I went to a transmission shop to do the flush. My car has 100k miles and I have no idea if the previous owner maintained the transmission or not. After the service, my transmission is more responsive and smoother. I don't know if I've got lucky, but the flush improved the gear shifting and smoothness of the ride.

@leesmith9041 2 года назад

Great! From here forward, maintain the fluid by replacing part of the transmission fluid at each motor oil change. Get a hand operated transfer pump for $10 and extra hose to extract fluid through the dipstick snorkel. Do the same for the steering fluid.

@danielgriff2659 Год назад

You probably said flush and they did a drain and fill and charged you for the drain and fill. A flush can ruin a transmission so they usually dont want to do that. A flush means they use pressure to clean it out, and that pressure drives dirt DEEP into the transmission. A drain/fill avoids all that.

@anonymike8280 3 года назад

Another little tip. If you have a vehicle where the transmission pan, does not have a drain plug, sometimes you can buy a replacement pan that does have a drain plug or find one in the wrecking yard that has a drain plug. Or you can drill a hole and install an aftermarket drain plug. Once you have dropped the pan and installed a new filter, likely you will never need to do so again. You will only need to drain and fill every 30,000 miles or so. A drain plug will make that very easy.

The worst vehicle I've ever owned regarding the difficulty in changing the ATF was a 2008 VW Rabbit. The drain/fill plug was in the bottom of the sump pan and there was no way of measuring it with a dipstick. It was a complex procedure requiring many steps. The Aisin 09G transmission worked flawlessly but changing the fluid was a PITA. The easiest I've owned is the Gen 1 Ford Escape with the CD4E transmission which had a drain plug and dipstick.

As someone who has spent many years in the transmission repair business, most people don’t think of servicing the transmission until it starts to shift different or starts to show problems. If the trans already has issues, of course changing the fluid won’t help. That would be like putting a Band-Aid on a gunshot wound. I change the fluid and filter on my Dodge cars and trucks every 50K, adjust the bands where needed, and all of them have gone at LEAST 100k before I traded or upgraded. My current 06 Ram diesel has over 200K of hard towing, still going strong.

@tssci6774 4 года назад

My daughters Saturn had 210k, it was burnt, brown, gritty and oil analysis showed huge amounts of wear metal and clutch material floating around. It also shifted hard. The flush fixed the problem and no problems, and it shifts much better. This was sealed transmission with no filter to change, that is unless you wanted to pull and crack the case.

Great video! The method I used on a car with a neglected transmission was to do a partial change, and then do the next after about 15 miles, then every hundred miles.

@RJ-vb7gh 5 лет назад

The first transmission fluid and filter change I did was on a car that had jet black burnt and stinking fluid that was slipping... The trans didn't get much better and failed within a couple of months. Some folks might argue that the new fluid killed the trans, whereas I might argue that the new fluid kept it going for a couple of months.... Most of the arguments about new fluid killing a transmission are due to the trans being toast in the first place and the fluid change is a hail Mary to rescue it. For the most part, if the fluid is burnt it's been overheated. Changing the fluid won't fix the overheating problem nor will it fix a trans with worn out clutches. The question to ask someone is why they decided to do a fluid change in the first place. Most will admit it was because their trans was in trouble already... The fluid change didn't kill their trans, it just didn't rescue it. That said, most cars are best off with a filter and partial fluid change as long as the trans fluid still smells and looks good. The clean filter never hurts and clean fluid won't hurt a good trans. Basically by adding about half of the fluid you are removing some of the free floating debris and crud in the sump and upgrading the additive package in the fluid, which isn't usually a bad thing.

@theredscourge Год назад

A transmission going from slipping to being dead in a few months definitely seems like the fluid change wrecked it faster than if you had simply tolerated the slippage. You probably would have got a few (annoying) years out of it with no change. A fluid change can indeed reduce the lifespan of a transmission if it is already very dirty in there and the new fluid, which acts as a solvent, loosens up some debris that was stuck somewhere, and cause it to float around and clog something in the valve body, like a human having a stroke. Never replace the fluid in a transmission that's already slipping, it will never improve the situation, and it will only give a risk of blowing it up entirely. But if you replace the fluid in good time, before it gets to that point, you'll never have that problem in the first place.

@RJ-vb7gh Год назад

@@theredscourge The reason we tend to think that a slipping transmission would have kept working if we didn't change the fluid is because it's the path untaken. As in, if I did nothing, things would be better than what happened. There's no way to prove it. To be fair though, I've seen transmissions go bad and they very rarely last for years once they stop shifting properly. In fact, my wife's car stopped going into third gear occasionally. Two weeks later there was no third or fourth gear at all. The car only has half a million miles on it and is on it's 4th valve body now and is running fine. Fluid is still oddly clear... and yes it was red when we changed it. I think we've changed it about 3 times over the 15 years we've owned it. Similarly, I've seen cars with burnt clutches and burnt oil fail pretty quickly if nothing is done. That said, I drive an old Cop car, the fluid was red, but the filter was full of clutch material and the magnet was covered in metal dust. A fluid change greatly improved the shifting. The car was primarily used as a chase car so lots of sprints wore the clutches and metals. The car has a trans cooler so the fluid didn't get burned. Nothing is going to replace the worn off clutch material and I'm always going to feel the shifts, but with fresh fluid and a clean filter and no more chasing bad guys, the trans is likely to last a very long time as it is not slipping yet, just shifting a little hard. I honestly don't see any advantage to burned fluid in the trans. It isn't lubricating and isn't doing it job. I also don't see a benefit to a clogged filter. On the other hand, I don't recommend trans flushes as I believe you are right and they can flush dirt into the valve body. I suppose.... maybe... there's a compromise where you might change the filter and the fluid little by little... I've also had one case with a posi rear, where carbon caused the clutches not to lock up at all... flushing it with carbon tetra chloride and xylene fixed it right up. I'm not sure that's ever the problem with a trans, and I wouldn't recommend doing it with a trans. In my experience, most people don't do anything with their transmissions until they are literally pushing the car in and then they want a fluid flush and filter to fix it. And no, it never works... it's just too late. If they did the filter and fluid change when the fluid just started turning darker, I believe it would have helped a lot. Lastly, lots of times in modern cars, when a trans doesn't shift, you need a valve body or other less expensive repair... Always have a really good professional check out the trans and stay away from transmission swap shops and guys that change oil for a living.

@kennya51 Год назад

@@theredscourge Hey so what you're saying is that, if i do an oil change for a closed system, and while draining i find out the oil is really bad, it's basically better to put the old oil back in again and abort?

@theredscourge Год назад

@@kennya51 only in the case of transmission fluid do you need to be careful about intervals. You may be able to drain a small sample and see if it's still okay to change it, but it is almost always best to go by the OEM specified intervals or the below guidance if none provided. For any other fluid, an early change won't ever hurt anything. You don't want to change transmission fluid if it has gone over 80k mi or 120k km since last change, because it will start to slip and hesitate when shifting, which is a particularly big problem in the newer 8 speeds as you shift often. You also never want to do a fluid flush, as the debris can get forced into the valve body and wreck your shifting entirely. Drain and fill only, and only on a set interval of somewhere between 50k and 80k mi or 5 years, whichever comes first.

Then two more quarts week later. In another two weeks of normal driving, trans went out almost instantly. I towed to my trusted mechanic of 9 years.

@davidjames666 6 лет назад

Invest in a 1x1x1/4 neodmndym magnet and stick it to the bottom of your pan - in side or outside. Itll keep that grey metal paste out of your valve body solenoids and seals. The factory magnet catches some of the metal pastw, but the substance is allowed to travel through the transmission because the magnet is weak, and only carxhes the material as it settles. The neodmndym will grab it as long as the fluid is in the pan!!

@darrylhowe1465 4 года назад

There are some contradictions here. You say never put in additives; then, you say add Lucas Stop Slip Transmission Fluid. I agree that you never put in additives and that includes Lucas. If you transmission is slipping, first verify the fluid level. If the fluid level is OK, then a fluid and filter change may be in order. As for the comment to never let a shop perform a fluid flush, I agree that using a "flush machine" can (in some cases) cause problems; however, some shops use fluid exchange methods that eliminate the possibility of cross contamination. Regular transmission services that are performed according to the manufacturers procedure and specifications will extend the life of the transmission. The problem is that many people do not perform regular service. They only have services performed after a problem has already developed with their transmission.

If you have a vehicle with a very high mileage and never had transmission fluid change just forget about it, at this point becomes why fix something that is not yet broken...

It has never had major work done to engine or transmission...I bought it with 100,000 miles back in 2009. 1) I was hit hard on the driver side wheel on highway, car went into limp mode. Ever since then, sometimes car went into limp mode, or would not shift properly, or RPMs would jump higher, prevent acceleration, and car wouldn't shift properly. 2) Transmission oil was low, light came on for oil being too hot, only had 2 quarts out of 7 required. This car comes with no transmission oil dipstick, accidentally overfilled oil, it started running out of the overfill slot below the car, and a few times caused severe smoke while driving on the highway. 3) Eventually enough leaked out and burned to where the oil fell within the level, after it was checked at a garage with a dipstick. 4) Went for another drive on the highway, shifting problems continued, and eventually the RPMs dropped, car would no longer drive. 5) I pulled into rest area, turned off the car, waited a few minutes, started car, and began to take off, but the car still wouldn't shift out of 1st gear, so I drove the car slowly to a place where I could park until I decide what to do. 6) After some YT videos, I tried to reset the transmission, disconnected the negative cable for about 1 hr., then I tried taking off but the car still wouldn't shift out of 1st gear, nothing worked. No check engine came on for these transmission problems. 7) After some research, I'm going to replace the down kick switch first, if this doesn't work, I'm going to buy a conductor plate kit with conductor plate, filter, electrical switch, and oil pan gasket. Should I also replace the solenoids? 8) Do you think I will solve my problem with the latter fix, or do you think something else could be the problem? Your opinion would be appreciated, thanks.

It used to be all maintenance manuals said that when you flush out the transmission and replace the filter ,...... you also adjust the bands?

@falcorthewonderdog2758 5 месяцев назад

Flushing or changing your transmission fluid won't cause any damage. The damage is already there the new fluid just reveals the issue. Rule of thumb if the fluid is discolored and still clear change the fluid or flush it. If the fluid has a burnt odor or a cloudy appearance with debris or a metallic shimer like paint then don't service it you need transmission repairs.

@CarFanatic 4 года назад

Great video, but I hope people watching use gloves when handling automotive fluids. Transmission and other fluids are not hand lotion and can do harm over prolonged exposure.

@raymondsmith6315 5 лет назад

Not sure what is a "flush" but I did replace all of the transmission fluid by removing the cooler lines and running the the car in idle and simultaneously replacing the fluid as it was being pumped out by the transmission. 8 quarts came out as 8 quarts went in. This was after I had replaced the transmission filter. I used synthetic trans fluid. I had shudder in the 3 to 4 shift and had hard engagement from park to drive. All of this went away after i did this. This was a year and 13,000 miles ago. The transmission is a A341E on a 1991 LS400 with 360,000. Shift and runs like a champ now.

Bought a Dodge truck years ago with a slight slip when it shifted into high gear,took it to repair shop to have transmission fluid change,they told me I would be throwing my money away,decided to change it my self.drained it and put in a new filter,slippage stopped drove the truck for few years with no problems after that ,turned out to be a clogged filter.

@perry9492 4 года назад

I bought a Ford Excursion in 2011 with 94k on it and it was making a funny honking noise when the torque converter locked up. Flushed the fluid and the problem went away. I have about 140k on it now about half of that is towing and I have had zero issues with it. It is about due for another flush with DIII. If a flush kills a transmission it was toast anyway so don't get anxiety over it. If the transmission is good, it will make it last longer.

Start doing a drain and fill every 5,000 miles for 20,000 miles with high grade synthetic transmission fluid and it’ll clean the transmission safely. Then keep drain and fill at 20,000 miles. Patience is key.

@msmdlcdfvs 11 месяцев назад

So will that clean out all the old transmission fluid, little by little? Normally when you do a drain and fill, you end up only changing out a third or so of the transmission fluid that the transmission calls for.

Every 3rd engine oil change (total of about 15K or less) I drain 2 qts of trans. fluid and replace it with OEM Toyota Type IV. Seems reasonable. No issues.

@Travis Fletcher Why do you say that? It's about 1/4 of capacity, so about a "change" in 60K. Of course, it's just successive dilution, but beats a flush.

@afara2000 6 лет назад

Here is safe way I did to my 130k Camry. Drain and refill 1 quarter and drive 300 to 500 miles. Then drop the pan and replace filter and add ATF fluid. Some old fluid will be mixed with new fluid. After some time either do a flush or do multiple drain and refills with some driving in between. Multiple drain and refills cost more time and money but should be safer than flush. Reference: Honda service manual

@TheSchmed 4 года назад

I bought a manual vacuum and sucked fluid out via the dipstick port, in my 2007 Commander with 120K miles, did 4 qts ran a bit, for a week or so, then did another 3, a bit of a waste as you are sucking out previously new fluid, but worked like a charm. I would say 75% or so of the fluid (mixed with old) is new, shifts and runs much better, old fluid was a bit brown, but no particulate matter was seen, nor was it burnt. I just want to get another 50K out of it. Owned since 10K miles, shifting into reverse was getting a bit rough with a knock, disappeared after the fluid replacement.

@javaman2883 4 года назад

Ratchets and Wrenches I bought a 96 Suburban K2500 at 114k miles. Everything was working fine, I drove it for a few hundred miles to see if everything was working ok. According to the vehicle records, the transmission fluid and filter was changed at a shop at 63k miles, so the fluid had 51k miles on it. The fluid was dark, but could still see some red in it. I pulled the pan, changed the filter, which looked fine, put the pan back and then pumped old fluid and replaced. Ended up putting in 8 quarts of Dexron VI (which is supposed to be backwards compatible with Dexron III). Since then, when it's cold it drives great, I can drive 65 up a 4% grade no problem. Once it warms up I lose 4th gear. Going into 4th, I can feel the shift and see RPM drop, then after a couple seconds it just seems to be in neutral, can't even maintain 40MPH on flat road. I used my scanner to show transmission fluid temperature, the loss of 4th gear happens when the temperature gets up to around 90-100 F. If I move the shift lever to 3rd, it drives fine, no issues as it does not even try to shift to 4th. I've been driving like this for several thousand miles now. I've talked to all three transmission shops in town (it's a tourist town) they all want to rebuild the transmission for $2800 to $4100, which I don't have, and am not interested in their 25% interest payment plans. I've read in forums online other people have had problems running Dexron VI in older vehicles. Would you recommend changing the fluid out for some Dex/Merc fluid that's higher viscosity than the Dex VI or should I just leave it and keep driving it as is? The fluid now it still clean, after a few thousand miles.

@Claysvids 5 лет назад

Geeze, such a complicated issue. I went back and forth on my transmission in a GMC acadia 2014 with 99k. I bought it at 55k. Unsure if the transmission was flushed prior but with the condition during trade in I doubt it. Fluid was dark with a hint of red, no smell. Anyway, I finally decided to do a flush but only at the dealership. It's been a few weeks and a few thousand miles and so far no issues at all. I did debate doing a fill and drain with a filter change. One problem with that is the filter in the acadia is not changeable without taking apart the transmission. Next problem was I didn't like only 1/3 of the fluid being changed. I plan to keep this vehicle for 10-15 years or 300-400k so the fluid needs to be changed 100%. From now on i'll keep it changed every 50k.

@curiosity2314 6 лет назад

Well when it comes down to it, if you use synthetic transmission fluid; add if you can a spin on filter; a drain; and change it with your oil you should be fine for a very long time to come. Manufactures make it seem like you can wait but do not wait, Being clutches wear there is going to be more than "Hydraulic" fluid running through the lines. The stock filter is not near enough to keep a transmission clean. If you start changing clean; you will have an idea as to whether it was manufacturing or your fault. Morale of the story, change the oil and filter as often as you can; clutch packs have a certain longevity but they will last much longer with filtered oil.

@timtitus6846 5 лет назад

Should have checked the fluid level earlier at the high level plug. PS - the Verano doesn't have a trans filter!? OBTW - the gap on the spark plugs was too tight/close from the factory! Gee wizz!

Not all black ATF is the same. Just because the ATF is black is does not mean that is has turned into a gummy varnish or has burnt clutch material. If the ATF is black and smells normal then drain a couple of quarts and replace with new ATF should always be a safe bet. * Black oil in the crankcase does not mean your engine is bad just like black ATF does not mean your transmission is bad.

My 03 Avalon has 310K miles on it. At about 305K, the transmission fluid was mild dark and had a little bit of a smell, and in driving it felt like there was a lot of slip. I had a pan drop service, and the mechanic that did it for me (because I don't have equipment to do this stuff) said that the original filter was still in there, and also that there was surprisingly no debris. The mechanic overfilled the pan when he put it back in, but the transmission runs more than fine; it still slipped a little bit just after the pan drop and filter change, but over time it settled and runs perfectly. I guess, even at 300+K Miles, this vehicle ended up being in that inbetween spot where whether a flush or pan drop should be done is unclear.
