2014 Chevy Silverado Transmission

[Tannerivey8]

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.
