I mean they already get shitty fuel mileage emoji2375.png

That they do.  When i first got the truck drove it from va to ny saw best 15 mpg on 87.  I run e85 and get a best of 13.  Thats all highway, city mpg sux.  Im wondering if 93 would be better.  Shitty thing is its 2.69gal vs 1.49 for e85

So heres my update on the gears . Just dropped the 5th wheel upstate. 120miles 1 way all good. She did good, only struggle a little on the 4 mile 5% grade climb. Had to drop to 50mph so i wasnt screaming over 4k rpms. Got 5mpg on the way up towing 15k lbs. On the way home an hr into the drive got a p0700 and a p0741. Cleared the code. A hr and half later i get locked into 4th gear no cel. Get home hook up scanner and p0741 is in the history. This has been happening for 2 yrs. Thought it was my tune, put stock tcm tune in and changed fluids and filter 3 months ago. 15 2500 6.0 62k miles. So now gonna get trans looked at, been dealing with this issue for 2 yrs and finally got a code.

don’t wanna be a jerk but i will say this.  i love working on and modifying vehicles, but i don’t mess with new stuff.  i have a 72 k10 with a 396 and a 65 goat, always messing with them.  my 2016 2500hd?  bone stock.  no tune, tiny 245/75r17 tires, nothing.

 

i would love to drive a lifted truck with bigger tires, a tune, maybe even a supercharger.  but i ain’t messing with my 2016, because i rely on it and don’t want any problems.

 

if you wanna play, i think there is a lot to be said for finding an older second rig to mod and keep your newer truck stock.  just how i handle things myself.

 

good luck, OP.  hope it works out.

My issue started out prior to me modding. The new gears were to help to my 5th wheel. These trucks should have came with 4:88

      OCI, not when but why?

      By Chuck FB · Posted

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      Tranmission stays in Low

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      By asilverblazer · Posted

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.

      Stabilitrak conversion to Z71

      By asilverblazer · Posted

      Stabilitrack was a stability control, traction control system, that functioned independently from the transfer case.   Z-71 has nothing to do with the transfer case or differential.   If it does have an AWD system, my memory recalls this being specific to the Denali trim, converting won't be as simple as swapping out mechanical parts like differentials and transfer cases. It will require reprogramming at a minimum. Long story short, not likely worth it.   Pulling a fuse, may disable the AWD system, it might also prevent any other transfer case functions.   However, the AWD case was generally based on the same transfer case you refer to in the 2006 Suburban. If it still has a 4-High and 4-Low where the transfer case locks and splits power 50-50 front to rear, what are you gaining by changing anything? A true-rear wheel drive only, what good will that serve? Not enough to go through the trouble of changing out all the parts.    Generally, all the factory systems will handle a 33" tire and re-gearing. Probably a 35" tire too, if you aren't driving like a caveman. If 35" tires are in the plan...   If you do plan on driving like a caveman or are fully committed to 35" tires, an entire re-think of the build is probably in order. Starting with square one, an IFS front end isn't going to be the best starting point for 35's and caveman driving.

      Oil Consumption

      By PunchT37 · Posted

      1/2 qt over full ain`t gonna hurt $h!t. Most times, a whole qt won`t either. Most have windage trays now. As long as the crank isn`t slapping itself in the oil, it`s not the end of the world.   We used to overfill 1 qt at the track, at race time. Better to have it over full than having the pan sucked dry at 6500 rpm`s.
