Hey guys I’ve got a 2014 GMC Sierra 2wd 4.3 v6 on a 7inch lift 22x12s and 35s the trucks got 3.23 gears in it and when I bumped up to 35s from 33s it seems like it is always constantly searching for gears on the Highway or above 50mph I get around 13 mpg and I would like to retain that or get better if possible and I’m trying to decide wether regearing the truck would be worth the money and also what gears to go to If I get it done if 3.73 or 4.10s would be better I would like to retain as much gas mileage as possible but not have the truck struggling 24/7 when it hits a hill it just sucks the life out of it or on the highway trying to maintain a decent speed I have a cold air Intake exhaust and Diablo tuner please lmk what y’all think438e023f7bec8ca1d68c355f4fe6fe65.jpg

I think the consensus on these trucks is 4.56 when running 35s.  I have the 6.2/3.23/ 8spd and haven't regeared yet and I'm not really sure I need to.  The truck hauls ass still.

Truck looks good Dave.
If you can afford it do it.
The v6 has to be struggling with those tires.
Does the tuner help any?

My problem is that motor I’m just trying to find ways to get it back to how it was so you would go with 4.56 gears?

I wouldn't put any more money into that truck I would buy something more appropriate. You'll be lucky if you can break even on a sale.

I know I’m not going to break even with this but this is the truck I could afford at the time and now I’ve got it so close to being payed off it it would be stupid to get rid of it I’m gonna run it till it blows

Try this. Get out on the open Interstate/Highway and run in M5. Put her in cruise control and observe. This little exercise will let you know what it would be like to run with a 4.10:1 diff in high gear. See how much help that step is. A test that cost you nothing but time.

Thanks man I will do that and my biggest issue is the truck is always and I means always Reving up in the rpms to move like jumping the Rpms it will never just cruise and I can give it a little without it jumping in rpms to try to move

Needs 4.10's at a minimum for 35's.

 

2WD makes it's easy and costs way less than if you had a 4X4. You need to tune for that as well. It will adjust the shift points for the transmission.

      Clunk when putting truck into drive and reverse.

      By Matt Parker · Posted

      I have a 2000 Silverado 1500 LS, whenever I put it into reverse and also in drive it clunks, the truck also feels sluggish when driving. Any advice/ideas ?

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.
