Very clean and informative video without any frills or thrills! Perfect for getting the job done quickly and efficiently! Thank you!
I’ve never seen someone so smooth with those cooler line clips!
This is the easiest and most straight forward method I have seen. Thank you....
Thanks!
MasterJacks what if your doing it on a 6l50 Chevy Colorado but it doesn’t have a dip stick. The place where you fill it is down below where the pan is right above has a fill plug
MasterJacks hey do you have to do this when the engine is warm in order to get it to pump to the return line? I’m trying to do it on a 2018 Chevy Colorado diesel
I know your video is a lil old but thank you for sharing because it help me after I accidentally put too much trans fluid in my 2011 Silverado and I did exactly what you suggested and I was extremely grateful that it worked as well as it did…. Thank you again!!!!
Best one yet! The easiest and straightforward method. Thank you.
Great video. Was very helpful!
Thanks! 2:44 to tell the whole process, rather than 30 minutes of nonsense while doing it wrong. Well done!
Thank you, this was extremely helpful 👍
That was freaking awesome thanks!!!!
Excellent instructions and thanks for adapter info too
Great video!
GREAT VID!!!
Very Good Info !
Just did mine thanks i did exactly the same first flush like a gallon and them changed the filter installed the newer filter I add one gallon of new fluid and flush one more time and repeat the process 3 times 3 new clean fluid and 3 dirty fluid out tha thanks
If you over fill can you not syphon out through the filler tube? Thanks
Yea good and straight forward but how did you change the gasket
Got all mine tour part, I got the 397 line in and I can't get that clip back on.. doesn't want to line up.
I use Walmarts cheap super tech fluid for the first 90 percent of the flush. I then I switch to the expensive Valvoline to fill vehicle.
Is this the same process for a 06 chevy silverado 1500 5.3?
How much oil goes into my oil pan. I have an 02 Chevy avalanche z71
Tired this but no fluid came out of the line. A transmission guy told me there is a thermostat in the transmission that needs to open to allow this to flush is that true? Very confused to how you started the truck and it flushed instantly
Can you do this to a 2011 Chevy Silverado 2500hd? 6.0
I don’t feel confident doing it, yet it is well explained. Looks like that small mistake can cause trouble
Only real mistake to be made is willfully driving it when it's either too full or too empty.
Did you do a fluid change or just the fluid flush. How do I know when I need to change the filter or do I need to?
I recommend replacing the filter prior to the flush. After replacing the filter and adding fluid to the pan, you would hook into the cooler line and begin the flush service as shown in this video. th-cam.com/video/DQsRsaLwGEA/w-d-xo.html
You did a great job. on the part qye connected on the return and fitted the transparent pvc hose what is it called and where did you get it?
It's a line fitting that you can buy on Amazon. Hayden Line Fitting 397. I also have a link to it on my website. Thanks for watching!

@@MasterJacks tankyou
How much fluid are you adding as the fluid is being pumped out?
Just do your best to keep up with what's coming out. If it starts pushing air, turn off the truck and add some fluid before continuing. Too much isn't really a problem as it only can flow so fast down the fill tube. It doesn't have to be a prefect balance. When clean fluid is coming out, I like to let it get a little low (maybe pushing a few air bubbles), then I shut off the vehicle and reconnect my cooler line. I then make sure a little fluid is showing on the stick then start it and check and adjust the level as needed. It's easier to add fluid to get to the correct level than take it out.
would it be damaging to the transmission if you just drained it and then filled it while it was running? I just dont want to buy extra fluid because it seems like the new stuff is going to mix with old a little bit. meaning the color change will take longer...meaning more fluid needed to add.
Ideally this service is done after dropping the pan and replacing the filter. Then you add the 6qts to the pan, hook up your lines for the flush, and go straight into the flush. That way you never mix of old and new fluid.
Less ideal, and I'll likely be berated for this, you'd be fine to begin the flush without adding fluid, until you're pushing air, then turn off the vehicle, add 6 qts, then restart the vehicle and continue the flush until you get clean fluid out. Should only be 6 more qts. Total system capacity is 12.2 qts.
Even if you did allow them to mix from the outset, and just flushed 12qts through, your transmission would be happy, regardless of final fluid color.
Whichever method, be sure to check the final level and adjust as necessary. Hope that's helpful, thanks for watching!
Do you change the filter out first then the fluid?
Yeah, if you do the filter, fill the pan, then set up the flush before you start the engine, you end up saving the amount of fluid needed to do the flush. If you do the flush first, you end up dumping clean fluid when you drop the pan.
Would you flush the fluid first and then change the filter or vice versa?
Ideally do the filter first, fill up the pan, connect to cooler, then start the engine/begin the flush.
If you do the flush before changing the filter, you'll be dumping new/clean fluid when you drop the pan to do the filter.
How do you do this by yourself? I don't have anyone to shut the truck off when the fluid changes color while being pumped out. What would happen if once it changed color I ran around and shut it off myself?
It's definitely easier with a helper, but your idea would work too.
Question. If i pump out some fluid with the hayden line fitting 1st, does it suck the pan dry? Then you can drop the pan mess free because there no/little fluid in it?
Yeah, the pan is the initial pickup point so doing as you suggest should get most of the fluid out.
Quick question start by changing filter then are you saying add new fluid back into pan after filter been change so when pumping out old you get a full flush and not bunch of air bubbles thanks
Correct. You want to add fluid to the pan after the filter change and prior to the flush.
Cool thank again for the fast reply was a perfect video
Can you do the flush without the pan drop and wait until the fluid turns red?
Yes 👍
Hello i'm from indonesia, where can i buy that hayden line?
Thank you,

This link will take you to my website. I have a link there to the part on Amazon. It's labeled "GM Cooler Line Fitting"
My silverado is at 105k miles, I'm not sure of the servicing done in the past but I plan on checking using the vin. But with the mileage it's at I've heard a transmission flush is dangerous, is a fluid drain and fill up still an option?
Thanks for the question. I personally wouldn't hesitate to replace the filter and exchange the fluid on a transmission with 100k, especially if it's currently shifting as it should. Your chances of prolonged transmission life are better than if you leave burnt/spent fluid in it.
Explanation: A fluid exchange or "flush" simply adds new fluid to the transmission while the old fluid is being pumped out. New fluid is a good thing for your transmission. It has friction modifiers, heat resistant properties, cleaners, etc. If you have a slipping/poor shifting transmission prior to a fluid change, replacing the fluid can unmask an underlying slipping condition. Bad fluid causes internal wet clutches to wear more rapidly. The worn material from the clutches is then suspended in the fluid creating "false" friction and temporarily hiding the slipping condition. If you replace the fluid, you no longer have worn clutch material floating around. In this situation, a fluid exchange (flush) would seem to make the problem worse, but in fact, the problem was already there, you just found it by servicing your transmission.
@@MasterJacks ok thanks for the details, people normal say yes or no and give no information
Does fluid come of out of the transmission cooler line too during the flush? Did you block off the cooler line?
The fluid is pushed out the cooler and into the bucket. The return line has no flow when disconnected. You don't need to plug it.
Does the return line supply any bushings or bearings when it returns to the case or does it just dump back into the pan? I want to do this to my 89 caprice classic but it has a Thm200 r4 tranny and wanna make sure cutting off the return flow back to the tranny wont damage it.
@@jacobgensimore7346 its a return line, no it won't cause any damage.
Did you change the gasket?
Not on this service.
6L80 112k miles, trans slips and revs out in 2nd gear for a bit then goes back into gear. Happens once ina great while, rarely. Could I do a flush/exchange or will it make it worse? Or is it best to just drop the pan and refill?
I have 6l80 with 164k miles tow almost daily. Last time was longest I had gone without change 40k miles I was feeling slipping and hard shifting. I was dreading dropping the pan but I did, filter was clean, after new fluid it ran fine again.
@@greenteamlandscaping2218 Have a 2011 with 211k flawless miles on it ( except for the body rust) , tranny acting a bit off now. Was thinking of doing this myself. I've done brakes, shocks, struts, oil pressure sensor, plugs wires etc, so I'm not afraid to get my hands dirty, just never really messed with the tranny before except on an 86' Corvette. My fluid has been changed twice since new, it's due now it is very dirty.
Do you cap off the disconnected cooler line? Will fluid leak crom there as you are pumping out the old fluid from the radiator
You don't need to. There is no suction or flow on that side.
@@MasterJacks awesome last question is this the same process on a 5.3V8 with the aux transmission cooler?
Auxiliary coolers can be installed either before or after the radiator. If your auxiliary cooler ties into the line going to the bottom of the radiator, the method shown in this video will work for you. If your cooler ties into the line coming from the top of the radiator, you'll need to disconnect the line coming out of the auxiliary cooler headed to the transmission. If that's the case, your fluid will come straight out of your auxiliary cooler into a waste bucket while you add fluid through the dipstick tube. Same process as the video, different access location. Hope that helps
@@MasterJacks thanks, it's the stock aux cooler that came with the tow package. Your method worked and aside from me making a mess and getting a lot of atf allover the place it helped me out a lot.
@@MasterJacks oh while flushing did you shift it in and out of gear I didn't but wanted to know if I was supposed to do that
Don't Flush, it doesn't Clean magnet or filter, just change filter and fluid. I changed my Transmission filter gasket, fluid and seal, and I was cussing engineers, another 1/2" clearance for the exhaust that is directly underneath would have made this a quick change. I tried to remove pan and it hooked on the back end and prevented removal.
So I removed the Transmission filter which took some maneuvering and thought that would help, it didn't. I do things right and had to remove pan, to clean and change the Seal as well. HERE IS HOW I DID IT! I had the pan loose and rotated it towards the curved front end of the pan and it cleared! I was underneath looking up, I think it was a clockwise action, but you will only be able to do it one way. I cleaned a bunch of fine clutch wear (113k) off magnet and reused the gasket and then removed the seal by using the shiny chamfered area around it by using my small ball peen, and a screwdriver size forked end small nail puller, collapsed it and pulled it out with needle nose pliers. It was very stiff and old and may have lasted, but I doubt it. I then took a deep well socket, as I remember it was a 22 mm, (whatever fit the exact collar on the seal), and tapped lightly and patiently until it fully seated and tapped it once more for good measure. As far as the Pan installation, I already had the Transmission filter and seal installed, and they say don't put anything on the reusable gasket and because it was not flexible, has raised ribs and had crush type bolt holes, it was easy. I did not have to rotate or do anything special, as I recall I put it in from the front and bolted a couple to keep it in place and used my nut driver to snug all of the bolts then just used a 1/4" drive socket and extension and used my 3 finger tightening method in a tire lug type sequence. It shifts better and smoother! And these 4L60E and 4l80e transmissions are subpar anyway, I have changed a few on different Chevy trucks over the years.
This is for my 2011 4x4 Avalanche truck. Good Luck!
Thanks for sharing your experience. I wish I had known that when I did this one. I had to get creative to clean the pan and magnet. th-cam.com/video/DQsRsaLwGEA/w-d-xo.html
Nothing you present is actual fact. A fluid “flush” involves chemicals and IS NOT recommended. A fluid “exchange” as presented in this video is the accepted practice in industry and is completely safe for a transmission in good working condition. You are replacing the friction modifiers and other worn out additives in the fluid. The only thing that isn’t recommended is leaving the old filter in place. ALWAYS change the filter with a AC DELCO unit. And don’t get caught up in baseless old wives tales.
Do you NOT need to go through the gears to flush the TC when running ?
Not for the toque converter, but shifting will help push clean fluid through the valve body to individual gear circuits
@@MasterJacks
Thanks for the quick response,
I've watched like 50 different videos on this, I just bought a 14 silverado with the 6L80. I am going to do a pan drop, filter swap and flush like you did. I was just curious how much old is still in there or is it miniscule. I was just wondering if I need to do another drain and flush in a month or so the get closer to 100% new fluid?
@@tomwoods8678 If you do this procedure and don't shift it through the gears, you're going to get 99% of the fluid. No stress.
@@MasterJacks
Great, thank you so much. Nobody says that in all these videos. I can definitely live with that without doing another one until 50k get put on it.
Excellent video and info. I have paid a shop to exchange my trans fluid twice for about $170 each time...and that was decent price compared to dealers. Planning on picking up that fitting and doing it myself from now on. The last time they did not do it this way as then did the first time at the shop...but rather used some machine that both drew fluid out and added it back using the fill tube. I was not convinced it was as good as the previous method of disconnecting the return line. Maybe I missed it, but is this done with it in drive by a helper or what?
Thanks for the feedback! I usually do have someone help me with their foot on the brake, cycling it through the different gear positions. It's also nice to be able to tell them to turn the vehicle on or off if I need to stop the procedure for some reason (get a new bottle of fluid, change buckets, etc).
Ooh, there's a familiar face :P Time to change my trans fluid as well... this video was great
No way for a full flush. That was for a partial flush for sure!!!
How much fluid did you roughly need? And this is a 4l60e, correct?
This is a 6L80, but the cooler connection and process is the same. I usually buy about 4gal and try to stop the flush with enough left to adjust fluid level if needed. You'll also use less fluid if you do a filter first, fill the pan, then go straight into the flush. The filter is where the suction starts, so with new fluid in the pan, you get a clean "push" through the rest of the circuit. Thanks for watching!
@@MasterJacks okay, thanks. Ive been looking for a good video for months and am finally ready thanks to yours!
@@MasterJacks Dumb question maybe but does the fill tube fill the pan you cleaned and emptied first or how does it get filled? Thanks
@@josephnshelbyalongi5393yes, the dipstick tube for checking the fluid level is also the place you add fluid to the transmission.
@@MasterJacks yea i kinda knew that. like i said not thinking. first of all thx for such fast response. you have a new sub but also how much fluid would you recommend buying using the same method for the 6l90 I have? 6.5qt in pan and 13 total qt.system which Im sure you already knew. :-) thx again.
I went to order the hayden fitting and it said it would not fit a 2010 1500 is Amazon wrong
Ya, I don't think that's right. It should fit your pickup
@@MasterJacks thank you
Amazon is wrong I picked mins up from advanced auto parts
I was told never to change it my truck is at 140k. Bought it used with like 110k! Was told never to change it would cause it to start slipping
Myth
Did you ever changed it ?
Sadly, this method did not work for me. I only got about 2-3qts until just bubbles(out of a 12qt system) so it accomplished very little.
Make sure to watch the video in it's entirety. You'll have to add fluid to the pan while it's being circulated out in order to "push" all the old fluid out of the system. Once the pan is empty (2-3qts), if you're not adding fluid, the pump will cavitate with air and no longer circulate fluid. Adding new fluid is meant to take place simultaneously with the discharge of the old fluid until it's coming out as clean as it's going in. Hope that helps, good luck!
Around 50 seconds you say 3/8 inside diameter tubing but the video says 3/8 outside diameter
You'll need 3/8 I.D. tubing
Drop the pan ! Change the filter !

Bought that harden 397 and it is much smaller than the factory Line. ???
What engine and transmission do you have?
@@MasterJacks 2018 1500 5.3 2x4 with the six speed.
I’m wondering if they packaged it incorrectly. The box says 397 but it looks smaller than the one you show in this tutorial. Could yours be incorrect?
@@MasterJacks just realized that yours is 2011, my 18 is a different set up.
@@Mattsharona sorry it didn't end up working out. I believe that changed in 2014. Maybe you could find a cooler line for cheap at a salvage yard or online and cut it off to make your own adapter. You may also be able to unscrew the adapter fitting from the radiator, match the threads, and create your own setup from the hardware store. Baring that, there's always a dealer of last resort that could do the service. Thanks for watching, best of luck!
397 didn't fit. Was too small
That's weird. What year, make, model do you have? 1500 or 2500?
@@MasterJacks 2016 1500. The 397 was very loose in the fitting. Just a tad bit too small.
@@bkelley4443 I think in 16' they went to the 8-speed. Maybe the lines changed? 🤷♂️
@@MasterJacks i have the 6 speed. Not sure why it would be different but oh well. I have a hand pump and ill just pump out some from the dipstick and refill it a few times. Your method seems much easier though!
