Crew cab 4x4 5.3 3:08 gears

 

 

 

Kind of hard to watch :-(

keep in mind this is an extreme towing test

 

  • at max tow ratings (3:08 gears) when you add in passengers
  • towing up at least 7% grade
  • towing at altitude where you loose up to 30% hp / torque

Hardly hard to watch. You take the highest ratio GM offers with a mid lime motor and pit against Ford's best motor for the test with 3.73s and the Tundra with 4.30s and I'd say it did pretty good. Plus, while I haven't watched their other tests I think they really hurt the time by trying to keep RPMs down so the truck loses speed.

 

 

But damn is that a sweet sounding exhaust note! I may not have to buy an exhaust system when I get mine.

They did say that truck configuration was the only one they could get from GM. Maybe next time they can test a 5.3 with 3:42 or like you said (and they mention in the video) 6.2 and 3:73

 

As far as keeping the RPM's down thats the fault of the 3:08S. They were not exceeding the 60 mph speed limit and leaving the shifting up to the truck like all the other tests. :-)

This is a true showing of what rear end gears can do - people watching and posting in the thread on rear end gears and wheel/tire combos.

 

I have noticed when trying to configure these trucks - you can't seem to get the z71 stuff and towing stuff - like the larger mirrors.

 

I would like to see the 3.73 gear set with the 5.3 - that would really put that engine in a sweet spot RPM wise.

 

I currently tow a 6000 lb Travel Trailer with my 2500HD 6.0L 6sp 4.10 gears - I love to climb hills in 4th gear - 3500 RPM 55 MPH.

I posted this in the thread about the gears about the same time he posted this. The dude claiming that the 3.08 gears were perfect for this truck made me lol

agreed... stupid that they would bring a truck with 3.08's....... they make 3.42's an option for a reason

Thanks for the clarification, I didn't realize they had a set speed in mind. I realize its an attempt at consistency but they were being passed left and right at that speed and what I've done before when driving even regular cars that were gutless in the mountains was leave it in highest gear that was still responsive and let the engine scream. Modern cars and trucks aren't going to get damaged by that and especially these trucks seem to have excellent cooling systems so overheating shouldn't be a concern.

I have not seen the other videos either - but I wonder how close to Max they ran the other trucks - The poor Chevy was probably right at its CGWR - were the other's that close.

 

I am glad that they admitted that this was not the preferred way to do the test and that they really could not compare the trucks under load.

 

I would like to see the same test with either the 5.3 /w/ 3.73 or perhaps the 6.2 with 3.42

You're not going to lose 30% power up high. I've had my 2006 9k+ feet, and the power loss isn't even noticable. Modern engines don't care.

I bet the results would be different if they rerun the test when the NHT package is available, with both the 5.3 and the 6.2.

Holy moly that truck was suffering with that axle ratio. GM are shooting themselves in the foot by allowing the press to use these weak axles, because even if they do inform us of it in the video, the general population doesn't acknowledge it and thinks that GM can't tow.

 

They should have put a lot of effort into having the 3.73 or lower ready for early press tests such as these. Everything that has been done in previous videos has been a walk in the park and the 3.08 was good enough.

 

And I can't stand tests with different engines, axle ratios, cab configurations, tires, etc. It's completely pointless.

Wow. Anything but strong. Why on earth would GM even send a 5.3L truck to that test? GM should have passed on this test until a truck engine that was more focused on working than a 5.3L with the 3.08 rear end. I doubt the 3.42 would have done much better with the new 5.3 engine. This test makes it look like the GM trucks need the 3.73 & 6.2 for anything more than grocery bags.

The 3.08 rear end may not be ideal, but the 5.3 is absolutely the "working" engine for this truck, there is no doubt it'll be the one used most by those who "work" their trucks. The 6.2 is not going to be a mass production setup.

 

Also I find it amusing how all of a sudden 355hp383tq is all of a sudden not enough - majority of people posting on this site are running around in weak ass 315hp trucks, he'll the new 5.3 isn't far off in power from the outgoing 6.2

    • Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.  
    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
