your opinion, do you think I should not or don’t have to re-change fluid and etc? I’ve only drive 6k miles after I exchanged. @Pete’s Garage

[@brentneves3602]

All filters regardless of type or brand have a limited life span of usable service, beyond that point, the very molecular structure of the filtration medium will breakdown, become saturated with normal amounts sediment reducing it's effectiveness over time. Im completely lost as to why the hell, would anyone drop the pan, to change the oil and not change the filter also, for the inexpensive cost and the time it takes to do, your point is totally irrelevant. Yes around 40% of the fluid does remain in the torque converter, but adding 60% new oil still introduces a nice fresh batch of additives that normally lose their strength after 80,000 kms, what ever remains in the TC will dilute into the fresh new oil, and the new filter, will clean up any suspended particles, giving your clutches, valves, solenoids, seals and torque converter extended life... If you are smart enough to rebuild a transmission, then you are certainly smart enough to know that the filtration medium, does indeed break down over time and begin to plug up or reduce its micron screening ability.

[@PetesGarageandperformance]

I agree with you about if you drop the pan to replace the filter while you are there. But I wouldn’t waste the time and would do a fluid exchange through the cooler lines instead. If the filtration media does indeed break down to the point of needing replacement, why would the engineers bury the filters inside the cases of the newer FWD transmissions?

[@ihd-3603]

I always wondered why they didn’t have a drain plug in the pan and the return filter on the outside since that’s usually the one that needs changed most often. Then you could drain the fluid and change the return filter every 30,000 and dump the pan, clean the magnet, and change both filters every 60,000. The sump filter is more or less just a screen and usually isn’t that dirty at 30,000. It actually doesn’t take much dirt and clutch material to plug some valve bodies and for shift solenoids to start sticking. Also, restricted flow from a plugged filter will cause more heat which is what destroys transmission fluid the quickest.
