Turn V4 mode off for free. Easily shut off the AFM/DOD system with this trick. 

AFM disabler - a.co/d/1wB9YXZ

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.

Much needed advice! Works on my 2014.

That’s it! My man. Thank you

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

This is amazing

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

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.

Thanks for sharing

It works for my 2015

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

Thanks bro

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

good stuff

Been doing this for 5 years on my 2015 Sierra no issues. But then again I rarely ever have to use the highway or interstate, if I do it’s in D

They don't make a mod for my ppv. Thank you! I was worried about long term effects on my motor, even though I have an oversized oil pump.

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

I noticed that your Silverado has L mode my 2018 LT has M mode. What year is yours?

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.

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

I've been doing this on my Tahoe for a while, L6 does activate V4...

Will this work with the 10speeds?

What about for the newer 10 speeds?

Does this hurt the transmission?

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?

Is this safe to do? Are there any cons or pros of it?

Does it work with older vehicles with D-3-2-1 trans? If I stay in 3 will it defeat the AFM?

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

I've got a range disabler too. My mechanic claims the 4 cylinders don't get oil when the 4-cylinder AFM doesn't engage but I've had no problems.

I leave mine in 4th for around town.

I got rid of it entirely so I can be in 6th gear in v8 mode. Worst thing GM did along with these bull$hit gdi engines.

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.

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

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

When towing my travel trailer I put it into L5

Will this work for the 6 cylinder version of Silverado

Wondering if this works on the 4.3 v6? Keeping it from dropping to 4 cyl

Delete highway gear? Ummm….NO.

I can totally do with out that crazy music. other wise good video.

I'll pay 180 for an AFM disabler, and I'll keep my 6th gear

Does not work on 2013

Why not run it in L6? I ran my 2015 6.2L with the 8L90 in M8 and it never went into V4.

That don't work on a 07 Tahoe

Does m7 work for the 8 speed??

Just bought a used 2017... V4 drives me to drink.

will doing this all the time hurt ur engine or transmission at all ?

Very short term a good way to burn out the overdrive clutches

How many people likes to drive with 4/8 cylinder, since so many people complaint about 4/8 cylinder issues why gm not stop making it 8 cylinder only

Does this work with the V6

Why not drive it in L6?

But what if your lifters are already tapping ??

"Note to self "... drive my new truck like it was designed/engineered to drive.

Now find me something to do to turn the auto start off on the wife's Equinox....

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.

All of that horrible noise in the background makes your video unwatchable. I think you call it music, I call it crap.

Mmmmm 😒 you right. But you keep you truck running on 5 gear and you engine is over RPM

Yikes dude😂

This video sucked. Pay for the disabler.

no proof at all this works you was in v8 the hole time
