Once you trigger the reset process, the turn signal light on each corner of the vehicle lights up to tell you where to start the programming. It was actually doing that as you were walking around the truck.
I have a 2019 GMC Denali with 41k miles same situation and I’m scheduled to carry it to the Chevy dealer tomorrow I lucked out and had 2 days remaining on my factory warranty
Good luck, mine was noticeably better after the transmission flush and the Mobile 1 Synthetic LV ATF HP. It is still not as smooth as I would like and think it should be. I just deal with it. It was recommended by some to have the engine tuned to increase the rpm when it shifted. I got a quote for $2,000 for that. I have not done and likely won't. It is a great riding truck on the highway.
I guess it is possible that the AutoCheck is wrong. I was thinking that it would be less likely for there to be erroneous additional items on the reports than for items to be left off. It is likely that I will never know. It sure makes you wonder though.
It is great so far. It stays flat and in place good. I actually have not had a need to clean it yet, but based on the material it should clean easily just by hosing it off. I think it would dry quickly too because it is light and it would not hold water.
Pretty sure CarFax has a buyback guarantee. If this wouldn't qualify, I don't know what would. That being said, there are differences between the 2, obviously, how are you so sure the AutoCheck isn't the incorrect one?
I installed a second set of TPMS for my seasonal tires and wheels, have the tool but it doesn't respond during relearn. Is there a way to wake up the sensor without taking the tire apart again?
I don't think the TPMS go to sleep, unless the batteries die. It may be possible that the tpms in your other wheels are connected and causing interference with the new ones. Have you tried far from where the other wheels are?
Everybody with a goddamn chevy or gmc is having electric and transmission problems, including myself, dealers play like oh everything is ok with your truck bullshit
I bought sierra 2020 2.7 8 Speed, it very frustrating that I face almost the same issues mentioned in the comments. Rough shifts, d to R sometimes gel loud clunk noise as if somebody hits u from the back, hesitation with different gears from time to time, when the car cold very harsh shit from1-2 and when downshifting 4-3 .,,, tried to flush oil, it worked okay for some time with some issues but never solved all concerns , went back to the same case after 100 miles ,,,,, what shit exactly are we dealing with here? … I have owned so many different car brands but I have never faced such rubbish, the issue seems universal.

DONT FORGET TO PROGRAM GEAR RATIO!!!! Pulsar LT comes with a preset Gear Ratio (3.23 I believe) which is not the proper gear ratio for some of the applicable vehicles.
Congrats welcome to the club You going to need to replace the torque converter and trans My did the same thing until it gave At 100k miles I put external radiator for transmission since it like to run hot and that’s what burns up components inside tranny
I only installed them on the rear bumper. It was not hard to install after removing the plastic corner steps form the rear bumper. I did not see where the instructions said to remove the corner steps, but I don't see how it could be done without removing them on the 19-23 GM rear bumpers. It was not hard to align. Good luck with the install.
I have the 2019 as well and it is the worst driving experience I’ve ever had. Transmission is faulty. GMC has denied it at all costs regardless of probably thousands of lawsuits by now. They used the wrong fluid with an already faulty transmission during assembly on all of these.
Not sure on the newer vehicles. But you can just let some air out to trigger the TPMS sensors and they’ll start transmitting. I put my 2008 equinox in learn mode and just take a tire chuck and go around to each tire
This tool's main purpose is to create the connection between the TPMS sensors to the car's computer. So when you get new sensors they may not automatically connect to the car's computer or if you rotate your tires the car may not realize new location. The relearn tool relearns the connection. If it is the same TPMS sensor in the tire, it may be that the battery in the TPMS has died and you need a new sensor. I don't think the relearn tool would help in your situation.
They are sold online by many different sellers. Currently, it looks like Amazon has the lowest price on it for my particular model. It's also sold on americantrucks.com and directly from Edge Products website edgeproducts.com . I would shop around these sites for the best price.
Thank you posting this! I have been looking for the simplest way to get this done without having to inflate or deflate the tires to activate the sensors.
Hi, i have some questions: What size do tires are? Do you notice any changes? Drive better after swap or the same? Im thinking, do the same ( i have sle too, but it is 3.0 duramax)
The tire size is 275/60/R20 and the tires are the Bridgestone Dueler AT. It did drive better, but at the same time I upgraded the front struts with the Bilstein 5100s that are ride height adjustable, which added about 1.5 inches of height to the front end. I was happy with them on the SLE.
I have not done anything since the transmission flush at around 42,000 miles. I am at 60,000 miles. It is not terrible, but certainly not as smooth on some of the shifts as I would like it and expect it to be. Sometimes it shifts fine and it seems to shift better when it is cold. I am done with asking the dealers service dept. to do anything as they will say they did not feel anything. I may take it to have the performance tune done to increase the rpm when shifting. I have heard that could help.
Me too. Total crap. Truck been in and out of the shop on its 4th month. First the Torque Converter. Then the Transfer Case Sensor. Now it's back in again for a valve body replacement. It's been shuttering and hard shifting since I bought it. I didn't drive it too often and tried to live with it, but it needs to be fixed so finally took it in for repair. All highway miles 30K miles on a 2021 AT4 5.3L 10 speed transmission. Dealership is slow as fuck about each stage of repair. It's so painful watching them crawl like snails. I wish I was rich enough to auction it off and buy a different vehicle. I have no choice but to play these stupid games with GM. This will be the last time I buy a GM product. I spoke to several transmission shops, all of them pointed out that they would have each of the repair phases completed in a week, not 3+ months. The cost of parts and labor actually wouldn't have been too high either. But the shops told me they won't touch it while it's under warranty. Also, recently changed fluid in the front and rear differential and the transfer case before I took it into the dealership.
Having similar issues, mine seemed to start after a battery swap and my truck is at 80k miles, did a lot of googling and most people with this problem either got the transmission fluids flushed and replaced to solve the issue while others had the transmission computer de-learned/reset and solved the issue, considering mine started after a battery change i think mine falls into a computer issue, taking mine to the dealership tomorrow for the fix. Curious if you ever got your problem resolved and what your fix was
I had the transmission flushed and the Mobile 1 LV ATF HP Fluid used. Having this done definitely improved the shifting, although it is still not as smooth as I would like it to be. Ironically it seems smoother when it is cold, which is not what I would expect. The only other option I would consider, which someone did recommend, would to be to have it tuned to increase the rpm when it shifts. The thinking is that would give a smoother shift. A tune shop in my area quoted me $2k. I am going to deal with the not so perfect shifting for the time being.
I have a 2019 siverado 5.3l my transmission changes out good with no problems but every once in a while when am slowing up to stop the transmission gives off a loud clunk noise as if like someone ran into the back of my truck it don't do this all of the time but it do it a lots in the summer time a lot of times it scares me because i be thinking someone done ran into the back of the truck. I don't believe its the rear end i believe its something going on with the torque converter as if it catching up with it self after braking if anyone knows what this is explain it in response on my comments reply.
Mine has the same issue. I am also looking for answers. If I ride the brake slowly I feel it. If I push the brake pretty hard when coming to a stop sometimes it won’t do it. I already changed the torque converter and got rid of the shudders while shifting. Trying to figure this issue now
@@flyonawall6521 correct the rims are not stock, although the vehicle previously belonged to my son, and yes, the sensors were put in the new wheels, although that is a very important point that you brought up and thank you
Will this tool work if the tire sensor is actually defective beyond being able to reset? Reason I ask is it worked 1st time. Message came back in 45 miles later and can’t get the tool to reset same tire again..,
If it's old.. the batteries do run out eventually. You'll likely need to get another one mounted in your tire--- and then use your tool to reset the new one.
@@calholli vehicle is 2008. I am sure batteries are done. Wished there was a way to eliminate the alarm. As I operate my tire pressure gauge all the time. Old school. Ridiculous sensors
@@daveholte7658 There is, you just have to invest in a scan tool. Launch x431 variant, xtool d8, topdon, thinktool pro, autel. There are a lot of options these days, that are well worth it
Get put from under the pos . I litteraly know 2 people who had there 2019 gmc bought back from gm for the shitty tranny . Knowen to be junk . Both come out smelling good on the deal 1 drove free for just over 1 yr 36k on the truck and over 18k on loaner trucks and guy a full refund . The other just under a yr and 19k mi on his truck and 6k on loaner trucks full refund . 1 moved to 2500 oil burner gmc other to a 5.0 f150
