I agree that a good video would be worth a million words of what the problem is and where it's located.   I filed the NHTSA complaint shown below:     VEHICLE SPEED CONTROL: 2014 Chevrolet Silver

I can't believe this post is still going strong almost 3yrs later. Glad my fix is helping others.

After noticing the gas pedal has a lot of travel before it actually starts to work, I looked at it closely. I noticed it's a very bad design. There is a plastic bracket that is bolted to the floor pan/firewall and it has two studs. The metal gas pedal assembly bolts to this plastic bracket. The Bottom right area has no anchoring, and has a gap between it and the floor pan. so when you step on the gas pedal, this whole bracket flexes like crazy. I did come up with a solution. I cut a 1/2" long piece off the end of a free paint stick from home depot. Wedged it between the floor pan and the plastic bracket on the bottom right area. super glued it in place. guess what... NO MORE FLEX. Unreal how I have to do this to a $46k new 2014 truck. Never owned a vehicle with such a poor gas pedal design. Pic below.

 

My 2017 has a different looking setup there (power adjust pedals also) but still has a considerable amount of play. Did you loosen up that bolt, wedge it in and then tighten ?

My 17 also has the power adjust pedals and I just wedged a 1/8" thick piece of rubber folded in half under the right corner. Made a huge difference.

I think I'm going to remove the pedal if it's easy and design a 3D printed spacer that will fit in there perfectly. 45ec96de2fcd66089e88d3c46b1ca888.jpg

I just did this on mine, non adjustable and it is awesome! I can't believe how much better the pedal response is. Why did I wait 2 years when this changes the feel completely. Just a 1" by 1 1\2" piece of 3\8" rubber.

OMG. A freakin paint stick fit perfect!! There is your mold.

But there's always more. Someone will want more bling; fancy materials, logo by big-shot company, etc.

We've got 3-D printing on the way!

 

Just how many pieces can you get out of one paint stick? Thanks for thinking of a solution with what you had at hand. I agree fully; the paint stick mod works perfectly.

Just checked my '14 LTZ. Now I'm looking for a paint stick! I had over 1/4" movement.

 

Gotta love the expert's explanation.....It's designed that way for vibration.

 

Some rubber washers would do that an not have so much unnecessary flex.

Flex adds to the problem by increasing the rebound/fluxiation in gas pedal input.

Like she said, "Firmer is better".

I just bought a 17 Silverado. I thought the sloppy pedal was just me adjusting from going from a Trailblazer with an inline 6 to Silverado with an 8. I'm definitely going to look at this.

Ok guys, update here regarding my 3D printer shim.

 

My plan was to remove the lower bolt (which I had assumed was attached on the back side to the firewall). Print a custom fitted shim that would go around that bolt and then when the nut was snugged down would hold the entire thing in place.

 

 

I was mistaken: as you can see mine looks differently than the OP (2017 GMC Sierra denali with power adjust pedals might be the reason for the different look). I don't think it matters which option you have, the OP hit the nail on the head with the simple "paint stick" mod. That lower bolt is not attached to the firewall, but instead it is embedded in the black plastic honeycomb bracket. That bracket is unsupported at the back (as was the OP metal bracket). With any type of pressure on the pedal there is considerable "flex".

 

Considering that a custom 3D printed shim would do absolutely nothing more than the paint stick mod (other than waste my time and cost a few cents lol) I have decided to skip the 3D adventure and just use a paint stick

 

Thank you for the super simple & easy to do mod ! You rock !!

 

With that in mind if you guys think of anything along the way that would really benefit from a custom 3D printed part, hit me up !! It's a hobby / small business of mine and I love helping out where I can !! Don't forget, there is essentially nothing we "cannot print"!

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
