i have a 2016 silverado 5.3 turbo can someone tell me how to post pics with my phone

I cropped my pictures but kept them at the same size and resaved them to my phone under medium quality instead of high quality. I uploaded of my cell phone though not sure if your on a actual computer.

What's the limit on the 6L80 transmission in terms of power and torque limits? How is everyone's boosted Gen V's holding up?

 

GM specs say:

Maximum engine power:469 bhp (349 kw)

Maximum engine torque:439 lb-ft (595 Nm)

Maximum gearbox torque:664 lb-ft (900 Nm)

Obviously, boosting these is putting much more stress on the components and will limit the life depending on driving habits.

 

I'm looking at adding a Whipple this spring on my 2014 and just want to have all my bases covered.

Driving style dictates, my 25 year old chevy has had a whipple since new and 3 owners. One transmission rebuild in 110k miles. The rebuild was at 100K miles. A shift kit was added with the whipple. I had a vortec s/c on a 99 ford for the 110K miles I had it. The 99 was a stick and everything was original when traded in. The Ford was 5Lbs boost the chevy is 10 and still going strong.

Kinda figured.

 

It'll be a daily driver still, but the occasional WOT will still be possible.

Strange as it may sound in the in the over 40 years I'd been driving with the exception of going to the drag strip the faster the vehicle is the time of full throttle enjoyment is less. The loudness of the exhaust the slamming the gears goes buy to fast as the cars are faster to the speed limit something you'll notice right a way with the whipple.

i asked this exact question awhile back, apparently there was a revision to it for our trucks, as a 6.2 would exceed the 6l80's torque rating stock. The 2014+ 6l80's are rated for 480ft lbs.

 

That being said, I'm really not worried about it. The 6l80 has been around for awhile now, basically any naturally aspirated automatic v8 that general motors produced from 2009 on. Tons of people are pushing a lot of power through them, including vettes. I wouldn't worry much about it.

      OCI, not when but why?

      By PunchT37 · Posted

      Hmm. A real reason to not just use the odometer to determine OCI?

      OCI, not when but why?

      By Grumpy Bear · Posted

      Sad thing is that this doesn't have to be the case. LSPI can be solved without a reduction in TBN. Swap Ca for Mg.  Cats are not a issue if the OEM can get a ring and valve guide seal even at SN levels of SAPS. Dizzy is purring like a kitten with a bowl of warm milk. 200K of Full SAPS oil and zero detonation issues and nice a clean inside and out. This shouldn't be an issue. It isn't 1920.    Tell ya what AMSOIL SS is excellent at, internal cleanliness. The new formula is even a step up from their already outstanding cleanliness levels. Can't say the OEM offering is quite that clean. There marketing suggest the SS is cleaner.     That is the only defense with at shelf oil. Nothing wrong with them if you ignore the marketing and OEM 'recommended' OCI and use a thimble full of common sense. 😉 You go sir.

      Roll up bed cover experiences

      By StingerZ16 · Posted

      I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.

      Towing In Loose Gravel

      By Chuck FB · Posted

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Towing In Loose Gravel

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.
