I have a 2024 chevy 3500 with the 6.6l gas it works really well. I have pulled 18000lbs with it and was shock how well it did. So far my truck has not used a drop of oil.
That’s good to hear!!! think a lot of people are still hung up on the old gas trucks or just old trucks period… when we had 4 speeds, 5 speeds, etc…. like my 2015 Ram still has a 6 speed trans. Even with its 6.7 Cummins with 450hp 1000torque numbers… a 6 speed still hinders it compared to todays 8 speeds an 10 speeds when towing… That 6.6 Gasser at upper 300hp to the wheels can stay in power easier then before…
@@MXvsATV144 yeah it works good for my needs. All of my trucks before this were all dodges with the cummins. I came from a 2012 dodge 3500 diesel with 6speed manual that I bought new.
@@KingFinishCarpentryLLC I get 14mpg driving back and fourth to work. Alot of small hills. On the highway not pulling anything I got 17-18. Mine is a crew cab long bed 4wd. I am really happy with mine so far. Only complaint I have the rear leaf springs rattle drives me nuts
I have a 2024 3500, and went from a 2008 Duramax Diesel to the 6.6 gas. I was very Leary to make this change however I do not regret it at all. It is a towing beast and I tow all the time. I picked the truck up the 2nd week of July 2023 and it has 30,000 miles on at this time. It gets about 7.5 to 8.0 hauling and I haul very large loads. This is about 1.0 miles per gallon worst then the 2008 Diesel. I am in northern Michigan and Diesel is approximately 1.00 dollars a gallon more then gas all the time. I do not have to deal with Def fluid or regens. GM in my opinion hit the nail on the head with this 6.6 gas mated to the ten speed trans I don’t miss the diesel one bit.
I work for allison. It's not even a allison transmission. We have zero engineering in the 10 spd. It was tested by allison so we could give it a thumbs up. It's branding at its finest.
It's a good transmission. Saves mileage for sure. Just keep it serviced. I do agree that the internal filter is annoying but it does make you properly clean the pan. The filter is a lot bigger too. It runs cooler also.
Branded or not, a company with a reputable reputation wouldn’t brand something not good. That’s like you endorsing an employee to get hired who has zero good work ethics and calls out. I’m pretty sure you wouldn’t stamp or approve that. Allison would mess up their money with their name on something that wasn’t good.
Thanks for the video.I just bought my 2024 Chevy Silverado 2500 HD custom crew cab 4x4 it now has 3600 miles on it. We have towed our 7000 lb travel trailer with it and the truck is unbelievable we have to watch our speed because we forget it’s back there. The 10 speed transmission is flawless in this truck in my opinion. Gas mileage? Who cares! I bought it for comfort,tow capacity,and overall safety for my family. Now looking to buy a bigger trailer 😂. Buy one of these you won’t be disappointed.
@trucker2001. just got my Chevy 2025 HD 2500, Z71, LTZ , 6.6 liter, 10 speed Allison transmission, Sunroof, Crew cab 4x4 with the HUD display, Leather seats thru out, this girl has all the bells and whistles, all digital, What a Beast. Still going thru the break in period. This truck just cruises. I love that Hud display tho.💪. Gas mileage sucks for sure but I'm praying Trump wins tomorrow. LOL🤣🤣🤣.
Correct info on GM transmission: Ford and GM jointly designed their 10 speed tranny. At the end of the process each of them “tweaked” their own design to make them unique but they are 90% the same. GM pays Allison royalties to use their name still but the transmission was not designed or manufactured by Allison.
Here in rust belt Ontario, its interesting to hear about the different engines and transmissions, but for me its all trumped by the better paint on the Ford frames and the aluminum body. Have a 2017 F250 6.2L 6speed with 237k km and the body is still perfect and the frame almost perfect.
I bought a brand new 23 6.6 gas 3500 knowing the 10 speed was coming. I don’t mind it one bit. It tows well and not worried about def/emissions is great also!
Just bought a 2024 Chevy 2500 with the 6.6 gas/10speed a couple weeks ago. Couldn't even make it to the first oil change before the rear brakes started dragging all over town at 2100 kms. Driving a rental car for the weekend while the new 80k trucks sits at the dealer.
I bought a 2024 2500HD gasser last year and I'm loving it. the 6.6 and 10-speed transmission combination has been fantastic for me. We're on a spring break RV trip and crossed 11k miles with it yesterday. I love towing with it. It makes our family trips so much more enjoyable for me. I do agree though, fuel economy isn't great, but that wasn't why I bought the truck, so I don't mind.
Rhank you for taking the time to produce this video. Please forgive me, as my truck is the Duramax diesel. I bought a used 2023 Chevrolet silverado 2500hd duramax. 66k on the odo. I bought this truck to haul my bumper pull camp trailer, wieghing in at 8k loaded and light use. I also bought it for the engine and Allison transmission. After purchasing it, I read online of issues a lot of owners having with the 10 speed transmission in the 2500 and 3500 trucks, jumping into different gears, locking up the rear wheels, going into limp mode, stuck in 6th gear on the hwy, etc. Concerned, I went to my local dealer, and they looked up the vin. of my truck. The history shows the valve body was replaced in the transmission at 61k under warrenty. I currently am not experiencing shifting problems with mine. But im concerned I may in the near future. Could anyone shed some light on this topic or have others had this issue with their 2020- 2025 Chevrolet or GMC 2500-3500 10 speed in diesel?
I picked up a 24 heavy duty gasser November 1st. I have 5,300 mi on it. No complaints. No oil usage. Plenty good acceleration for me. No issues of any kind. I get 12 to13 mpg in Wisconsin Winters. I actually got 21 one time and yes I did check it by hand but all highway with no wind at 58 mph. Mainly getting 15 to 17 mpg, but that's going 70 to 75 mph.
I own 2024 Chevy 2500 diesel and that truck is like a cloud, no problems with the transmission and it is realy smooth, best truck i have ever owned, and I have owned Dodge, ford F 250, so far the chevy beat Ford to the moon and back.
10 months ago I bought the 2024 6.6 gas with the 10 speed Alison transmission. At 28 thousand experienced a hard shift when shifting down at 25 to 3000 Rpms and the transmission whould not shift to higher gears .this happened while towing only 6700 lbs going on east bound I 80 in Wyoming,
Different trans, but I have a 2022 GMC 6.6 gas 4x4. does not use any oil, no issues of any sort. Have had a catch can on it from new, usually 2 tablespoons of oil every 2k miles. My lifetime average with 22k miles is 14.6, mpg with lots of cold weather and 4x4 use. On longer trips with cruise, unladen, I get close to 18.
I had the same truck. It was a lemon from jump. 4 attempts to seal my rear window that leaked. I then came to find out it was a flaw in the body itself. They didn't believe me about the terrible hard shifting, and down shifting until they pulled the trans. pan to find metal fragments from the torque converter. Long story short, it got rebuilt at 12,000 miles then, started doing the same thing. Lost my ass getting rid of it with interest rates that went up.
The GM/ ford 10 sp is used in the LD trucks and cars. Believe this is a whole different animal. GM calls their version the 10L100, This one is called 10L1000 and is PTO capable.
I have a 24 ZR2 with the 6.6 gas. Truck drives great and the transmission shifts very smooth. Acceleration feels great down low and around town. It does feel a little flat up top though. Basically feels like most of it's power is in the 1st 1/3 of the peddle. Putting it to the floor doesn't give you much more acceleration. Good overall, if they could give it more pepp up top, it would be perfect.
The 6.6L Gas Silverado is a great truck with a reliable powertrain. The new interior and new 10 speed really helped bring out the potential with this generation. My only complaint is fuel economy (which is terrible in all HD trucks) and price. The prices of these GM gassers are less competitive than similar Fords even when both are well used.
I would like to point out to potential consumers that an important portion of this video feels misleading. I recently purchased a 2024 2500HD with the L8T (6.6 gas) and the transmission is definitely NOT the GM/Ford codeveloped lighter duty 10L80 that is put in the 1500 trucks. The transmission is most definitely the GM/Allison codeveloped 10L1000 that comes behind the Duramax in the HD trucks since 2020. Of course it needs a different torque converter, shift points, etc to work with the gas engine(hence the different part number), however, it is essentially the same HD trans that weighs ~360 lbs vs the lighter duty 10L80 that weighs about 230 lbs. I say this with confidence, I crawled under my truck before I bought it, and examined the trans itself and transmission pan shape and bolt pattern to be sure. It is correct that Allison doesn't build it, GM does, they just worked together during the design and testing, but that has been the case for DMax HD transmissions since 2020 as well.
I think because of the common confusion Wikipedia has been edited to be incorrect on this one by including the 10L1000 on that list. There is a video of a GM Chief Engineering talking about the 10L1000 where he specifically states it was not developed with Ford like the smaller 10L80, and that it was developed and then tested in collaboration with Allison to their standards. I will attach to links in a reply below since my last reply with the links got deleted.
It won't let me add the video, its called "Allison 10-speed transmission in 2020 Silverado HD" by Hard Working Trucks, its the engineer speaking about the 10L1000 transmission. You can also find more specific info by searching "dieselhub 10L1000" on the web.
@@folkenheath Thats what ive been told as well. The 10L80 is lighter and not the same as the 10L1000. If its the same, no way it'll be capable of towing that much
I have a 2022 F350 Tremor with 7.3 gas. The skip shift can be annoying because it can bog down between those big shifts, so I drive around town in tow haul mode which makes it run thru all the gears. Much smoother too. The transmission really runs smooth with a load behind it.
Any automatic transmission with many gears is a high wear unit, more moving parts equals premature wear. I would prefer a manual 6 speed transmission. I currently own a 2011 hd3500 with a 6.0 gas and a 6l90 transmission, got 150,000 miles on the original transmission, i replaced it with a custom unti from ATI. Best thing i ever did. Chevy needs a manual transmission for sure.
Nice video. I’ve been looking forward to this and especially the towing video. I think you will be able to disprove the common narrative that still shows up from other comments I’ve read, and that’s about the “lack of power” of the 6.6. It’s just false. As for the 10 speed, fuel economy won’t be any better. I actually think it could be slightly worse. But regardless, 8th and 9th gear is the same ratio as 5th and 6th was, and then 10th is just slightly taller OD gear. The real benefit to the 10 speed will be towing on grades and then like passing power 40-70 mph stuff. 0-60 will almost certainly be slower because the 6 speed trucks hit 60 mph in 2nd gear and the 10 speed trucks have to shift to 3rd. Shifting takes time so don’t be surprised if you find out the 0-60 is slightly slower. The lack of power comments are just laughable. Anyone that says that has very clearly never drove one of the trucks.
I’ve got a 2024 2500 gas. The biggest issue i’m having is a strange grinding noise in gears 5-6. I’ve taken it to the dealer several times, and they said GM is aware of the issue, but there’s no solution at this point. I’ve towed over 10k lbs often and it does great.
I have a 23 F350 with the 7.3. I have a buddy that has the 6.6 gas with the 6 speed. That isnt a very good match for that engine at all. Good to see the 10 speed helps out.
I have 3 10 speeds in my fleet, one f150, one t350 and one f350 all 2021+ or newer. And I will tell you when you mentioned the skip shifting I realized what I was experiencing. It’s not a bad shift but more an awkward shift usually in traffic between 4-6. Other than that no complaints I love the 10 speed especially in the super duty. What a difference.
Hey I believe shifting is better with the Chevy/Gmc . My friend just had his Ford 10 speed replaced. The dealer kept doing computer updates but it wasn’t working. I would definitely go with the GMC
Hey I believe shifting is better with the new ford/ford. My friend just had his gmc/chevy 10 speed replaced. The dealer kept doing computer updates but it wasn’t working. I would definitely go with the Ford
Great job on the videos, excellent reviews. I’m between the chev 6.6 gas and the ford 7.3 - towing a 9000lbs travel trailer, if both were priced the same what would you suggest? Cheers, Dave from Newfoundland! Can’t wait for the next video on this one!
Can't wait to see how it tows! I'm still on the fence on the 6.6 and 7.3 but this vid and the new interior ( finally ) is leaning me toward GM. We'll see what the tow vid shows. I'll check back then and thanks for the vid! 👍
I had originally thought that as well but turns out all the 10 speed originated from that project. en.wikipedia.org/wiki/Ford%E2%80%93GM_10-speed_automatic_transmission
@@GettysGaragewhile that Wikipedia article exists and someone wrote it like it was true, there is no actual references/notations to it being true provided on that article. Essentially the same as some rando on the internet claiming it.
Great video I wish the hood scoop was functional for adding like an aftermarket cold air intake for good airflow. Also in 2024. Why can we not get standard LED headlights? Also, I wish they would make a plug-in play tuner for the gas burners like a super chip tuner.
Thank you sir! It would be nice because in the Duramax hood scoops are functional so it wouldn't be too much of a stretch to make the gas engines also functional.
@@GettysGarage I have a super chip tuner for my 2005 gas burner GMC Sierra that makes a world of difference not as much as it would a diesel but a good updated tuner for the 2024 would be great and add more horsepower and torque
@thegettyadventures I picked up a 2021 with 60k km. Do you think I should install a catch can? So far I like the truck, decent hwy mileage for what it is (12.3L/100km at 100) Stop and go it gets worse of course. Looking forward to trying it out towing my RV this summer.
Anyone else have the engine lock up or have metal in the oil pan after hearing a slight ticking noise? just had the engine, radiator and AC compressor replaced on our 10 month old truck. Trans issues but "unable to duplicate" so far with dealer.
About time it got the 10 spd! Main reason, is they ditched the 4.10 gears around 2019, the 6.6 might good but i wasnt get rid of the best gear ratio good. 10 spd should evened that problem out
None of the 6.6 have cylinder deactivation in either 3/4 or 1 ton in any year. GM will not due that in their heavy duty trucks and that’s a great thing.
I have a 2024 with the 10 speed. I’m having a very hard shift from 7th to 8th gear. I have just over 12,000 miles on it. I’m hoping they can do a relearn on the TCM when I bring it in to the dealership. All other shifts are smooth. You can’t even tell when it shifts except 7th to 8th. 😢
You driving a truck that weighs like 8,000lbs 96mph? Lots of energy to put into a wreck, not to mention no shot the speed code on your tires support 90+mph
Good video, I am curious how the truck, as a whole, stacks up against the F-250 7.3 and Ram 2500 6.4 Hemi. The transmission and some minor tweaks to an engine can make a major difference. Looking forward to the next one!
having towed with all 3, I would say the 7.3L is the best excepecially with the options of 4.30 gears. the 6.4L hemi is nice with the 4.10 gears and will get the job done. the 6.6L with the 6 speed was certainly at the tail end. Granted with the 10 speed maybe that will change!
The direct injection would be a no go for me. My works trucks have to idle every day for hours. I would be afraid this would be a problem with this engine.
I mean that much idling isn't great for any engine but yes possibly the direction injection would cause more issues then a traditional port injection set up.
I didn't think any GM pickup badged Allison transmissions were Allison built. GM sold their interest in Allison in 2008 when they were cash starved before bankruptcy.
could be, I believed the allison 1000 units that were in the earlier duramax trucks were legit allison transmissions. those same units were in schools buses and all kinds of medium duty applications.
I'm not very well versed in automatic transmissions. we just don't see very many on the HD diesel side of things. But these boys wrote up a nice piece about issues on the 10L1000 nextgendiesel.com/blogs/transmissions-101/transmissions-101-allison-10l1000-problems-solutions-upgrades?_pos=2&_sid=5d125d919&_ss=r
Does any Pickup Truck Company make a Manual 8 to 10 speed transmission. They have been needed since pickup trucks began towing Gooseneck trailers for work. It probably started in the late 50s or early 60s.
Would you please go back a previous about you 1500 you had and the valve cover oil leak I wrote a question on there I’d love to get an answer from you!
I feel like most of these heavy duty gas engines are planned to fail with 6.6 direct injection and both 6.4 and 7.3 having crappy oil pumps. Also the 6.4 has MDS for some unknown reason.
That’s to be expected. Built in obsolescence has been a thing with the big three auto manufacturers for decades. Now they design them to be recycled too.
Hopefully it locks out 1st gear when not towing. I actually paid blackbear performance to do this for me with a 6 speed auto, it was brutal with 4.10's how short 1st was
I know it does that on the duramax. Like the video is all about though... It's not exactly the same transmission. It really does make it much better to drive when starting in second when not towing with the duramax.
I’m getting 14l per 100 best and 15l average on my brand new 6.6 gas with the 10 speed and I only have 750km on the tuck so it will improve when broken in
@@ffarmchicken personally I think they’re the same. What he’s referring to is probably true too but only for a different calibration. I’m sure they have the gas ones calibrated differently for the loss in torque from the diesel.
i drive ford expedition eco boost 3.5 with 10 speed the skipping is really bad and it hunts for gears every time i change the drive mode to "towing" so it does not skip gears and that turns out to be smoother like butter
Make some sense. I've heard a couple people talk about the ford 10 speeds being a little frantic. The super duties and the f150's or for your case the expedition do use different units.
@@GettysGarage I drive a 24 GMC 2500 duramax first GM vehicle ever always run Ford and so far I love it. Only had it a few months so time will tell if I made a mistake leaving Ford or not.
I just can’t get over the new design. It’s a truck and it should look tried and true, not gimmicky like a Tesla. I think Ram and Ford have the styling hands down.
I can echo the previous comment with my 2024 GMC 3500 6.6l gas with the ten speed being a very capable combo and a real joy to tow with. No oil consumption for me either. Now at 6500kms.
I have the 2024 GMC 3500HD gas, no complaints after 480 miles, but I would like a dipstick! I did have a recall for the aux battery that might not be charging, 3 hour software update done at the dealer yesterday.
I love the 10 speed on my 2024 L5P. Only weird thing is every time I underbody was my truck the check engine light comes on and then goes away. The duramax is great but unfortunately I had to have my EGR replaced at 9k miles and my tow mirrors replaced. Kinda leaning towards a Toyota tundra with the v6.
The simple truth is if you tow a lot, diesel makes a lot of sense. If you tow in the summer a half dozen times a year, don’t be stupid and save the money. You might get your macho bragging rights, but you won’t win any smart awards.
@taylorsvilletony773 didn't know that, what kills me when people ask if gm got Allison's stamp of approval when in all reality gm is allison or was for years!

I had the same truck. It was a lemon from jump. 4 attempts to seal my rear window that leaked. I then came to find out it was a flaw in the body itself. They didn't believe me about the terrible hard shifting, and down shifting until they pulled the trans. pan to find metal fragments from the torque converter. Long story short, it got rebuilt at 12,000 miles then, started doing the same thing. Lost my ass getting rid of it with interest rates that went up.
It would be neat to see this truck in a tow comparison vs. A LML powertrain of the past to see the difference
That would be cool, I have an LMM and my next truck will probably be this 6.6 gas L8T.
The GM/ ford 10 sp is used in the LD trucks and cars. Believe this is a whole different animal. GM calls their version the 10L100, This one is called 10L1000 and is PTO capable.
I have a 24 ZR2 with the 6.6 gas. Truck drives great and the transmission shifts very smooth. Acceleration feels great down low and around town. It does feel a little flat up top though. Basically feels like most of it's power is in the 1st 1/3 of the peddle. Putting it to the floor doesn't give you much more acceleration. Good overall, if they could give it more pepp up top, it would be perfect.
The 6.6L Gas Silverado is a great truck with a reliable powertrain. The new interior and new 10 speed really helped bring out the potential with this generation.
My only complaint is fuel economy (which is terrible in all HD trucks) and price. The prices of these GM gassers are less competitive than similar Fords even when both are well used.
I test drove one yesterday, I really liked it. I think I am going to order me the GMC version though, I hate that Chevy front end.
The GMC 2024 HD trucks are probably the best looking trucks right now. In my humble opinion lol
I would like to point out to potential consumers that an important portion of this video feels misleading. I recently purchased a 2024 2500HD with the L8T (6.6 gas) and the transmission is definitely NOT the GM/Ford codeveloped lighter duty 10L80 that is put in the 1500 trucks. The transmission is most definitely the GM/Allison codeveloped 10L1000 that comes behind the Duramax in the HD trucks since 2020. Of course it needs a different torque converter, shift points, etc to work with the gas engine(hence the different part number), however, it is essentially the same HD trans that weighs ~360 lbs vs the lighter duty 10L80 that weighs about 230 lbs. I say this with confidence, I crawled under my truck before I bought it, and examined the trans itself and transmission pan shape and bolt pattern to be sure. It is correct that Allison doesn't build it, GM does, they just worked together during the design and testing, but that has been the case for DMax HD transmissions since 2020 as well.
en.wikipedia.org/wiki/Ford%E2%80%93GM_10-speed_automatic_transmission
I think because of the common confusion Wikipedia has been edited to be incorrect on this one by including the 10L1000 on that list. There is a video of a GM Chief Engineering talking about the 10L1000 where he specifically states it was not developed with Ford like the smaller 10L80, and that it was developed and then tested in collaboration with Allison to their standards. I will attach to links in a reply below since my last reply with the links got deleted.
It won't let me add the video, its called "Allison 10-speed transmission in 2020 Silverado HD" by Hard Working Trucks, its the engineer speaking about the 10L1000 transmission. You can also find more specific info by searching "dieselhub 10L1000" on the web.
ruclips.net/video/lBocpjvch8M/видео.html
@@folkenheath Thats what ive been told as well. The 10L80 is lighter and not the same as the 10L1000. If its the same, no way it'll be capable of towing that much
I have a 2022 F350 Tremor with 7.3 gas. The skip shift can be annoying because it can bog down between those big shifts, so I drive around town in tow haul mode which makes it run thru all the gears. Much smoother too. The transmission really runs smooth with a load behind it.
Any automatic transmission with many gears is a high wear unit, more moving parts equals premature wear.
I would prefer a manual 6 speed transmission.
I currently own a 2011 hd3500 with a 6.0 gas and a 6l90 transmission, got 150,000 miles on the original transmission, i replaced it with a custom unti from ATI. Best thing i ever did.
Chevy needs a manual transmission for sure.
I'm really hoping the manual will make a comeback... but I highly doubt it.
Unfortunately it’ll never happen. The demand is too low for them to ever consider it.
Nice video. I’ve been looking forward to this and especially the towing video. I think you will be able to disprove the common narrative that still shows up from other comments I’ve read, and that’s about the “lack of power” of the 6.6. It’s just false.
As for the 10 speed, fuel economy won’t be any better. I actually think it could be slightly worse. But regardless, 8th and 9th gear is the same ratio as 5th and 6th was, and then 10th is just slightly taller OD gear.
The real benefit to the 10 speed will be towing on grades and then like passing power 40-70 mph stuff. 0-60 will almost certainly be slower because the 6 speed trucks hit 60 mph in 2nd gear and the 10 speed trucks have to shift to 3rd. Shifting takes time so don’t be surprised if you find out the 0-60 is slightly slower.
The lack of power comments are just laughable. Anyone that says that has very clearly never drove one of the trucks.
I’ve got a 2024 2500 gas. The biggest issue i’m having is a strange grinding noise in gears 5-6. I’ve taken it to the dealer several times, and they said GM is aware of the issue, but there’s no solution at this point. I’ve towed over 10k lbs often and it does great.
I have a 23 F350 with the 7.3. I have a buddy that has the 6.6 gas with the 6 speed. That isnt a very good match for that engine at all. Good to see the 10 speed helps out.
Ya when I drove the 6.6L with the 6 speed it was a little underwhelming lol
Make available a 7 speed manual with a really low creep gear and a heavy duty clutch. Then take my money!
Those days are gone. The majority of drivers these days are not mechanical inclined and want all the creature comforts.
I would love a manual on my 6.6
No one knows how to drive a manual anymore
@@garybradley5143 really sad!
I have 3 10 speeds in my fleet, one f150, one t350 and one f350 all 2021+ or newer. And I will tell you when you mentioned the skip shifting I realized what I was experiencing. It’s not a bad shift but more an awkward shift usually in traffic between 4-6. Other than that no complaints I love the 10 speed especially in the super duty. What a difference.
Hey I believe shifting is better with the Chevy/Gmc . My friend just had his Ford 10 speed replaced. The dealer kept doing computer updates but it wasn’t working. I would definitely go with the GMC
Hey I believe shifting is better with the new ford/ford. My friend just had his gmc/chevy 10 speed replaced. The dealer kept doing computer updates but it wasn’t working. I would definitely go with the Ford
There the same tranney that us made by ford
Great job on the videos, excellent reviews. I’m between the chev 6.6 gas and the ford 7.3 - towing a 9000lbs travel trailer, if both were priced the same what would you suggest? Cheers, Dave from Newfoundland! Can’t wait for the next video on this one!
Either will get the job done.
Can't wait to see how it tows! I'm still on the fence on the 6.6 and 7.3 but this vid and the new interior ( finally ) is leaning me toward GM. We'll see what the tow vid shows. I'll check back then and thanks for the vid! 👍
the interior is a REALLY nice addition. and this truck is only a LT trim but it comes standard. I'm pretty pumped to see the difference towing.
we have 2 chevy 3500 10 speed and 1 ford 7.3 4.30 gears you cant compare the two -7.3 ford all the way chevys front rides a little better
Automotive inquiries on RUclips has a good review 6.6 vs 7.3
I'm getting one soon, I like the LTZ trim for the seats
I believe they codeveloped the light duty 10 speed, but not the heavy duty platform 10 speed.
I had originally thought that as well but turns out all the 10 speed originated from that project.

Great video I wish the hood scoop was functional for adding like an aftermarket cold air intake for good airflow. Also in 2024. Why can we not get standard LED headlights? Also, I wish they would make a plug-in play tuner for the gas burners like a super chip tuner.
Thank you sir! It would be nice because in the Duramax hood scoops are functional so it wouldn't be too much of a stretch to make the gas engines also functional.

Is there Cam phasers,DEVCT or cylinder deactivating? If not it seems like a good set up to me.
There is not, thankfully
@@TheBamster00 sounds like a good Truck 👍
No cylinder deactivation, but does use variable valve timing
@thegettyadventures I picked up a 2021 with 60k km. Do you think I should install a catch can? So far I like the truck, decent hwy mileage for what it is (12.3L/100km at 100) Stop and go it gets worse of course. Looking forward to trying it out towing my RV this summer.
I’ll stick with my 2013 HD2500 6.0 4x4 gas base model … no frills & still running strong with 200k miles 🇺🇸
Sweet review Getty
I trust your word
I am still undecided
My 2023 Ford 10 speed with the 7.3 does not skip gears.
My 2014 Allison transmission is still working perfectly, let’s see how long the GM Allison lasts.
Anyone else have the engine lock up or have metal in the oil pan after hearing a slight ticking noise? just had the engine, radiator and AC compressor replaced on our 10 month old truck. Trans issues but "unable to duplicate" so far with dealer.
Excited to see how she tows
Automotive inquiries on RUclips has a pretty good review of the 6.6 vs 7.3
Your reviews are amazing 💯🤘❤️
About time it got the 10 spd! Main reason, is they ditched the 4.10 gears around 2019, the 6.6 might good but i wasnt get rid of the best gear ratio good. 10 spd should evened that problem out
I want to eco a question below. Does the 6.6 gas use cylinder deactivation of any kind? (Specifically the current rear 2024)
My 22 does not
No
None of the 6.6 have cylinder deactivation in either 3/4 or 1 ton in any year. GM will not due that in their heavy duty trucks and that’s a great thing.
@@MMatte75 agreed!
NO, one of best decision GM made.
I have a 2024 with the 10 speed. I’m having a very hard shift from 7th to 8th gear. I have just over 12,000 miles on it. I’m hoping they can do a relearn on the TCM when I bring it in to the dealership. All other shifts are smooth. You can’t even tell when it shifts except 7th to 8th. 😢
interesting, I'd definitely have the dealership take a look at that.
@@GettysGarage I set up an appointment for April 4

How about doing some comparisons between Ford, Chevy and Dodge comparing how their frames, suspensions and other systems are built?
How did it compare to-your PW , in power feel.
please get your facts straight ford and gm did not partner on this transmission only on the light duty 10 speed in the half tons
Ford and Chevy co-designed the light duty 10-spd... Not the HD.
I have one has been great only gripe has been the dealer wants $700 to change the tranny fluid
that's the dealership for ya.
Wonder if the gas spec trans would hold up to a supercharger? But then you're bringing the cost up to diesel territory....
How dd you get yours past 96MPH? I have the GMC Denali 2500HD and it won't go past 96
He was driving in kilometres. These trucks are governed so you don’t tow 20k pounds at 200 mph.
You driving a truck that weighs like 8,000lbs 96mph? Lots of energy to put into a wreck, not to mention no shot the speed code on your tires support 90+mph
In the States, there is a speed limiter of 98 mph on the 2500HD.
In canada the limiter is set to 160 kmh
Good video, I am curious how the truck, as a whole, stacks up against the F-250 7.3 and Ram 2500 6.4 Hemi. The transmission and some minor tweaks to an engine can make a major difference. Looking forward to the next one!
having towed with all 3, I would say the 7.3L is the best excepecially with the options of 4.30 gears. the 6.4L hemi is nice with the 4.10 gears and will get the job done. the 6.6L with the 6 speed was certainly at the tail end. Granted with the 10 speed maybe that will change!
Looking forward to the towing vid!
I honestly really wanted to like the new Chevy HDs but man those seats are absolute murder.
The direct injection would be a no go for me. My works trucks have to idle every day for hours. I would be afraid this would be a problem with this engine.
I mean that much idling isn't great for any engine but yes possibly the direction injection would cause more issues then a traditional port injection set up.
I didn't think any GM pickup badged Allison transmissions were Allison built. GM sold their interest in Allison in 2008 when they were cash starved before bankruptcy.
Those were real turds. @@VAFarmer318
could be, I believed the allison 1000 units that were in the earlier duramax trucks were legit allison transmissions. those same units were in schools buses and all kinds of medium duty applications.
Haha. Typed that comment before I heard you in the video say the exact same thing. lol. Ignore my reply above.
You mentioned, issues with 10 speed. ?? Thoughts
I'm not very well versed in automatic transmissions. we just don't see very many on the HD diesel side of things. But these boys wrote up a nice piece about issues on the 10L1000

I thought the fuel mileage was bad in my 2023 Ram 2500 Power Wagon, but this new 6.6 is a heavy drinker... I get 13.2 MPG with my Ram.
Is Allison really still Allison? Didn’t they license the name?
I can live with poor mpg if I’m not stuck with repairs.
Reliability is number one with me too. My life depends on it.😮
Does any Pickup Truck Company make a Manual 8 to 10 speed transmission. They have been needed since pickup trucks began towing Gooseneck trailers for work. It probably started in the late 50s or early 60s.
No, never have.
Would you please go back a previous about you 1500 you had and the valve cover oil leak I wrote a question on there I’d love to get an answer from you!
Great info.
But is it a workhorse?? 🤔
I've put 70k on mine in 2 years. It's also married to a gooseneck 24/7
I've always been a GM guy, but if I had to buy a new truck, it would be a Ford F250 with the 7.3. It's just got more balls.
I feel like most of these heavy duty gas engines are planned to fail with 6.6 direct injection and both 6.4 and 7.3 having crappy oil pumps. Also the 6.4 has MDS for some unknown reason.
That’s to be expected. Built in obsolescence has been a thing with the big three auto manufacturers for decades. Now they design them to be recycled too.
I've got a F150 10 speed and it's 100% the skip shifting that makes it "rough"
Hopefully it locks out 1st gear when not towing.
I actually paid blackbear performance to do this for me with a 6 speed auto, it was brutal with 4.10's how short 1st was
I know it does that on the duramax. Like the video is all about though... It's not exactly the same transmission. It really does make it much better to drive when starting in second when not towing with the duramax.
I’m getting 14l per 100 best and 15l average on my brand new 6.6 gas with the 10 speed and I only have 750km on the tuck so it will improve when broken in
You’re the only person that said the transmission is not the same as the diesel.
I noticed that too. Even at dealerships they don’t mention there are two different part numbers. 😮
@@ffarmchicken personally I think they’re the same. What he’s referring to is probably true too but only for a different calibration. I’m sure they have the gas ones calibrated differently for the loss in torque from the diesel.
The Allison 10-speed tranny is actually built by GM. They just pay to use the Allison name.
I’ve got the ‘24 2500HD with the gas motor. So far getting 13.5mpg. Only complaint is my 5’ girlfriend has to literally climb into it, it’s too tall.
6.6 vs 6.4 which is better?
Is there particulate filters in the new 3.5L tundra?
I think particulate filters are only in diesel’s
that's a negative. for now..
@@GettysGaragethank you
Which new truck has true Allison transmission?
i drive ford expedition eco boost 3.5 with 10 speed the skipping is really bad and it hunts for gears every time i change the drive mode to "towing" so it does not skip gears and that turns out to be smoother like butter
My wife has one and I never notice it skipping gears or hunting in normal mode.
do you think a women will notice ? @@lancelamoon6743

I can echo the previous comment with my 2024 GMC 3500 6.6l gas with the ten speed being a very capable combo and a real joy to tow with. No oil consumption for me either. Now at 6500kms.
Great engine and truck
This V8 is a basic motor no shutting down cylinders at highway speeds to save fuel ??
Thats a shame they didnt carry the transmission over. Ford carried it over with the 7.3.
I have the 2024 GMC 3500HD gas, no complaints after 480 miles, but I would like a dipstick! I did have a recall for the aux battery that might not be charging, 3 hour software update done at the dealer yesterday.
I love the 10 speed on my 2024 L5P. Only weird thing is every time I underbody was my truck the check engine light comes on and then goes away. The duramax is great but unfortunately I had to have my EGR replaced at 9k miles and my tow mirrors replaced. Kinda leaning towards a Toyota tundra with the v6.
Consider a Titan XD vs the Tundra.
I had a 2006 8.1 with an Allison and it was junk, a slight grade 7500lb load it would over heat and cook it, last new gm product I ever bought.
Yup, I Lemon Lawed an '04 8.1/Ally that they could not make work right. Garbage.
So GM can't engineer a transmission (Allison), or their own diesel (Duramax aka Isuzu)...interesting.
The simple truth is if you tow a lot, diesel makes a lot of sense. If you tow in the summer a half dozen times a year, don’t be stupid and save the money. You might get your macho bragging rights, but you won’t win any smart awards.
I bought a zr2 2500 hd...it sucked I hated it ..traded it back and got a duramax one ton

Gm owns allison since 1928
They sold it in 2007
@taylorsvilletony773 didn't know that, what kills me when people ask if gm got Allison's stamp of approval when in all reality gm is allison or was for years!
The torqshift and Allison were not co-designed. Only the 10R80 and 10L80 used in half ton trucks were.

It’s based off the same platform. Very different end products don’t get me wrong but started with that joint venture.
I’ll never buy a motor with direct injection. Unless it’s dual injection like some of the Fords and Toyotas.
