2015 Silverado & Sierra to get 8-speed tran...

General Motors has confirmed that every 2015 full-size truck and suv equipped with the 6.2L EcoTec3 engine will be offered with a brand new GM developed 8-speed transmission. 
This includes the Chevrolet Silverado, Suburban, Tahoe and GMC Sierra, Yukon, and YukonXL. 
The new Hydra-Matic 8L90 eight-speed is similar in size to the outgoing 6-speed and will allow lower rear axle ratios for improved fuel economy. 
Fuel economy and additional specifications for 8-speed equipped vehicles will be announced later this year.

15 Silverado/Sierra 1500 towing capacity lower...

Jun 19 2014 08:48 AM | Zane in News

General Motors has announced that starting with the 2015 model year it will report towing capacity determined using SAE J2807 recommended testing practices. The more rigorous testing procedure has been held at arms length by the big three for years. Pickup producers have long overstated the capacity of their trucks using internal test procedures. The new J2807 standard brings everyone up to the same playing field. This means every pickup is finally being rated for towing capacity in the exact same manner from the 2015 model year forward. 
That's great news for consumers but the much more rigorous test lowers the "official" capacity numbers that many automakers love to throw around in ads.The Silverado and Sierra 1500 will see their towing capacity adjusted slightly down for the 2015 model year due to the new testing requirements. Only one Silverado and Sierra configuration, a 2-wheel-drive double cab with the optional 6.2L engine and the Max-Trailering package, will retain the prior year's rating of 12,000lbs.

As you might have noticed, we've "turned on" the new home-page for GM-Trucks.com. It's integrated with the forum and will allow us to share news and build resources better than ever before. We're very excited. 
However, we need to clean things up a little and make it look better. It's going to take us a few days, so bear with us while we remodel the place. :cheers:

GM Recalls Additional 2.42-million vehicles

May 20 2014 03:23 PM | Zane in News

General Motors has recalled an additional 2.42-million vehicles in the US. 
  • 1,339,355 Buick Enclave, Chevrolet Traverse, GMC Acadia full-size crossovers from the 2009-2014 model years and Saturn Outlooks from 2009-2010 because front safety lap belt cables can fatigue and separate over time. In a crash, a separated cable could increase the risk of injury to front seat passengers.
  • 1,075,102 of the previous generation 4-speed automatic transmission Chevrolet Malibu and from the 2004-2008 model years and Pontiac G6 from the 2005-2008 model years  because of a shift cable that could wear out over time, resulting in mismatches of the gear position indicated by the shift lever.  
  • 1,402 Cadillac Escalades and Escalade ESVs from the 2015 model year because an insufficiently heated plastic weld that attaches the passenger side air bag to the instrument panel assembly could result in a partial deployment of the air bag in the event of a crash.
  • 58 Chevrolet Silverado HD and GMC Sierra HD full-size pickups from the 2015 model year because retention clips attaching the generator fuse block to the vehicle body can become loose and lead to a potential fire.

Chevrolet Tahoe and Suburban Demand Exceeding E...

May 08 2014 08:49 PM | Chris in News

DETROIT – The all-new 2015 Chevrolet Tahoe and Suburban are once again proving why they are the segment leaders with demand for the updated SUVs outpacing expectations.

Chevrolet created the SUV segment with the Suburban in 1935, and has been the sales leader in the full-size SUV market ever since. Today, the average turn rate, or how quickly it takes a particular vehicle to sell after it is delivered to the dealer, is 17 days for the Tahoe and 10 days for the Suburban.

Part number for crankshaft position sensor

Ask the GM Technician Today, 04:37 AM
Hi, I have a little problem on my 2003 Suburban with 8100 Vortec engine.   Sometimes, it just turns off while driving, or idling, but not in any connections with use. Sometimes after a long highway drive, sometimes in city. It also happens, that the gearbox position jumps in 2nd gear and then it is problem to turn the engine on.    I've read this could be crankshaft position sensor. But to Slovenia(europe) is problem with shipping, so i dont want to order parts that don't fit.   Have anyone original part number (denso), so i can order it the easiest way?   Thanks to you all for help.

OGM-1 Navigation - Suspicion Confirmed!

Audio, Electronics, OnStar, & SiriusXM Yesterday, 08:16 PM
Many OGM-1 owners my have already know that their Navigation not only keeps the places visited history, but also must categorize this by date and time.  I have notice my OGM-1 history to be very good about keeping where I want to go at the top of the list.  Yesterday morning my suspicion that the unit must display those base on the time and location.  99% of the time when I activate the navigation I am leaving the house and rolling.  I always leave my house driving South,   Therefore my conclusion is that the unit remembers these things based on time and date.   Last week I went to a training in Tulsa (30 minutes ways) I go to this same workshop every summer...  But only once a year.  I left the house the other mooring and turned on navigation.  Low and behold the number one choice in history was Perimeter Technologies downtown.  Saturday morning I loaded up the tractor to head to Ft.Gibson to haul hay.  fired up the Navigation and the number one choice was a gravel road in Ft. Gibson....  Only the third time to ever go there... all about three years apart.  The same situation with the workshop.   I have had this suspicion because as a creature of habit I do...

truck dies immediately

Ask the GM Technician Yesterday, 07:29 PM
I have an 04 gmc sierra 1500 Z71. Out of nowhere the truck would start but killed itself immediately. The dash says unknown driver but the security light does not come on. The windows, locks, radio, and key fob do not work either. I have checked all the fuses and the battery ground and the grounds underneath the driver door, all good. I have also replaced the ignition switch and ignition lock cylinder. I have also tried to relearn the keys. I have disconnected the battery too. It is like the passlock is activated but the security light does not stay on. Checked passlock sensor and it is putting out 15 ohms and its harness is at just under 5 volts. Any ideas?

Ball joint boot....does this look normal?

2014+ Chevrolet Silverado & GMC Sierra 1500 Yesterday, 05:40 PM
I removed my lower air dam today and while I was under the truck I was looking things over. I noticed the boot on my lower ball joint on the driver side seemed almost like it was collapsed in on itself. I then looked at the driver side and it was not like this. Does this look normal? I will be going to the dealer soon so I'll have them look at it also.

Silverado vs. f150 vs. ecodiesel ram

2014+ Chevrolet Silverado & GMC Sierra 1500 24 Jul 2014
Saw an interesting video the other day about the 2015 f150 ecoboost vs. Ram ecodiesel vs. 2014 silverado 5.3L towing 7000lbs on a 3 mile 6% grade. It was a ford test so of course the ford won. But not by as much as I thought it would. The Ford beat the Ram by 45 seconds over the 3 miles. However, it only beat the Chevy by 5 seconds in the same distance. If I was on my computer I'd link the video. Honestly I was pretty disappointed in the ecodiesel, not sure what all the hype is if it performs that poorly. An interesting test would be the Hemi vs. the 5.0 ford and the 5.3 or 6.2 Chevy.

2014 Window Tint

2014+ Silverado & Sierra Accessories & Modifications 21 Aug 2013
Is the consensus that 20% window tint on the front windows the closest match to the factory tint in the rear ?    Also.. I normally get 35% on the front windows.  My understanding is you can get 5%, 20%, 35%, etc.   Do they make a film somewhere around 25-30% ?    I want something a little darker than 35%.. but not too dark like 20%

Leaking Rear Window

2014+ Chevrolet Silverado & GMC Sierra 1500 Yesterday, 11:37 AM
So I have had my truck for barely two weeks now and took it to the carwash today only to find my back seat and headliner soaked. It looks like its coming from where the top of the rear window meets the roof. The truck is a 2014 Silverado LT with a solid rear window.   Any one else had this issue? Is it a common problem with these trucks?   Kind of crummy to have an issue this big after only owning the vehicle this long.

Inconsistent transmission

2014+ Silverado & Sierra Issues, Troubleshooting, & Recalls/Service Bulletins Yesterday, 01:28 AM
Has anyone had any luck getting the transmission fixed? My truck just seems inconsistent as far as the transmission goes. One day it drives perfect and the next it will drive me crazy. Anyone experience these problems: - hard shift from 1-2.... Almost like the tranny is gonna fall out kinda hard shift - transmission feels like it's slipping when shifting from 2-3 resulting in hesitation and loss of power - shifting through gears too quickly resulting in the truck bogging down. Result is having to floor it and then it down shifts two gears. If it would just hold the gears a little longer this wouldn't be necessary. On a side note, I let out a squeaker of a fart with the seat cooler on and I thought I passed a dead animal. Note, if on date you can't sneak out small fart with seat cooler on as it effectively magnifies it and circulates it to the entire cabin.
