I have a 2012 1500 LT 4x4. I hate the variable cylinder crap. I don’t drive in the city much but every time I let off the gas even on the highway it goes through the variable cylinder crap. We towed a trailer that weighed about 6000 lbs from NH to AK when it was a year old. It only has 46,000 miles and we drive it less than 3,000 miles a year now. I.d have to live to be over 100 to get to 150,000 miles so I guess I’ll keep it.
I have a 2014 GMC Sierra 1500 5.3 with 6 speed trans... 147k miles on the clock and no major issues other then regular maintenance and an investment of 199$ for a Range AFM disabler... most people run these trucks without servicing the trans filter and fluid and just get them flushed... this causes major issues down the road and the amount of people who ignore this suffer trans failure... it’s all about how you take care of your machine.
Hello Scotty, I have 2018 Denali 6.2. I installed the RANGE deactivation module in my truck. 199$ cost. Takes the deactivation out. Works perfect. Pass it on.
I am running a Range Pulsar LT in my 2021 GMC Sierra AT4 (6.2L) for three years now. No issues. Stays in V8 mode, no start/stop engine voodoo crap, throttle position bumped up, no speed limiter, etc. Best $500 I ever spent.
The problem is that the bad lifters and cam are still there. Unless you change the cam and lifters and then reprogram the computer, you will possibly still have issues later on.
I believe that's the one that I have in my V6. I had unplugged it because I was worried about the battery going dead and the other day I could feel something weird going on or hear something weird going on so I did plug it back in
@andrewpage9600 how many miles did you have before you installed the AFM bypass - If it was after 100k the damage was mostly done. Did it fail in the 160 to 200k range just curious
No where is like it used to be. I remember 40 years ago having a few vehicles and I just kept the keys in them in the yard and never locked the house. We never locked our vehicles when we were in stores either. I also remember back then a gas station got held up and the owner chased them and shot and killed one of the robbers. The attitude was he got what he deserved and that was the end of it.
aint it the truth now...when scotty talked about ..."even they become confused" and showed the chimp in the lab coat it reminded me of the old aamco transmission commercial, where their competitors would say - our transmissions are never touched by human hands - and then they'd cut away to two monkeys in white jump suits on each side of an automatic transmission hitting it with baseball bats.
Just an fyi I own a 2015 model sierra. Oil changed every 5k, transmission pan dropped with filter replacement and 5 fresh quarts every 50k with zero issues. 185k on the clock.
@@truenorthcanadian5628sadly at around 150,000 miles the valves on the "deactivated" cylinders start to get REALLY weak and start causing a loss of power and can cause even more damage
I have a 2014 GMC 5.3 liter Sierra with 186,000 miles. No problems, other than recently replacing the water pump, which was inexpensive and easy to do. I consistently get 22, 23 MPG at 70 MPH, with cylinder deactivation functioning frequently as I go up/down hills. I fully change ATF once a year. (6 speed tranny) Change oil/filter every 5,000 miles or so using hi grade synthetic oil. Replaced my first set of stock Goodyear tires at 105,000 miles. 2nd set of Michelens looks like they will go 100,000 + as well. Couldn't be more pleased.
i have a 2016 gmc Sierra 1500 with the 5.3 bought it with 100k ( was told straight up from the dealer to just be vigilant on the maint schedule ) on it and had full service records on it i already took it on a few long road trips with no issue . I just make sure the oil is changed every 5k with high quality synthetic oil
I have a 2011 Silverado 5.3 with 137k miles...no transmission issue and shifts smooth enough to not even hear it . Just depends on how you take care of them that goes with all vehicles. I have a small rear main seal leak which I've had on most my gms. That is the only weak point I've experienced and I've owned 6 of them. 2011 is the model I drive now and no issues
I have a 2011 5.3 as well with about the same miles as you. My experience has been the same as yours. Relatively very few issues. I did have to have a seal replaced on my transfer case but engine & tranny have been good. I still got better gas mileage on my old 2000 Silverado with no cylinder deactivation but that one was a 2wd regular cab plus that era had better shaped bodies for aerodynamics
As a retired tech with 47 years at a dealership I totally agree with you Scotty on all counts and what ever happened to a truck with a manual transmission. Can you imagine a Chevy truck with a 5.3 and no cylinder on demand system with a 6 speed stick.
Way way way down the road Im gonna swap mine to a tr6060. A few people have done it and Im just waiting on a decent number to do it so they start making swap kits so I dont have to hunt down parts. Apparently they use alot of stuff from the 5th gen camaros to do the swap.
GM will never stop coming up with ew stupidly stuff... They try to beat others but they get to look cheap, and stupid them selfs.... Soon they will have engine deactivation and never enter the market again
My 5.3 with cylinder deactivation has 240,000 miles. I have done very little to this truck, other than basic maintenance, new front wheel bearings and front driveshaft seals. And I have averaged around 20 mpg for years. On road trips with a friend that drives a Tundra, he averaged 13 mpg, while I was getting 21. Maybe I got lucky and got a good one, but this truck has been very reliable and economical for a big truck.
My 2015 silverado has about 150,000 on it. Oil is changed every 5000 miles at the dealership to keep my drive train warranty in effect. The transmission went out at 128,000. Dealer replaced without any argument. They think it was at least partially caused by the valve sticking closed on the transmission cooler.
I have Silverado 2016 with 150k and had no problems at all its a really great truck . actually the biggest company of oil here in Saudi Arabia use these trucks and they are everywhere in the eastern province and it holds its value a lot. very capable engine.
@@nwabuezeozuzu6370 It does additional damage to engine. Every time the engine shuts off and turns on causes additional engine wear.......all just for saving minimal amounts of fuel. If thats not enough the constant shut off and on of the engine is terribly annoying.........but thats my pers opinion. Scotty did a video on why auto start/stop is bad for your engine as well. May not notice anything the first few years of ownership, but if you want long term ownership, you should prob have that feature disabled. Companies like autostop eliminator make a decent product so that you dont have to push the button every time you start the engine.
The dealer fix for a clunk when stopping was to take the drive shaft out and put a Superball into yoke to cushion the coming together of the yoke and the u-joint.

The cylinder deactivation only occurs when off throttle Also change your oil regularly to help with the gm VLOM the lifters collapse shutting the valves its very important you keep up on oil changes with this system I work at a Chevy dealership and people go to these 19.99 oil change places and they put conventional oil inside and wait until the oil life monitor hits 0% then wait until the next payday to change there oil Just modern engines in general change your oil
Isn't the oil life monitor on a timer rather than how many miles you drive? I have a 5.3L Tahoe that I only drive on the weekends so not many miles, shouldn't I pay more attention to how many miles I drive rather than the oil life monitor? And is 5,000 miles a good time to change oil? Thanks in advance.

Good afternoon Scotty. Late to the video last night I was with my daughter. She got rid of her 2014 Hyundai Elantra GT. She bought a 2020 Toyota Corolla SE( made in Japan) with 8000 miles on it. That makes my wife and both daughters getting Corolla SE within the last 3 weeks 👍✌
The 2013 and 2014 GTs were the best ones made as they came from Osan, Korea. The ones built here had lots of engine problems. I have a 2014 with 167k miles and zero issues. Can’t go wrong with a Corolla though. Had a 2000 with 283k miles and sold it for $2000 with a broken AC system.
I have a 2014 Corolla LE 107.000 miles other than brake(ft) & 2 batteries & oil changes very good car! Keep an eye on the + positive battery terminal seems to get corrosive! good luck! Mine was built in Canada!
Probably the transmission too. I have a 2018 Sierra but 2wd and i just don't feel there's uniformity between the engine and transmission. When you're on hilly back roads. I feel that the cylinder deactivation kind of confuses the transmission a bit.
@@brucemartin2605 Nice yeah that's nothing. Mine leaks more than that but I'm resealing everything when it warms up. Not to tough on an old 350. I'm assuming you have the 5.3 LS, also a super strong platform. Unless you have a 99 classic.
My same Tahoe Z71 has 285k. Runs like a champ. Those 5.3 motors are a beast. The transmissions are straight poo. I'm on my 3rd rebuilt 4l60 in my Tahoe & Sierra. I finally have a shop that knows what they're doing I guess. I never skimp on any rebuild either. Change everything to high end parts. But I learned after fishing the net, forums the 4l60e transmissions are just crap.
I had a 2015 Silverado that had 217,00 miles on it and ran good but had to rebuild torq converter. Got 24 to 25 mpg consistently with 5.3. My 2018 Silverado gets the same milage with a 6.2
My 2010 AlTerrain GMC has that multiple cylinder V8. So far 152,000 miles It uses 1/2 quart oil between oil changes. I use a metal penetrating lube. It makes a difference. Quieter also. Truck is a work horse pull rated 10,700 off road 45 degree grade. I pull out stumps and plow fields. 15 mpg around town 20mpg after 2 hrs on road. My mechanic told me it’s a really good truck. I’m one of the lucky ones.
@@jeffduncan9140 -- Yes. All 7th Generation Corvettes have it (2014 to 2019). With a manual transmission, it only goes into four-cylinder mode when you have the car set to "ECO" mode. In automatic Corvettes, the engine will drop down into "V4" mode whenever it wants to do so. Plugging in the Range AFM device prevents this from happening. Going into V4 mode only saves about 1 mile per gallon, so it is not worth it to potentially damage your engine to save a few pints of fuel on a long trip.
@@1VaDude gotcha. I had no idea. I manage a fleet of Chargers with the same issue. I would love to deactivate that crap but any mods void the warranty.
We drive our Tahoe LTZ 5.3 in M5 around town 50 mph and under. Shifts normal all by itself. Don’t have to manually shift up and down with the switch on the shift lever. It stays on all 8 cylinders. Jump on the highway and then M6, cruising on the highway it will go to V4.
Have the cylinder deactivation on my 2012 Honda Accord V6. There is a guy up in Canada who sells a S-VCM that essentailly eliminates the 6 to 3 cylinder deactivation system. I purchased the car at 57k and the spark plugs were oil fouled from this system. I immediately put the "muzzler" on the VCM system (what honda calls cylinder deactivation) and it has been running great since. Full power in that great honda 3.5L V6. Tons of power. No more bucking of the engine in and out of VCM mode and also no more breaking the costly motor mounts.
Hello Scotty! I bought a Chev Avalanche new in 2011. At first I was amused by the AFM system but just after a few days it really became annoying. The jitter from 4 to 8 cylinders quickly became a thorn in my side. I then realized that driving the truck in Manual Mode and keeping the transmission in 5th gear (not selecting 6th), AFM would not engage. Therefore I have been using the truck like that ever since. The difference in RPM at highway speeds is about 300-500 RPM's higher from using 5th instead of 6th. So far so good as I really believe the extra RPM's shouldn't do any real harm. Anyhow, love your channel and keep up the great work. Blessings and Cheers!
I've read that GMs 4.8L V8, which they discontinued years ago, is very similar to the 5.3L. The only difference, besides displacement, is that the 4.8L did not have cylinder deactivation. Hence, the 4.8L had a better quality rating at the time.
I have one. A 2017 with 3800 miles on it. I put the Range deal on. Cost $200. Runs in V8 at all times and doesn’t shift as much. Works great and all you have to do is pull it out of ODB port and it is stock again with no record on computer that you used the deactivation device. This makes transmission shift better because when it goes into v4 mode the transmission is shifting also and hunting for gears. Mine runs great and smoothly. Also I like the way it runs when in trailer mode. It holds lower gears longer and doesn’t shift as much.
The L83 engine you’re talking about is actually a pretty good engine, all things considered. It’s a pushrod engine based on a proven design. The AFM on 2014-2018 engines is V8 or V4 (no V6). Yes the lifters can fail, but this is completely attributable to poor oil and long oil change intervals. This generation has been on the market for 10 years; frequent oil changes with quality synthetic oil is the key. As for the transmission, the 6 speed is pretty good, just keep up with flushes of the torque converter per the maintenance schedule. Yes, the 8 speed is very problematic; it requires frequent flushes with updated fluid and usually also at least one rebuild of the transmission. We own two the these, both with the 6 speed transmission. One has 350,000 km, the other has 210,000 km. Not a single issue and they’ve only ever had regular oil, filter, and fluid changes. Yes they’ve got their issues, but I’d take a GM anyday over a whimpy Ford, or a Ram death wobble, or a guzzling Tundra with crap payload…
MDS technology in my 09 Ram 1500 w/5.7. 186,000 miles I suffered cam lifter failure. Fixed the problem with a Jasper non-MDS 5.7. engine runs great! The only other thing that would make me feel better is a high volume oil pump or a Hellcat oil pump.
My 2023 GMC 5.3 engine gets 22 mpg on hwy; has 10speed transmission; I traded my 2020 GMC 1500 with 2.7 engine was ok towing but 8 speed tranny going bad; I glad I upgraded to 5.3 engine.
Had a lease 2018 GMC Canyon 10 speed transmission. Gave me problems for 3 years. Now I have a 2021 Toyota tacoma trd off-road and loving every minute of it.
I put in a device that plugs into the OBD port and deactivates the system and works out great. I’ve got over 155k miles and no issues with the engine, oil pressure is always good.
I’ve had both issues with my GMC Sierra 1500 (2015). I had an extended warranty that saved me about $14K. But now I’m at the end of that warranty period and I think I’m going to follow your advice about the deactivation of the cylinders.
Still towing my 7100lb 26ft camper with 219,000 miles. 2015 GMC Sierra 1500 5.3l All Terrain. Only thing I have done is the AC compressor and a battery.
2015 5.3l 6spd , 100,000 km. Do oil and fluids early - zero problems yet. Diablo sport, range technology etc or drive in 5th gear when not on the highway, it stays out of 4cyl mode. Highway speeds the thing has too much air resistance that it needs 8cylinders to push it, anyway.
If you’re gonna put a 4 cylinder engine in a 1500 or larger truck, you really wish they’d use something like the old Detroit Series 50, which was essentially a Series 60 with 2 cylinders chopped off. Great engine for class3-5 trucks.
I don't even want a truck, but I watched this entire video because his videos are just so good. I wish I knew more about auto repair. If Scotty was my neighbor I was ask him to let me be his Jedi apprenticed !
We used to have a mechanic in town who knew his stuff.. but he sold the business to a guy who’s been working under him for several years.. I just hope the guy also knows his stuff
couple things.. 1. that clunk is very common . happens to all of them.. its normal. Tell him to de activate the afm it will shift sooo much better Mine did that same exact thing.
Hey Scotty I saw an article that GM isn’t going to put this Mickey Mouse Deactivation stuff in their new trucks because of the “chip shortage” Like you said, they shouldn’t have ever put ii in their trucks to start with!! Thanks as always for your insight!! Keep up the great work!!
I have cylinder deactivation in my Dodge Charger. It makes a difference on highway driving, but i turned it off with a tuner because it rides smoother that way. There’s a slight hesitation when it goes back to 8 cylinders.
I have a GMC Sierra 2018. The best way I can describe it. It sounds and feels like a clutch slips when you slightly drpress the accelerator pedal. I'm really considering having my engines deactivation deactivated. Not so bad on going onto a highway but on hilly back roads, Eh.. I feel that theres no uniformity with engine and transmission with.the cylinder dectivation system activated.
The 2004-07 Honda Accord hybrid has the same concept, the v6 has a 'hybrid mode' where half the cylinders deactivate, very useful on the highway where you're at a consistent speed most the time but when you're at a stop light or city driving, hybrid mode turns on and for whatever reason you decide to floor it, pray your spark plugs don't fall threw. Would've been my favorite hybrid only if there wasn't huge cables all over the engine bay, making it almost impossible to change spark plugs on the inside cylinders, and if there was also a button to turn hybrid mode on and off. Wouldve been the best but no.
Scotty, ive had my 2017 Chevy Silverado 1500 my truck has 62,000 miles on it and my torque converter had grenaded recently and a GM dealer quoted me a price of $2,800! A 3 year old truck with that kind of miles, i never tow anything or haul anything. They dont make them like they used to.
@Zaguate if i buy another chevy it will certainly be a diesel, they put allison transmissions in the diesels. But still for $40,000+ you think they would last a while...
Same, got me the range afm disabler at 2k miles. Up to 40k now on my 2018 and no issues at all, and crazy part is my mpg didn’t really change. I still get 23mpg highway at 70 mph
@@firesniper14 mine is 08 5.3 with 152k. Engine runs like new. From what Scotty says, I’m worried about the tranny! (Oh no, I’m going to be taken off of YT because of using common word for transmission! 🙄
Just found you recently and been binge-watching. ;-) You have helped me a LOT... was going to buy a Silverado soon, but not anymore.... I don't need to spend 48k$ for a host of issues. I'll just keep my Nissan Frontier 4.0 until it totally dies... and thanks to you, I now know that the water pump is IN-side that 4.0 engine, something I did not know before finding Scotty. I'm going to see if there is a place I can make a donation to you for all the info you've given. And here's a tip in case you didn't know... to clear hazed plastic vehicle headlamp covers, try Mother's Mag Polish. Yep, the stuff used on aluminum. I had some minor hazing on my Frontier plastic headlamps, and just a few minutes hand-rubbing with that stuff and they now look almost factory-new... it's amazing! No water, just a mircoiber towel and a few minutes rubbing. Share with your friends. :-)
I have a 2018 Sierra with the 5.3. I'm considering the cylinder deactivation. Not so much on highway but on hilly back roads. I feel that there's no uniformity between the engine and transmission. It's almost like the transmission kind of gets confused a bit and the only way I can describe it that it sounds and feels like a clutch is slipping when the engine tries to synchronize the deactivation system to kick in to all 8 cylinders. It's kind of annoying actually.
Buy the range technology afm disabler. Keeps your truck in V8 all the time. Bought one for my 2014 Sierra and love it. I hated how mine kept dropping cylinders drove me insane lol. Plus all u have to do is unplug it when u take it to the dealership for service they won’t know so it doesn’t void ur warranty.
I have +250,000 on a 2010 Suburban LTZ 4WD. No smoking or lifter noise on startup, still has plenty of power, does have a slow oil leak, does have the clunking when letting off and getting back on the accelerator, but overall is solid. As with everything, there are some which fail early, some with poor use and maintenance and those which are taken care of and do quite well.
Software deactivation is only good if the valve train is working right, with a soon to be failing lifter, it might not work right. Also, the shop I work for has replaced many belt driven mechanical vacuum pumps, on escalades, silverardos, 1500's, yukons, suburbans, etc. When it fails, you have no brake boost.
V8 naturally aspirated trucks are , at least compared to the 2,7 4zylinder turbo do feel a lot less capable while towing ! My v8 revs like hell if i go uphill and want to keep my speed high. Test drove the 4zylinder and i am sorry to say thats it feels much better. And conserning scottys cylinder deactivation.... it hardly kicks in if you are towing or hauling heavy loads!!! And if you need the power, the engine instandly acitivates all cylinders, sono need to warry bout that.
All manufacturers have issues with engines and transmissions due to government requirements for mileage and emissions. I wish I had my 86 F250 which had a 460 4 speed back. Super easy to work on and durable.
You right about the transmission. I have a 2020 silverado custom an it gets the Shudder. So I drop the pan an put in an new filter an new fluid an it gets rid of it
I have a 2007 gmc with cylinder deactivation and aside from the annoying 3rd gear weak shift I've never had a problem with it. Its at 205,000 miles and still running like new.

Happy St. Patrick's day to you Scotty. ☘️☘️
I have a 2012 1500 LT 4x4. I hate the variable cylinder crap. I don’t drive in the city much but every time I let off the gas even on the highway it goes through the variable cylinder crap. We towed a trailer that weighed about 6000 lbs from NH to AK when it was a year old. It only has 46,000 miles and we drive it less than 3,000 miles a year now. I.d have to live to be over 100 to get to 150,000 miles so I guess I’ll keep it.
"trust in ford"
Be careful Mr. Scotty, your new tent collects a lot of rainwater which could result in an unwanted cold shower!
Scotty, how do in convince my dad out of buying a Dodge Ram and getting a Toyota Tacoma instead?
I have a 2014 GMC Sierra 1500 5.3 with 6 speed trans... 147k miles on the clock and no major issues other then regular maintenance and an investment of 199$ for a Range AFM disabler... most people run these trucks without servicing the trans filter and fluid and just get them flushed... this causes major issues down the road and the amount of people who ignore this suffer trans failure... it’s all about how you take care of your machine.
Hello Scotty, I have 2018 Denali 6.2. I installed the RANGE deactivation module in my truck. 199$ cost. Takes the deactivation out. Works perfect. Pass it on.
Same. Have it in the wife’s Escalade and it works perfectly. V8 all day.
Same here. I’ve had one plugged in for 6 months and I check it all the time to make sure it’s working. Hasn’t failed yet.
I am running a Range Pulsar LT in my 2021 GMC Sierra AT4 (6.2L) for three years now. No issues. Stays in V8 mode, no start/stop engine voodoo crap, throttle position bumped up, no speed limiter, etc. Best $500 I ever spent.
Can the hemi 6.4 gas also be deactivated? For that price $199 or $500? Shoot I read somewhere it cost like $2500.
The problem is that the bad lifters and cam are still there. Unless you change the cam and lifters and then reprogram the computer, you will possibly still have issues later on.
$200.00 OBD AFM bypass runs all cylinders all the time....
I believe that's the one that I have in my V6. I had unplugged it because I was worried about the battery going dead and the other day I could feel something weird going on or hear something weird going on so I did plug it back in
Unhook the brake switch it will no longer deactivate
Won't help. I had one, afm lifter still failed.
@andrewpage9600 how many miles did you have before you installed the AFM bypass - If it was after 100k the damage was mostly done. Did it fail in the 160 to 200k range just curious

No where is like it used to be. I remember 40 years ago having a few vehicles and I just kept the keys in them in the yard and never locked the house. We never locked our vehicles when we were in stores either. I also remember back then a gas station got held up and the owner chased them and shot and killed one of the robbers. The attitude was he got what he deserved and that was the end of it.

I love the pictures you put in the corner, makes learning about cars fun
Scotty picks them very well
aint it the truth now...when scotty talked about ..."even they become confused" and showed the chimp in the lab coat it reminded me of the old aamco transmission commercial, where their competitors would say - our transmissions are never touched by human hands - and then they'd cut away to two monkeys in white jump suits on each side of an automatic transmission hitting it with baseball bats.
Just an fyi I own a 2015 model sierra. Oil changed every 5k, transmission pan dropped with filter replacement and 5 fresh quarts every 50k with zero issues. 185k on the clock.
did you use aftermarket trans oil or buy directly from the dealer
Mine has 122, 000 trouble-free miles and has AVERAGED 22 to 24 MPG numerous times!!!
So far so good!!!
My brother-in-law has the exact same engine. No problems on it either.
@@truenorthcanadian5628sadly at around 150,000 miles the valves on the "deactivated" cylinders start to get REALLY weak and start causing a loss of power and can cause even more damage
I have a 2014 GMC 5.3 liter Sierra with 186,000 miles. No problems, other than recently replacing the water pump, which was inexpensive and easy to do. I consistently get 22, 23 MPG at 70 MPH, with cylinder deactivation functioning frequently as I go up/down hills. I fully change ATF once a year. (6 speed tranny) Change oil/filter every 5,000 miles or so using hi grade synthetic oil. Replaced my first set of stock Goodyear tires at 105,000 miles. 2nd set of Michelens looks like they will go 100,000 + as well. Couldn't be more pleased.
2015 5.3 Silverado. 26 mpg not towing, but 10 mpg pulling the camper. To me cylinder deactivation has paid off.
i have a 2016 gmc Sierra 1500 with the 5.3 bought it with 100k ( was told straight up from the dealer to just be vigilant on the maint schedule ) on it and had full service records on it i already took it on a few long road trips with no issue . I just make sure the oil is changed every 5k with high quality synthetic oil
Have been watching your videos for sometime now, and I do enjoy it because they're educative. Watching you all the way from Nigeria 🇳🇬, Africa.
I have a 2011 Silverado 5.3 with 137k miles...no transmission issue and shifts smooth enough to not even hear it . Just depends on how you take care of them that goes with all vehicles. I have a small rear main seal leak which I've had on most my gms. That is the only weak point I've experienced and I've owned 6 of them. 2011 is the model I drive now and no issues
Agreed. 💯👍If you're gonna drive it like it's NASCAR then it's days are numbered matter what model it is!!
I have a 2011 5.3 as well with about the same miles as you. My experience has been the same as yours. Relatively very few issues. I did have to have a seal replaced on my transfer case but engine & tranny have been good. I still got better gas mileage on my old 2000 Silverado with no cylinder deactivation but that one was a 2wd regular cab plus that era had better shaped bodies for aerodynamics
As a retired tech with 47 years at a dealership I totally agree with you Scotty on all counts and what ever happened to a truck with a manual transmission. Can you imagine a Chevy truck with a 5.3 and no cylinder on demand system with a 6 speed stick.
Way way way down the road Im gonna swap mine to a tr6060. A few people have done it and Im just waiting on a decent number to do it so they start making swap kits so I dont have to hunt down parts. Apparently they use alot of stuff from the 5th gen camaros to do the swap.
Is it possible to put a corvette 5 speed manual in an 04 Silverado?
Still waiting for a response on what scan tool is best to buy for use at home?
Do not believe that GM manufactured many manual transmission trucks with 5.3 engines.
It would make too much sense chevy would never
Scotty is the mechanic friend a bud hopes for.
Go Scotty!!!!!
The good news is that GM have announced that due to the worldwide microchip shortage, newer trucks won't have cylinder deactivation.
They will have engine deactivation.
@@mikefoehr235 LOL
GM will never stop coming up with ew stupidly stuff... They try to beat others but they get to look cheap, and stupid them selfs.... Soon they will have engine deactivation and never enter the market again
And I heard that without the chip it only gets 1 mpg less fuel economy
@@larrysutton654 Hmmm... I wonder if there's an override for it.
Rain look likes its about to drop through that tent! 🌧
Must be a GMC tent 🤣
My 5.3 with cylinder deactivation has 240,000 miles. I have done very little to this truck, other than basic maintenance, new front wheel bearings and front driveshaft seals. And I have averaged around 20 mpg for years. On road trips with a friend that drives a Tundra, he averaged 13 mpg, while I was getting 21. Maybe I got lucky and got a good one, but this truck has been very reliable and economical for a big truck.
I believe changing oil at 3 k with full synthetic helps tremendously driving high miles with no problems
Yes, you got lucky. I spoke with the service manager at my local GM dealersip. Lifter failure is a way of life for his group.
My 2015 silverado has about 150,000 on it. Oil is changed every 5000 miles at the dealership to keep my drive train warranty in effect. The transmission went out at 128,000. Dealer replaced without any argument. They think it was at least partially caused by the valve sticking closed on the transmission cooler.
As a side note it has always gotten 25-28 on the highway. Not bad for a 4x4.
Nice Canadian tuxedo, Scotty. I have the exact same outfit in my wardrobe. My wife loves it!
Invest in a tuner or a OBD Range device and turn active fuel management off before any damage is done. Not much change in mpg.
Got a range 3 days after picking my truck up. Runs great!

@Greg B it seems like it
If a truck has an engine just don’t buy it!! Scotty
i have a 2.7 silverado and it tows great. it doesn't get great mileage when towing but I love it
Agreed, 430 ft pounds and torque!
All cylinder deactivation should b deactivated. Also autostart stop
Why autostart stop?
@@nwabuezeozuzu6370 It does additional damage to engine. Every time the engine shuts off and turns on causes additional engine wear.......all just for saving minimal amounts of fuel. If thats not enough the constant shut off and on of the engine is terribly annoying.........but thats my pers opinion. Scotty did a video on why auto start/stop is bad for your engine as well. May not notice anything the first few years of ownership, but if you want long term ownership, you should prob have that feature disabled. Companies like autostop eliminator make a decent product so that you dont have to push the button every time you start the engine.
@@davea4037 thanks for explaining
The dealer fix for a clunk when stopping was to take the drive shaft out and put a Superball into yoke to cushion the coming together of the yoke and the u-joint.

Love your work Scotty. Thanks for helping regular people stay educated about cars.
The cylinder deactivation only occurs when off throttle
Also change your oil regularly to help with the gm VLOM the lifters collapse shutting the valves its very important you keep up on oil changes with this system
I work at a Chevy dealership and people go to these 19.99 oil change places and they put conventional oil inside and wait until the oil life monitor hits 0% then wait until the next payday to change there oil
Just modern engines in general change your oil
I have this engine. I change my oil with full synthetic Amsoil and a new filter every 4000 miles. Not taking any chances.
Got mine used. Change it with full synthetic every 4-5k/whenever the oil life hits 45% and you’re good.
Isn't the oil life monitor on a timer rather than how many miles you drive? I have a 5.3L Tahoe that I only drive on the weekends so not many miles, shouldn't I pay more attention to how many miles I drive rather than the oil life monitor? And is 5,000 miles a good time to change oil? Thanks in advance.

Good afternoon Scotty. Late to the video last night I was with my daughter. She got rid of her 2014 Hyundai Elantra GT. She bought a 2020 Toyota Corolla SE( made in Japan) with 8000 miles on it. That makes my wife and both daughters getting Corolla SE within the last 3 weeks 👍✌
The 2013 and 2014 GTs were the best ones made as they came from Osan, Korea. The ones built here had lots of engine problems. I have a 2014 with 167k miles and zero issues. Can’t go wrong with a Corolla though. Had a 2000 with 283k miles and sold it for $2000 with a broken AC system.
Corolla family
I have a 2014 Corolla LE 107.000 miles other than brake(ft) & 2 batteries & oil changes very good car! Keep an eye on the + positive battery terminal seems to get corrosive! good luck! Mine was built in Canada!
yup. I have 2011 silverado. I have a AFM disabler plugged in. it will save your engine!
Probably the transmission too. I have a 2018 Sierra but 2wd and i just don't feel there's uniformity between the engine and transmission. When you're on hilly back roads. I feel that the cylinder deactivation kind of confuses the transmission a bit.
Do you leave yours plugged in 24/7?
@Oxnard805 yes. Stays in all the time
You sir are 100% right. That's why you get yourself a 98 with a 350.

My 2010 AlTerrain GMC has that multiple cylinder V8. So far 152,000 miles It uses 1/2 quart oil between oil changes. I use a metal penetrating lube. It makes a difference. Quieter also.

Coworker has a 2016 Silverado. It has the same engine in this video. He bought a device to keep it running on 8 cylinders at all times
It is called a Range AFM device and it plugs right into the OBD-II port. I bought one for my girlfriend's 2019 Corvette Stingray and it works great.
@@1VaDude Of all cars, they put an MDS system in a Corvette?
@@jeffduncan9140 -- Yes. All 7th Generation Corvettes have it (2014 to 2019). With a manual transmission, it only goes into four-cylinder mode when you have the car set to "ECO" mode. In automatic Corvettes, the engine will drop down into "V4" mode whenever it wants to do so.
Plugging in the Range AFM device prevents this from happening. Going into V4 mode only saves about 1 mile per gallon, so it is not worth it to potentially damage your engine to save a few pints of fuel on a long trip.
@@1VaDude gotcha. I had no idea. I manage a fleet of Chargers with the same issue. I would love to deactivate that crap but any mods void the warranty.
We drive our Tahoe LTZ 5.3 in M5 around town 50 mph and under. Shifts normal all by itself. Don’t have to manually shift up and down with the switch on the shift lever. It stays on all 8 cylinders. Jump on the highway and then M6, cruising on the highway it will go to V4.
Have the cylinder deactivation on my 2012 Honda Accord V6. There is a guy up in Canada who sells a S-VCM that essentailly eliminates the 6 to 3 cylinder deactivation system. I purchased the car at 57k and the spark plugs were oil fouled from this system. I immediately put the "muzzler" on the VCM system (what honda calls cylinder deactivation) and it has been running great since. Full power in that great honda 3.5L V6. Tons of power. No more bucking of the engine in and out of VCM mode and also no more breaking the costly motor mounts.
Hello Scotty! I bought a Chev Avalanche new in 2011. At first I was amused by the AFM system but just after a few days it really became annoying. The jitter from 4 to 8 cylinders quickly became a thorn in my side. I then realized that driving the truck in Manual Mode and keeping the transmission in 5th gear (not selecting 6th), AFM would not engage. Therefore I have been using the truck like that ever since. The difference in RPM at highway speeds is about 300-500 RPM's higher from using 5th instead of 6th. So far so good as I really believe the extra RPM's shouldn't do any real harm. Anyhow, love your channel and keep up the great work. Blessings and Cheers!
Theres a dongle you can plug into the OBDII port to disable AFM.
4.3L V6 vortec engine 250km still runs fine all original parts besides the intake and air filter. Love my gmc
Same here with 4,3 Silverado 2017 196000
I've read that GMs 4.8L V8, which they discontinued years ago, is very similar to the 5.3L. The only difference, besides displacement, is that the 4.8L did not have cylinder deactivation. Hence, the 4.8L had a better quality rating at the time.
But they did not have direct fuel injection which really hurts performance and gas mileage.
I have one. A 2017 with 3800 miles on it. I put the Range deal on. Cost $200. Runs in V8 at all times and doesn’t shift as much. Works great and all you have to do is pull it out of ODB port and it is stock again with no record on computer that you used the deactivation device. This makes transmission shift better because when it goes into v4 mode the transmission is shifting also and hunting for gears. Mine runs great and smoothly. Also I like the way it runs when in trailer mode. It holds lower gears longer and doesn’t shift as much.
How is the Range device working for you still? No issues?
The L83 engine you’re talking about is actually a pretty good engine, all things considered. It’s a pushrod engine based on a proven design. The AFM on 2014-2018 engines is V8 or V4 (no V6). Yes the lifters can fail, but this is completely attributable to poor oil and long oil change intervals. This generation has been on the market for 10 years; frequent oil changes with quality synthetic oil is the key. As for the transmission, the 6 speed is pretty good, just keep up with flushes of the torque converter per the maintenance schedule. Yes, the 8 speed is very problematic; it requires frequent flushes with updated fluid and usually also at least one rebuild of the transmission. We own two the these, both with the 6 speed transmission. One has 350,000 km, the other has 210,000 km. Not a single issue and they’ve only ever had regular oil, filter, and fluid changes. Yes they’ve got their issues, but I’d take a GM anyday over a whimpy Ford, or a Ram death wobble, or a guzzling Tundra with crap payload…
Yes no v6 ty. Have a 17 Silverado with the range device 52k miles. I'd like to find a place to completely eliminate the AFM
Doesn't save much on fuel
I could not have said it better myself!!!
MDS technology in my 09 Ram 1500 w/5.7. 186,000 miles I suffered cam lifter failure. Fixed the problem with a Jasper non-MDS 5.7. engine runs great! The only other thing that would make me feel better is a high volume oil pump or a Hellcat oil pump.

I’ve had both issues with my GMC Sierra 1500 (2015). I had an extended warranty that saved me about $14K. But now I’m at the end of that warranty period and I think I’m going to follow your advice about the deactivation of the cylinders.

2015 5.3l 6spd , 100,000 km. Do oil and fluids early - zero problems yet. Diablo sport, range technology etc or drive in 5th gear when not on the highway, it stays out of 4cyl mode. Highway speeds the thing has too much air resistance that it needs 8cylinders to push it, anyway.
If you’re gonna put a 4 cylinder engine in a 1500 or larger truck, you really wish they’d use something like the old Detroit Series 50, which was essentially a Series 60 with 2 cylinders chopped off. Great engine for class3-5 trucks.
The 2.7 is awesome. Try it before you rip on it. Ego buyers hate on it. It was expensive but worth it.
I miss the days of good ol fashioned chevy pickups with the old 5.7l sbc and the old LA series 360 and 318 v8s
I 10000% agree with you. It is ridiculous to have the cylinder deactivation systems. P.K.
Chevy can put a tune where they can run on all 8 cylinders at all times should be solid after that
I don't even want a truck, but I watched this entire video because his videos are just so good. I wish I knew more about auto repair. If Scotty was my neighbor I was ask him to let me be his Jedi apprenticed !
The weird shift problem in these 6 speeds is to completely drain the transmission fluid and replace with this special Mobil fluid.
Well it’s an older video but the new 2.7 puts out 430 lb ft torque 5.3 puts out 383 lb ft torque
Just drive in L9 or L10. DFM and AFM is turned off when you drive in those.
We used to have a mechanic in town who knew his stuff.. but he sold the business to a guy who’s been working under him for several years.. I just hope the guy also knows his stuff
couple things.. 1. that clunk is very common . happens to all of them.. its normal. Tell him to de activate the afm it will shift sooo much better Mine did that same exact thing.
There was a tsb about hard shifts. Change to the new fluid & the shifts smooth out
Hey Scotty I saw an article that GM isn’t going to put this Mickey Mouse Deactivation stuff in their new trucks because of the “chip shortage”

I have cylinder deactivation in my Dodge Charger. It makes a difference on highway driving, but i turned it off with a tuner because it rides smoother that way. There’s a slight hesitation when it goes back to 8 cylinders.
I have a GMC Sierra 2018. The best way I can describe it. It sounds and feels like a clutch slips when you slightly drpress the accelerator pedal. I'm really considering having my engines deactivation deactivated. Not so bad on going onto a highway but on hilly back roads, Eh.. I feel that theres no uniformity with engine and transmission with.the cylinder dectivation system activated.
Unlike the GM engines the HEMIs made after 2009 fail regardless if it has MDS or not because of the cams.
The 2004-07 Honda Accord hybrid has the same concept, the v6 has a 'hybrid mode' where half the cylinders deactivate, very useful on the highway where you're at a consistent speed most the time but when you're at a stop light or city driving, hybrid mode turns on and for whatever reason you decide to floor it, pray your spark plugs don't fall threw. Would've been my favorite hybrid only if there wasn't huge cables all over the engine bay, making it almost impossible to change spark plugs on the inside cylinders, and if there was also a button to turn hybrid mode on and off. Wouldve been the best but no.
Scotty, ive had my 2017 Chevy Silverado 1500 my truck has 62,000 miles on it and my torque converter had grenaded recently and a GM dealer quoted me a price of $2,800! A 3 year old truck with that kind of miles, i never tow anything or haul anything. They dont make them like they used to.
@Zaguate if i buy another chevy it will certainly be a diesel, they put allison transmissions in the diesels. But still for $40,000+ you think they would last a while...
Chrysler HEMI, there is kit you can disable the MDS, the bonus part is it divert more oil to the lifter reducing the risk of lifter failures.
I turned off that off as soon as I bought the truck. Everyone was telling me it won’t effect the engine. Common sense tells you it would. 🤔

I have a 14 with a 3.7 and it actually pulls pretty well
I have +250,000 on a 2010 Suburban LTZ 4WD. No smoking or lifter noise on startup, still has plenty of power, does have a slow oil leak, does have the clunking when letting off and getting back on the accelerator, but overall is solid. As with everything, there are some which fail early, some with poor use and maintenance and those which are taken care of and do quite well.
Scotty should do a contest where you get to send your clunker to him to make a video about.
Software deactivation is only good if the valve train is working right, with a soon to be failing lifter, it might not work right. Also, the shop I work for has replaced many belt driven mechanical vacuum pumps, on escalades, silverardos, 1500's, yukons, suburbans, etc. When it fails, you have no brake boost.
Happy St. Patrick's Day Scotty!
happy st patrick's day!
Range Technology has done wonders for my 9 year old Suburban. No issues.
Hey Scotty, Here is your Crown 👑, Pls take it

V8 naturally aspirated trucks are , at least compared to the 2,7 4zylinder turbo do feel a lot less capable while towing ! My v8 revs like hell if i go uphill and want to keep my speed high. Test drove the 4zylinder and i am sorry to say thats it feels much better.
And conserning scottys cylinder deactivation.... it hardly kicks in if you are towing or hauling heavy loads!!! And if you need the power, the engine instandly acitivates all cylinders, sono need to warry bout that.
Guy at parts store, "why would they do that ?" Because it's gm.
All manufacturers have issues with engines and transmissions due to government requirements for mileage and emissions. I wish I had my 86 F250 which had a 460 4 speed back. Super easy to work on and durable.
GM transmissions a real shift show! 😂
You right about the transmission. I have a 2020 silverado custom an it gets the Shudder. So I drop the pan an put in an new filter an new fluid an it gets rid of it
Got to get the big 6.2L with the ten speed transmission if your going gm
I bet that transmission ain't gonna last long. I hope I'm wrong.
I have a 2007 gmc with cylinder deactivation and aside from the annoying 3rd gear weak shift I've never had a problem with it. Its at 205,000 miles and still running like new.
I know a fair amount about cars, but I’m learning more every day. Thanks Scotty!👍
Gotta disagree with the last note on not adding more gears. Drove an f150 with the 10 speed that Ford and GM collaborated on. And wow, smooth as glass
