I used to have a 05 1500HD as you can tell by my profile name but I traded it for a Tacoma then I was never really happy with downsizing to a midsize truck. In 2018 I got my current truck which is a 2014 Silverado 1500 LTZ 4x4. It had 59,****** miles on it then and I’ve got 84,3xx on it now.  The most thing I dislike is the V4 or AFM system. 
 

I’ve found a couple 2500HD trucks for sale close by I was thinking about maybe trading towards. One is a 2014 LT with 150,000 miles on it and the other one is 2015 LT with 157,000 miles on it. 
 

Is there any differences other than looks ?  Would anyone shy away from either of these with the mileage?  I’ve never had a vehicle with that many miles.

I'd want lots of history on what has or hasn't been done to each truck at that mileage.

 

Both use the same 6.0/6L90e transmission and same controller but programming is likely tweaked some for the model year changes and what not.

 

Broken exhaust manifold bolts are very common on those trucks. So are failed torque converters. I'd want to know if the torque converter has been replaced or if the transmission has been replaced. Because if the TC fails, it takes out the front pump on the transmission which leads to a rebuild/replacement.

 

Otherwise I see fleets with well over 200,000+ miles on those trucks all the time.

Mechanically from 2014 to 2015 so frame, brakes, drivetrain, pretty much identical between the two. 

 

Obviously the big difference is the body change and interior change between the two.  The 2014 is the same as 07-13 HD, the 15 HD would be like your 2014 1500 you had.  

 

Now, this could be total coincidence but going off our history of 6L80/6L90 repairs and replacements at work, the 07-14 HD trucks I think we had all of one out for a replacement.  15-19 we've put in torque converters, some had a bit more than that like pump and 4-5-6 clutches.  Not sure what changed on the converter from 07-14 to 15-19 but something sure did.

Yeah, I’m not sure what to do or if I should pass on them. I only owe $5,000 on my current 14 (bought in ‘18), but I’ve heard so many trucks that are my generation have failed torque converters  and/or transmission issues that’s why I’ve been thinking more about going back to a HD.  Plus, if the dealer gives me what my truck is worth, I could pretty much not owe anything on the HD and it be paid for.

This is one of the pics on the 14. Does this look like frame rust to y’all?IMG_3028.thumb.jpeg.e6dc4719c665b8e2ec43bdb5c3b7b680.jpeg

 

 

Definitely surface rust at a minimum (orange/brown spots).  The grayish looking area is dried and dirty frame wax most likely.  Perhaps was a coastal truck so exposure to salty sea air?

Looks mint to me.

 

Come to Minnesota if you want to talk about what we qualify as rust.

    • Hey guys, sorry for the confusison about this. This wasn't my experainnce, it was copied and pasted fom the net. 
    • The problem with failure rates or increase failures are there’s people who don’t have a problem. What are you doing wrong they say. We had 4 5.7 GM diesel’s in the family when they came out. One was flawless. My uncle who happened to be the most abusive. Early rotary engines were known to use oil. I abused my first car so bad in six months I replaced the clutch, transmission and rear end. It didn’t use oil. My brother in law has a 2013 Tahoe and an older Yukon. The Yukon has 280K miles. The Tahoe around 175K. He runs them to about 300K. If his lifters fail before that time he would consider it a failure. My Hondas, I know people hate it when I mention them. Identical engines. One with cylinder deactivation one doesn’t have it. One shudders when the eco light goes on or off. Cylinder deactivation. But wait! According to the web. It can happen with lock up too. So now people in the know are changing the oil and transmission fluid more often. Then you read it could be a programing issue. So what do you do? There’s lots of money involved. I see three ways to deal with it. One only works if you don’t drive lots of miles. Lease, never get out of warranty. Or only buy older vehicles with a good track record. They all have bad runs. Usually when there’s a change. Even Toyota and Honda. 
    • Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/        
    • UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update  
    • GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.
