4L60E Transmission Flush. NO Special Tools Needed! The fluid was REALLY bad!!

- Hey everyone, check out our latest video. This one is the process to do a full trans fluid flush on a 2004 GMC Yukon 4L60E. I recently did a pan drop, and the transmission fluid that came out of this was horrible! You couldn't see through it even if you held it up to the sun.
This is how I did it with NO extra parts to purchase. It was all done with stuff I had laying around the house. This process would work for a Chevy Tahoe, GMC Yukon, Chevy Suburban, Cadillac Escalade and any other 4L60E powered car. It made a HUGE difference, and should be something you do in your car too!

This has to be the cleanest flush method I have seen on YT! Well done sir. IMO the flush method is the only way to really get all the fluid exchanged in the system. Subbed! TY
Thanks for watching!
Thank you ...owe you a cold beer!!!!
Good information, thanks. 👍👍
this is my first video we have seen, thank you sir we like your video 😁😁👍👍
Thanks!
I'm also gonna get a fitting with barbs on one side and the same thread as the radiator side so I don't need to mess with the fitting clip....
the RAD iator is RAD 😎 This helped me tackle my silverado, thanks!
Glad it helped you out!
👍👍👍👍🔥🔥🔥. So much useful info. I commend you for this s video, cause I wanted a flush those machines may cause damage to occur in other parts of the engine.
Thanks again!!😊
Thanks for watching!
Thanks man...I am about to do mine as it's sluggish already.
Glad it helped you
Did it helpV
my son and I change the Tranny Fluid every spring, before we start pulling heavy trailers, he has a Nissan Ultima CVT tranny, and has that changed annually also, it has 125,000 miles and runs like new. His truck is a 2006 RAM TurboDiesel auto Tranny, changes fluid for every long trip, pulling 20k loads, never a problem with it
Basic maintenance goes a LONG way
CVT are a time.bomb, especially from Nissan
This was what I needed to remove the line!
great video. OK- i have an 05 suburban- same set up. if i can't get fluid 'out' (don't want to drop the pan, etc.), should i unhook the bottom line too - for it to drop fluid out?
Curious to know what you did as your question is 3 months old, but that's what I've heard guys do. Just pump all the okd fluid out until you get clean fluid pumping out.
if you use biger hose diameter, you can screw hose into radiator hole ( thread)..u save time with mounting hose to nut....
Absolutely. This hose is what I had laying around the house so i made it work with that, but you could use a bigger diameter hose as well.
The return line lubricates the transmission. It doesn't dump into the pan, so you were doing damage, which is not smart.
Do you need a two chamber pressure vessel or something to pump new fluid into the return then?
@@stevetillery2432 Pretty sure the flush machine will use the return line and not the dipstick - they have the choice at the quick lube place to use the dipstick or both cooler lines (one to flow out and one to flow in). But the problem with using the return line for the new fluid is I think that will force out the old fluid blockages back through the transmission to cycle back out as the new fluid replaced the old.
Thanks for the video first of all!!!!
So I’m a little confused. I understand using a vacuum to pull fluid from the dip stick. But wouldn’t you want to change the filter afterwards if you got the full flush complete you still could vacuum the pan out and put that fluid back in?
Yep, you would want to replace the filter as well to complete the service. I had already replaced the filter so I didn't do that in this video. Thanks for watching!
This is a cleaner way of doing it.Once you loosen the trans pan, you get fluid all over. If you extract fluid first, cleaner job. Also, some change the filter every 2 or so flushes, some people open a whole new can of worms by taking the pan off in the first place.
Especially w/ an '06 Yukon it can be a pain just to get to the bolts & that's assuming the bolts aren't rusted in ace. A shop posted a video & spent over 2 hours cleaning off the old gasket & mating surfaces. I've heard from multiple sources the filter isn't much of a filter as it's a sealed system, & the magnet is what collects the particles not the filter.
I haven't changed the filter in my '00 jeep cherokee XJ AW4 trans & a lot of guys don't & we get 300k or more on those old but rugged engine & trans. Using a quality fluid & regular "severe use" service schedule seems to be key. Adding a trans cooler would also be a better use of time & money then scraping gaskets & getting the pan to seal.
Thank you for making this video I have water mixing in with the transmission oil and I need to flush it out I believe radiator inner cooler busted and is causing water to go in the oil cooler causing it to mix with the transmission oil
Good luck, hopefully it was only a little and for a short time cause water in the fluid will kill those clutches quick fast and in a hurry
Hey how did your tranny work out were u able to save it? I've got the same problem
So, to be clear - After pan drop and filter change, bring fluid to correct level and THEN add 1.5 gallon ATF before flush begins? No problem with overfilling? Thanks.
for short durations (such as purging/flushing/whatever) no, not really any issues. you just don't want to run it overfilled during normal use.
Great method! Do you happen to know where's the line located in a Kia óptima 2008? To be honest I can't locate it
Thanks. Not really sure on the Kia though
Question, did you begin putting in new fluid as you flushed out old fluid? Or did you first flush out ALL old fluid?
I dropped the pan and replaced the filter before filling it back up. Then once that was done I performed the 'flush' so clean fluid was being pumped through the trans.
How's much bad fluid can you take out at a time before running it too low?
I did it a gallon at a time. Had some fluid in it, added a gallon, pumped a gallon out, rinse repeat.
After dropping the pan, did you fill with fluid before you drained through the radiator? if you did, I missed that part.
Yep that was done before I started making the video. The pan was dropped, the filter replaced and clean fluid re-added
Quick question..was this the first time ever changing the fluid on the Yukon..if so how many miles was on it. I have a 2004 Suburban that I bought used..dont think the trans fluid has been changed..just hit 100K. Some mechanics say leave the fluid alone..some say to change it.. Thanks
Honestly, I don't know cause I bought the truck used with 145k. For the mechanics that say don't change it....... I say they are in the wrong. Doing a pan drop and filter change would be a good start then after a couple thousand miles do this method to do a full fluid exchange. NEVER do a machine flush.
@@JrZCarZ Thank you for the quick reply and advise!!. Im first gonna do a pan drop and fluid change, I will replace the pan with one that has a drain plug so its easier when I change fluid again after couple thousand miles.
I’ve heard that also. But all fluids NEED to be changed. If you’re having problems,they say you can screw it up more. If you’re Not having issues with trans, change it by all means to keep it problem free for as long as possible
I too have learned that you should change the fluid. Only from now on I'm gonna have the pan dropped ant a look at the filters. They are there for a reason and I've heard the arguments for leaving it alone but really that just means you will drive it until the transmission grenades itself. Now I was in that camp practically my whole life but having done a couple of older projects and now I'm replacing my transmission as I speak. Why ? Because I ignored some basic things it started doing; which was over modulating or slipping going into third. Now I'm armpit deep in grease and still only halfway done. The point is there are good arguments for both but having lived long enough I would say preventative maintenance is you best bet.
Did you empty it first or replace it as you were removing it? you mentioned 2 and a half gallons used
I emptied it first and did a filter change. 👍
Does this only pertain to vehicles without a individual / separate radiator cooler?
Fairly much. But the trans lines may meet the rad in a different place
I thought you were giving up on the Yukon, glad you haven’t.
Thanks James, I was going to write it off but I'm stubborn after I have time to think 😁. I just took it on another spin for about 5 miles and it feels better than it did yesterday.
@@JrZCarZ Great, new Yukon’s are selling at $78k, unbelievable, Escalades close to $100K. We had a Lexus ES 300 with 200K, we flushed the transmission 3 times and ran compressed air through the trans cooler to clear out any sludge and blockage, it then ran smooth as silk.
So far I've put about 35 miles on it and no issues! Which is good, because the starter crapped out on the Torrent and I'm not going to pay the 'bend you over and ram it in dry' box store prices for a starter. RockAuto it is!
@@jamespnhow many miles did the 300 last for?
@@KollynJ It was sold after we processed the mechanic’s lien.
Be careful. My 2003 Escalade fluid return radiator outlet is on the bottom, not the top one as shown here. Made a mess!
That fluid looked trashed! This is a simple way of flushing the fluid out
How did you keep fluid going In to the trans?
Basically I added about 1.5 gallons into the dipstick tube, then.pump out 1 gallon. Add another gallon, pump out a gallon and it should be clean by then. That way you know there's always fluid in the pan and it won't run dry.
What’s the best way to do it so I can drop the pan without making a mess? 2003 Yukon 4l60e
If you suction the fluid through the fill tube it will get enough fluid out to where it's not going to make a complete mess when you drop the pan.
Any updates or feedback on how the transmission was after the flush, any noticeable difference in how it shifted, no change? Thx
Transmission was good for a bit after the flush but it ultimately suffered the common 4l60e failure.
@@JrZCarZlol I might be in the same spot. In the process of doing 2nd drain and flush and wondering if it’ll last longer or less time after swapping out another 5qt of clutch material filled pinkish black atf. how many miles did it last?
@JrZCarZ Sorry, I'm not familiar with the "common 4160E failure" what is that failure?
Here's a good read on the issues
gearstar.com/3-symptoms-of-a-failing-4l60e-transmission-and-how-to-diagnose-the-problems
Maybe I missed this, but did you use Dextron lll fluid? Is Dextron vl OK for my 2004 Silverado? Seems to be different opinions on this.
I used a multi vehicle fluid that was Dextron VI compliant. Some are not so you have to look at the bottle to see.
Dextron VI is what I've read is called "backwards engineered" meaning it can be used in older transmissions that used dextron III. Gm went to dextron VI in 06. I use it in my 05 and 06 sierra, my 03 yukon xl and my 99 Silverado plus my jeep that has a 2000 ls swap. So far so good
Was your transmission feeling like it was dragging from a stop before you changed fluid!?
Nope, no drag
Not the best representation. Others fill 2 quarts over, run it till they get 2 quarts, put 2 more in and do it again. repeat till it runs clean fluid. That way when youre done, you are at least close to proper fill and you never risk running the clutches and pump dry.
Apparently, he added fluid first before pumping old fluid out so he wouldn’t run it dry.
Hush
That was my concern as well….. if you do this, is 2 qts like the max you want to run out before topping off? I have a 2003 yukon 4wd 4L60E. Not sure the capacity range of fluid when looking at the cross hatched portion on the dipstick when hot
What size tube did you use
I believe it was a 3/8" tube I used for this
What about what's still in the Trans cooler??
Hi there, Some people states that flushing your trasmission after 150k is not good at all since it would force all the metal debries in the toque converter run into the valve body then causing sleepage. Unless it is just a falacy? What do you think?
Hooking up a transmission to a service pump like they have in dealerships for a flush is not good. If you do it this way you are using the transmission pump to do the fluid pumping, which is it's normal operation, so it's easier on the trans and doesn't force the fluid through. Take it with a grain of salt thigh cause if you ask 10 people the same question you'll most likely get 10 different answers 😄
Again. I asked 10 trasmission tech senior experts and told me depending of the fluid inteeval service in your trasmission would take the right option to flush under normal drving conditions , but if the car's owner doesn't know or doesn't have any previous récords of maintenance the probability could be 60% to 40 that after any good procedure flush would cause a slippage after several miles of driving your car. Now the grain of salt will turn eventually into a headache.
@@hansenriquerach-mendoza3515 I think the flush machines either go through the dipstick (which is no different than what someone could do at home with a dipstick pump) OR they hook up both the flow out and flow in to the coolant lines! By flowing the new fluid back in through the cooler line then they are forcing the gunk backwards out of the transmission because the new ATF is flowing right back into the transmission into of if the new ATF is going down to the pan directly via the dipstick. Pretty sure that is what is meant by "reverse flow" via the machine flush.
HOW MUCH YOU DRAIN OUT BEFORE FROM THE PAN?
I drained the whole pan cleaned it and put in a new filter
so you empty a gallon then stop, add a galllon and repeat until it's clear?
Yep. I would add 1.5 gallons in before you start so when you empty the one gallon out you're not going to run the trans dry of fluid. Then when you get good clean fluid out, fill as per the dipstick.
@@JrZCarZ thank you man! Yeah understood on the first cycle / gallon since I may or may not empty/drop the pan...but I really should.
@@vzangla if it's been a while, I'd suggest a pan drop and filter change.
@@JrZCarZ I
Well that’s the plan, to get all clean fluid in your trans
Why the hell did gm start using those clips? I don’t know how many I’ve lost doing engine swaps. And then hoping you can find new ones at the local dealer or parts store.
It's not just GM who has those clips for cooler lines. Pretty much most manufacturers use them.
Air Raid!
THEY SAY YOU ARENT SUPPOSED TO DO A FLUSH ON VEHICLES? WHO IS RIGHT?
i JUST DID IT ON MY TRUCK, SO NOW IM WORRIED LOL
Having a machine flush pushing the fluid through the trans isn't good, however using the trans pump to pump the fluid is perfectly fine.
I sent a sample of my trans fluid to a lab to see what condition the transmission was in before I did a substantial drain and fill. The lab is Blackstone Laboratories. My >100k miles transmission was in excellent shape according to what they DID NOT find in the old fluid.
I've used Blackstone in the past sending out engine oil. It's a great tool to have in order to see how things are going with your car
I’ve always done them on my vehicles. Honda,Tahoe,Sable,no issues. But sooner or later you do want to get in there and swap the filter also
anyone hear the sirens in the background
I live about 1000ft from a fire station and 1/8 of a mile from an EMS station, so I hear sirens all the time 😄
I was told bye Ford not to do it I didn't know the history of car got 204 thousands miles on it seal transmission
2009 Ford fusion. No flush transmission
So really don't know now what to do.?
I quess nothing ... History unknown.?!
I would just do a pan drop, then drive for a couple thousand miles with some new fluid and do that like 2 or 3 times if you are unsure of the history. I have another video on my channel on changing the trans fluid on my 2013 Escape that may help you out.
I don't know what you say and what you do,😊😊😊
Really people for how long it took him just to get that off. You could have already dropped the transmission Pan. You want to clean the pan anyways Stop being lazy and do it The right way does not mean you have to change your filter
You obviously didn't watch the whole video. I said I already dropped the pan and replaced the filter. Dropping the pan only gets about 5 quarts out of a 13 quart system because of fluid caught in the cooler, lines, valve body and torque converter. This cleans that all out. Thanks for the comment, but you might want to try to understand things before trolling 😄
This part is needed for a full flush. Fluid still in the cooler and lines.
