- What’s going on CZcams!!! I plan on doing many mods to my 2010 GMC Sierra SLT 5.3 and hope you guys follow to see the progress!!! Check out how to Disable the AFM for free!!! This will save me some money for now haha. I still plan on purchasing a tuner but for now this shall do!!! Let me know your thoughts and if I’m doing this right!!! Also, another reason for the horrendous MPG you saw in the video is because I’m usually working out the truck and always have it running to keep the AC on...it has been a hot summer so far in New England!
HOW TO DISABLE AFM: Enter your truck to manual mode, select a gear up until 5th gear or shift as you drive. The truck will never leave V8 Mode. I haven’t tested yet but at 6th gear the truck will activate AFM.

I’ve been doing this with my truck for a long time I have not had any issues afm is horrible especially pulling a trailer it seems to come on at the worst of times even while cruising around cities or towns it’s just robs your truck of power when you want it most
Just get the Range Technologies obd plug in , stick it in D and have all speeds available. Did this years ago on my 2011. The average owner spends thousands on all kinds of truck stuff, all of a sudden an RT module is way too expensive.....
My thought exactly I put it on around 140k miles about to hit 200k still runs good
@@miket2172 did you have to adjust the oil level or plug the pressure release valve in the oil plan?
I have a 15 4.3 and the smoothness from having the afm off alone is amazing plus the power and delaying of an expensive ass repair… i can go 65 just above 2k rpms in 5th
Big Facts Got 250,000 miles No AFM problems Truck fly like a Turbo Jet
Some people got lucky. The big facts are this - the AFM system is a bad design and most owners end up with oil consumption,stuck lifters and ruined camshaft. If it was always reliable there wouldn't be any efforts at getting a class action lawsuit. Some of the well known engine reman companies delete the system as part of their remanufacturing process - with good reason!
What did you do to avoid it?
Mine has 230k miles on it and the afm still works fine. Never tampered with. Good oil and early changes. Can’t even feel when it transitions between v8 and v4. No problems using it how it was designed. At this mileage when it dies it dies.😊
Nice
My 2012 silverado has 147k miles
I've seen them with 300k and I asked if they deleted the AFM guy looked at me puzzled and asked whats AFM lol ... They don't all fail
I think this is more of a testament to your foot to gas pedal ratio being way better than most people.
Apparently the way you drive is perfect for the way it was built
another factor that matter is maintenance. oil changes every 3k. trans pan drop and fill or flush every 25-50km. almost everything basics maintenance matters for these trucks
Just plug a trailer plug into the trailer port. That disables it.
I find this hard to believe
So do I.
No it doesn’t , no load is no load.
Just picked up a 2011 gmc 1500 z71 all terrain 78k one owner
And was nervous about afm
Amen for videos like this
About to get the same truck 85k miles, how is yours holding up?
Update please any fatigue on the transmission?
*There was a class action suit against GM for lifter failure because of AFM. Honda calls it VCM and THEY had a class action against them as well for similar failures.*
*Thank you for sharing this. I was going to buy the $300 disabling tool.*
😊😊
😊😊😊😊
We bought a used 09 Accord from a private seller. Great car but had VCM misfires. Installed a 100.00 VCM muzzler and is now a full time 6 unless it's really hot out. Honda mainly got sued for excessive oil consumption. 15 years and all these car companies still haven't perfected this idea.🙄
The AFM system isn’t just fuel injector shutting down and valves disables it also includes the transmission slipping to prevent harsh jerk when the AFM goes from 4 to 8, I had valves start rattling. Did research , got QCR AFM eliminator, big difference , more power With faster crisper shifts and no change in mpg at all. I have heard if you have valve rattle there is serious problem and you are near to engin3 or tranny damage.
Do you have the link for the one you used?
I've had over 20 if these never knew thats why they jerk lol
I watched this video last week and tried it on my 2011 Suburban with 5.3 and 6spd trans. I can say it has worked perfectly.
Update please any fatigue on the transmission?
No issues at all, even on the highway. Why would you think the trans would get fatigued? It's not doing anything it's not designed to do. This mode of usage is even described in the original owners manual. The fuel mileage has not changed either - my Suburban has always averaged 15 mpg and still gets that driving in M5 mode constantly.
Would it be better to be in M5 than M6? My gmc Sierra 2010 can go up to M6
@@DGG-xw1wj M6 allows the AFM system to be active, M5 does not allow it to be active. That's the point - to turn off or disable the AFM.
I have to try this in the "5" mode. I saw another video and it showed to go up to the highest gear which is "6" for mine which is where I tried it. It worked fine but I wonder it it'll be better in L5. Thanks for clearing this up.
This works for 6 speed trucks but 2007-2008 models still had the old 4 speed 4L60 from the previous GMT800. Driving around in 3rd is fine when towing the camper and it doesn’t do afm, but that’s hardly a good idea under normal driving conditions. I’m buying a Range disabler soon.
Same just had my second "engine skipping". Had it rebuilt last year. 1 year later I realized I should have just bought the range disabler
The problem with the AFM system is the Regular flow Oil Pump. Three years ago I replaced with Melling High Volume Oil Pump..... No ticks, no nothing....Pressure is at 40 at Idle and just a little above 40 while driving. Still burns/consume oil until I make other changes.... 17.5 mpg combined, 22 mpg on highway
I think it works in "trailer mode" also. While driving in "D" under a very slight acceleration I can feel a high frequency vibration, which I believe is the AFM being active. I tried the manual mode and the vibration goes away. But when I use the trailering mode not only do I not feel the vibration but the acceleration is a lot better. Uses more gas, yes. But sometimes I like the performance better.
Don’t disable just because it feels weird. Disable it because it is a matter of time before it fails and collapses a lifter and the dealership tells you that you need a new engine. The GM DOD/AFM design was made only for a new engine.
I have a lifted 2014 Silverado, the additional weight from the tires, rims and 7" lift kit has definitely sucked up some of my power. If you push your trailer button to stop over drive you have to push again and hold for 5 secs which deletes the automatic grade braking feature and of course you can also drive in Manual mode and select the highest gear you want. Way cheaper for me to do this instead of changing rear diff gearing.
140k miles on my 2011 tahoe I always drive in 5th because 6th is to low of an rpm for my liking. I never use 6th. Even doin 90mph on the highway. It makes cruise control smoother and my highway mpg are far better because the 4-8 on cruise kept speeding up and slowing down. Side note my old 97 k2500 and 2001 sierra 1500 I always drove in 3rd. I never used OD the whole life of those trucks either.
Man this is a crazy comment for me I have a 01 gmc and a 12 and I was curious about both if driving in 3rd would hurt the 01. And now with my new to me 12 if driving in 5th would hurt it. Good to know it’s okay
@@Johnny-jr2lq oh yeah had 270k miles on my 1500 all in 3rd only changed the fluid once never rebuilt the trans. Sold it and regret it. The k2500 got a Cummins and nv4500 in it 10 years ago lol so it’s not part of the conversation
I believe 2007 and 2008 had the old 4 speed transmissions, there is no Manual Mode for those years. 2009 was the first year for the 6 speed with a "M"
Hi. I had a 08 with the four speed. Select 3 for the tranny and leave it. The DOD/AFM will not engage. Downside,lose overdrive,but I dont care as i am mostly around town driver. Might lose some efficiency,about 5 to 7%,no big loss, I can live with that rather than replacing lifters once a month.
@@capesquirtyou think this’ll hurt the trans in anyway ? I just need to do this until I can my hands on a afm disabler and possibly full delete down the rd
Thank you. I just bought a '09 Sierra and been trying to figure out how to do this without the $250 chip.
Update please any fatigue on the transmission?
I can go 75 mph in m5 mode on the highway at 3500 rpms .
I have a 2010 gmc sierra denali. . It's a 6.2 and I wanna tell you that if you think your mpg was bad that day. Mines 12.3 everyday. I used to get 13, and still can on the freeway, but I installed the power chip, and that lag is non-existent. I didn't try your method but it sounds legit.
I keep my 2012 Silverado in M5 all the time unless I get on the highway. It's much more responsive, especially around town stopping and starting all the time. I shift to M6 at 60 mph and downshift back to M5 below 50mph.
Best way to drive these trucks!
Just depend how much time you spend driving above 50 mph. If most of your mileage is above 50, your likely to have the same engine problems with the 5.4 L V8. If most of your driving is city, following your procedure will probably save your engine.
No your not.. it's no doffrent then manually putting truck in 5th healing a camper at 70mph. It'd basically tow mode.. not going to damage anything
Update please any fatigue on the transmission?
Wish I would have found this vid sooner but oh well it is what it is! Trying it out on my 2012 Avalanche so will keep you informed if this works or not!
Definitely works! Under 60 keep it at 5. Over 60 change it to 6.
Update please any fatigue on the transmission?
Those 2010 Sierra's are great looking trucks. How many miles on yours? Is it for sale? What was GM thinking? What a horrible idea this AFM is. We don't buy full size pickups for their gas mileage nor do we biy V8 engines to get V4 power.
I get 22mpg doing 65mph on the highway with dod. At 68mph no dod, 18mpg. Gas saved pays for oilchange every 3,000 miles.
I rather buy range disabler don’t you think even if you change your oil every 3-4K miles
The money youre spending in extra gas can buy you the actual afm delete.
The actual delete requires a camshaft replacement which everyone forgets about. So no it’s probably not. Only rational solution is afm disabler for obd or don’t buy a gmc
I have 2012 2500hd 6.0l sierra and it does not even say anywhere, now im concerned that ive been driving it on v4 all the time since i was complaining about a lack of power for a looong time
Not in V8 mode when your truck is in park or neutral, that's why you need a disable or tuner and delete. One of the 8 little screens or one of the several oil screens gets a touch plugged and wham one of your lifters unlocks and jams down. It's just a bad system, especially for city driven trucks that don't get their oil changes religiously and well before the "oil life" meter runs down, worse for the people that just take their vehicle to an oil change place because those yahoos aren't paying any attention to whether or not their's any particulates coming out of your drained oil.
This only works for trucks that have a 6l80e transmission if your truck has a 4l60e it won't have manual mode.
i was just going to ask that.
With my 2008 Tahoe selecting 3 on the tranny column shift and leaving it there,disables the dod,afm, cylinder de-activation,what ever you wanna call it. Pain in the !#$. But lose overdrive. Left in 3 for the transmission it will not de-activate half of your engine.. I even leave it in 3 on my short highway trips. Revs about 2900 rpms at 50.
6.0 7l70 trans too? avalanche no manual option besides man shifting
Same here I don't have M mode on my suburban 2010 4x4. Right after D it has 321 I shift the gear up and a "__" line comes under the 1 I move it to 3 and it goes thru my shifts like nothing really smooth and AFM doesn't kick in.
@@josegallo1190how’s everything holding up now ? I’m going to try this tomorrow
What’s the difference if you just put it in M6 just in case you hop on the highway and forget to take it out of M5. What difference would it make in the city? Or does it get into 6th gear just driving in town?
Read somewhere to try disconnect the oil pressure sensor and keeps truck running normal..
Just get the Range AFM disabler for $200 then its in v8 in all gears.
200?? dudes here in canada are selling it for 450......

Hey man just a heads up, the 2007 does not have the gear selector button on the stalk. I had a 07 tahoe.
so the vibration i am getting in my truck 2011 silverado is not the motor it is the torque converter all this time i thought it was my motor going bad
Hi i have the same truck how it was the sound of vibration? And how ofthen?
Or buy a HP Tuner and just click disable and disable the slip for dod in the transmission settings. While you’re at it, you can disable the virtual flex fuel that never reads right and fails to report data accurately or quickly. The infamous fuel content runaway ethanol reading causing the vehicle to run so rich you can barely start it and it drives like shit. You reset your fuel composition and it runs great for a little bit and then goes out of control in a positive feed back loop. Disable it and gone for ever. Then if the infamous lifter failure ever hits as the lifters crap design makes them a big failure point even with DOD disabled. You can do the physical delete. Also, the hp tuner route gives you freedom to adjust and tweak whatever and you can gather date and use the system like a scan tool. Check and monitor any thing you want. Disable certain codes from tripping if you want or if you have modified a system and don’t want sensors reporting a failed component that you removed.
I doubt this disables it. I'm sure you still gotta delete it all internally and change the lifters etc.
Very cool! Thank you. I have a 2012 and will give that a try.
I love Chevy and GM too I got a 2017 Silverado Swift transmission problems right now the truck doesn't even have 60 miles on it
My old 08 z71 new off lot. I ordered edge had it mounted on dash early evolution. Hopefully I'll be picking up 07 max soon I plan to use edge ct3. Not race truck it's daily. My 03 rcsb 4.8 get a snail or screw be the toy the max can tow if need be
So, this is good for city driving, but highway speeds this wont work correct? He mentioned it works up to about 50-60mph.
I have an 08 and don't have this option. Unfortunately it's because mine has the 4L60...
Had that junk in my 2012 avalanche. Crap bent a lifting rod. Took it for warranty. Chevy fixed it and the mechanic told me he could deactivate the afm. No brained for me. Never had another problem. Whose fumbass idea was it to invent a thinking engine that shuts down two cylinders at sixty mph and then expect everything two stay timed? After thirty five years of buying chevys, I now drive Nissan trucks. Besides, chevys have become to expensive.
Obama's
Most Chevy dealerships refuse to deactivate the AFM or tell customers that it can't be done. If you have any warranty left, GM will void your warranty if AFM is deactivated by reprogramming. The RANGE TECHNOLOGIES is perfect, because you just unplug it to return your truck's operation to factory settings if you take it in for warranty or if you need to have a "drive clean" test performed.
@@marcmo7138 lmao fr?
Guys...I apologize if this is a stupid question...my truck shows I can go up to 6....is that any better as far as driving say on the highway or is this in general no recommended in any setting
Does doing that change the shift points? I want this disabled because I have 46K miles and have had to change plugs twice @ $388 at the dealer. Certain plugs were oil fouled. Also drinks oil, 2 quarts between oil changes! Using the little bit extra fuel is cheaper in the long run! BTW I have a 2013 GMC Sierra. Love the truck but hate having to pay the cash because they f’d up with that stupid system!
Thank you for this video!
Such Lowes miles. How it's holding up?
Watch the AFM and Oil consumption youtube videos from Crazed Performance Repair
@@gawpaw1955
Will do that! Thanks!
BTW just had an oil change. Noted they charged me for 7 quarts. I’m old school and thought a 327 (I don’t do liters) took 5 quarts of oil. Did I get ripped?
Tried this on my 2017 Z71. Didn't work.
I had a 2000 5.3 SIERRA that advertised 285 HP, and it had 3:73 To 1 rear gears and a five speed auto.
Now I have a 2012 5.3 SIERRA that advertises 325 HP with 4:10 to 1 rear gears and a six speed auto.
My old 2000 is faster and stronger. My best friend bought that truck from me.
The 2000 was a much better truck
I just bought last fall an AFM disabler from range finder. Price was 220.00.
Just send your ECU off for $50 and have AFM option turned off. Then do a AFM delete before the AFM lifters destroy your cam and then your engine. It's not a matter of "If" it's a matter of "When"
Agreed. 07 silverado with the lm7. Just dropped a lifter in it at 175k miles. Doing the delete with a spicy cam soon
Where do I send it off too?

@@nickblackwell920 Any chevy tuner can do it. Look for a local speed shop where you can just take it and have it turned off.
Thanks for the video. Did you noticed any out of the ordinary activity from your transmission when driving in M mode?
Nothing at all!
But by limiting the transmission to 5th gear, the engine is turning several hundred rpm faster than it would in 6th gear at highway speeds.
Doesn't work on my 2018 Sierra...still shifts to v4 in manual mode.
Works on my 18 silverado never have seen it shift to v4 as long as I'm in m5
Wrong only 2009-2013 those are 6 speed can turn into manual the older models have a 4l60 no manual mode
I got a 07 and i can't put mine in m5 my dash days d 123 i dont have a m or a l
I wonder if it will work on my colorado 🤔
If you put it in tow mode, that disables afm also
Yes but that also changes your shift points and shifts get harder.
Thx man ! I'll try this on my 2009 silverado z71.
I dont think the 09 silverado has the AFM system🤔
Well my truck does
My 09 has that pos afm just did the delete kit
Update please any fatigue on the transmission?
So you preset it to 5 th gear before you take off? Do you have to downshift when you’re coming to stop?
You don't have to do anything while driving. Simply set to M5 at the beginning and forget about it. The trans works completely normal but as 5 speed instead of six. You do have to choose M5 at the beginning of each trip because putting it in park resets every time.
Silly question.. if you do this , then say you need to reverse do you need to do this again once you need to go forward again?
On my 2010 Suburban yes I have to do it all over again
I have a 2008 GMC Sierra 1500 5.3 but my display shows 3 2 1 after D. I don't see a M
I have a '08 Silverado Z71 4wd and it does not have manual mode
O wow, I did not know this. I thought all gm/chevy trucks of our gen came with manual mode.
So Has anyone figured it out
Ranger afm delete plugs into the obd port
This may have been a dream I had, but I’m pretty sure those first models that implemented the cylinder shut off had a menu option to disable it
doesn’t this damage the transmission
My GM yukon denali 2011 AFM not working, how enabling AFM to use V4?
Using AFM is what we are trying to avoid. It’s likely that whoever you bought that Yuke from already did the delete or bypass. This is good😊
Look up torque converter failures on the 6L80E transmission. Its a common failure. If you are going to continually drive in 5th then you might want to upgrade to a 6L90E torque converter. Honestly I would do the upgrade before your t/c takes out your trans
It does not stay in fifth , it is from the manufacture you can do this it will shift regular just won’t go into 6th so at freeway speeds you won’t want to do this but no it won’t hurt anything 😊

Awesome ty!
5th gear causes the rpm’s to stay in a range that the afm never reaches the set range to kick in. Save up do it right.
3:10 What tunner for 350?

How long does it last. Have you ever had any other issues. Have you had shudder issues when coming to a stop.
I have not experienced any issues. It lasts the entire drive! You just have to keep it in ‘M5’ whenever driving.
I notice it does rev a bit higher though, obviously because it doesn't shift into final gear. It does sound cool though because I have a borla attak dual exhaust and an s&b cold air intake. I learned this in the gm-trucks forum. I also learned in 6th it goes into v4 mode. I have a 2016 5.3 silverado.
Does that help with the excessive oil consumption issue that there known for?
@@adamwelker1446 The excessive oil consumption was due to the driver side valve cover not having the correct oil catch/drain hole. It was round vs the new is kinda square or rectangle. And supposedly GM corrected this problem after their 2010 models. So if you have something 2010 or older try replacing the driver side valve cover. I'd recommend getting it from your GM dealer as alot of aftermarket shops have crap replacements!

Need to wear your seat belt!
Geesh….could talk any slower and use more ummmm’s?
If you want good V8 power all the time and none of this BS then just buy a GM truck that had the 4.8 liter and forget the 5.3. GM made them from 1999 to 2013 and none of them engines ever had the AFM! The latest generation 4.8 (2010-2013) had 302 hp, the latest 5.3 has 355 hp. So if you REALLY want that extra 53 hp just do cold air intake, headers/exhaust, mild cam, tuner, and you should be pretty close! You can mod a 4.8 cheaper than deleting AFM from a 5.3!
This will cost you more gas as your rpms will stay high at high speeds due to not shifting into overdrive...
Correct. With all older vehicles even some newer vehicle, if you are looking for performance, 9 out of 10 times you are sacrificing fuel economy.
Not to mention excessive transmission wear. Leading to premature transmission failure. It’s cheaper , in the long run , to just go get it tuned out by a programmer... $300-$350 is a lot cheaper than a new or rebuilt transmission.
Around town I don't think it'll matter. Seeing your never get 6 anyway
@@alphasaiyan5760 I disagree with transmission wear because it’s not shifting as much from Afm robbing power before hills and such... I find my truck shifts half as much if I leave it in 5th cruising around town
