  1. Past hour
  2. Question. I am in the market and nearly purchased a 2019 Sierra AT4 this past weekend. It was a event vehicle and/or managers demo. I noticed that if you get in the vehicle without starting and close the door, occasionally the GMC logo on the intrument cluster flickers. very random and no pattern to it. This kind of scared me away from that specific vehicle so am still in the market. Both sales managers told me that their current vehicles do it also which surprises me. That said, when I first brought it up is sounded like they did not know what I was talking about until I caught it on video on my phone. Any thoughts/knowledge of this?
  3. You will lose some effectiveness regardless of what some say, FM radio uses line of sight, go shorter and range will be lost. Most won't notice (hence those saying they didn't lose anything) but if you use it regularly and travel outside of the area you will notice. I use satellite much of the time but use FM a good amount too for Texas country. As far as aesthetics, some place more emphasis on beauty (it is a truck not sure how that is possible) over usefulness, I am the other way. Either way mine has been hitting my door for 5 years now, no issues here. I am glad I don't a shorter one as one of the local stations I can barely pick up that goes out when I head to the east side of Dallas, I have a buddy with a shorty antenna and his doesn't get it (95.9 for those local to DFW) in my same area that I do. I can't say for sure long term it won't bother anything. You can always just trim a couple inches if reception and durability is a concern. Tyler
  4. Yeah, I saw some guys doing that to a truck in a parking lot to get it on a carhauler trailer (taking off oversize wheels and putting on stock wheels).
  5. Which ones? I believe there are 2 different sizes for the AT4 - an 18" & a 20".
  6. Mine has done it since I got it in December 18, GM knows about the issue and there is no fix yet. The only thing it does is flicker, I've noticed no other issues with it.
  7. This is what I, along with many others on this forum, run: https://www.amazon.com/KEYO1E-Compatible-GMC-Sierra-2007-2019/dp/B07KVTYYLF
  8. I have a 2005 GMC 3500 dump truck, 6.0L engine. I believe it has the 4L80 transmission in it. Pulling the dipstick, the fluid is nice and pink, smells fine, and is in the normal range. However, this is consistent behavior of the truck: start it up, let it warm for a minute or two even in the summer, put it in Drive, and drive to the end of the parking lot. Up to this point, no abnormal behavior. Then I wait in Drive for traffic to clear, and then ease on the gas to pull out on the road. The engine will suddenly rev up like the transmission is in neutral. If I ease off, you'll feel the trans suddenly load up; step on the throttle again and away you go. If you stay on the gas, the trans will abruptly slam and engage, and away you go. The minute I feel it suddenly rev, I get off the throttle. The odd thing is that once this has happened, the truck will go through all the gears as smooth as silk, with no hint of slipping or flaring or any other odd trans behavior. Once in awhile, after you drive it somewhere, it will do this behavior again taking off in first, and then is perfect. Truck has 128k miles on it. I bought it used; have no idea of trans service history. Like I said, the fluid is very clean. I plowed with the truck last winter and all was fine, other than this initial behavior. I have towed with the truck some this summer as well, about a 7k lb trailer. I'm thinking of changing the fluid and filter because it is cheap, but suspect that won't solve the problem. Thoughts?

  10. Thanks, I will when I take it back in for the window leak.
  11. Thanks guys for the quick replies. Mine is hitting the actual frame and not the door. I am glad to see we can find a good quality replacement (Craven Speed) for the Shorties....
  12. unscrew the actuator from the front diff, plug it in, then shift between 2wd and 4wd, to verify that the actuator extends/retracts. If it does, then something is busted in the front diff itself. If it doesn't (and at this point, I would plug in the old actuator and see if that works), then the actuator is defective, there's a electrical problem (fuse/short/break), or the 4wd sensor in the transfer case is defective).
  13. How come my dealer was able to quote it for me separately? I also found the part number and item online so that’s why I was asking if I bought it, if I replaced it do I need to reprogram anything?
  14. Does anyone have t1 at4 wheels they took off? Interested replacing my slt wheels with those let me know. Msg me please Thanks
  15. I listed the part number earlier in the post. Just cut out the old muffler and both flappers before installing the 3" Flow Master and a short pipe. whole thing cost me under $200 total for 11RWHP......money well spent.
  16. Looks like it actually is much more useful than the plastic one GM sells for a few hundred bucks.
  17. Have you not brought that up to your dealer? This was an issue on the K2XX trucks with painted bumpers & they allowed for a one time repaint. After that one repaint, you were on your own.
  18. Hello I’m looking at a new motor and trans for my truck. The truck currently has a 6l80 and this engine comes with the 10-speed. Does anyone know if it’s possible to run this trans. I imagine I will run the tcm from that trans but what about communications to the bcm and the rest of the truck. I have hptuners and gm dealer tools. If you can point me in any direction it would be helpful too

  20. My truck didn't come with the rear under-seat storage bins. I was cruising around the tool aisle at Home Depot today and came across these things: Tool Caddy/Organizer Stuffed one under each side in back. Surprisingly they stay in place. The passenger side could be a bit narrower though because of the jack, but it works. Removable in case I need the floor space. Best part is I can stack 'em, lock 'em together and carry them as one unit. This should do the trick until I can get something a little more custom fit. Keeps the tie-downs nice and neat.
  21. I am looking into UCA's for mine as well as considering the move to 3" and rear blocks as well? When do they expect the blocks to come out and how many miles has your kit been on?
  22. Called my local rear end place. They want 2400 to swap everything to a 3.42 or 3.73. We have a place local that scraps newer GM vehicles. They have a 2017 3.73 with 20k miles on it that I can get complete rear end assembly and front Differential assembly for 1600. Think I'm going to go that route. Swap everything in a day.
  23. Correction.... I broke off something that was on the other side of the plug. Marked in red
  24. I immediately felt the difference with the pedal. I also get like a solenoid or abs like feel on light braking almost every time I drive. Of course they can’t duplicate it. I’ve showed them several videos of it and even showed them while driving and they play dumb Example: https://www.dropbox.com/s/fulbmpy6enkayz1/IMG_4386.MOV?dl=0 Sent from my iPhone using Tapatalk
  25. ** UPDATE and a honest 250mi review** Got the truck back Saturday morning from the shop. First impression - WOW!! It almost sits like a 2500 does from the factory. It looks like an AT should. I am in love with the overall feel of it and the way it sits. The truck has an ever so slight rake to it still which I love. I need to upload pics to photo bucket and then I will post them up here. There is minor rubbing when backing up with the 275/65/20's. I was wrong about the stock 20" AT rims fitting with the Camburg arms. They hit at full lock and I am currently addressing it. I have G2 1.25" spacers on the way to see how that works out. I have delt with G2 in the Jeep world so they should be fine. Spidertrax does not make spacers for our trucks. They make a 6 x 5.5 spacer but the bolts are Toyota size (too small). I love the look of the AT rims so they aren't changing. For right now I can get away with 98% of my driving with out ever having to go full lock on the wheels. It handles a standard right or left turn just fine. The tires are fully under the fenders like stock. With the spacers it should sit how I would like. Top of the tire is under the top of the fender and slight poke from the rocker edges. Now on to the ride. I have logged 250mi so far of mixed road driving. I live in central NJ and take the NJ turnpike daily to work. Around home is back country roads that twist / turn and vary from 25-50mph. 0-30mph these shocks are meh for bumps and such. I knew buying them that they aren't meant for low speed control and are not built for it. They do have a planted feel and reminds me of my lifted Yota or Jeep. My Jeep was a fully custom Rokmen system so its not what most are used to when driving a lifted Jeep. The truck is smooth but has that feel to it we all know. You can barely notice road hum from the AT2's and I drove home last night from dinner with the wife and had the windows up. She commented that there isn't the loud HUM to them and that she approved. 40mph and over these shocks wake up. Just drove 287 where there are plenty of expansion joints, dips, bumps and pavement patches in a concrete roadway. The truck just takes it. Cruised at 75-80mph the entire 35mi stretch of TP to and from work and loved it. I love driving the truck now. Its not just a generic run of the mill truck anymore. Wife took the truck Sunday with the horse trailer in tow. Ben the Clydesdale on the drivers side and Oliver the paint/draft mix on the passenger. Yes, the wife owns a Clydesdale and rides him in a English saddle on the trails near home haha. Anyway, the truck got an approval from her and her only complaint is that it needs AMP steps or sliders to assist her in getting in. She said she was going to get them for my BDAY but I chose flooring for the house instead haha. Priorities I keep telling myself haha. The wife takes the truck quite a bit as we own a horse / chicken farm in addition to our full time jobs so her opinion does matter. She takes it once a month out to Lancaster for feed so I want her to enjoy it. I support her hobbies and she mine. With the trailer on and the boys in, it has a slight nose up rear squat to her. I notice it but its not terrible. Eventually the Firestone airbag kit will go in to help with feed runs. Between the boys, tact and trailer I would guess 4500-5000lbs. If you made it this fair, congrats and thank you! Now for the breakdown : 6112 Kit - 580 5160's - 320 5160 Mounting Kit - 80 All new GM hardware - 200 Camburg UCA - 780 Tires / M&B / Alignment / Install - 2000 Total OTD = $3960
