Great info! Surprising results. Would love to see compared to the 2500 with the new 6.6 gas engine.

Andre's Homer Simpson impression "Oooh power folding mirrors" had me on the floor.

Great video, especially since I just bought a new 2020 4x4 Silverado LT with the 5.3 L and the 8-speed (3.42 gears). I got 22.2 on a 24 mile hwy run at 68 MPH on cruise control.

I just purchased a 2019 Silverado 5.3 LTZ with 8 speed non Z71 with 22 inch rims and love it Thanks TFLT for all your info in your vids

Awesome video, love see chevrolet videos. My ‘14 Silverado 4X4, 5.3l & 6-speed Auto, still impresses me after 3 yrs of ownership and 160,000 miles later and still getting over 20 mpg on the highway. Love Chevrolet for Life. Thanks TFL.

Thanks for the video, I knew you guys would put the pedal to the metal. This video confirms my decision to pick the trail boss over the LTZ. Really enjoyed the video.

Although the 10-speed gives a mechanical advantage over the 8-speed, the increased frontal area, and higher coefficient of drag on the trail boss decreases its efficiency because it makes it less aerodynamic. Also, the duratracs have parasitic losses due to higher rolling resistance, in addition to the higher rotational inertia. This is why the LTZ is faster, and gets better fuel efficiency. The conclusion from this video should not be that the 8-speed is better than the 10-speed, it should be that the 10-speed is having to overcome a lot of disadvantages on the trail boss in order to make the truck perform better.

I missed the drag races, good job guys!

I am partial to victory red, same as my 06 Silverado reg cab short bed with (factory) v8 and manual transmission, and 3.23 gears... and I still get 17mpg city without any of the cylinder deactivation or other fancy technology bits, thanks to the 4200 lb curb weight and manual transmission.

Wow the powerfold mirrors are amazing! My 07 f150 has that with autodimming

Awesome Stuff Guys! Hoping to see a Silverado Trail Boss 5.3L V8 10-Speed VS F-150 FX4 5.0L Coyote V8 10-Speed in the Future.

Trail Boss looks very aggressive. I like it! In Italy the Trail Boss is imported and costs € 63.000 , about $ 68.000

Cool video. Wonder how the six speed in the 2018 model do against these two. Would be good to know the suttle differences.

I know there's a lawsuit on the 8 speed but there is a lot of people that like the 8 speed. Also I've heard that people say when they deactivate the amf/dfm the transmissions shift better. Makes me wonder if the maybe there isn't so much of a problem with the transmission but maybe it's the cylinder deactivation that's causing the issues. 🤔 Has anyone else heard of this?

Both are adequately fast. Fun video though. I know that someone mentioned more gears takes more time to shift but really these were probably both only in 2nd gear by the end of that race. I wonder if the lift may have had something to do with it. Taller truck may take more time for weight to transfer on hookup? IDK results are certainly not what I would have expected. Maybe the computer in the 10 speed is pulling power in 1st gear to protect it?

Chevy baby! Thanks guys. Great vid. ☘️

be interesting to see one of these trucks go around the track, curious if it's as bad as we think it'll be

Haha "expensive cameras flying" lol good video guys

Another life lesson where I think the bigger number is the best option and find out it's not what I thought it was... still learning this over and over again.

This is a very good comparison. I just recently traded my 2019 Ram Rebel after 2 years for the GMC Sierra AT4. While I still feel my Ram Rebel was hands down far superior in interior fit/finish/materials, electronic functions (driver display center, and UConnect system), and just about every feature of the interior, ride quality was also superior. But I was still very unhappy with Fiat/Chrysler for misleading fuel economy figures of the Ram Rebel. I drive from Florida to the midwest multiple times per year and the Rebel's fuel economy was absolutely dismal. The AT4 I purchased is loaded. The fuel economy was spot on what I expected and averages 3-5 mpg higher than the Rebel. As for your test results, I believe the tires are more to blame. My AT4 came with the 20" tires, but I did not want to pay the $899 for them so I had to wait till the dealer got the 18" Duratracs in. I drove 2 tanks of gas with the 20's before installation of the the 18" Duratracs were complete. Mileage dropped 1.5 mpg. So overcoming the beefy tread of the Duratracs takes away from both performance and economy.

Now do the TB vs the AT4!

I have the GMC version and those duratrac tires are extremely loud on the road and when i switched over to a BF KO's i notice a big fuel economy jump also.

Pretty surprised by the results as the LTZ has to be heavier and with the 8spd. But I guess the extra height and off road tires really do make a difference.

Both awesome trucks... great video

I asked Chevy why you could not get a Trail Boss in LTZ trim at on the inside. Needless to say I haven ' theard back from them! Great job guys on these tests . These two models are the finalists for my next truck!

"Expensive cameras flying" Hoo man, I know that feeling. I've broken a DSLR lens that way.

Pretty crazy that you CANT get a 10 speed in the LTZ. They must want him to get the 6.2 or the diesel

I’d like to see a highway mpg loop see what they are getting when just cruising

Can you guys also do this with the new 6.6 gas & duramax? Would be sweet

One thing he didn't mention about the Z71 package I found while shopping for a Chevy truck- Without Z71 you only get a one speed transfer case- that's right no 4Lo, only a terrain control which is an electronic crutch that uses traction control like braking to "pop" you out of a rut by essentially torque braking! So far Silverado is the only full size 4WD to not give you a 4 Lo- I guess they want to make a few hundred more dollars per unit hoping no one notices!!!

Wow! I seen the video was over 14 minutes long and though to myself, they filmed the entire 1/4 mile race...

Those Silverados scream "In your face!"

This was shown when the camaro went from the 8 speed to the 10 speed too. The times were exactly the same. But I would never get the gm 8 speed. So many problems. The 10r80 is still superior.

I'd buy a dark blue RST z71 Silverado right now if there were any in stock in my area. This video just decided me over the trailboss. gas mileage and 0-60 speed. been waiting on this comparison for a while.

Great video! If it were all about drag strip times we’d all be driving 6.2’s or Ecoboost’s my lil 2.7 Ecoboost will leave a 5.3 sitting, but which engine is capable of 300k, I’m hoping my lil engine will get there, but I have friends with 300k on their 5.3’s. My truck has a lowly 6 speed and I like that, honestly talking to other 2.7 owners with the 10 speed my truck gets better fuel economy, but I’m older and wanting the truck to go 300k+. Wondering if you’d put Big Daddy Nathan 1/4 Miler in the 10 speed would it had made a difference? Still awesome video!!!

I want to see a drag race between 2 more chevys same truck same motor but with different transmissions just to see if the 10 speed is that much better

Trailboss 32.1" tires with the 18" wheels. (275/65 R18) LTZ 33" tires with 20" wheels. (275/60 R20) That means the trailboss has a gearing advantage with the smaller diameter tires. That combined with the 10-speed. If both trucks had 35" tires or larger then the advantage of the 10-speed would be more noticeable. 10 gears gives you more headroom to throw on larger tires without having to change the rear end ratio to compensate. I think that's why they slapped the 10-speed on the Trailboss.

Im swapping l83 5.3 in my 80 cutlass supreme its a 6speed planning on racing hope I win alot of races 🏁 going to make a KZfaq channel showing my results

I don't like chrome either, but that LTZ is so luxurious. I'd have to go with that. My mother in law has one and I'm always looking for a reason to borrow it.

Would like to see this done with the new Range DFM disabler (full V8 all the time). My '19 Z71 drives so much better now. I took the hidious air dam off in about 15 minutes.

Its the heavier tires on the trail boss for sure. More Rotating mass will surely kill acceleration and efficiency. Good video. Oh and Thank you for saying "pounds-ft" and not "foot-pounds".

Shows the extra gears are mostly to get a bump in fuel economy and emissions ratings and maybe more pleasant towing, not necessarily for speed

I have a high country with 10 speed love it

I don't go off road so the "Silver"- ado is for me.

I’ll say it. My 2014 was and still is a fun truck to drive. From stock it topped out at 110 but for some reason my brothers 2020 Silverado tops out at 95. Now I have lots of work put into it and tops out at 160, 140 on the dash but in the display it will show you how much faster your actually going than the needle gauges. Idk if that can be done on the newer 2020s 🤷🏻‍♂️

I'd bet money the difference is in the torque converter tune. The 10speed is tuned for economy so the torque converter probably isn't going to be as aggressive with stall speeds. Even though the 10 speed's first gear 4.70 is slightly shorter than the 8 speed's 4.56, a higher torque converter stall and more aggressive ramp up would make the 8 speed quicker off the line.

5:52 Your welcome

Silverado wins !!!

Andre. Fun video. Just a nit, the differential ratio is the same front and rear. If you can’t open and close your tailgate you should be driving a Honda

I love these trucks. Very interesting stuff.

I’m currently driving a Charger Scat Pack with close to 500 HP, and I’m seriously considering a TB. I don’t know why I’m worried about a reduction in HP with a truck. When I drove a 2010 Silverado LT with 310 HP, I thought it flew so I imagine the TB is a huge lighter upgrade

Very interesting. Just curious, did you guys use same octane gas?

It'a probably too late to test, but what would be interesting is to change the tires and wheels from one truck to the other and then run them again. You may find it is all in the tires.

Great video!, any chance you can race the half tons against the midsize class at some point or is that sac religious?? 😁. I feel like the Chevy Colorado could hang with these two trucks 0-60 at your local track? 🤷🏼‍♂️, Thanks

10 speed is efficient yes but when it comes to acceleration of course it while lose because it has to shift alot of times to speed up. I think difference will become apparent in towing heavy loads thats is why semi truck even have more than 10 gears.

I think 6-8 speeds is enough, on my F-150 I think 10 speeds is too much. The 6 speed in my Lincoln is perfect for acceleration off the line and for low revs on the highway.

Can we get the trail boss vs Ford F250 7.3 V8 drag race

Is the Canadian guy with the beard still part of the team ? Have not seen him for a while on your channel

I'm going to be one that complains that not everything is matched. Tires can make a difference and your MPG shows this at the end. As for which I would take it would depend on what I am buying it for. If I plan on using mainly on the highway it would be the Zed if using offroad it would be the Trail Boss.

Project truck? What projects have you done to the TB since you bought it 3-4 months ago?

Same 3.23 gears but taller/heavier tires on Trail Boss makes it accelerate slower, even with 10-speed. Needs a 3.42 or even better, a 3.73. And, might as well throw in the 6.2L too. 😆.

Let's see a 2018 Sierra Denali 6.2 vs 2019 or 2020 Sierra Denali performance and MPG review!!

I am a big fan of the Silverados but I have to take issue with those gill plates on the front side of each fender. In the winter time filthy salt spray from winter driving on slushy freeways builds up in those slats. When the temperature drops below 20 it would take you $10.00 in quarters to try and clean the dirty ice out of there at the spray wash. Even in the summer it seems as if they are dirt traps that are difficult to clean.

Nice could guys do the 2020 GMC Denali sierra vs 2020 AT4

What beautiful trucks!!

Would have thought the 10 spd had advantage, but tire weight, tire height impacts gear ratio some. As for looks, I still like to see some chrome, the silver truck looks classy, but some like blacked out look.

Very surprising results honestly especially considering the LTZ has taller gearing with the 8 speed and even has taller tires to boot. Assuming the LTZ has 275/60/20, that's a 32.9" tire and the trailboss has 275/65/18, thats a 32.1" tire. 8L90 1st gear ratio is 4.56 10L90 1st gear ratio is 4.70 I'm assuming both trucks are 3.23 rear end Maybe the silver truck is just a factory freak lol

Can you guys get Into suspension optionsand what they mean? I have a z85 suspension on my 2004 3/4 ton sierra which rides smooth for a 3/4 hd and it's smoother than my dad's 1/2 ton with z71. I've looked up z85 and can't find a clear answer. Some say it's shocks others say level kit or body lift to.

10 speed might still be quicker than the 8 speed. you might see the 0.4sec difference just in tires and the lift

Should’ve thrown in a 5.3 6-speed just for shits and giggles.

I haven't met too many people who are happy with that 8 speed. I'm sure there are some, but I haven't seen it.

It was a great test. Definitely chevy guys out there deciding which $55k truck they will buy.

Next time do a Custom crew cab short bed with the Custom Value Package (in black) vs a Custom Trail Boss crew cab standard bed with the Dark Essentials package (in red). That’s what we want to see.

No surprise. The Less shifts the more power you get from engine on every gear on good transmission. There is a reason drag cars have a 2 speed transmission in most cases.

I wouldn't worry about difference between 8-10 speeds. It will never be as big as going from 4 speed to 6 and even 6 to 8. This race would be interesting with a trailer.

I like LTZ its has so chroms on the front, and if its come with 6.2 L it's will be really incredible!!!

Drag the 2020 2500 HD with the 6.6L gas engine against the 1500.

I have the 8 speed RST and it’s pretty fast 💨 and could tow 9800

I'd like to see you swap wheels and tires between the trucks and see what they do. I'll bet that is the difference more so than the transmissions. Off road tires kill 0-60 and mpg.

Hello tfl can do test the 2020 Silverado 1500 high country with the 5.3l v8 and 10 speed automatic transmission because I would like to see you test the that truck with many tests.

At 9:01 seconds Andres upper lip action he felt bad ass lol

I removed the air dam on my silver LTZ, and my God! What a difference. No change in MPG at all. And I'm supprised you found an LTZ without the Bose speakers. You got ripped off on that.

Question ... How did you get the front lights to strobe ?

Can we see a drag race with 5.3 ecotech 6 speed transmission vs the 5.4 ecotech 8 speed transmission

Takes time to shift. More gears MORE TIME!! Why do you think two speed powerglides are really good drag race transmissions!!

What is the weight of the 18” rims & tires vs. the 20”? That unsprung rotational mass might be your difference.

Should of done custom trail boss 6 speed vs the LT trail boss with the 10 speed

I wish you'd comment on the refinement around town between the two transmissions. The 8 speed has a lot of people who dislike it's shift logic and clunkiness.

I'd get the Z71 Silverado, both are nice trucks rather have chrome grill instead black mesh grill.

Why don't they do electrical deployment of the chin spoiler. Something that you can move up and down from the cab.

I put an intake, exhaust, and king 2.5’s on mine and it is a different truck let me tell you. I have the 8 spd and it’s really quick for a big truck.

So what are the differences between Z71 and trailboss? Spacer lifts?

So if you order the truck with the performance exhaust which is 13hp gain and the intake whick is 12hp gain and you get the e85 engine that give's you 405hp on e85 and 420 pounds of torque Road in My buddie's gave a 5.0 a nice gap even though his ford was lighter js spec the 5.3 rigt and you get a decent motor rather then it being the slowest in the segment look up the e85 5.3 alot more power.

I bought the LTZ 2019 with the 8 speed. I was a little irritated when they started putting the 10 speed in the Trail Boss. Now I know that Chevy had to go with a 10 speed for marketing prowess. I love my LTZ And I can put the Trail Boss factory lift on it if I want for just $1400. And I have all the LTZ stuff. Also LTZ has power passenger seat. I use the folding mirrors daily.

How do you make the lights do that

Any issues with the Silverado lifters?

Do the lifters still fail in the 5.3 I want to buy one but scared lol

I'd love to see a 6 spd version as well as the classic 4 spd 4l60/5e as well... get em all in there... I haven't even entered into the 07+ realm yet.. love my 01-06 era trucks. Just the perfect era with all of the modern amenities... literally, every single one of them that the new trucks offer.... every... single... one.... but can be had for actual fair prices, rather than 100% BS mortgage level crap. But I digress.... I'd love a larger comparison here.... 4spd, 6spd, 8spd, and 10spd... I also really wonder how these new transmissions are going to be holding up in 10 to 20 years... Any given Chevy truck from 1990-2006 can basically still be 100% rock solid. With predictable service intervals... Transmission will either last forever, or will need to be addressed between 175k-240k, or earlier if the previous owner was a pure piece of crap and beat the hell out of it, not knowing how to drive or use mechanical items properly. .. ... But those trucks will basically go, at least, to 250k... and if you even try the tiniest bit, you will likely goto 400k or more.... with all the new shit they are tossing in now, I have to wonder... we already so the DOD fail miserably, and they still toy with that shit. I just wonder how these unproven transmissions will hold... I mean, can't be any worse than Ford or Dodge's reputations... legit, earned, poor reputations... so there's that. Just gotta wait and see I guess.

I have driven both and I would take the LTZ, but don't care for all the chrome. Also for been so different they were not that far apart in performance.

Any desires to go off black top would easily be handled by the LTZ without the Z71 package so that’s the way I’d go every time plus I prefer the chrome on these trucks
