AFM disabler - a.co/d/1wB9YXZ

[@lawdog43494]

I purchased an AFM disabler from Range Technology. Plug it in your OBD port and issue solved. I have it plugged in for 2 years with zero issues.

[@slumy8195]

does it work for new models or certain years?

[@randog7735]

Much needed advice! Works on my 2014.

[@jcnole77]

That’s it! My man. Thank you

[@alecpalesch2664]

That’s how I limped mine to the tuner after performing a Afm/dod delete on my 2014. Almost like a brand new truck now

[@googleyoutube766]

“Hurt your gas mileage a little.” I saw yours at 16-17, mine is 21-22 with arm!

[@mikef-gi2dg]

Thanks for the info. I have had the RANGE DISABLER for 2 years this month. It works just fine, I may have lost maybe 2mpg but who cares, I like v8 mode all the time. I installed it at 70k, so hopefully I have dodged the carnage, and I get oil changed when it requests it, without fail. I would like more info on these programmers though. If I could find a way to disable the TCC lockup on my 2011 3.5 4t65e Impala, that would be awesome. Good Job on the info.

[@davidray3218]

It works for my 2015

[@Ryan-xj1vr]

This is amazing

[@smashedpapya2563]

I would really recommend just buying an AFM disabler that goes into your OBD2 port, not getting 6th gear on top of no AFM is going to seriously hurt your fuel economy

[@P61guy61]

What about for the newer 10 speeds?

[@louperez921]

I keep my 2015 Escalade on M5 and go over 100, stays in 5th. No issues at all

[@romeowhiskeylima556]

Will this work with the 10speeds?

[@SM-hy4np]

Short or quick version watch from 0:51 to 1:37......to disable V4 mode shift to L and press the gear shift selector mode button until only 5 appears to the right of the L (L5) on the screen and not 6. This will prevent the transmission from shifting up in to 6th gear as well as prevent the engine from going in to V4 fuel saving mode............Here's a thought for all of the GM rocket scientists, cut the fuel rate in to the cylinders in half on all 8 cylinders.

[@rookiechevey]

It also prevents the torque converter from locking up, in manual mode the programming shuts off lockup.

[@kyleschlee348]

My 2017 Escalade is currently in the shop engine is tore completely down 4 bent pushrod’s 4 stuck valves and 3 failed lifters because of 2 issues 1st direct injection on these engines carbons up the top end and second problem is the active fuel management or DOD failure these 2 issues have cost me 7 thousand dollars on a 80 thousand dollar suv with 40 thousand miles I did realize I was buying a ticking time bomb good luck everyone

[@mikef-gi2dg]

I hope you can get in the class action lawsuit that covers this, stick it to GM...GM...you used to be better than this.

[@darknes7800]

yeah.....but YOU could have been using GM Top Engine Cleaner every 10K miles, to keep the carbon down.

I leave mine in 4th for around town.

[@joshrides2004]

I’m just gonna say it on my 2018 6.2 silverado I actually don’t mind the v4 mode it doesn’t really change the way it drives or anything, I know the computers are flawed and this and that but when my warranty is over I’ll just pay for the tuner that gets rid of it and I keep all 8 gear Plus it doesn’t matter when I love the way the engine sounds so I’m always in it

[@michaelterry2084]

The reason behind this is to keep the lifters from failing on the 4 cylinders that shut off

[@KenMazel]

It's the added wear and thus premature failure people are trying to prevent. Ask any transmission shop.

[@BRogers776]

@@michaelterry2084 this in no way will stop lifter failure. Mine have been replaced twice on the drivers bank. The VLOM changed the second time. This was all after having an AFM disabled in the obd port for years.

"Mechanic"😂

[@gabrielabrasil1202]

I would just forget about the 6th gear 😅 the RPMs are relatively low even at high speeds

[@kennethfoley3536]

Thanks for the info. I drive a 08 Silverado with the 5.3l V8, (124,000 miles), and the AFM is really annoying. In town when slowing to a stop, the AFM seems to keep the engine in 4-cylinder mode till the vehicle is nearly stopped, which seems to cause a shuddering effect that you can hear and feel. I found that when driving in town with the gear selector in "3", the AFM doesn't come on so there's no problem. On the freeway however, I have to put the gear selector in "drive", and at 70mph and above, there is a rumbling sound that fills the cab when the AFM is on, and it goes away when the AFM switches off. At 65MPH or lower, it's fine which sucks because I like to cruise at 70-75 MPH on the freeway. I've owned the truck for two years now, and it didn't used to do this. I was thinking about getting the Range Technology module, but I was wondering if anyone else has experienced this, or have any ideas on what's going on with my truck?

[@hamm3790]

I have a 2018 Silverado. I loved him so much!!! BUT.. he has also started doing this and it seems to be a common issue with the lifters. I’m no longer in love with my truck 😢 But hoping I can get this issue fixed without having to start over with another vehicle. I wouldn’t buy the new glittery “convenient”vehicle again. I’ll take the old reliable truck next time. Way too many issues with all these new high tech/green vehicles. I’m not a fan!

My work truck 2018 Silverado 5.3L just after it hit 100,000 and the certified GM warranty expired cylinder 7 did not come back after going to V4. Went to the dealer 3 times before they fixed it correctly(knock on wood its been good for a few months). My company paid for the repair since it is their truck but my problem is I have 2018 Silverado Z71 same truck basically same motor and it only has 25,000 mikes on it but I want to override this AFM knowing there is a good chance it will give me a headache down the road. Great truck I love it but the AFM sucks and if I wanted V6 or V4 I would have gotten it.

[@hamm3790]

My 2018 Silverado has been great! Until this last month. Drives shaky especially when going up ANY incline. (And I drive him like a baby) He drove smooth as a car until he hit 55,000 miles. Hoping this trick fixes him. It’s been a great truck until now. I’ve already spent over $800 trying to fix it. Nothing has worked so far. We’ll see after I try L5. I’m already thinking I want an older truck though. Too many high tech issues that are insanely costly.

[@moobutt]

I thought I was the only weirdo that did this 🤣. 2019 Silverado LD company vehicle that just rolled 100,000 And a 2019 Silverado LD Z71 Redline that has 40,000. I’m doing the tranny thermostat delete and Range AFM fix ASAP. I need this one to last.

[@dang5025]

I am wondering if you have the tow button your shifter and how well it works when you are in tow mode?

[@bullofthewoods9374]

tow mode only changes the time of shift. thats it, so if you are in 5th it will stay in 5th. if you are towing you should be in 5th anyway and not have the amf in play to start with. i mean unless you are towing a less than 500 or so pounds. if your towing a camper or bigger boat, why would you be in overdrive anyway. it would be coming in and out like crazy and just wearing out your tranny parts

[@bullofthewoods9374]

also it helps you downshift to stop at least in my allison it does.

[@aliciabrowndocken4660]

I keep hearing everyone wanting to turn off the AFM. I'm a bit confused as to why you would want to do that. I have a Degree in Automotive Technology and Engineering and I am a Retired Toyota Master Technician. I have a 2017 Silverado 1500 Z71 4x4 Long Bed with a 5.3L V8. I ordered it with 3.42 gears in the final drives. It can tow up to 9,500 lbs. I love the fact that I can set the cruise control at 63mph not towing and get 23.7 mpg fuel mileage. The engine is Quiet with No Exhaust Sound. The RPM's are low. The Stereo is Great. If I need to Shit and Get I just drop the Hammer and I'm gone. The AFM Deactivates the Valves on the Inner 2 Cylinders on both Banks and turns off the injectors. It's not Quite as good as a V4 Engine but it does save Fuel and Reduce Emissions. In California the AFM saves me about $15 per each tank full of gas. I understand that the complexities of the system create possible maintenance costs down the road, but the system is already there and paid for when you buy the Truck. AFM saves me sbout $600 a year in fuel.

[@avflyguy]

Supposing you've not seen thousands of posts, not only on KZbin but Google it. My 2015 GMC Sierra Denali with only 45k miles actually broke a pushrod. Damaged lifter and cam. Nearly 3k to get it all fixed. GM offered nothing. It's a industry know problem and *any* of GM's V8's can experience it, potentially more than once.

[@dickhitswater4836]

It’s the thousands it costs to repair the system when it breaks, that’s the issue everyone has with it. It’s a roll of the dice if you’ll get lucky or not and the early versions (I have a 07) run like garbage when it’s activated. Sitting in a rock polisher isn’t much fun considering what you paid for it and now I’m going to be thousand more into it since the system failed. My last truck (00 Silverado) went 389k before I sold it and it was still running great and never needed anything. Average fuel economy was better in the 00 without the AFM and despite what the numbers say was a lot more powerful too. Just my opinion. Pretty sure there’s a class action lawsuit going on because of it. Ford bailed themselves out, keeps pushing quality products out. GM took the bail out and products have gotten worse since. Last GM I’ll buy that’s for sure.

[@bullofthewoods9374]

your first mistake was in your description of yourself, degree in automotive tech and engineering. first the idiots that came up with this terrible system should be sued for bad design. second, the money you save in gas is a far cry from the cost to repair. i just did mine in a 2016 tahoe with 111k miles. Cost was 5400. do the math , i didnt save crap. in fact it cost me money. so to answer your question, thats why people want to turn it off. by the way look up the issues its causing and you will see how really out of touch you are. here is the issue i have with so called engineers, they dont know how to fix what they design and then cant seem to tell people why their designs fail. its a terrible design and im all in for a class action lawsuit ( which i usually despise). I fix engineering screw ups everyday and think all engineers should be in the repair side of the crap they are designing. hope you not that out of touch
