I recently purchased a 2014 Chevy Silverado LTZ 4x4 with the 5.3L V8 with 98k miles. Checking out the vehicle everything seemed great; 1 owner (old man), well kept, flawless interior and minor exterior flaws, drove great and made 0 abnormal noises when Idling or driving. I’ve reached the 1000 mile mark after purchase and the truck makes plenty of ticking noises at idle, slipping gears when applying low throttle and now the transmission light came on. See this is happening with so many of these trucks and I hate that I’m getting screwed because of it. I’m afraid the truck won’t be able to get me to and from work and I badly need help with this.

Caveat Emptor

 

Did ya pull the trans dipstick when you looked at it? Look at service records? Look for TSB's>

 

Anyone buying a K2 with a V8 and a 6-speed ought to be aware of the torque converter issues this combination has and the timing of failure events. Old boy got rid of it about on the money. As you've continued to drive it the pump is now likely toast as well. This is going to take a rebuild or replacement and I'd go for the later and a Florida Billet Torque Converter in stock stall. Welcome to GM trucks. 😉 DO NOT let them reinstall another 'factory' converter. Add more cooler and have a 70C TBV installed. It will outlast you and the truck.

Yep, gotta love GM and their low-bidder driveline components. They'll never change! Happened on my '07's 4L60E, happens with the newer transmissions & models, and is STILL happening with the '19 up junks.

 

If you plan on keeping the vehicle and need it to be reliable, you'll have to work through the failures as they come, and after doing some research, replace the parts with stuff 100x better engineered than GM could possibly muster in the 21st century. 

 

I had to replace my '07's transmission at 103k miles after 3rd and 4th went up in smoke without prior warning. Fluid was still as red as the day I flushed it through, 50k miles earlier. I went with a PerformaBuilt transmission, and was VERY happy with the transmission, their workmanship & customer service. Not sure if they build anything above a 4 speed, but I highly recommend those guys.

 

Even if they don't, a phone call to them might get you pointed  in the right direction. Eventually they'll start building these, since there's going to be plenty of failures, and the 4L60 & 80E's are going to age out like the TH350 / 400 / 700R4 did.

    • Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks
    • My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.
    • I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing. 
    • get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.
    • This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.
