A question here.

I put my winter tires and wheels fromy 2019 Silverado 2500HD onto my new 2021 Silverado 3500HD  and the truck will not read the TPMS sensors. The tire shop said the dealer needs to reprogram the sensors to the new truck. Took it to the dealer and they say that this cannot be done even though the TPMS part numbers are identical between the years and that I need to buy new sensors for the new truck. Any help would be appreciated as this makes no srnse to me! Thanks in advance.

Like I said, they are the SAME PART NUMBER, both 433mhz, no difference.

Ya, If they were programed to a different MHZ, you cannot program them to a different one after. What is the part number for the sensor. 

 

If they were programmed to 315MHZ then they cannot be changed to 433MHZ (and vice versa) and a new set of sensors will need to be ordered.

13528563 part number for both trucks. Both 433mhz. FACTORY sensors from the 2019, not some cheap aftermarket chinese sensors. Sensor tool reads them fine, but will not register to the 2021 truck. Dealer just says I need to buy new ones, no other explanation.

That's weird. i would run it down to Americas tire(discount tire and see if they can do it. assuming the tire shop wasn't Americas tire/discount tire). Keep you old set of tire with sensors at home( away form the vehicle).

 

They will do it for free and it will take a few mins.

They were the original tire shop that said only the dealer could re-register the sensors.

You can buy a cheap relearn tool for $10 that will do both 315 and 433MHZ. You have to put the truck into learn mode and then use the tool at each sensor and it will honk the horn when it is learned. I've done this on my 2021 and with the 315mhz sensors numerous times on my 2008 Avalanche.

If the dealer and a tire shop cannot do it with professional gear, how is a cheap tool going to help? LOL

 

 

Do you have the VIN from your 2019 still?  

 

Did they break down the bead on the 2019 wheels to verify the sensor # and frequency?

I've dealt with enough idiots that are "professionals" and can't fix crap that I've been able to fix myself. It's not rocket science to pair sensors if you follow the correct procedure and the sensors are indeed the correct matching frequency.

Yupp -- and newdude is trying to get the OP to verify that the part number/frequency for both sets of sensors.

Some part listings show multiple part numbers for the years in question. 

Verifying what they are may help determine the solution -- and determine if the dealer is correct that new sensors are needed.

 

No matter what tool is available, if the frequency of the sensors does not match the frequency of the vehicle they will not be able to be paired.

 

Of course, this is why many tire shops use dual frequency sensors.

Slightly higher sensor cost, but then it doesn't matter what the vehicle frequency is.  Great convenience to the tire shop.

      Hello, I’m thinking about putting a six inch lift from superlift on my 1999 Chevrolet Silverado 1500 4wd, extended cab. My question today is what would be the recommended wheel size (both tire and rim) for this setup and I’d like it to preferably stick out on the side a bit but it’s not needed. I know many run 35” but again I’m not sure.

      Hello, looking to upgrade my rancho stock shocks to bilstein 5100 shocks but would like to level the front end. Could anyone please tell me which ones I  need to do so? Is there a certain series other than just the 5100? Also what would be the best place to purchase as far as best price.
      I have 2016 chevy silverado z71.
      Thanks for any info!!

      Hello!
         
          First I’d like to say that I’m new here and not sure if I’m in the correct place to be asking this or not, but I am in need of serious help with this engine...
       
      The truck is a 1999 LS silverado 1500 with a 5.3L vortec v8 lm7 in it. 265K miles.
      When I first got the truck this wasn’t an issue it just progressively got worse and worse until it just did it fully 24/7.
      I know this is a very common issue with these engines, but the symptoms I’ve been having are not the same as what Ive been seeing other people having.
       
      The truck started having a low oil pressure problem, where it would be fine when cold full around 25-30 psi, then as it warmed up / as I drove it, the pressure would slowly drop until 0psi, sometimes this wouldn’t happen till after driving 50+ miles, sometimes it would happen in 10 miles. Now after replacing the pump it does it in literally 1 mile. After it would drop to 0psi the lifter chatter/tap/knock (whatever you want to call it) would finally start up. I would stop the truck kill the engine then restart it. Most of the time after id restart the engine, the pressure would rebuild back up (lifter tap would go away) and I’d go for a mile or two, and then the whole process would just repeat itself. 
       
      Make a long story a bit shorter... 
       
      I ended up replacing the oil pump, with a mellings 295 pump, cleaned out as much gunk as I could, got the oil pan nice and squeaky clean... The truck did fine for a couple hundred miles, had really good oil pressure. it did lose all oil pressure entirely on my first test drive but it never had a lifter tap or made any noise when that happened I just pulled over killed it, started it back up and bam it had normal oil pressure.... After that happened, the truck did fine for a couple hundred miles, then out of nowhere it would just randomly start ticking even when it had OK oil pressure 15-25 psi.
       
      Prior to replacing the pump when the engine was cold it wouldn’t even build up oil pressure right after starting, usually took like 10 seconds + of it running for it too build pressure. And it would only build up to about 25psi and it stayed there even when warm. Now after the oil pump replacement, when the engine is cold the oil pressure will build immediately and be at around 60 psi, then as it warms up it slowly drops to 40, I’ll get out onto the road and as I barely make my way down the road, it slowly drops until it gets down towards 5-10psi and then the lifter tap will start up, doesn’t usually drop fully down to 0 like it did prior to the oil pump replacement. It usually atleast has a couple psi, but that ain’t enough obviously lol cause it’s ticking.
       
      When it does this, I have no choice but to pull over, kill the engine, start it back up, and it builds back a little bit of pressure. But it still has the lifter tap it doesn’t go away like it would before “sometimes”.... And it’s bad, I can definitely feel a power loss, also can notice a change in the way the engine sounds other than ticking, like a ****** in the timing or something? I know it’s NOT good and the ticking means there’s no oil getting to the head, so please save the lecture, please...
       
       I’m just at a loss as to why this would still be happening after replacing the pump? The pump doesn’t do what it did before I replaced it, which was, it would fail to build pressure after starting the truck when cold, that’s what made me think the pump was failing so I replaced it, and the new pump DID fix that issue... lol but that’s it... so I know it can’t be the pump right? I mean it’s literally brand new... I also tried to make sure the o ring wasn’t pinched when re-installing the pump... 
       
      I really just need some good insight on this issue from someone that knows these engines well, this is killing me! This is my only vehicle I need to get this figured out ASAP. I did all the work myself, 23 year old guy, grew up working on bikes then transferred over into cars/trucks, not an expert by any means but I’m no dummy that’s forsure hahahah. Any help is appreciated!
       
      & The truck is a great truck, it’s an all around clean truck, the last owner definitely took care of it, so it’s not like it’s a big ass pos. Well kinda I guess lol..

      So around this time of year last year I changed my brakes and my rotors and was going to replace my front bearings as well. My 08 is a Michigan truck so it’s got a plethora of rust accumulated. One of caliper bolts had seized so I completed what I could with the brakes and headed home to figure the best attack for a seized rusted bolt with thread lock. Anyways that bolt was a ******, so I went to my brother cause he had an air compressor and thought we’d try that. Needless to say the bolt one, so my brother put the wheel back together but before he put the caliper back in place over the rotor he decided to decompress the spring?. Why? I have zero idea thought it was pointless for him to do that Considering I had to do it to change the springs. So I start to head back home just worried about getting this bolt out so I can change my bearing. So as I start to leave I don’t notice anything out of place until I get down the road and my brake pedal goes to the floor. It made no sense, I couldn’t figure out what happened in the 30 minutes I was there; that would take my brakes from having good pressure to having none.  Then not long after that my fuel pump goes. Old Murphy’s law coming in clutch for me! So I get the fuel pump swapped get the caliper freed so I could replace my bearing. Then go to bleed my brakes and I can’t get any of my brake pedal back. I have abs so I I went out and bought a scan tool cause I heard bleeding brakes with an abs system without the scan tool is difficult and is more than likely the reason my brakes still go to the floor. So I do everything the device tells me to. There’s no change, except now I can’t shift it out of park to even attempt to check if there’s at least some pressure. I’ve been battling these brakes so at least the last half of 2021 my family is telling me to just sell it for whatever. Honestly I don’t want to sell it I rather enjoy having it and am not ready to let it go. Any help or advice would be so appreciated!

      I have a 2017 Silverado 5.3L. Used to stay around 40 pounds of oil. Now when idling, is goes down to 20-25 ish pounds. It’s not throwing any codes up but does have a bit of a knock if I floor it without letting the pressure build back up first. Cold start it’s just below 40 pounds but at operating temps (210) it drops like crazy. It’s not oil quality or level, I just changed it last week and it was good for half a day and went back down.
