DISAPPOINTING 2019 Chevy Powertrain / Gearing options

The 3.08's are not standard gears for a K2 truck. 3.42's were and many trucks on dealer lots were "upgraded" with the "All-Star Package" that (in fine print) replaced the 3.42's with 3.08's. There were a LOT of guys that bought a basic LT Silverado 1500 without realizing that the all-star package meant 3.08's replaced the standard gearset.

Provide a link if you want to claim that the 5.3 with the 8L90 and 3.42's was the max towing package. I provided a link directly from GM's website that stated CLEARLY that the 2018 Silverado 1500's max tow package was the 6L80 with 3.73's. The 8L90+3.42's "max trailering" only exists if you buy a CC LTZ with the 5.3, pay to upgrade to the 8L90, then pay for the 8L90 version of the max trailering package, which then gives you 3.42's. You can't get that combination in any extended cab regardless of trim and you can't get it in an LT trim. Any of those configurations only let you chose the 6L90+3.73's as the "max trailering" package. Even if you build a CC Silverado 1500 LTZ with the 5.3, there's a 6L80+3.73 "max tow" package.

I guess you should check your facts?

It's not as though the troll above didn't earn the names he was called. It's pretty obvious that he registered here only to stir crap up. GM-trucks is one of the few web forums that actively seems to invite trolls to register and spam these forums just stir stuff up. If he had registered at Tacomaworld or Ford-trucks.com, he would have been permanently banned and this thread would have been locked instantly.

But is the 5.3 weaker? Look at the link I posted above. Somehow a 2016 Silverado 1500 with the 5.3, 8L90, and 3.42's was faster in the quarter mile, both when empty and when loaded with 1750 lbs in the bed, than a "more powerful" Ram 1500 with a "better" 8-speed and "better" 3.92 gears. The 2019 Silverado and 2019 Ram both have the same power as they did in 2016, but the Silverado/Sierra lost twice as much weight as the 2019 Ram did, and now gets the 8-speed standard, plus you can still get the 3.42's if you plan on using your truck to tow. So the Silverado/Sierra will only be faster than before, regardless of what the power numbers would suggest. The real disappointment is that the Ram barely lost any weight and the engine is the exact same ancient 5.7 that they were using in the Ram back in 2010. The fuel economy is the exact same as it was in 2014 but now the Ram has an air dam that's class leading in how low to the ground it is.

Did you have the all-star package? Because if you look at the window sticker it probably said 3.42's were standard, but then somewhere further down in the specs, a package that was added to the truck deleted the standard 3.42's and replaced them with 3.08's. There were a LOT of guys that saw 3.42's in the standard equipment list and didn't notice that they were replaced by some other package included with the truck. And at least most of the gear ratios are available in trucks on the lot. I checked and I can't find a single 2019 Ram with 3.92's on the dealer lots. All the 5.7 trucks have 3.21's standard. Ford is beginning to sneak 3.15's and 3.31's in new F-150's. Ford actually lists 3.15's, 3.31's and 3.55's all as the "standard" gearsets. 3.73's are extremely rare in an F-150 today. Most are in F-150 XL trims meant for fleets, not for consumers. You would have to special order that combo in an F-150 to have a truck with a decent interior and features. And anybody that has been in a 2018 F-150 with the 10-speed and 3.73's can tell you that while it's awesome that you can roast the tires from a stop on command, the gears are just ignorant for most real world truck usage. Unless you like burning up $800-1000 in tires every other year and like having the traction control constantly going off in rainy or winter conditions... From a practicality stand point, with 32 or 33" tires, the 8-speed or 10-speed matched up to 3.42's or 3.55's is more than enough gearing. I'm just glad that it looks like the 3.08's are going away for now.

So you admit the 5.3 8 speed non max tow was 3.42 but don't believe the max tow was too? What do you think it was?

Like I said, in 16 all SLT / LTZ 5.3 trucks had a 8 speed and 3.42 gears, crew or double. 2wd or 4wd. Mid year they started restricting the 8 speed more and more.

3.08 gears are garbage. As I've said before, the 8 speed 3.23s are just fine. I just want a 3.42 option outside max tow. Or let any truck get Max tow.

It's not asking for much. It's BS the 5.3 isn't getting the 10 speed. I thought GM could grab some market share back with these trucks but it's clear that's not a priority.

cr250Silverado · June 18, 2018

To be clear I take responsibility for not doing my homework. My truck does have the All Star Package, however looking at the details on the Chevrolet website it does not specify such a package replaces 3.42s with 3.08s. And YES on my window sticker the left side lists 3.42 (*but* states it comes standard with the V6, not the 5.3), then on the right side it has 3.08.

After learning this (after buying) I went onto my computer and when I configured a 1500 online it defaulted to the 3.08 gears, but YES I could have clicked the box and easily changed it to 3.42 for no charge, however doesn't that make the 3.08 gears standard if it auto defaults to them? Looking at multiple dealers since I'd roughly say 80% of their trucks (non max tow package) come with 3.08s. Therefore I have a hard time believing 3.42 are "standard" on 5.3 6pd 1500 pickups. I have no literature to back up my side, or to convert me to believing 3.42s are "standard." Either way it doesn't matter to me what is "standard," what I am interested in is why GM created an "upgraded" V8 package and equipped the trucks with really good tow features (hitch, harness, 7pin, etc) yet these trucks tow worse than the standard (cheaper) V6 motor.

Don't get me wrong I have always been a Chevy guy, I love their value and overall package. I made clear statements it was my fault for not doing my full homework, but as a guy going to buy a full size pickup from a major dealer I walked in with a higher level of trust that GM would configure their trucks in a way that makes sense. What is the purpose of the 5.3/3.08 package over the V6/3.42? What crowd does it cater to? What was GM's intentions behind the vehicle when compared to their V6/3.42 (standard)?

With all this said I feel I got a good deal, 37,200 (plus T&T) 18 CC 4wd 5.3 6sp LT Z71 All Star Bose trailer package

A LOT of guys made that mistake. The window sticker is really misleading unless you stop and read everything they packed onto that page. For a guy that owned a GMT900 or worse a GMT800 Silverado, driving a 2014 truck with a much more powerful 5.3 wouldn't necessarily notice that the truck had 3.08's instead of 3.42's without hooking up to something.

The 6L80+3.08's package was meant to improve CAFE averages. For the guy that drives a truck but doesn't tow much more than a small trailer or boat, the 3.08's work okay. A large portion of people buying fullsize trucks today don't tow anything at all and really don't need an aggressively geared truck that's just going to get worse fuel economy. GM should make it more obvious on their window stickers just what equipment is actually on the truck.

When I use their build & price page, it defaults to the 3.42's when I chose to make a 4x4 LT Z71 with the 5.3.

Fortunately for me I fall into the category of currently owning no trailer, but with plans on a ski boat (3k + trailer), which the 3.08s can tow just fine. I have a good grasp on the whole CAFE thing, but I would imagine the V6/3.42 has better CAFE ratings than the 5.3/3.08, and it has a better tow rating as well.

You bring up a good point about older vehicles as the 14 5.3 6spd 3.08 was quicker than the 10 5.3 6spd 3.42.

I don't admit anything. And that wasn't what you said. This is what you said:

"Sorry guy but you're mistaken. With the 2016-2018 you could get the 8 speed with the 5.3. At first it was all SLT/LTZ trucks but they pulled it back to only higher optioned SLT and LTZs."

Which was your reply to my statement that the 6L80+3.73's was the "max trailering" package, which it is in every configuration unless you are ordering a CC LTZ/SLT 5.3 truck AND upgrade to the 8-speed. GM would let you build a CC LTZ/SLT with the 5.3 and it would default to the 6L80, and if you then chose the "max trailering" option, all they would do is change the axle ratio from 3.42 to 3.73. This is backed up by what GM says it is in the screenshots I posted. It's the max trailering package for any LT trim and it's the max trailering package for any extended cab LTZ. Even in a CC LTZ, GM says the max trailering package is the 6L80+3.73's UNLESS you pay to upgrade to the 8L90. Then and only then would the "max trailering" package give you an 8L90+3.42's. One cab configuration, in one trim, with the upgraded transmission. And the tow rating for the 8L90+3.42's is exactly the same as the 6L80+3.73's.

Man, I don't know how else to tell you you're wrong. Read it again. Like I said, 2x, it was all SLT and LTZ 5.3 in 2016 trucks and then they started limiting it. Your response it to post a 2018 availability BUT THAT'S AFTER THEY REDUCED THE 8 SPEED AVAILABILITY(like I said they did).

Please understand what you read before you respond to it.

Yep. That's how I didn't notice it. I scanned to the window sticker too fast, saw 3.42's on the left hand side, took the truck for a drive and it was definitely faster than my buddy's 2011 Sierra 5.3 which I knew had 3.42's, so I assumed the truck was good to go. It wasn't until I saw a post on here a few months later that I realized it was a 3.08 truck.

Who the cares what you could order in 2016 for a little while? He was talking about the 2018 truck. We're discussing the changes in axle and transmission options for a 2019 truck compared to the truck it's replacing, which is a 2018 Silverado/Sierra. What you could order in 2016 is irrelevant. For all intended purposes, the max tow package was the 6L80+3.73's. I don't care what GM offered in 2016. I don't care what they offered in 2017. 3737 was talking about 2018 and using that to try to make his case that GM is gearing all their trucks taller.

_____________________________________________________________________________________________________________

So as I was saying. 3737 is complaining about GM making the gearing "taller" for 2019. The fact of the matter is that the 2018 truck's standard trans and axle ratio was the 6L80+3.42's. The new standard trans and axle is the 8L90+3.23's. He's so hyperfocused on the axle ratio being 3.23 instead of 3.42 that he can't process the concept that the 8L90+3.23's has a better final drive in every single gear compared to the 6L80+3.42 combo. Just look at the final drive ratios ExFordGuy posted -- the 8L90+3.23's is actually closer to the 6L80+3.73's than it is the 6L80+3.42's. Yes, that's right. The standard trans+axle ratio for the 2019 GM trucks is pretty much the same as the 6-speed "max tow" package available in 2018. Which is why I pointed out that most guys with 33's aren't complaining about not having enough gear when they have the 6-speed and 3.73's. A truck with the 6L80 and 4.10's is almost overkill with 33's. When you're cruising the interstate at 80 MPH, the engine is screaming at over 2000 RPM in 6th gear with that setup.

3737 also complained that GM is now making you get the max tow package in order to get the 5.3+8L90+3.42. That's technically no different than it was with the 2018 Silverado. If you wanted the 5.3, 8-speed, and 3.42 gears, you had to choose the 8L90+3.42 "max trailering package". The standard max trailering package in 2018 was the 6L80+3.73. He's complaining that the 3.73 is going away, which is all due to the fact that the 6L80 that it was matched with is also going away. The 8L90+3.42's has far better final drive ratios than the 6L80+3.73's, so who cares if the 3.73's are gone. The final drive is still better in every gear. And it's not like you couldn't regear the truck some day if you really thought you needed a 3.73's with the 8L90. None of these manufacturers are worried about the guy trying to lift his truck and put 35's on it when they decide which axle ratios they're going to offer.

So the standard trans+axle ratio and max towing trans+axle ratio are both improved for 2019. PLUS the horrible 3.08 axle ratio appears to be gone too. It sucks that the max tow package's 3.42's can't be matched with the Trailboss or Z71. Who knows, maybe GM is leaving that open for a ZR2 Silverado (http://gmauthority.com/blog/2018/06/this-is-how-a-2019-silverado-zr2-could-look-like/), but if it's that big of a deal that your Z71 or Trailboss have 3.73's or 4.10's, regear it and move on. ECGS has 5.38's for the GM 9.5" 12-bolt. With 35" tires and 5.38's the 8-speed would probably shift at least 3 times by the time you hit 15 MPH and 6 times by the time you hit 35 MPH. Even with 3.73's and 33" tires, the 8-speed would shift 5 times by the time you hit 35 MPH.

Sure, you can technically get an F-150 with the 10-speed and 3.73's, but you'll never find one on a dealer lot. I searched the 5 closest Ford dealers and the vast majority came with 3.31's and a few with 3.55's. Not a single 2018 F-150 10R90+3.73 in inventory. The only way you're going to get that combo is if you're very lucky or you special order it, which often means you're usually not going to get the same incentives that you would have gotten purchasing a truck on the lot. Same with having a dealer search for the truck you want and getting it from a different dealer.

Unless you’re towing in the upper levels of your trucks limits most people wouldn’t be able to tell the difference between the gears offered if they didn’t see it in writing. As far as performance it’s has been a long time since I had to mat it to get up to speed or merge in traffic. All this complaining about what the other guys offer, that’s easy buy it. I bought a 95 V10 Ram for pulling in 95 I didn’t like gear so I changed it. Most of my trucks back in the day I thought was under powered, I modified them. I’m like a kid in a candy store these days almost any vehicles has good performance. My biggest complaint they want to make a V8 run on 4cylinders. Just when they got them to easily run past 200K miles.

Here it is again….couldn’t be more clear.

2018 5.3L 8 Speed had 3.42 gears STANDARD, No 3.23

2019 5.3L 8 Speed has 3.23 gears standard

MOVING TO TALLER STANDARD GEARS!!!!!!

Lots of dealers have Raptors with standard 10 speed and 4.10 gears, they are not hard to come by. They are geared for performance, right from the factory, which is nice and a requirement to earn my money. They drive just fine on the highway, the 10 speed has 3 overdrives, THREE OVERDRIVES!!!!!!

I thought the Trailboss was going to be a performance model. GM is all about building a truck for everyone, with all of these models and configurations. Why not a model that is built for performance? Why limit the Trailboss to the tallest gearing of all the 2019 trucks? Wouldn’t this be the model to offer lower gearing in? Yet it can’t even be ordered with the Max tow package because that can only be ordered with a single speed transfer case. WTF!!!

I thought the Trailboss would have the 10 Speed and 3.42 standard and maybe this being GMs factory lifted truck, they would get wild and crazy and offer a 10 speed 3.73. It still wouldn’t be a Raptor but it would be a legit truck

ChuckTuna · June 19, 2018

I had written a long post describing why I feel like the axle ratios they are using are geared toward the Trailboss custom but I think I understand your gripe 3737. The axle ratios work out perfectly for the Trailboss if you want to upgrade the standard 33" tires to 35s with the 3.42 axle (3.425 is the actual math for the 35" tires). Of course this all relies on the 35" tires fitting in the wells after upgrading to the 3.42. You seem to want more off road capability and less fuel efficiency since it is the Trailboss which indicates to me it is for people who like 4x4ing and aren't as concerned with fuel economy. I hope that Chevy intends to make up for your lack of power with the 5.3L v8 6 speed they offer in the truck.

MOVING TO TALLER STANDARD GEARS!!!!!!

I don't know how I can make it any more clear for you.

In 2018, the 5.3 8-speed had 3.42's because it was A MAX TRAILERING PACKAGE.

In 2019, the 5.3 8-speed with 3.42's is the MAX TRAILERING PACKAGE.

The gearing did not get taller because the 5.3+8L90+3.42's was a max trailering package in 2018 and in 2019.

GM DID NOT HAVE a "STANDARD" 5.3 + 8-speed package. The only package in the 2018 Silverado with the 5.3 that GM called "standard" was the 6-speed with 3.42's. The 6-speed + 3.42's was replaced for 2019 with the 5.3+8-spedd+3.23's, which have bettering gearing than the 6-speed and 3.42's. Like I said, the 8-speed with 3.23's will turn 33's easier than the 6-speed and 3.42's. It'll even turn big tires easier than the 6-speed and 3.73's can.

So, do you not understand the concept that the 8-speed with 3.23's can turn big tires easier than the 6-speed with 3.73's could? Because the post by ExFordGuy layed it all out for you. The 8L90, turning 3.23's, has a better mechanical advantage in every gear from 2nd through 8th. And the difference in 1st is so small nobody would be able to tell in a blind test.

The engine will have an easier time turning the wheels when connected to the 8-speed and 3.23's than the 6-speed did with 3.73's.

Whether the Raptor comes with 4.10's or not is irrelevant. GM hasn't come out with a truck meant to be a Raptor fighter. The Trailboss isn't mean to be a Raptor fighter. For the $60k+ a new Raptor will cost you, you could buy an LT Trailboss, pay to regear it to whatever gear your heart desires up to and including 5.38's, lift it, put big 35" tires on it, and STILL have money left.

GM doesn't have a truck that has 35's that would need 3.73's or 4.10's. Even Ford doesn't sell a regular F-150 with 4.10's. They don't build F-150's with 3.73's to fill dealer lots. Dealers don't order F-150's with 3.73's to stock dealer lots. The highest gear ratio they put in trucks destined for dealer lots is 3.55's.

Not one of the truck manufacturers is building half-tons thinking "we need to spend a ton of money so we can manufacture another axle ratio for the guys that want to void their warranty by modifying their truck with an aftermarket lift and huge 38" tires". If you want to void your warranty by installing oversized tires and a big lift, its on YOU, NOT the manufacturer, to regear your axles to compensate for it. Ford doesn't do it. Ram doesn't do it. GM doesn't do it. Not even Toyota does it (no, those 4.30's will not turn 35" or 38" tires well, not with the gearing in the AB60E).

5.3 8 speed was 3.42 STANDARD and MAX TOW. Can you not read????? I have told you this 3 times now.

I JUST BUILT A GMC Sierra All Terrain with 8 speed and 3.42 gears on GMC.com. No max tow.

You can not get the 5.3 with a 8 speed in 2016 to 2018 without getting 3.42 gears, max tow or not. Not any year, not any trim. 8 speed 5.3 means 3.42, PERIOD.

That's because the ONLY way they sell you a 5.3 + 8-speed is by forcing you to chose the MAX TRAILERING PACKAGE. Just because that's the only way you can get a 5.3 with an 8L90 doesn't change the fact that it's the F*CKING "Max Trailering Package"

If you don't check that box and continue on, they remove the 8-speed and replace it with a 6-speed and tell you to choose the "MAX TRAILERING PACKAGE" if you still want the 5.3 and 8-speed.

No f*cking kidding genius. The only way GM sells you a 5.3 with an 8-speed is by selling your the 8L90+3.42's, which they universally refer to as a god damn max tow package. Just because the Build and Price defaults to 3.42's when you select a 5.3 and 8-speed, doesn't change the fact that in all of their documentation, they refer to the 5.3+8L90+3.42 as a max tow package. THERE IS NO "STANDARD" 5.3+8-speed+axle ratio package.

That's no different than how they handle the 6.2, you are automatically defaulted to the 8-speed and 3.23's. GM universally refers to the 6.2 + 8L90 +3.23's as a "max trailering package", even if it's a default combination. They don't call the 8L90 + 3.23's the "standard" package with the 6.2. It's listed as the "6.2L V8 with Max Trailering Package". NOT "6.2L V8 with standard axle ratio package", even though that's the only option you have.
