I'm surprised it took this long for "il duce" to enact these regulations. I bought the Denali b/c I figured they were coming.

 

It'll be interesting to see if the automakers continue to spend the R&D dollars to produce high-powered trucks and suvs with the new gas-guzzler tax. Or will it be the 70s part deux...

Well where HD trucks are concerned, they HAVE to keep producing high-powered drivetrains for them. The nice part of that is higher efficiency can have a nice side effect in the form of more power, if implemented correctly. I think it's very much possible with modern technology (things that didn't exist in the 70s) to increase efficiency without decreasing power.

 

Too bad that all comes with a steep price tag attached to it. :D I don't think we'll ever see truly downright "cheap" vehicles of any kind for a long, long time.

:D

 

I think until some exotic fuel is discovered, the main stay will be factory turbo’s and maybe even the rebirth of a manual transmission. Just imagine a 6.2 twin turbo Silverado with a 6 speed manual transmission. Yeah I would hate to be forced into one of those

Not gonna happen. Again, with modern technology automatic transmissions have become just as if not more efficient and can shift faster than a manual transmission. Case in point, go look at the 0-60 times and 1/4 mile times of a manual transmission vs. automatic transmission in the new Camaro. The automatic is FASTER than the manual. That never used to happen, but now it does because automatic transmissions have drastically improved.

Maybe, but I would need to see the numbers, not that I would probably understand any of them, that they are more efficient than a direct drive manual tranny.

I understand a lot of guys on this site are "old school" or have mentalities that haven't changed from the "good 'ol days" (and trust me, that is frustrating sometimes when people assume any new technology is a bad thing or a sign that someone is out to get them) but seriously, this is 2010 now and vastly improved technologies DO exist.

 

Here's a case in point:

 

The V6 coupe will cover the quarter-mile in 14.5 seconds with an auto and 14.7 seconds with a manual, both at 97 mph.

 

Chevy's Camaro SS outfitted with the 422-hp 6.2-liter LS3 V8 six-speed manual hits 60 mph in 4.9 seconds and runs a 13.4-second quarter-mile at 108 mph according to Oppenheiser. Strangely enough, Oppenheiser also claims that the automatic-equipped SS Camaro, which is rated at 400 hp, runs from zero to 60 mph in just 4.6 seconds and through the quarter-mile in 13.3 seconds. "We optimized the shift points," he said.

 

So.... manual transmission gets more power and torque, but it's still slower which = less efficient.

That may have something to do with who is doing the shifting, I know for a fact that I can shift worlds better than my wife, but I'm sure that many other people can shift better than I can. Also isn't a manual more efficient than a automatic while coasting, something about no fuel or something like that?

Maybe they are afraid people will Bernstein The clutch!

:D I can see this is getting nowhere; I think you missed the part about giving up the old ways of thinking.

 

The only advantage to a fully manual transmission these days is the novelty and fun factor for drivers who know how to use them.

 

And "no fuel when coasting" with a manual? Umm... is the engine still running when you're coasting? If yes, then it's burning fuel.

So what new technology has the ability to double the combined mpg rating of these trucks in the next four to six years without a drastic reduction in horsepower? There's the simple matter of physicis. Without some totally new technology to make the truck lighter without compromising safety requirements and/or greatly advanced drivetrain technology, I just foresee smaller engines or gas-guzzler taxes.

 

Hybrid combustion/electric won't solve the issue. The hybrid Tahoe still only manages a combined twenty. And not only are the manufacturers haivng to try to drastically increase MPG they must also do it while having to conform to new BS emissions standards. GMs OHV engines could get one-to-two more MPG highway if they could use the lean cruise that they can in Australia but they're not allowed to b/c of NOx emissions.

 

Turbos aren't going to solve the problem entirely on their own either. I think we can all agree that the 3.5L Ford EcoBoost is a technological marvel. Yet it still only manages 17/25 in a car.

 

And all this has to be done without vast quantities of exotic materials. B/c I'm sure they could meet all the requirements today if we could all afford to buy six figure trucks.

 

Make no mistake about the intent of these new regulations. Their purpose is to change the behavior of the people in this country. Not to arbitrarily force the automakers to implement some new technology that they have locked away in a closet.

      primary drive belt tensioner

      By Deadwood · Posted

      I bought belts and pulleys for my '20 L5P at Rock Auto a couple years ago. I have used them for many years, and almost always save significant money, especially when I buy maintenance stuff ahead of time.   They carry many OEM parts, which is all I use unless an aftermarket is shown to be same/superior, or if it is an insignificant part or unavailable OEM part anywhere else. RA is usually lower priced, often by a bunch, but parts are sometimes unavailable or out of stock, and I do shop around and sometimes find better prices at other sites.   Be aware that you pay shipping, and if you buy multiple items and they are coming from different warehouses, the shipping can kill the advantage. Planning ahead is best if possible.   If you have a transmission service in the near future, check out their OEM (AC Delco ULV) fluid, usually MUCH less than anywhere else.

      10L1000 anyone with High Mileage ? I hate Damocles....

      By Deadwood · Posted

      New member here, very long time occasional guest. Saw this thread, thought it would be a good time to contribute someting. It is only my experience and not a claim that everyone will have the same.   I bought my '20 3500 L5P new and have put 99.9% (literally) of it's current ~400k miles on it myself, with over 50% of that towing loads between 4k to 15k, and to me this truck has been nothing short of amazing. For the first 235k I had zero issues, and from there until 321k I replaced a NOx sensor, two failing glow plugs, and three of the notorious injector connectors. I believe this truck is in part, a testament to good luck, but also good care and following a decent maintenance schedule (I also keep meticulous records.) As a result, it looks as good as a well cared for 70k rig, up and down, inside and out.   At some point before that 321k mile mark I began to get a little spooked about the 10L1000, especially the valve body. Word of mouth about potential issues prompted me to jump on the net to sift through all the noise and determine what all the fuss was about. I routinely take long trips, coast-to-coast and points in between, so roadside breakdowns can be '...a thousand miles from nowhere' and a bit of a challenge, and though I had no issues, my guard was up and activated.   And then I stumbled across a chance to salvage some parts off a new 2025 that had been wrecked in transport. I grabbed a few wear items (alternator, pulleys, etc.) and on a whim asked what the ten speeder would cost me. It was cheap...really cheap. I knew some changes had been made in the '24+ version 10L and were supposedly not compatible, but I called service/parts at my local Chevy dealer and asked why and they didn't know. A call to a well known aftermarket transmission outfit revealed it was very likely it would be fine, but to them not 100% sure.   Because it was cheap (really cheap) and I was spooked, I took the chance. Had it installed by a local shop and it worked like a champ, shifted just like the original. At it's first service at 37k, I had the shop put in a Next Gen valve body kit, which after some initial hiccups and rough shifts, smoothed out though with somewhat firmer shifting.   All that said, I have a very serious concern about my newer transmission as just two weeks ago it suddenly began to exhibit a strong reluctance to engage forward or reverse. It was a bit past due anyway so I took it in for service. The reason it was sticking was due to 'glitter' in the fluid clogging the filter...not good folks, often indicates a converter giving out. We ended up going ahead with the new filter and fluid, first to see if it would move and shift, and then if so buy me a little time. It did, and I've driven it over a thousand miles and it is shifting smooth, no noises or slipping. Regardless, it looks like a third gearbox is in my future so I can resume taking long trips with some confidence. In the very short term, my curiosity will have me examining the fluid to check how much glitter has reappeared.   An earlier poster had alleged, in the context of 10L100 failures, that it is another example of how we seasoned citizens somehow descend into hysteria, lose control of our senses, and react irrationally after brief encounters with the idiocy of the internet infosphere. Let me say (and I have used and abused said internet since it's infancy) there is no segment of the populace that has a corner on over-reaction to digital garbage. Just as my offering of experience in this arena is purely anecdotal and should not be considered gospel or all-encompassing, I believe it is still worthwhile information to consider, along with other relevant anecdotal experiences about things like complex transmissions, especially when balanced with other sources.   So to answer the original question, yes I got high miles out of my first 10L, trouble free for 321,000. Now I really wonder how much longer it would have went. Did I 'overreact' to the internet ghouls by replacing a 'good' one with a 'bad' one? Maybe. Who knows, the thing might have taken a puke a 100 miles later. So I'll just fix it again, then move on and start thinking about all the other stuff that will eventually wear out. It still has the original brakes (they're at ~60%), original injectors/pump, turbo, water pump, etc....pretty much original everything. Knock on wood.

      6 Speed vs 8 Speed

      By swathdiver · Posted

      At peak temperature.  They get to cool down and warm up more, especially those with the external cooler.  I have three GMT900s and one of them has over 225K on its original transmission.  Fluid gets changed about every 36K miles, all of it.     It's not the bean counters, it was the government.  They had to meet CAFE standards and other government requirements.   To get around that, we tune them and modify them to our liking.
