  1. You'll still need the paintstick, or whatever you found that works, because the structure that the pedal mounts to will still flex on the bottom with a new pedal. My picture in the first post showing half a clothespin jammed under the pedal mount demonstrates what I mean. I'm glad to hear that some of you are having success with this relatively cheap swap. I'd love to have something that could program my pedal to have even better response but I continue to balk at the $300+ price tags.
  2. Brews, Sorry to hear of your trouble. I looked up the part number for your '14 and, regardless of whether you have a V6 or V8, it lists 23362231 as the correct pedal for your truck. Perhaps you have a bent pin or just a defective part?
  3. Csjumper2003, OP here, the pedal replacement made the first 1/3 more responsive for me. I really noticed it when I was running a bunch of errands the other day which is why I finally wrote about in the forum. I also have experienced fewer low-speed hectic shifts as a result of this responsiveness. As I mentioned earlier, it's not a complete remedy but it helped. Does anyone have a factory service manual for one of these trucks who can verify the replacement procedure and see if it mentions needing to program it?
  4. At least I know they started using the part on 2015s now. I certainly don't want the new part number to be seen as a panacea for acceleration complaints, instead I merely wanted to share my experience of improvement...however small. Hopefully another 2014 owner will try the swap and report. You 2015+ guys just don't know how good you have it, haha.
  5. I certainly understand waiting. I wish I had some additional information on what changed between the part #s. My old part wasn't defective by any means but something in the internals of the new part has made the initial throttle response less anemic. I do know that, given their recent shenanigans regarding superseded numbering, any change in a GM part must result in the issue of a new number.
  6. I updated my post again to help distinguish between the pedal assembly and the metal housing to which it mounts. It wasn't very clear before. The pedals are identical on the exterior except for the part numbers. To more specifically answer you question though, the pedal assembly bolts to that formed sheet steel box that's notorious for flexing so unfortunately that problem remains. In my picture, which contains the new part installed, you can see that my clothespin is still in place. And it still does a great job of preventing most of the flexing. You really do get to see how cheap that steel part is with the pedal off. I wished I had a welder to stiffen it up when mine was off, it's ridiculously flimsy.
  7. I updated my post to include a picture and procedure for the swap. As far as programming, mine was plug-and-play. Hopefully that is the case for everyone who tries it.
  8. Like many of you, I was affected by the faulty high pressure a/c hose design on my 2014 Silverado. Fortunately for me it was only February in Texas and I barely needed it. Even more fortunately though, I still had 80 miles left on my CPO warranty so I didn't have to haggle with the dealer about repair costs. We'll see how long my condenser cooperates as I figure it's next to go on the A/C system. While my truck was in the shop the dealer loaned me a fully-loaded (of course) 2018 Sierra with a 5.3 for a day. Once I got over the Sierra having just about every bell and whistle my rig didn't have, I noticed just how good the acceleration was compared to my truck. So much so that I was convinced that GM had bumped the horsepower/torque ratings between 2014 and 2018. Once I verified that they hadn't, I went on a fact finding mission to figure out why this truck drove like a beast on acceleration while mine felt like a 4 cylinder. I had researched buying a pedal controller to see if that would help my lousy tip-in on acceleration but simply could not justify the cost. I did know that I was tired of the lackluster get-up-and-go of the first 1/3 of the pedal travel of my truck--especially after my experience with this peppy loaner. The first modification I made to my truck after buying it was to shim under the lower portion of the metal assembly that the accelerator pedal attaches to as I had been following this forum and knew it had been identified as a problem. I opted for using half of a clothespin which took 99% of the flex out of the pedal assembly, so I knew that was not my problem. Instead, I crawled under my loaner 2018 Sierra's dash and took a picture of the part number on the gas pedal assembly--it was GM# 23362231. Once I got my truck back, I peeked at the number on its pedal assembly and it was GM# 20972082. After some research I could not determine when this older number got superseded, but I knew if the price was right I'd buy the new part number and see if it helped my truck. I picked one up off a well known auction site for about $54 and installed it the day I got it. I waited almost two months to share this because I wanted to verify that it improved my acceleration for real and not just in my imagination. I can definitively say, for my truck, that the initial acceleration has improved noticeably. I will even go so far as to say that the low-speed transmission shifts that seemed to startle the truck into what I would call "panicked shifting" garbage-truck-style have improved about 80%. Once I get a my valves cleaned by a shop that has the BG cleaner I think it will accelerate like the 2018 I was loaned. The swap of the pedals is pretty simple. Two 10mm bolts on the lower left and upper right as shown in the attached picture. A 1/4 inch deep well socket with a small extension did the trick. The upper right bolt is a bit of a stretch but not too bad.I unplugged the old one and plugged in the new one and put the bolts back in. I did not do a side-by-side multi-meter test of these pedals to verify the voltages with pedal travel because I did not have an electrical diagram of the several contacts in the wiring harness connector on the pedals. I started to try and it was simply futile. So I just installed the new part and took it for a test drive. To repeat, the new GM Part Number is 23362231 and it worked for my 2014 Silverado with the 5.3. I hope that these results can be duplicated (and enjoyed) by you folks in the forum. I like my truck a lot better now since this "upgrade." If anyone else tries this, please report your results!
